Well I got everything back together tonight and decided to drive it for the first time. it started right up but the front belt wants to slip when I put the Vari Speed in gear. It takes fine rubber off the belt. It is hard to see what is happening but it looks like the center pulley is not moving letting the rear belt move. I know it is free because I just had it apart the other day. Could it be all the paint on the pulleys making it slip? It will move the tractor but not very fast and it makes a lot of belt slipping noise when it does. Any idea what to look for?

The front belt needs to be a good one, if it's too narrow it runs on the bottom of the belt instead of the sides. This happens on the crank pulley and you can see it touch the bottom of the grove if it's too narrow.
The rear belt doesn't matter so much as there is a lot of adjustment in the rear sheaths to make up for a worn rear belt.

Both belts are brand new Massey Belts. I checked all the adjustments for the rear pulley and they are right.

The center sheath in the middle of the double pulley moves back and forth freely?

Yes it does but the pulleys have paint on them, I wonder if they could be sticking to the belt.

2 questions, is the idler tensioning the rear belt well?

When you're in position 1, where are the belts? The one for the rear should be out and the one from the motor should be in, but not touching the bottom.

I would clean the paint off, that can affect belts and may cause sticking as it embeds in the belt.

Ya you might be right there, I think the pulleys work best when there bare metal.

I think that is just back words from what you said. I would have to go out and look. I will and get back to you shortly.

You're right, I was standing on my head there for a second... Sorry. :blush2:

It should be exactly backwards from what I said, except for the idler question.

The rear one is in and the front one is out. The rear tentioner is adjusted to about 1/4 below the top of the frame. It is not the belt that is slipping though it is the front belt that is slipping.

Sorry about being back-aswards there,

The tensioner affects both belts thru the dual pulley. How low in the rear pulley (tranny) is the back belt?

Not very low maybe 3/16 of an inch or so. It is within the specs of the manual because I checked all that when I put it together. My mistake, I checked it after I put it together and then read the manual.

New belts going to be wide and sit high up in the pulley.

Well, it sounds like I assumed. You did it right. You might want to take the paint off & burnish the pullies a little.

That is what I am thinking. Now I have to take that side panel off again. I am trying not to scratch this all up but taking it apart it is hard not to do that. It will be a tomorrow project, I am not going back out there again, it is 14 degrees outside.
