Turbo Suppliers
« on: April 02, 2018, 11:23:00 AM »
Caterpillar 3126. s/n 1WM 23933.   150-6141.   Pref. Spec. 143-8586.   Was 275/800 and was changed to 300/860 
I have a 3126 in a 1998 Peterbilt 330 Medium duty truck used to pull my 5th wheel travel trailer. The turbo is leaking engine oil past the seal on the exhaust side of the turbo.  There seems to be several turbo suppliers (BorgWarner, Garrett, Schwitzer, BWTS-USA, Honeywell) that Cat used and I would like to know how to determine which one is on my engine?  Stowers or Thompson Cat will sell a rebuilt but they did not know how to tell who made the one I have.
Should I make sure the replacement is from the same manufacturer/supplier?

It lasted 267,000 miles without problems until now and it still has the same boost as when I purchased the truck in 2003.

David, can you give your engine serial number where I can pull up your engine arrangement
number. This will get you the correct Caterpillar turbocharger for your engine. I would suggest
not buying or installing anything but a Caterpillar new or reman turbocharger for your engine.

David, looking at your post will you recheck the engine serial number 1WM 23933.
Second I would suggest in not running or very little with exhaust turbo seal leaking.
You can pump engine oil out and lose engine real fast. Last year had same problem
happen and owner decided to run engine and threw rod out side of engine block. Again
Want to make I’m working with correct information ( owner cost for repair rebuilt $ 33,000.

Thanks Dave you supplied way more info and dates then I have ever had on my engine.


I know the part from cat will fit but are they from the same supplier as my original?  How do you know who supplied the original turbo?  Like in my first post there are several suppliers for Caterpillar turbos.   
I will only purchase from Thompson cat in Cookeville,TN.

Dave

David, I would suggest using Caterpillar part dept. and go the Reman turbocharger.
It does not matter where Caterpillar gets there parts but one thing for sure you will
get the correct turbocharger for your engine built to Caterpillar spec. What this means
possible turbocharger problems down the road you will have a big dealer net work
to support a Caterpillar part Failure. Non-Cat service shops do not have a product
support net-work across the country as Caterpillar. Hope this answers all your questions.
