Tool Bar Dozer for D2-5U

we're visual here, please post photos. i rebuilt my tb cylinders 2 years back. i disassembled only one, measured up parts needed and bought parts aftermarket from hercules hydraulics for both. good luck

IIRC, the tool bar for the D2 was a #42 tool bar. One source for a parts manual is here: http://www.repromanuals.com/search.php?mode=search&page=1. Another is here:http://www.ytmag.com/contents/caterpillar_manuals_list.htm. Good luck in your search.

It's possible you rolled or pinched the o-ring on the head as you pushed it back into the cylinder past the snap ring groove. It's easy to do. Sometimes there's a burr on the snapring groove that needs smoothing down with fine sand paper (and clean all dust away!) before you push the head back in. Also helps to lubricate the whole area with oil or even grease and take your time.

On the other hand, it appears that you could remove the block on the other end of the pipe a lot easier than messing with the head end of the cylinder. OK, looking closer, I guess not........that part is cast on the end of the cylinder, it's just the adapter to the flat face o-rings that is bolted on.

Have you tightened the bolts/plate that hold the head firmly against the snap ring? If not, the head will move slightly as the rod goes in and out and the packing will leak from that motion. Can also drag the head into the cylinder enough to completely blow the packing if it gets in a bind as the rod is retracted.

i got the breakdown of that cylinder here some where, i'll try to post it tomorrow.

Didja' find it yet??:hat:

hope this works, i have trouble with scanners. this is the only cylinder with a nut on the return tube. hope this helps, it really don't open it up much. if u go to cat, you'll have to buy the kit at 70.00 iffen i remember. ( no individual parts) that is the 1h813 cylinder same as i rebuilt. there kinda a pain to get apart iffen i remember. good luck.

YES!!! Thank you Mike! The parts drawing also gives me a clue as to where to start looking for a parts book of my own for that toolbar.
Does your parts book say which of those tool bar numbers apply to the D2?
The numbers I'm talking about are:
NO. 42, NO. 64, NO.2, & NO.64

That sketch you sent is exactly the ram I've got.

Thanks again!!👋
