can someone tell me the model number of the engines are in old cat 955K track loaders?
I have been looking for a parts manual for one.

I believe the entire 955k series used the D330T engine. The US production being 115hp.

Thanks, do you know where I might find a parts manual for it?

Hello Driggars,
I note that you are asking what "CAT" engine the old "955" traxcavators used, the first model "955" traxcavator, Series "12A" used the "D315" engine, which was basically the same engine used in the 7U Series "D4" with a H.P. increase. I beleive that the next "955" 60A Series used the then new engine , the "D330" turbocharged engine.
The first ever "CAT" built Traxcavator, the model No 6 Shovel which was built on a redesigned "9U" Series "D6" tractor chassis with many major changes, this tractor the Series "10A" was followed by the "12A", then the "955".

If you can give the exact model, then the exact engine data can be given.

Sincere regards

You can get them from Cat Legendary Literature Services

The Cat stuff is excellent repro but pricey. At least check the list for the correct form number for the manual then you could also check ebay and ebay vendors.
They made a lot of different models of the 955K.

Avoid the "Jensales" repros, they are very poor copies.

The only numbers that are recognizable is a serial number on the engine, which is the same as the tractor ser#

61H1659

Clint, OM's info is correct...the 955K is powered by the D330T. As far as a parts manual is concerned the ebay advice is also good...there weren't many 61H series machines built, but a parts manual for 48H, 53H, or 31J would also be suitable as they are listed as equivalent to 61H in Cat literature.

thanks! that is just what I need, a confirmation. I to found out last night that there were not many references to the 61H series , seen lots of 60A, but I was thinking the 60A was closer to matching the 955H series.

I see some D330 manuals on ebey but no D330T's I would assume the D330 didnt have a turbo?

Clint

OK, thanks for the help so far, now I have one more question if someone can answer. I need to know the head bolt torque setting for this motor? anyone know?
