Hey guys, My CASE TR320 has blown a drive motor hydraulic supply line. The drive motor has to be removed for the repair. At least it's on the same side as the "leaker", so I'll replace the drive motor at the same time. The former owner obviously used this machine quite a bit pushing with the front of the tracks off the ground. The rear idlers have worn pretty wavy and deformed where they contact the tracks. I planned on leaving the idlers alone until I replaced the tracks later this summer, but since I'll have the one track off anyway should I replace the one idler now?
