Just finished a gearbox rebuild on my 70″s Midget. The box needed new syncros, 2nd and 3rd gear. The rebuild was straight forward until all was reinstalled and road tested. It will not stay in 3rd gear. I can hold it in, but under acceleration or if the shift lever is not held it will pop out.
I can not fully engage 3rd gear. 1st, 2dn, and 4th, work ok.
All gears engaged ok on the bench test.
I know I have to pull it back out, does anyone have a suggestion on what to look for when I get the side cover back off?
I should add that the gearbox shifted (stayed in each gear) before I took it apart. The rebuild was done because regardless of gear selected it would grind. Downshifting could only be accomplished by double clutching.
When I got the box apart the syncro rings were worn out along with the 2nd and 3rd gear syncro cones.
I got the rebuild kit (bearings, gaskets, lay gear shaft, ect) along with the gears and reassembled.
Before you pull make sure all your fixed (2 bolts inside and two long bolts under) and rubber mounts are in tact. Is it popping out when you release the clutch? Engine shaking?
Generally the number one cause. Vibration and faulty mount on the tranny and or engine.
