Today as I was backing the bus into a parking place, the clutch pedal suddenly became unusually light. It did not stall as I slowed down, so the clutch wasn’t stuck engaged – however once pulled out of gear it would not go back in while running, meaning the clutch was at least partially engaged.
I’ve always thought of the engine/transmission that are in the bus as temporary – I didn’t do much to these other than disassemble, clean, and reassemble. As such, there have been one or two roadside repairs needed, but I’ve always been able to MacGyver it well enough to avoid a tow. That wasn’t the case this time and I had to have it towed a few miles back home.
It’s not a problem with anything I can see on the outside (pedal/cable/fork), so instead something has occurred somewhere inside the transmission. I didn’t hear any pops or bangs, so likely it’s something along the lines of a bent clutch fork. I’ll pull the engine/trans over winter to both find out the problem and also rebuild for more speed, less noise, etc.
