Hey Guys,

  I have been adjusting my Toro 824 and I noticed that the drive wheel for the reverse gears has a lot of play in it. The only thing attaching it to the shadt is what seems to be a shear pin. I just don't feel that it should have this much play in it. I was thinking maybe the shear pin/bolt was replaced with o\ne that is too small causing the reverse drive wheel to have play.

Do you guys have any input on this?

His model has two drive disks - one for forward and another for reverse. The friction disk is inbetween.

Not sure which model you have but...

If you tip your machine up on its bucket and remove the bottom plate you will be eye level with the drive internals. The reverse plate rides on a shaft that is supported by a front and rear bearing, at least for the 824 models 38065, 38080 and 38085. It is the same shaft that supports the large forward drive pulley which the belt drives. The bearings may be worn but generally they last forever. If you go to the Toro site you can get the service manual for the above models and many more.

There's a good chance that the lock pin is worn.  Pull it out and inspect it.  If it's worn or looks too small for a proper fit, replace it.

I am noticing that the bore on the reverse drive disc is slightly larger then the shaft. This is what is causing the play. Is this normal?
