Hi All,
I have an issue where the car won't move from a stopped/idle position. I tried to warm it up to temp, slowly open the throttle, punch it, etc. The car just won't move.
At low RPMs, I can see the clutch shoe move forward and connect with the clutch bell. This causes the pinion gears to spin counter-clockwise which in turn spins the spur gears clockwise (when looking at the car from the right side). When this happens, the car is suppose to move but it does not. It seems like the one-way bearing on the 49t spur gear is slipping.
When I let off the throttle, the spur gear and pinion gears are still spinning. As it winds down to almost where it is going to stop, the car jerks forward 1/4 of an inch. It seems like at that point is when the one-way bearing locks on to the shaft.
The above makes me think the one-way bearing is slipping.
I checked the following: 1. i turned off the engine. Put the car on a pit stand so the wheels are off the ground. I moved the large 49t spur gear (with the one-way bearing) clockwise. This causes the wheels to spin like it should.
2. Then i took the car off the pit stand and manually moved the car forward. The spur gear turns clockwise like it should. If I hold the spur gear, the car won't move forward.
The above makes me think the one way bearing is working.
But as stated above, when I start the engine and hit the throttle, the pinion and spur gears move but the car stays still.
Also, this problem did not just happen. There has been something wrong for the last few times I ran it. For the first time it happened, I ran the car for 20-30 minutes. All was fine until I slowed the car down until it stopped and then tried to open the throttle half way to get the car moving again. At which time, the car won't move from a start position. I had to slowly open the throttle before the car would move. After the car moved, the car was fine. I could hit the brake, make a turn, and throttle out of a turn without any issues. The only issue was moving the car from a stopped position. This problem continued for the next few times i ran it and the problem just progressively got worst. I thought it was the clutch shoe or the clutch gap and end play, so I put in a new yellow shoe and re-checked the gaps. The problem just got worse. Now, the car won't even move when slowly opening the throttle.
FYI: I did not put any one-way lube on this gear when I built the car. Do you think I damaged the bearing as a result?
