I have a 28" RER of 1980's or early 90's vintage. It would go about one or two turns around the yard and quit moving. I figured the rubber-edged drive disk was worn, so I bought a replacement, and also got the paper-type clutch disk. I took the part with me. Neither me nor the shop guy noticed the difference in the rubber disk. The new one didn't have a brake lining. I put the old one back on with the new friction clutch disk and it worked fine like that. Question is, can I still use the different rubber disk or will it not be a good fit? This is my late Dad's old Snapper he gave me a few months before he passed away. Just wondering if I need to return it or can it still be used. Don't have any hills to mow so not worried about sudden stops...

I think you need the one with a brake lining. With lining is for the smooth clutch. I don't think it will work w/o the brake lining.

You can get that liner separate but it is a little bit of a bear to put in. ANY self respecting parts man should have know when you brought the old one in and with the fiber disc you describe, that you needed the one with a liner. That fiber disc is just a spacer, it is not intended as a friction surface. Did you get part of it wedged between the rubber tired drive wheel hole and the raised shoulder on the drive hub?

As said above, I am surprised it worked at all.

I agree with Walt. That must have been that parts man's first day. The clutch without the lining does not use the fiber disc, which basically does nothing but keep the clutch from flopping around. You have smooth-start and must use the one with the lining.

Yeah, I was surprised when I tried to put it on. I don't know if it was clear from my post, but I just put the old one back on, with the new paper friction disks, and it ran fine. That was probably the whole problem, but I bought this one a long ways from home while traveling, so returning it isn't an option, lol.

Oh, Walt, no, I don't think I got it wedged in, I held it in place and got the fiber disk perfectly centered around the hub and the bolted the rubber disk back on, and it ran fine, mowed the whole yard with zero slippage. It's stored at my rental house. Next time I go over, this weekend, I'll raise it up and take some pics.

I don't know how it is providing any driving force except it sounds like you sandwiched all those fiber disc in there together. As said above, those are not there for friction driving force, just spacers.

Don't really need a picture, been working on them for 40 years or so, point is, it is not assembled right.

Ahhh, I wondered about that. The guy at the shop who sold me the wrong part was telling me that the fiber disk provided the friction to turn the rubber-tire disk. He also told me you could use two fiber disks, maximum, so I used my old one, which was worn and glazed, slightly, and the new one together. Don't know why, but it did work that way and I mowed the yard with it. Hmmm, I REALLY need to look at it again.

I should also point out that my dad told me he had had the clutch replaced numerous times in the past. I attributed the wear to the steep hills around the house, but it is possible whoever did the work before might have missed something at one point. I'll check the numbers and everything and make double sure the right parts are on this mower, lol! Thanks, and I'll get back to you this weekend...
