I ran a K for a couple years with another operator at the local dump the only thing I could think of was that he rode the brakes all the time cause I worked with one of the Cat mechinics from Wallace Machinery put brakes 9 in it twice, the owner finally had Cat disconect the dual system and I don't remember Frenchy telling me it neded any different parts, but this was an early machine 77V1855 was the serial on it.

Thanks Guys, that is helpfull.

I will looking further at this as soon as the tracks are complet. Putting a new set of chains on.
