Offroad-Express

After skimming manifold, new studs made, cleaning all bits etc ready for fitting. Had another look at turbo, this time noticed quite a bit of radial clearance on compressor end, not quite rubbing but close, dont know how I missed on initial inspection
No problem will get overhaul kit with bushes and be good as new
But while checking out 12 point torx head on turbine end of shaft noted two flats had been ground on this, probably by someone previously attempting to dismantle without correct tools.
Thinking this will definately cause out of balance and premature wear of bearings as only 40,000km on unit apparantly. As not equipped to balance myself looking for turbo rebuilder to do for me, anyone recomended by forum members would be good.
Turbo is Schwitzer S2 to be fitted to TD42. CHEERS Oh yeh someone in Auckland prefered.

I'm in the same boat as well, I'm not sure if my turbo needs a rebuild but I'm getting a new bigger compressor wheel soon so the turbo needs to come apart and may as well be rebuilt.

I've been told to try Alltech http://www.turbo.co.nz/alltech/index.php

Anyone had any experiences with them?

Cheers Andrew, actually phoned Alltech initially when looking for turbo, they were 5k all up for DTS kit,I can still afford rebuild, fit myself and still be up 2k so not all bad, and piece of mind it is almost good as new. Still kicking myself for not picking it up.

There is also Diesel & Turbo in Penrose, sure I can do yellow pages and google thing, but interested to hear of any experiences, recomendation and prices from fellow forumites. May be someone on here in the business also.

Hope your rebuild/upgrade goes well.

Alltech have just rebuild the exact same turbo for me, hoping to pick up today, cost $670. Will know exactly what they have done when I get the receipt. Mine blew the seals due to the crap oil return set up(done when I bought truck). First thing I'll do after refitting is drain turbo to sump rather than alternator oil return

Going in for glow plugs and injectors on Wed. Seem like a good bunch to deal with but the proof will be in the pudding I guess.

I'll let ya know.

Hi Mudtroll,Ah thats interesting to know about oil return to sump, seen some info on here about that, I queried denco who supply kit and they still recomended oil to left side of block ok due to top mount, after seeing your experience will definately go to sump now. If you cant trust supplier who can you. So that hasnt probably helped mine as thats how it was on previous safari it came off. Just out of interest how much radial clearance did your turbo have, mine roughly about 0.4mm, also do you have any sign of metal removed from turbine end bolt due to possible balancing,thanks

As others have said, go to Altech.

I didn't look at it that closely,was never gonna fix it myself. Alltech stressed the importance of sorting out the oil return,particualy if using it offroad as truck can get on all sorts of wierd angles, like stuck halfway up a steep bank, as it is presently the oil would just about be trying to drain upwards. I have got the correct placement for oil return details somewhere,let me know if you want them.

not sure if its the same specs and mounting etc but a mate went to nissan and bought some t3/4 hybrid chinese replica thang to mount on his safari he's turbo'in for $380ish new.. thought that wasnt a bad price for one..

Thought about that & buying secondhand turbo off tm but thought I'd rather spend a little bit more & get a fully rebuilt good qualitly turbo than a chinese one made out of old tin cans. Mate has already wrecked one of those.

Thanks niblik, got the same thoughts as Mudtroll on that one.

Hey guys just want to know if how you got on with Alltech?

"But while checking out 12 point torx head on turbine end of shaft noted two flats had been ground on this, probably by someone previously attempting to dismantle without correct tools. "

From memory a lot of turbos have two flats machined on the torx nut. could be wrong tho but it does ring a bell( but well machined not ground with grinder or something)

hi we deal with alltech all the time, they are a top bunch, they rebuilt my CT26 with new internals etc etc very cool, great workmanship and resonably priced

All sweet for me. They even did a pressure test for 45 mins on the water system and not a drop of water in the cylinders so thats good. good price and prompt work.

yes you are correct. I think its done during balancing but could be wrong. Every turbo I've owned has had some kinda machining done to the nut.

Yes that was correct guys, they were balancing marks.
Yeh but me being clever thought I would dismantle turbo myself, done a few but not this tiny.
Whilst polishing back face of compressor wheel , the basta d grabbed and bounced off workshop wall, note a ships workshop wall is a steel bulkhead. ouch
One slightly bent turbo shaft and chipped compressor wheel
Cost of new compressor wheel. $220
Called on a friend and had threaded end of turbo shaft straightened to within microns, if any . But adviced by turbo guys there is risk of any shaft been straigtened snapping on you, so will not be using.
Cost of tubine and shaft $750
Plus the turbine housing not in good shape. So repair about 2k, new Scwitzer s2 about $2700. So lesson learnt, makes a new kit seem cheap aye. Shite happens.
So sitting tight weighing up options , staying with original turbo easy for fitting to existing kit, not often for sale . Or have option on Garret turbo set up with slightly more mid range boost, good for towing.
T3 flange the same, will have to make dump pipe with flange type versus existing sliding spigot on schwitzer/cast dump pipe set up . The garret can be made 3" where as the former 21/2". So a bit of searching to do.

Oh dear! looks like I got off cheaply when I got alltech to reco mine.

bit of a bugger about the accident, I used to do all my own turbos when I worked at Trans diesel, only thing I outsourced was sending the turbine/shaft with compressor and nut off for balancing. but the smaller you get the harder it is to get those little bugger cir-clips out.
what sort of ship are you engineering on?

I'd be spending the money saved by going with a Garret to fit it. You should be able to get BB turbo for under $2k and that will be better down low and give more up top if you spec it right.

Tell me about it
The big circlip on compressor housing
Those little ones retaining bearing pack Didnt even have circip pliers small enough, no problem didnt get that far anyhow.

Engineer on Golden Bay cement ship.
We use Trans Diesels to supply most of our filters onboard, good for safari ones too.
