gwest_ca-(File Mod) 10,493 #5 Posted November 16, 2015 Here are the manuals we havehttp://www.wheelhorseforum.com/files/file/1901-snowthrower-38in-1987-1988-w0238-ber-vac-2-stage-om-iplpdf/andhttp://www.wheelhorseforum.com/files/file/1915-snowthrower-38in-1989-w0238-ber-vac-2-stage-om-iplpdf/The belt illustration shows the shape of the belt around the idler pulleys which is very similar to the way Wheel Horse did it on their own snowthrowers.The front idler is flat and the rear idler is a V-idler.It takes a special design of belt to run over a flat idler pulley and the Gates belt 6965 is one for that application.The wide back of the belt is what runs on the flat idler but you likely knew that. Most belts won't last long bending backwards over that flat idler pulley.5H650 sounds like you have the correct belt. The outside circumference of the belt is where they get the length. I usually put a mark on the back of the belt and then run a tape measure around it until I get back to the mark. As a rule belts shrink with age.Let us know what you find.Garry Share this post Link to post Share on other sites
T-BONE 1 #6 Posted November 16, 2015 Looks like the od of the belt is 65.5 and if it has shrunk it could be longer. Would u agree with starting with a new belt at 65" Share this post Link to post Share on other sites

Would u agree with starting with a new belt at 65" That is what I would do.Sometimes B-62 is used to describe a belt with B representing the 5/8" width and the 62 being 62" outside circumference. That is 3" shorter so I doubt that is what it should be but you will know better. Most often B-62 describes an industrial belt 5/8" x 65" (plus 3")An A-62 industrial belt is 1/2" x 64" (plus 2")Garry Edited November 16, 2015 by gwest_ca Share this post Link to post Share on other sites
