TimH 105 #1 Posted November 30, 2017 82 old Friend brought his 312-8 into my shop. He took some parts off to clean and could not figure out how to re install what I think is a belt stabilizer . I have a 312-A Sh that will not be any help. Anyone know from the pic were the bolts go ? Doesn't look like I have it right before I tighten the bolts up.

clueless 3,012 #3 Posted November 30, 2017 If it's the part in the picture with the two nuts for adjustment, it's the early version of the clutch engagement damper. About a year ago I was putting my 312-8 back together and couldn't remember where it went. I put a picture of it on RS, everybody said leave it off, so I did, haven't missed it yet. 2 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,102 #4 Posted November 30, 2017 The drive belt on the tractor looks to have raw rubber sides. They should be fabric covered like the top and bottom so they slip on the drive pulley when the clutch is applied. Perhaps that is why the dampener was worked on.

Racinbob 11,237 #5 Posted December 1, 2017 It's definitely not needed. If you decide to keep it on the tractor it looks like it's adjusted wrong and the body of the damper is stopping the clutch arm and not allowing full tension on the belt. Obviously that's not good. I would make it go away. Share this post Link to post Share on other sites
TimH 105 #6 Posted December 1, 2017 We figure it out Tried with out part on and caused shatter. Installed it and no more chatter. Belt does need replaced It's on it's last adjustment. On order from local Toro dealer. Like I said friend took apart to clean and paint. So while it was here we finished installing his weighted rear Tires and chains. Change his trans lube air filter and oil. De carboned valves and New head gasket. Installed new foot pads from Eldon Glatfelter. Old guy left happy and loved the price He did ***** about the price being free. LOL 3 Share this post Link to post Share on other sites
Racinbob 11,237 #7 Posted December 1, 2017 (edited) I had the gas damper on my 2005 when I got it. I removed it and got the 'chattering' too. The belt didn't look bad but it doesn't take much. I replaced the belt and all was fine. That was in 2009 and I'm still using that belt. Replace your belt and I'm sure you won't get the chattering if you want that device removed.
