When I try to shift to 2nd speed, I have to push very hard on the gear shift lever.

What can cause this?

Thank you

I am also having problem shifting. I disassembled the transmission and reassembled. I believe my adjusments are alright. Question: are parts for the 31, 32 transmissions still available...synchromesh parts in particular.

Clutch adjustment can be one cause. If the clutch does not fully release it will shift hard. Does it shift ok when stationary?? Grind when going into second??

The 1931 was a completly different non- syncro trans.
Try double clutching when down shifting to 2nd. If that helps then you know the problem is in the syncro. part of the transmission.

Does not shift well even when stationary. Double shifting doesn't work either. Jim

I would check for wear in the end of the clutch fork and the clutch actuating plate, as the hole in the plate can become oval, and you may be losing the travel to release the clutch plate. Always a good idea to check the easy things first before taking the gearbox out.

I had a problem with my 33 (basically the same transmission) and discovered that the retaining cap that holds the shift lever down was loose. Several turns and I was back in business.

You should be able to determine if it is a clutch drag problem or not by shifting it into a non-synchro gear ( ie first or rev.)

If it shifts easily into 1st and rev without any gear noise I would rule out any clutch drag problem for now.

As others stated, it don`t seem to be a clutch problem because it's easy to shift in first and in rev. And yes it's hard to shift in 2nd even when stationnary. I don't hear any grind noise, it's just pretty hard to push the lever in place.

First thing I would check is the slider in the top of the transmission cover to make sure it slides easily. There are two of them one for first-reverse and another for second-third. They are attached to the shifting forks which actually move the gears into place.

I already verified this, both are working correctly

If the shift rails and forks work ok when stationary and the clutch is releasing then chances are the problem is in the lever and tower. I would remove the shift lever assy and inspect it.

Is the die-cast retainer on the top of the transmission cracked or broken? Or interlock worn on one side more than the other? Do both yokes fit the same on the shafts? If there is wear on the shafts or in the yokes then the yoke may tilt and bind on the shaft.

You can also try shifting the gears with the transmission top removed to observe the movement of gears. Also move the shift lever with the top removed from the transmission to see if there is any binding on that part. Once you isolate the problem then it can be fixed.

I verified all of this with no luck.

The problem seem to come from inside of the transmission.

The, according to the manual "second and third speed clutch" seem to have problem sliding. May the rear synchronizing drum spring can be the cause?

If it is in the transmission, then it must be the shaft/slider fit. What happens when you manually slide the second/third slider? I should move freely by hand and even by gravity if you tip the transmission case. If it doesn't move easily then you will need to remove the shaft and gears to determine the problem. That is unless by moving the slider you discover a "hard" spot or some small metal contamination between gears and shaft that can be removed.
