avgwarhawk Posted March 27, 2021 Share Posted March 27, 2021 (edited) One project on my bench I have been trying to get to.... Sliding 1st/reverse gear pitted. Noisy as a cement mixer. I finally had a minute to crack it open. Fortunately I have been able to source two sliding gears (I have two manual transmissions. One in the car. The other right here on the bench). I also scored a cluster gear for future use. All other gears look good but need closer inspection.

avgwarhawk Posted March 28, 2021 Author Share Posted March 28, 2021 I have assembled the gears and mechanisms to move the gears however I have come across an issue. As I spin the shaft assembly, any gear, the entire input and main shafts expand forceful pushing the input shaft bearing out. I can not push the bearing back into the case. If I spin the assembly in a reverse direction after it sound out the bearing it will retract the bearing(or pressure released) so I can push it back into the case. See the video.

avgwarhawk Posted March 28, 2021 Author Share Posted March 28, 2021 Problem resolved. The sliding sleeve gear was not playing nice with a thrust washer between the input shaft and main shaft. Small series 3 speed is rebuilt. 1 Link to comment Share on other sites More sharing options...

Let me rephrase this: The cut of the gears is causing the end thrust of the assembly, something has to hold the assembly in the case. I will look in the manual.

The ball bearing, which is shielded on rearward side, is pressed against a shoulder on main drive gear and held in place by an oil slinger, washer, and retainer (snap ring) . The outer race of the bearing is grooved for a snap ring which fits between transmission case and flywheel housing to hold bearing and main drive gear in place."

The issue was a thrust bearing in front of the sleeve gear. It's now working as designed. 1 Link to comment Share on other sites More sharing options...

I will look in the manual. John I concur but the expansion of the input and main shaft would occur no matter if the shafts spun clockwise or counterclockwise. I ruled out the cut of the gears as the cause. I found a thrust bearing in front of the sleeve gear as the culprit. Link to comment Share on other sites More sharing options...

I re-read the entire thread and realized you had answered my first question 3 hrs later with 2 videos, somehow I had completely missed that. Carry on! Pay no attention to that man behind the curtain!

No worries. A helpful hand is better than no helping hands at all. You stating the gear design does force the parts forward with the spin of the shaft. I thought so as well and your answer confirmed it. So I needed to rethink what part was installed that may be the culprit being pushed forward with the shafts. Thanks for the help! 2 Link to comment Share on other sites More sharing options...
