Hello all,
I've got an odd one. My faithful shay has started running oddly since I replaced its traction tires. I'm not sure if its because of suddenly found new traction, or just age, but the drive-shaft seems to slipping off itself. See below:
The green arrow is the spot where the gear on the shaft connects to the motor gearbox. It is solid as a rock and isn't slipping around.
The red arrows however, is where I've been able to determine where the problem is. When running forward, the drive-shaft seems to slip out of the hole in the crank-shaft (I'm not sure what this stuff is all called tbh) located where the left arrow is. When running in reverse, the same problem occurs where the right arrow is.
At present the engine runs better in reverse than it does forward.
MTH offers the entire cylinder assembly with the shaft as a replacement part, but I was curious if anyone had any solutions on how to fix this.
