I've tore down the left final, replaced the 8 fictions, resurfaced the pressure plate, put pressure plate on, torqued bolts, it seems like the pressure plate fingers are awful close to the main body, they only have 1/2 to 3/4 of an inch of travel. Just don't look right. Is that the way they are suppose to be???? There is no spec.s on how close they are suppose to be in repair manual..

Thanks

When you resurfaced the pressure plate, you changed the relationship between the pressure plate and the disk stack. One way to correct this is to put an extra "steel" in the stack to compensate for the metal you removed form the pressure plate surface.

I didn't remove that much to add another steel plate. I'm out flush with the edge of the hub now. When I tore it apart, they had 0ne extra fiber disk on the hub, instead of 8 there were 9 fiber disk.

I don't have the information on a 1010, but this is what a 420/430 clutch pack should look like.
A 420 uses 7 fibers and 6 steels.
The fibers should be from .145"(min) - .151"(new) thick
The steels should be from . 090"(min) - .096"(new) thick

Total stack height of the 7 fibers and 6 steels should be 1.555" (bare min) to 1.633"(all new)

This information is in the repair manual, not the parts manual. The 1010 might be the same, but I don't have that particular repair manual.

Your problem is caused by either the stack is not thick enough or you removed more that you realized from the PP. It only takesa few thousandths to make a difference. On a 420 the difference between all new and minimum is only .078" (78 thousandths) A little wear on the steels and a little wear on the hub and a little removed from the PP and there you are.

1010C uses 8 fiber and 7 steel. It is not that the stack is not thick enough, it seems as the PP fingers are to close to the main body of the PP. The 1000 series manual calls for 8 and 8, but if you put in 8 steel, it would put final steel disk against PP, would be metal to metal. The stack is a little higher than the center hub,,, new fiber and steel measured correctly.
Our local JD dealer has no manuals for industrial equipment, so I will have to check with PAPA' when I get back from Portland, OR. Just to need to find out if there is a gauge for the friction PP

Thanks Keith
