I am brand new to heavy equipment. I have a CAT 955L s/n 85J7605. I am wanting to change the engine oil. Where is the drain located?

Ciao nella parte anteriore in basso. C'è una piastra con bulloni, lasciala cadere e sotto troverai un tappo dell'olio.

There is a cover plate on the belly pan that needs to be removed to get at the drain plug. Just make sure you see the oil pan. I believe it's the furthest forward cover plate. One further back is for the transmission I believe.

I don't know just how yours is, but they can be heavy. I have one on a hinges and if you go to far it drops. I have a 4 bolter that I put a longer bolt in one corner then just swing it to the side.
Best of Luck

Like Bluox said look for a hole on the side use a long extension and a 9/16 socket you can get to it from up top if side panels are removed and bucket is up should be on the left side

G..G..G..Granville.........!! Fetch your cloth.
I am brand new to heavy equipment. I have a CAT 955L s/n 85J7605.
Might I suggest that an Operation & Maintenance Manual would be a good investment.?
It appears that for your specific machine Serial Number two manuals are required.
SEBU6250 covers maintenance and can be downloaded from Cat Publications for $28.
SEBU5511 covers controls & operation and is the same price - $28.

Attached the parts manual listing for the crankccase guard for your machine. It may be of some help to you.

Mine is a 85J (3304 engine) and there is a plug out the side of the pan. I get to it from the side, think its from the right side

Doesn't pour straight out, get a bit messy but works.

Sounds like the access to the drain plug may have changed over the years. My former neighbor had a later 955K and it had a plate on the bottom of the skid plate to remove. Thought the 955L would have been similar.

Is there suppose to be a pipe plug on the bottom of the valve?
