Friction disc repair
 
I have to replace the friction disc on my 444. The replacement kit I purchased comes with adhesive on the new disc and instructions for the baking procedure to adhere the disc to the clutch pulley. A Case service bulletin from the 70's I found states that good results were reported from dealers by using contact cement instead of the baking procedure. Contact cement sounds a lot simpler and faster. Has anyone tried contact cement and how did it work out? Any other comments about disc replacement will be gratefully received since this is my first clutch fix.

The baking works best. Contact will work, but, it is not as heat resistant as the factory adhesive. I've done it with success, but I don't think I'll chance it again.

Set your wife's oven at 400 degree for 30 minutes (make sure she is not home or your in trouble) and backe it on also the pad needs to clamped with a round plate. Contact cement is not so heat resistant

That bulletin was then and things have changed. What you more need to focus on is the fact that you need to clamp the disc at 70 foot pounds. That is a lot and that is important.

It is 400 degree for 30 minutes at 80 ft pounds torque according to the manual

"things have changed", reminded me. When I did one with Contact Cement, it was solvent based. Some of the 'eco friendly' stuff is now not solvent based. I wouldn't use that stuff on anything! Tried it once on some cabinet tops, it's worthless!

Thanks all for the feedback. Looks like I'll be smelling up the kitchen.

If you spray and wipe your pulley with brake cleaner and clean it up well, which you need to do anyway, it should not create much odor. I would especially make sure the mating surface has no remnant of past adhesive or disk on it. I use the wire wheel on my bench grinder.

Oh, there is a bearing in it that you need to remove. You need to replace all 3 bearings while this is all going on. It will quite the operation not to mention when they really go bad, they wipe out expensive other pieces.

The wavy washers cost a little more and it would be good to replace them. But, not everyone does that. They are crucial. They are half of your friction pressure. The lever closes the gap via the cams. The wavy washers push back from the other side.
