My good friend and neighbor needs to replace the turbo on his 300 horse 3208 caterpillar , the motor is in an 89 Grandvilla
The mechanic that reinstalled his rebuild injection pump assured us that we could find an excellent after market turbo for much les than a CAT genuine unit.
Has anyone here bought aftermarket parts for big rig motors anywhere with success?
Any feedback is greatly appreciated!
What is the part number on the original turbo?
I'll find out tomorrow
Tom,
You could just have the old one rebuilt. If it hasn't spun the outer race of the bearings in the case you should be able to fix it with little effort.

I would sure look at a factory reman (i.e. Caterpillar) as a viable alternative to either new or "made to replace" turbo.
Not sure but check if Cat has a cartridge for that engine,it is the turbo minus the intake and exhaust housings,which should still be good.For that engine I would not consider an aftermarket,Cat parts are pretty good,expensive but good.
Let us know what's wrong with the old turbo.
Ditto on checking with CAT, I blew a turbo on the AS, smokin' like crazy, especially in the high, cold country, where it was pure white smoke. Got a re-man, it STILL SMOKED! Went to the dark side and pulled the head, pump, injectors, etc., everything checked out fine. Turned out the re-man had sat on the self too long and the seals had dried out. They replaced the turbo n/c, but I ate the labor. The only plus was I had a fresh top end!
The original part number is 7c3856
Cat is both time and cost prohibitive.
Rebuild is $2400.0 and two months out.
Keep checking Ebay and Nationwide craigslist,might get lucky,what exactly is the problem with his turbo?
Why not just buy a used one? They are not expensive and if treated right, turbos usually last a very long time. Several here including a new one for about $400 but check model number.

They rebuild pretty easy. Look at U tube and use a "T " style wrench the remove the shaft nut so as not to bend the shaft. The nut is also red locktited and should need a flame to loosen.
I may have a core as I rebuilt (mostly Garret) turbos in a prior business. I was the Turbo warranty builder for Merkur, Peugeot, and some Dodge dealers in Rochester NY for a few years.
I bought all of the diesel cores as they hardly ever scored the housings. FWIW you can bore the housing over size and turn the shafts undersize on the auto sized units and i would assume the big body s also.
I send all of the noisy rotating units out to get balanced. Noise/Whine is a sign of out of range balance . Mercedes has the highest /finest balance specs and the hot sections fit most of the autos with Garrets.
I have at least one Truck cores and the pieces are not expensive . I expected to rebuild mine in the next year or so but it uses no oil and runs at a normal noise level .
I have all of the tools other than the balancer as far as I know. If there is interest , I can rebuild the one or two that I have in stock. Typical price is about 600$ if the housing and shaft/wheels can be used.
Crusty oil/ coking, drags the sealing piston ring and starts it turning in the housing, allowing oil to pass is the normal failure. .
You might check with these guys http://www.midwestdiesel.com/PartTypeDetail.aspx?partype=Turbo&engtype=3208 . They seem to have a lot of CAT engines and parts that they advertise as surplus.
I've not used them, but have kept them bookmarked just in case (both MH's I've had were/are CAT powered).
I just looked at that site, they have most stuff (including turbo) for my 3116 CAT. Will bookmark, thanks! ^.^d
