GU 42TDi 12mm pump upgrade

[0-TJ-0]

Afternoon ladies and gents. Plenty of good information on here for me to traul through as always.

I've just ordered a 230hp 12mm fuel pump from UFI over in WA and some other bits and pieces including a planned front mount upgrade for the intercooler.

Thought I'd put the shout out and see if anyone has any advice before I start pulling bits off. Any tips and tricks particularly on removing/replacing the pump would be appreciated.

Also if anyone wants to see anything in particular from my upgrade while I'm doing it I'd be happy to follow up on here.

Cheers

Just me but I'd be getting a mechanic with a Dyno to do it , that way you can get it tuned right .

Have a look at this thread from post 418 for my Front amount and UFI pump fit.

Thanks fellas. I was always going to take it to someone who knows what they're doing to give it a decent tune. Don't see the point in paying someone to swap out a pump.

I've had a bit of a look at your post MR and looks like there's a lot of info in there. I'll be referencing that for sure once I start pulling bits off and trying to fit my intercooler. Looks like I've got the same one as you only half the size.. I've also only gone 2.5in on the IC side of the plumbing as I was a bit worried about getting it through and around where I wanted it. Hopefully won't restrict things too much.

The parts are slowly starting to arrive! :)

Got a bit done today.. looks like I've got all the hard parts ahead of me.

Thanks again to MR. I reckon you've saved me a lot of headaches when I eventually fit a winch!

For anyone interested..

Technically you are doing nothing wrong, your first two post where reply's 2 Darren's post which contained a link therefor they went into moderation, any posts made by members that have not made 15 posts will get moderated if they contain links 2 websites or email addresses ( even if its in a quoted post ), unfortunately doing so helps us keep some control on spammers.

All plumbed up now except for a few bits i was missing. There's a lot of joins which I'm not super happy about but should be right to get me up and running.

Bit of a hold up on my pump and turbo from ufi but should be here early next week. :thumbup:

Looking good mate. Glad my thread has been helpful.

Just an observation, why have you not fitted clamps to the intercooler piping?? They will blow off for sure!

They're on thier way! I had the presence of mind to pre-order the silicon adapters for the intercooler but totally forgot about the clamps to suit! Not a biggy, I ended up needing one more bit of pipe anyway.

In your thread I read someone warning you about the joiners blowing off. Have you had any issues with this? I have one or two joins where I had to cut the pipe (and the rolled bead off) to make it work. I'm thinking I'll need to at least sort those couple joins out with something. In the long run I'd like to take it to someone and have some parts made up in stainless but if I have no issues that'll probably never happen...

Hi mate, yeah i bought a Pipe and Joiner package off ebay including the good clamps. I still needed a few extras but it saved me a packet..

i cut most of teh pipes to suit my specific needs and cut most of the rolled edges off as they just didnt work. I made a point of keeping everything clean and no WD40 or other contaminants. some of the dry joints where hard to get on but got everything sorted.

When i pumped 25psi+ down them i blow a few f them actually. only where i had used crap clamps though. anything wth the double pull clamps held well. I also used a impact driver with a deep 10mm socket to do the clamps up. Saves a heap of time and worked great. The silicon and decent clamps will be fine i reckon. Holding 27psi to 32psi in 40c all day now mate.

Very similar to the kit I got. The clamps look good and like you I was carefull to keep all the joins free of lube.. as painful as that was in some parts. I've been doing them up with the impact drive too, hours worth of of bolting and unbolting there otherwise.. well I might leave them be with that advice then. Just make sure they're all nice and tight.

Braved the Adelaide heat today to get the power steering cooler mounted. Might not be ideal but I'm pretty happy with it's new spot.

Got the new airbox in tonight...

[0-TJ-0]

Got a few bits and bobs in the mail today..

77787

And managed to find 5 minutes to get the turbo bolted up..

77788

Getting pretty excited to get it all together now. On a side note I have a slightly used denco/borgwarner turbo kit up for grabs if anyone was interested? Not as nice as the new unit but still feels solid and would be a nice cheap upgrade for someone.

Got the turbo side of things pretty well finished tonight and started pulling off all the bits to get to the fuel pump.

I got the gear off with my state of the art gear puller..

And now I'm about at the point where I unbolt the pump itself but I have a question before I do.

I assume it's just me but I'm having some issues finding my way around the electronic service manual.. what I was wondering is if anyone knows about how to orient the pump when you put it back on/replace it? I noticed it has slotted holes for fine adjustment of the timing, is this something I can get close or is this for the guys with the dyno to sort out? I have all the timing marks at tdc ready to go back together I just don't know how to set the pump body.

[0-TJ-0]

So I finally got it all bolted together this arvo and took it for a quick test drive. Everything seems okay but I think the timing is still way out and I can't seem to get it even close to where it needs to be. Rattles like a mfkr under acceleration. runs sweet at idle though. Time to borrow a trailer and get it to someone who actually knows what they're doing to finish off I think.

Awesome. Did you use a timing tool to set the timing?

Nah, I just left it set at where the old pump was. I tried a couple mm each way off the old mark but didn't seem to make much of a difference and I was really just prodding around in the dark. I can't really justify buying the tool when I can probably pay less just to get the mechanic to dial it in as it goes on the dyno.. plus I have access to a car trailer thankfully.

[0-TJ-0]

Got it all up and running but as expected I need a heavier clutch. I can't seem to get a straight answer to make a decision. At the moment I'm looking at a terrain tamer fortified (tttk7235f) do I need to go this heavy? They say they're good for nearly 800nm, the next step down is thier HP model at 565nm.

The pump I fitted is sold as a 250hp unit but I expect to fall a bit short of that. I assume that I'm looking for something that can handle the 600nmish tourqe range.

I'd prefer the lightest viable pedal feel to keep the misso happy when she needs to get in and drive it.

Settled on a Terrain Tamer HP clutch.. I was tossing up between that and the Exedy Safari Tuff clutch. Never realised they were the same thing until I opened the box :1087:

Yep. Looks like a clutch.

TT/safari will be fine for your power mate and still ok for the mrs no problem at all.

After a day and a half I got the clutch in and sorted. Not a job I'd be keen to do again in a hurry! The box fought me the whole way..

Finally been able to get in and have a good drive and it's a totally different truck.. should have spent the money years ago.

Couple bits and pieces left to do, get the boost right, some new gauges, decide on an air box.. final tune and then her maiden trip back up to Coober for a flying visit.

[0-TJ-0]

So I got some Autotechnica gauges delivered today and I think I was expecting a bit better quality for the price. I wasn't expecting VDO but maybe at least a glass face and metal pods?

They're comparable to the cheapies I have in it that I got for 60something dollars for the pair. Anyway, they're what I've got now.

Anyone following my comments on other threads will know I've been chasing a squeal noise coming from near the turbo. My symptoms were a loss of boost and the squeal coming from near the turbo that would disappear when the exhaust temp got to about 350deg.

This all seemed consistent with an exhaust leak to which I found a decent one where the turbo bolts up to the manifold. Spent last week fixing that, put it all back together and it was fixed!.. or apparently not. After a bit of a drive around the noise started to come back until it's as bad as it used to be.

So exhaust leaks are fixed.. It's either the intercooler/piping or the brand new turbo is broke. I had already checked every joint in the piping but not at pressure.

Went to bunnings and made up a quick bung for the intake side of the turbo and fed it a bit of air.

78611

Cracked the tap until the air started to flow and bingo.. couple of squeals pipe up around ic pipe joins near the turbo.

Test and adjust some clamps and that should finally solve my problem in the short term. Long term looking at getting some sections made from stainless with fewer silicon joins to worry about.

Happy man. Been chasing this noise for ages.

Looking good. what did you do with your Denco? AB is this a turbo that would work on your Ute?

It would have for sure. Had a chat with AB a little while back and it ended up not being what he was after? It's gone now anyhow sorry mate!
