CAT 299C TRACK tensioner help

[bsamot69]

Our 299c track tensioner is leaking grease. Figured pull it apart to install new seal, like our other equipment. This assembly has a second seal on an inner tube that is backside of a block in the tube. Does anybody have a diagram of this tensioner? Do we need to pull out the rest of assembly that sits on top of spring to replace the seal? What does that entail? Did not think this was going to be this complicated. Any insight is greatly appreciated.

If you want a parts diagram or some disassembly/assembly instructions a Serial Number would be a good start.

#1 keeps the grease in, and #2 keeps the dirt out.

Remove track.
Slide out idler assembly (heavy).
Reach in and slide out recoil assembly (#2 in below image).
