What is the key number on the diagram for the seal you're looking for along with the Cat part number on the next page that lists all the parts? I thought these were standard o-rings.

Look at the two pages I attached which I think is what you need. Are you talking about key number 2 with pn 4J0520?

Also, what TM are you using? The full TM? Or an online version?

The #2 (4J0520) is standard O rings on the exterior of the swivel where the hoses connect.

#19 is the swivel assembly. There doesn't seem to be any info on the interior parts. I have the local Cat dealer searching for info but they have not come up with an answer yet.

I have the full TM off-line.

Got it. I didn't realize #19 was servicable with parts. Hopefully someone here has more info for you.

I suppose it was not intended to be, but can be disassembled and there are internal seals. It would seem that somebody somewhere has cracked this nut before.

I am in search of seals for the 5R1377 swivel assemblies. The part is discontinued by Cat and I can’t find any info on the internal seals. See attached photos

any thoughts would be appreciated.
Just for future reference, Cat corporate was no help, but my local rep chased the part down at a hydraulic shop. It is a TP-024, available online or at a quality hydraulic shop.
