Re: Stuck Gear

Didn't find any recent emails from you but who knows what part of the universe those things wind up in from time to time.

On the failure to move into a gear, the first thing I would suggest is follow the procedure in this thread on the transmission not wanting to go into any gear to verify the levers at the base of the steering column are free and will easily and independently rotate on the shaft. I cannot stress the number of issues the lack of lube to the upper 2-3 lever has caused with shifting. If one of the levers is dry or sticking, the mechanism is trying to shift the transmission into two gears at once. If the transmission interlock is working at all, the least amount of movement of one arm at the trans will almost immediately lock the other one out. Since both are trying to be moved by the column levers the result is no movement for either. With your issues with the other gears, checking the levers is definitely something I would look into soon.

As to the grinding gears, I would check the clutch free play particularly if a rebuilt clutch disc that might have been a tad thicker than the old one was installed. The step of checking or adjusting the free play might not have been done when the disc was replaced. Also look for anything worn, loose, or bent in the linkage that would prevent full travel of the fork and throwout bearing. Grinding could be caused by the pressure plate not releasing fully, a rusted input shaft keeping the clutch disc kind of locked so it cannot move and stop touching the flywheel when the pressure plate releases, or even too thin a lube in the trans not putting enough drag on the gears.

If the levers prove to be OK, the issue could be inside the trans/OD unit. R9s have a spring loaded lockout collar which moves to lock the OD planetary gears together into a solid unit when the OD is locked out or when driver wants to go into reverse. Gummy oil, a weak spring, or something bent or otherwise damaged can prevent the collar from moving fully. The collar slides a pin which is supposed to keep the transmission from going into reverse when OD is engaged. If the pin does not fully move that will keep the trans from going into reverse. An issue with the OD electrical circuit keeping the solenoid engaged when it should not be is also an issue that could prevent the collar and pin from moving properly. A stuck interlock pin will not affect going into first gear though but a sticking lever would.
