View Full Version : TB42e to TD42t Conversion - Lots of pics!

Hey guys,

I've recently started a TD42t conversion so I thought I'd post up a progress/how to/question thread.

I'm trying to take as many photo's as possible along the way.

I found myself a cheap TD42t GQ silvertop with 220,000 on the clock. It has a DTS turbo kit and a straight out 3" exhaust.

The original motor in my 1996 GQ is a TB42e duel fuel (petrol/gas).

47739


I started out by stripping the electrics from the TB.

47740

Intake and airbox off, plus some more wiring.

47741

47742

Once everything was unbolted it was time to lift the motor out.

We had a great deal of trouble trying to get the exhaust unbolted so we cut it off.

The top gearbox/bellhousing bolts were a pain to get out but thanks to a persistent brother and a few Bundies they came free.

47743

After a bit of a struggle, taking a spotlight off and letting the tyres down the motor was out.
47744

47745

Once the motor was out we went about stripping the unnercesary petrol/gas parts from the engine bay. Things such as gas loom, charcoal canister, ULP breather line.

I also had fun crawling under the dash and removing the in cab dash wiring and pissing off the old, broken cruise control system at the same time.

Update time!


I started by finally removing the rest of the TB exhaust.
47746

Followed by the gas line that runs along the chassis.
47747

I'm still struggling to get the last bolt out of the gas tank. I've moved onto other things for now.

Now the fun starts! A picture of the TD42t before dismantling.
47748

Intake and second battery tray.
47750

Radiator removed (you need to use the TD radiator as the inlets are on opposite sides).
47751

Continued below...

Chipping away at disconnecting the loom and bolt ons...
47755

I didn't get many photo's of removing the rest of the parts as it's not overly interesting.

Notable mentions from this stage:

Thankfully I could disconnect the exhaust just after the dump pipe so I didn't have to worry about disconnecting at the turbo
The bellhousing bolts were once again a right pain in the gluteus to remove. Easier to get to than on the TB though as it didn't have as much **** in the way.
The bellhousing took quite a bit of praising to get it to detach from the engine. Lots of vertical force and a jimmy bar helped.


A convenient hole made getting the left hand engine mount out easy.
47756

Getting ready to be lifted out.
47757

Always needs more WD40..
47758

47759

And lift!
47760

Here it is in all it's glory!
47761

Next step is to slap in my new Exedy Tuff clutch and rear main seal. After that the real fun begins!

I've done a little bit more since those last pictures. I'll update when I'm at home.

I'm at the point now where I decide if I want to use the TD loom or modify my TB loom.. We pulled out the TD loom last night. It's a big messy job.

Does anyone have any advice as to which way I should go?

Cheers.

Nice work !! Stay with the TD coz the tb one is chopped to suit the lpg and it should be just a quick plug and play. After you inspect it from breaks it would be a good idea to go over it all with electrical tape to help protect it

Chappy
1st August 2014, 02:40 PM
I've made the decision to go with the TD loom. It's a big job, especially pulling apart the dash but it's pretty easy work that I can do of a night time.
I think I'd regret not doing it the correct way once it's all back together. The TB electrical system has always given me dramas so I don't need any of those rearing their ugly heads again down the road!

The loom will interest me as I have the front part of the loom for the engine bay and dash then the rest is cut....?

I will need to sit down when I get my car back home to figure out whats what on mine

I cut the donor loom just behind the front seats. It unplugs under the passenger seat but then another branch continues along both sides of the car under the carpet. I'll replace mine from that point forward. I'll just wire it in. I figure it should all be the same.

Time for an update.

Had a few days break as I've been busy but now I've hopped back into it.

Replacing rear main seal
47943

New Exedy HD Tuff Clutch
47944

As I have a complete diesel loom, I made the decision to swap out my EFI loom for the diesel to save me trouble in the long run. It's a big job but hopefully it's worth it.

I started by removing the dash (annoying to do by yourself)
47947

47949

47948

47946

The two instrument clusters

Tomorrow I should hopefully have the EFI loom out and the diesel in! Then it's just a matter of putting the motor in and wiring it up.

I'll keep the thread updated.

Thanks guys..
I'd estimate with everything; Engine (with turbo kit + exhaust), clutch, rear main seal, diesel return line (broke somehow), oils, filters and other fluids it would be around $5000.

Thankfully I was able to source the loom, diesel lines, diesel tank etc from the donor car.

The loom I scored the other day is a straight plug and play set up with my existing loom.... happy days.

7th August 2014, 05:10 PM
I spoke to my contact and when I mentioned the trouble you were having and asked if he had another series 2 loom he said "Good luck" and said sell him yours.... to which I told him "Not bloody likely "

A few of the boys will be over my place on Saturday so pop around and have a look at my loom and see what the go is.. maybe bring your one along if you have not started fitting it.

Update!

Slowly progressing.

I've had a few frustrating set backs. The gas tank did not want to come out so brute force was used. I ended up attaching a snatch strap to it and getting another GQ to pull it out. Worked like a charm.

The clutch release fork was another annoying set back. After a few days of agony I realized I had been going about it the wrong way. It's finally in though.

After making the decision to swap the looms, I stripped the interior only to realize it wasn't going to work as the diesel loom I have is a Series 1, whilst mine is a series 2. I would have sacraficed a bit of functionality so I've gone back to the original plan of adapting the petrol loom.

Diesel Loom

Cheers guys! I was up until almost 2am last night putting all the interior back together so that's one less job to do now.

Picked up necessary fluids today so hopefully tonight I can get the majority done.

Tonight I plan on:


Finishing power steering
Radiator coolant
Putting in diesel tank and hooking up the lines
Replace injector return line
Bolt up starter motor


Then that's just going to leave the wiring to do. Hopefully that's not overly difficult (thanks to Rossco's tips)

Last night I ended up swapping out the broken engine mount, replacing the injector return line and started to plumb in the vacuum hoses and fuel filter. All these little jobs take so much time. I think my goal of getting it running by this Sunday is a little ambitious.

Big night tonight, a few rums and some music and I smashed out the progress.

Figuring out fuel lines took me a little bit, also mounting the filter. The vacuum lines were equally confusing but thanks to Rossco's conversion pics I was able to figure it out.

28th August 2014, 09:03 AM
Thanks guys, It's refreshing knowing that the end is in sight. Few little fiddly jobs left to do though.

I'm a bit concerned about the fuel lines though. I have a long range belly tank which was my petrol supply when I was running duel fuel. I'm not sure how I go about making sure that supply isn't used by the diesel (rear) tank is? I also need to open up the lines as they have been crimped off after the shock tower when the gas was installed.

Rossco
31st August 2014, 11:32 AM
Fuel lines should be right. Just open them up and give em a good blow out. I just ran fuel hose between the tank and where they had been cut.

I'd just get the main tank hooked up to get it running then sort out the belly tank with transfer pump and dual filler neck. You can always do this later down the track when its up and running, but works out pretty well the range is pretty good. . . Especially compared to gas!!

Bloodyaussie
31st August 2014, 05:12 PM
This is what I did when I removed my gas ... just pay attention to where you route the hose as you dont want it rubbing or getting squashed.

Chappy
31st August 2014, 08:18 PM
Cheers guys. Just have to figure out which color wires from the loom are used for the 3 wires on the fuel level sender.

Chappy
31st August 2014, 10:25 PM
We have liftoff! Finally running. Few little things left to do such as bolt in the diesel tank, bleed up the clutch/power steering and wire up the manual glow circuit.

Should come out pretty easy with an easy out. Worst comes to worst support the engine and take that mount off. Bummer.

Yeah a bit of googling tells me the same thing. I've read the straight flute easy outs are better for brass than the spiral ones. I'll do a ring around tomorrow and try and find someone that sells them. Then I guess it's time for a new fitting and oil feed line. Probably not such a bad thing anyway.

You'd be amazed sometimes if you put a flat head screw driver to it and will turn..

I rang a bolt removal guy to come out and remove and engine bolt and he told me over the phone what to do and it came out easy and did not cost me a cent... top bloke.
If you do try it be gentle, its when you start butchering things that it starts turning into a head f#$ k.

To be honest I'm not sure what I should ask for it. It's in good nick, I have all new belts sitting in garage for it. Just had plugs replaced and leads. I'm reasonably sure I'm the second owner of the car, I bought it bog stock from an old gentleman who used it as his daily. Serviced every 5,000 since I've owned it. Never had any dramas with it. Only reason I got rid of it was I want to be able to take my GQ swimming and across country.

Just one thing, you might want to pull your oil feed and return lines off and give em a good flush/blow through before you reassemble everything, had a mate destroy a brand new turbo because he forgot to double check the lines and it lunched itself due to oil starvation from a simple blockage.

Big update

A big thanks to Bloodyaussie the bloody legend for grabbing me a new turbo oil feed fitting.

Today was the day that the project finally came together. Dad came over for fathers day and we smashed out the remaining jobs.

Today we:


Fitted the exhaust
Bled the clutch
Installed and wired the diesel tank
Removed remaining gas parts
Drove it!



https://www.youtube.com/watch?v=HJ9fHn2JJaM&feature=youtu.be

I have a small issue though. After driving and parking I noticed an oil leak. To me it looks as though it's coming from around the oil filter area? I haven't touched the filters yet and they are tight. Any ideas? When it's idling it doesn't seem to leak, only when driving around.

How do you like it compared to the old motor?

Hopefully the oil leaks easy to track down. It's hard to see in the photos, could be rocker cover.

Chappy
8th September 2014, 08:07 AM
Thanks mate. Feels good to have it finally running. I don't think it's the rocker cover. Only seems to be wet underneath the filters.

Edit:

I just remembered that I ran the rocker cover breather hose down that side of the engine. It could be that pouring oil out? I'm at work so I can't check until I get home..

Chappy
10th September 2014, 12:01 AM
Quick update.

Oil leak was not from the rocker cover breather which is good, means no blow by! I think it was coming from the back oil filter as it was really wet underneath it and it only happened when the car stopped, not when it was running (which leads me to believe it was the filter o-ring).

I gave her a service with new oil and filters. I'll take it for a drive tomorrow night and see if that's fixed it, fingers crossed.

I've almost got all my wiring sorted out. I grafted out the wires from the TB harness for the coolant temp gauge and warning light so they are now functional.

I also swapped my oil pressure sender from the TB to the TD as the TD didn't have an oil pressure gauge, only a warning light. That now works perfectly on the dash.

I now just need to figure out how to get the tacho to work. Any ideas?

Here's a few pics of the wiring.

Looks bloody good.

I think you just need to run wire from the two pins on the back of the tacho to the engine speed sensor on the front of the motor. Think thats all there s to it, I got patrolapart to do mine. . . That's another option if your feeling lazy.

Chappy
16th October 2014, 08:42 PM
Belated update

The rego expired on the GQ and I didn't have enough time to play with it until yesterday. Finally having some free time I paid the rego and tried to fix the leak. It turned out my supposed oil leak was actually a diesel leak from the diesel return line.

It's now just a case of getting the tacho working and then it's a complete functioning conversion.

I'll be taking to for it's first proper test drive to Kinglake this weekend if anyone's interested in tagging along.

Unfortunately the financial situation didn't allow for driving last weekend, plus a big Saturday night destroyed my enthusiasm anyway.

I have a mate that can recover me if it goes sour but I have trust in the TD42 that she should be alright.

We should organise a group drive up that way in the coming weeks/months.

Update

Tonight I solved a few issues that I've had from the start. I was having a charging issue, after a bit of fiddling I found out I had put the alternator earth to the charging post and left the battery charge wire unhooked.
I swapped those over and that solved my charging issue.
For some reason, fixing that turned off the battery, brake and air filter lights from my dash. Previously they were stuck on.

I also managed to get the tacho working. It was pretty simple really, just a bit fiddly.

For those that are curious:

I started by swapping the tacho component from my diesel dash into my petrol dash.

Next thing was the black plug on the back of the speedo. You can see here in this picture the yellow/black and pink/black wires. Originally the pink and black wire is just an empty, pinless slot. I pinched a pin from another plug and put it into that slot.

50528

After that it's a simple as wiring the black/yellow to the blue wire on the RPM sender and the pink/black to the green. I found a plug that matched up perfectly to keep it looking factory.

50529

Complete working dash and tacho.

This is the big one. I nosed in slowly to see what it was like. Quite deep and soft, so decided to wuss out. Didn't get any photos stuck in the middle, too busy running around with straps and things, but it was pretty funny. Good crack tho! - highmount saved the day :)

Awesome pics! I didn't realise you had tested it out... I could remember going through it a few months back and it wasn't an issue... Lucky it wasn't a TB still or I would have been skulled dragged out.

Managed to snap at the right time, came out pretty well. Should have got one of it stuck tho, never get enough photos.

Yeah I did have a little test and very nearly went for it. Did feel pretty soft tho!!

Go the diesel, they are bloody good.

What is it with you young blokes and muddy holes??? LOL I can't stand cleaning the crap out of my car any more and having the interior spread out on the front lawn....

Rossco, I thought you'd remember this feeling.....the hole at Tallarook as I remember.....

Well, I think this concludes the conversion... Tonight I wired up the manual glow button, it was the last thing left to do. All functions now work.
I'm getting mixed emotions.. I'm happy I'm finally done but sad that the conversion journey has come to an end. What am I supposed to do in my free time now???

A big thankyou to everyone on here that's helped me along the way with the conversion, you're a fantastic bunch. Now I just have to get out and drive it!

Hi mate, you'll need a TD bell housing. This will line up with the gearbox no worries. Petrol one is different.

Hi just a quick note , i'm in brisbane and will be selling a tb42 with gas conversion and manual gearbox soon. I'm removing it from my 89 patrol which i bought new and had gas fitted about 8 years ago. The car has done total of 20700km. the engine can be started and driven as still in car.Runs like a a clock just loves a drink.Has msd ignition new genuine fuel pump and 2 year old converter. No hard work , my wife drives it .Unfortunately she can't drive a manual anymore so in goes a turbo diesel auto. If this helps you let me know. cheers.Greg

Can i get your advise here please mate, could you let me know how you hooked up your coolant temp gauge, the TB loom disappears in to the dark void of wires for this and im left scratching my head and rubbing my chin...

Thanks

Hi Andy, there's just one wire that goes to the temp sender (just next to the thermostat housing) on both TD &TB ( unless the TB E is different, mine was a carby). I just put a new terminal on and hooked it up. Same with the oil pressure sender, there the same just hooked it up and it all worked fine. Saw on your post that you labeled everything, that's what i did, it certainly helped. . . Best of luck with it. . . .

Thanks Rossco,
I am thinking the EFI might be slightly different as the sender had two wires attached, one from what looked like the loom back to the cluster and one that disappeared into the injector loom heading for the idle circuit i think. It really threw me cos i wasn't expecting it.. So far its the only thing im not sure on, everything else is going to plan so far...

The oil pressure sender i changed over last night, it has the standard plug fitting and what looks like a rubber hose / tube, as yet i havent figured out where the hose / tube goes to as it was loose / free when i took the TB motor out, so it may have fallen off the fitting, im not sure..

Update, rubber hose is a vent line, does not connect to anything :) happy days

Hmm, maybe it's for a sensor somewhere. Probably don't need it if the Guage works all good. You could try giving Jono a pm or he might see this, his was an TBE although he went the full loom swap. I know the TDs have two wires one which goes to the glow plug timer, if you just go a manual switch for the glow you won't need it.

Yeah i am going for the manual glow system. its the best way to go when converting the TB loom...
I had another look at it all last night briefly with fresh eyes after reading your previous post and i now think from what you were saying previously that i have identified the wire in question. I was confused by another yellow plug which i now believe is a coolant temp sensor for the auto choke idle bypass circuit... I think i have identified the gauge temperature sensor wire as the red and white wire in the 6 pin square engine harness plug that runs to a single sensor on top of the block / thermostat housing. I will confirm this 100% when i remove the TB cluster and replace the taco, im sure its right, but between myself and my mate Stuart who is a pretty handy sparky, we get it..

Thanks for the info Rossco, what you said helped me nail it down... I appreciate the advise and assistance..
