Sparky-(Admin) 21,314 #1 Posted July 13 On my 857 the belt kinda stops when the clutch is stabbed…but ya really have to be pressing hard. And I missing anything on the inside of the guard? And the tab thingy on the idler pulley, it’s not adjustable but does it look correct? Am I missing something to assist the belt stopping? Just installed a brand new belt, both new and old do the same thing. Share this post Link to post Share on other sites
wallfish 16,994 #2 Posted July 13 Try adjusting that little tab on the front of the belt guard and below the belt. Maybe to 1/16-1/8 off the tight belt. Hard to tell from the pic but it appears like it's bent down a little 2 1 Share this post Link to post Share on other sites

wallfish 16,994 #4 Posted July 13 The belt dust on the guard looks like that idler tab might be riding on the belt when it's engaged. Bend it up a tad 2 Share this post Link to post Share on other sites

Handy Don 12,208 #6 Posted July 13 Just now, wallfish said: Grinding off the welds will make it adjustable The idea is to have that tab contact the belt only when the clutch pedal is down and the idler arm is rotated forward toward the engine. Share this post Link to post Share on other sites
squonk 41,056 #7 Posted July 13 Make sure your brake adjustment isn't too tight. I had the same issue on my 857 and the cause was the new band I put on caused the linkage not to move as far as with the old worn out one. This caused the idler pulley not to release enough. 1 5 1 Share this post Link to post Share on other sites

Alright! @squonk for the win! Brake was adjusted up “tight” and loosening it so it doesn’t grab so quick has helped. She isn’t perfect but at 57 years old it’s ok to have a couple rattles 1 1 Share this post Link to post Share on other sites
peter lena 8,606 #10 Posted July 13 @Sparky would also consider the original style / type of pulley , and ALL RELATED LINKAGE MOVEMENT POINTS , would bet that there's a related bearing hang up , would only take a incremental bearing hang up to start , total shuddering , bouncing . just sayin , pete Share this post Link to post Share on other sites
stevasaurus 22,713 #11 Posted July 13 It looks to me like your input pulley on the trans is a bit rusty. If the engine drive pulley is like that also, they might be your issue. Clean them up with a wire wheel, wipe them with Mineral Sprits and wipe the belt also. The guide on the tention pulley is just fine...it just keeps the belt on that pulley. 3 1 Share this post Link to post Share on other sites
stevasaurus 22,713 #12 Posted July 13 Here are the pictures of the guard off my 857...I have no issues. I do nt have the front tab but I do have the "Wallfish Fix" by the drive pulley. Share this post Link to post Share on other sites

ML3 1,195 #17 Posted July 13 Made one for the rat rod Suburban. Didn't have a belt guard however if I did it wouldn't work anyway. Predator 212 & RJ transmission that's lowered on frame. 3 1 Share this post Link to post Share on other sites

I had firstly lots of trouble with a continouse gently friction of the Belt on the Gearboxpulley - it wouldn‘t stop. So the Clutch won’t work corectly and the Brake engages too early. First after i adjusted on the Gearbox the Guard over the Gerabox littlebit to front as John suggested ( what is welded on your Side) it begins to keep the Belt tighter but there was also still friction on the Belt while clutch was despressed. A closer inspection shows me that both - the upper belt support and the lower belt support as in this picture from Mike be good visible must be as close as possible to the Belt without touch it when clotch is engaged. first if the Clutch is pressed the belt moves out and hits firstly the lower belt support. The upper Belt support was important to keep the Belt in shape and not be too sloppy. After my tests and tries i found a good setting (similar to that Pict from Mike) it worked as it should without any noise. after that i remodeled the Sidecover a bit to fit to the new bigger Pulley. that worked like a charme now for over 2 years. a gently deformed cover let sometimes the pulley on the Gearbox gently scratching the Cover That was removed with a Washer on the rear to get little more distance between pulley and Cover. 3 1 Share this post Link to post Share on other sites

If you look little closer on the Upper front, you can see that i shortened the Cover at about 1,5cm. than i grinded down and rewelded the lower Beltsupport at this 1,5 cm backwards. The upper beltsupport was scratching the Belt. To prevent this i cut the cover app. 3 cm deep and mold it little upwards an welded a piece of Sheetmetal like a gently Wave. when exactly look at this Pict in the Front you can see my „ lift“ on the front of the Beltcover.

Retired Wrencher 5,450 #23 Posted July 14 Mike. What I have found is when everything is working perfect and adjusted right you will have a whistling sound when it comes to a stop. This when it right. And of course a Wheel Horse belt because of how they fit. I only run these belts. They have never failed me. 1 Share this post Link to post Share on other sites
stevebo-(Moderator) 8,330 #24 Posted July 18 I just replaced belt on my c165 and same issue. I think I need to adjust the tab on the idler pulley slightly forward more so it grabs on the guide below when clutch pedal is pressed. 1 Share this post Link to post Share on other sites
