CAT 951C Traxcavator

I'm a new member located in south-central Missouri. A friend of mine showed this website to me a few years ago and I have been viewing the posts of interest ever since. I am impressed with the number of subjects discussed and the knowledgeable owners and operators who are willing to share their information.

I have a number of questions concerning the 951C I own but, I will try to limit them to a few per post.

Does anyone have, or know where to purchase, service manuals for both the machine and engine?

The machine serial number is 86J3055.

The engine:
model number - 3304
serial number - 78P5767
arrangement number - 2P6779

(I do not know the significance of the arrangement number.)

Thanks for your help.

Some guys on here have places where the books are obtainable. As for the numbers on the engine in your case the 3304 is the engine model number & in later years Cat used a separate serial number from the machine where in earlier years they were the same as the tractor S.N. The arraignment number is parts, (items) changes installed on the engine to make it compatable with the machine it powers over & above what a standard engine would have on it.

John, if you're patient you can usually pick up any manual on ebay for a good price. I've just done a quick ebay search and there doesn't seem to be any listed at the moment for your machine though.

SJ,
Thanks for explaining the arrangement number. Is there a source for deciphering what the numbers signify? I have looked at Caterpillar's site for manuals on older machines but, they list only the parts books for the machine and engine. I already have a parts book for the machine. I'll have to keep looking.

rusted,
I've heard people suggest Ebay. I'll give it a try.

On another subject, I need to replace the sprockets on the machine. This machine does not have the segmented, bolt-on type. The sprockets are solid and the worn rim has to be cut off and a new rim welded in place. I plan to have a local welder work the sprockets but, I would like to know as much as reasonable about the process before I start. Has anyone discussed this procedure on a previous post and/or do you know if this would be explained in the service manual?

Usually the Cat parts books for a particular tractor lists attachments & arraignments in it but probably the bill of material that came with a new tractor listed the above normal parts, changes & added componants etc.that was part of the new tractor.

years ago I converted a 955 to bolt on segments using a weld on hub rim.
At that time there was a hub ring availble as well as sproket rims. then you only have to go thru the welding procdure once.

I don't recall either sprocket segment adapters or plain sprocket weld on rings ever being discussed using Cat recommended procedures on this BB. If you can get it there is a Cat published form #FM036159-05 (dated 1/71) describing the process. I have one and it is about twelve pages long with tables and illustrations (back when everything was published in four different languages). Problem is it is a crappy zerox copy that does not scan well enough to be legible. The application data precedes your model and at that time a adapter ring was not available for the 951B but I'm relatively sure one was provided later. Check the attachment section of your parts manual, might be listed there.

PS: Never have seen sprocket rim (weld on) procedure described in service manuals.

Never seen any model of the 951s with segment sprockets,the sprockets were rerimmed and hundreds were done at my place,the sprocket for the 951 did not have a hunting tooth and you had to jump a tooth to get the bush to run in the unused ones when the other wore away,a competent welder will have no problem welding on a couple of rims in situ as it is a standard procedure in the machinery maintenance/repair business. The 951B/C liked to have the radiator kept clean so the cooling would not be impaired,Good luck with your investment.

Hi Team,
here is what I have on this subject from the Undercarriage Conversion Guide 1991 Edition PEGP2806 Rev 04.
Next posts will have the data I have from Conservation Bulletins 1951 on rerimming sprockets and building up sprocket teeth.
