100 pto clutch problem
 

Guys,
On my 100 we installed the pto clutch and a new wear button , tried to put the grill casting back and there is no clearance to get the mower deck or snow blower belt onto the pto, what could it be ? Thanks :bigthink:

The clutch may not be slid onto the crankshaft far enough or the frame is bent causing the grill to lean back. The PTO bearing needs to be flush to the end of the crank. There is barely enough room to get the belt slid in there when everything is perfect.

Ok thanks , I will check the bearing.

The bearing will not Go on flush and I have hit it on all the way.

Bearing on.

is the basket pulley on the whole way?

PTO bearing is not on the shaft far enough. You can see in one of your first pics that the holes for the PTO are not lined up with the cut outs in the basket. Try again grasshopper. :beerchug::biggrin2:

Nickle does your new bearing have a snap ring on the outside edge? Bearing should go flush with crank snout, I've heard that the snap ring should be removed but can't confirm. Looks like it should go in another 1/8 to 1/4 inch or so, SAMs right Allen screw holes not lining up with cut outs

Ok I will line them up tomorrow, basket pulley is on far enough, no snap ring...

Make sure the key is not sticking out past the basket hub. I had to shorten the key on the engine in my 100 to get the bearing on all the way.

Nick,
Get rid of that stupid brass thingy and put the correct fiber one on.Most pto baskets are about a 1/16 away from the sg bolt,no locking washer is to be behind it.

That "brass thingy" lasts a lot longer than a fiber button plus doesn't break off when changing belts.

yes but on a 100 there is very little room for it to clear the grill.

That's why I make them the same thickness as factory :biggrin2:

Do the brass ones go clear through and out the other side with threads? Looks like Nikodemis has a nylock nut holding it on? I was under the impression they were all press fit?

I also think the PTO isn't far enough on. The fiber buttons work just fine for me...

I believe my problem is that I don't have the pto holes lined up with the basket pulley slots, key way is flush, there is a lock washer on the bolt but it always had one.

The bearing is not on the shaft far enough. It needs to be flush with the end of the shaft.

The brass button is not the problem. I have one on my 149 and it works just fine. It's dimensionally the same as the fiber POS.

Yes but on a 100 the grill is close to the pto arm as it is, the nut puts it that much closer and harder to put on the belt.

The brass button is a press fit just like the fiber button. Nick must have added the nut.

Nick

This is what the bearing should look like. You'll see it fits flush with the end of the shaft.

thanks sam, mine will not go on flush, and there isnt much more room the basket pulley can go back, i dont think it ever went on flush.

mine has a threaded end, no press fit, thats why its on there, i wonder if it would stay in without the nut?

Never seen one that was threaded. Who did you buy it from?

A guy who lew knows who works in a machine shop.

I've seen a few that were threaded, seems like a good idea if the hole in the arm is a little messed up and a press in button won't work.

I'm going to say this only because it hasn't been mentioned yet and because no matter how much mechanical work we do we can all make mistakes or overlook things.

If you haven't done it already, check to see if the locking collar for the bearing is positioned on the back of the bearing inner race in the unlocked position yet all the way up so that it is as close to the back of the bearing as possible. If the locking collar is turned the wrong way and not setting on the shoulder of the inner race it could be holding the bearing out a good little bit.

Guys, I think I fixed it, I got the pto on a lot further by lining up the set screw holes with the basket pulley slots, I also got the bearing on flush by using the original locking collar, although that probably doesn't have anything to do with it.

Do the long pto set screws go in first?

Sure do.:IH Trusted Hand:

I got it all back together but it turns over hard.:bigthink:

It turns out the battery was just weak, the pto works great.:beer2:

Good job Nickster. Glad you got it. Now just do it another 10 times and you'll be a pro. You're lucky that out of all your tractors you haven't had to mess with a Pto until now. :bigthink:

Yea, thanks mike, I've removed them before though.:biggrin2:
