B112 shifting

Recommended Posts

My B112 has been grinding when I go to change gears the last few weeks. I broke the clutch rod while plowing snow and replaced it with a spare I had. Today I adjusted the belt guides according to the manual. My question is when I brake/clutch the drive belt stops, the tractor stops, but the drive pulley off the rear end still spins. Should it be like this? And if so what else can I check/adjust to get rid of the grinding while changing gears.

Also it doesn't do it every time it's actually worse the more of a complete stop I come to.

"The grind" usually happens when you let off the pedal in neutral and the trans input pulley is spinning.

The clutch belt needs to have just enough drag on it to stop the pulley from spinning when clutch is depressed, before shifting into a gear.

I think most have a belt guide on the clutch idler that stops the belt when depressed and then the belt should stop the trans input pulley from spinning.

Hope that helps...good luck sm01

I guess I missed something here? If the belt is stopped, and the tractor is stopped, there is no way the input pulley can be turning, unless the transmission is in neutral, then it will only freewheel for a second.

If the tractor is in gear, and the tractor is stopped, the input pulley can't spin, it is connected by gears to the wheels.

If you mean the front pulley is still spinning, it is supposed to. It spins any time the engine is running.

If gears are grinding when the tractor is stopped, the belt HAS to be moving.

Greg, I do have the belt guide on the idler. By input pulley I assume you are talking about the big pulley on the trans?

Dan you are on to something here because what I failed to mention is the rear end of the tractor is jacked up and I was testing the brake/clutch with the tractor in neutral. I did not put it in gear because it wasn't off the ground far enough. I need to get my tire fixed and try again. But on Jacks the belt was coming to a stop.
