installing trans pulley on C160

[jwalk2c 0]

Hello everyone,

Just found this forum. WOW ! Lots of post here.

I am putting back together my 1976 C160 .

I had to take the differential in to shop after some idiot

(me) was trying to take the rear hub off .

Instead of using a puller I though I would beat it off with a hammer and piece of wood.

Guess what gave first, the snap ring holding axle in place.

Since the trans had a lot of hours I had them put bearings and sync also.

I did not take the tractor to shop , just the diff/trans.

I am putting the drive pulley back on the trans.

But it is a little tight, and even though it is fairly easy to drive it on shaft, there is no way to put any back pressure on shaft.

Since there is about 1/16 or slightly more in and out play on drive shaft , the pulley bottoms out against the case as you are driving.

This leaves about 1/16 or slightly more distance left before pulley would be flush with end of shaft.

It just does not look right. My pulley takes a set screw to hold it on.

There is a hole in pully grove to insert hex drive.

Thank You Very Much

jwalk2c, welcome to RedSquare glad you found us. I'm not too sure about that pulley, do you have a picture you can show? I haven't taken mine off, but I can check yours against my 414-8 to see if they look similar.

Again :thumbs:

Hey jwalk2c, welcome to Redsquare!

If I'm following you correctly, you've got a little bit further to go to get the pulley on the input shaft, but the play in the shaft (in/out) is enough to make the back of the pulley contact the seal. Sound right?

I would say that if your beltguard will go over the pulley without it rubbing, then don't force the pulley any farther onto the shaft. In other words, leave it like it is. The input shaft seal is very thin, and the in/out play of the shaft is enough to allow the pulley to grind it and the space to put a new seal out altogether. I've got an 8 speed that did exactly that. Now there is no way to replace the seal, as the seat is wallowed out beyond repair.

It only leaks a little, but it can't be repaired. You don't want your tranny to do the same thing.

Good luck!

Ok Ok

This is a game of patience ..... get a block of wood (a 2 x 4 will do just fine) and a good sized hammer.

Now clean the shaft up good with some fine emory cloth.

Next use the block wood and hammer to drive the pulley back on.

When the shaft is almost through the pulley keep pulling the pulley away from the transmission housing .... you are only going to have the friction of the shaft in the bearing to hold the shaft in place when you hit the pulley but it will work if you hit the pulley enough times.

Thanks all for the fast help.

Yes kpinnc you are right , I have a little farther to go

before pulley is all the way on shaft..

I was not thinking about the seal though , hmmm?

Good point.

I may try BPjunk suggestion , If I would have cleaned the fresh paint

of the shaft I may have not had as much a problem.

Thanks for the offer to look at pics nylyon

I will try to get one up this weekend if after trying BPjunk suggestion

pulley is still not on all the way.
