daveoman1966 3,562 #2 Posted February 18, 2014 The pulleys are #89 and #92 in the 77-36TL01 schematic. They are part # 104974 and MW8821, respectively. Not sure of the dimensions. The belt in the schematic is #1599 and there are two listings for it. One listing states it as 1/2" x 138" in length and the other states it at 1/2" x 139" long.

repairman 7 #3 Posted February 18, 2014 looks like small pulley 2.5" and on the large 4.25" O.D can somebody confirm this? Share this post Link to post Share on other sites
daveoman1966 3,562 #4 Posted February 18, 2014 (edited) Google 104974 and find it on Amazon. 4.25" seems correct. Ebay for WM8821 and find it in a few other places.. Edited February 18, 2014 by daveoman1966 Share this post Link to post Share on other sites
