Anyone know any good machining shops to do the head and the block for me. Also I won’t need to have the cylinders honed because I’m replacing the sleeves is this right

Where abouts are you mate, liners will need to be honed they don't come finished.

Ok awesome thanks I’ll make not of that

Any one who will not use liquid nigrogen to install your liners. Specify that. PRESS FIT ONLY. DON'T LET THEM TELL YOU OTHERWISE. specify it and even make them sign before commencing work.Quote:

Bloody hell will definitely make sure no liquid nitrogen and I’ll make them sign for it.

How do I know if they have used liquid nitrogen?

Don't think you could tell just have to take their word for it. There's a bloke in Clayton who is really good if that's not too far. . .

Oh cool, Google go2 engines and give Omar a call see how you go. .

Spoke to go2 motors today and they said they freeze the liners before pressing them in. Also they won’t machine the motor if I am rebuilding the motor myself bc of warranty and the blame game that can come afterwards.

Hmm, could try Duggan engineering in Reservoir if not there's a couple of places in Bayswater but can't remember names. .
Sent from my SM-G930F using Tapatalk
Liquid nitrogen is a problem due to the rate of contraction on the liner causing micro fractures thus weaking the liner
Placing the liner in the fridge or freezer prior to install is fine as the liner contracts in a much more controlled manner.
Ok that was my only real worry.
Thanks guys for clearing that up. I’m gonna be uploading some pictures of the motor soon and the whole process of pulling the old grenade out of the trol

Does anyone have any idea what socket to use for the end caps for the pistons. Can’t seem to get a good grip on one. A 15mm fits but i don’t want to risk getting stuck with a stripped nut

Got the motor and the block apart

Very good mate, did you take the head off in sequence of the manual?
Only reason I ask is that there's a specific sequence in undoing the bolts and we, I, some have not followed that before.

How's it all look, how many K's and whats the reason for rebuild? (Sorry might have missed some of it previously)
Sent from my SM-G930F using Tapatalk
All good Rossco so basically I bought the motor off a mate it’s got 400,000+kms on the motor and the reason for a rebuild was I’ve always wanted to rebuild one so why not. Also would love to be able to turn the key and know how much effort I put into the motor.

Yeah nice sure it will come up awesome and should be fun, enjoy. . .

Do you think they could save the crank shaft? Polish it out
Sent from my iPhone using Tapatalk
Yeah bugger bet your glad it's getting a rebuild now. Had the bearing spun on the journal or just buggered? Expect it's a result of low oil or lack of oil changes most likely ? ? Looks fairly substantial, machine shop will know once it's measured or might have to be ground to see how much needs to be taken off to get it good again. Not sure what over size the bearings go up to will determine the repaiability.
Sent from my SM-G930F using Tapatalk
I think that some debris or something had gotten into the motor and in the journal because they were in the right spot.
Yeah hopefully it can be repaired
Will I need o/s or u/s Conrod bearings?

Has anyone had any dealings with crankshaft rebuilders in Blackburn thinking about giving them a call but didn’t wanna waste my time. Open to all opinions.

Does anyone know the best place to source genuine Izumi or Mahle turbo pistons for the td42

SMS Diesel sell Mahle from memory. Try Engine Australia too...Quote:

It’s been a little while since my last post but work has kept me from my patrol. So now the gruelling task of pulling the old motor and trans out is upon me and I have no idea where to start. Anyone have any suggestions.
Sent from my iPhone using Tapatalk
Start with taking off the bonnet then just chip away at it. Label wiring to make it easier, if your air con is all working just unbolt the compressor and zip tie it to the chassis so you don't need to regas it. A few beers & tunes might help, enjoy . . .
Sent from my SM-G930F using Tapatalk
He'll need to remove the a/c compressor. Cant use the ZD compressor on the TD. But as Rossco has said. just start unplugging the loom. But remove it entirely, it goes into the firewall and plugs into the ECU. As you will need to send that loom off to get converted, if your going that way. I did and it was easy. It came back and just plugged in to every it was supposed to for a TD42. You might need to contact killa kustoms about your loom as you are going from auto to manual as well.Quote:

Yeah thought that might have been the case, couldn't remember what the conversion was from [emoji6] . . .

Beautiful guys sounds easy will take lots of pics and videos. I’m sure I will come across a few stubborn bolts
Sent from my iPhone using Tapatalk
Its actually much easier than you think. Just label shit as you go if you want. I didn't. And the loom I got done from Killa was just plug and pray. As I laid it out, everything just went where it was supposed to.Quote:
