D5G, RKG01078. Hello group, I'm learning my machine and need some advice on the track system, in particular the Idlers.
Both of my idlers have lateral and one with vertical play so my questions are: 1. What are the tolerances for movement both vertically and laterally? Obviously mine are excessive but I don't see anything in manual,RENR74852 that even discusses the undercarriage in detail. In fact, I'm looking for SEBF 8599 (Undercarriage Recondition Guide) if anyone can send me a copy. I don't know if this has that info but I'm not sure what Bulletin to ask for.
Are the inside of these bearing plates (part of the Idler group, 444-5732) supposed to seat against the frame rails and then shim the outside plates (6S-7220) so that chains ride evenly on the idler? I think the shims (6S-3286) are meant to allow the yoke and Idler to move further outboard correct? If you look at my left track, I actually had to weld a 1/4" plate on the outside plate so that the chain rides evenly.
Is my vertical play a result of the bearing plate being worn? Should I weld a strip on it or replace the entire group?
I have some frame rail repair to do as well, you can see the white clay in the damaged area for reference.
I may be answering my own question as I type this, but I'm going to take the tracks off and the idlers to inspect those bearing plates. Pic 1 is the Idler Group Assembly, 2 is my right frame rail and the bearing plate on the inboard side. Pic 3 is the field repair I had to do. Thank you in advance for the groups help.
