Lagersolut 669 #1 Posted January 27 Getting spare drive belts for my -2005 - 315-8 classic and 1986 416-8 Kohler K341 single cylinder - the parts diagram lists a 7473 and 108501 for the 416 - the 6 digit number is a lighter belt compared to the 7473 .....315 8 takes the 7473 - think I ran into this confusion a few years ago I'm trying to get my bearings straight on these belts . 5/8's on the 7473 - 7/16th's on the 108501 Is there a reason a lighter belt went on a 400 series 8 speed ?

Lagersolut 669 #5 Posted January 28 The 416 was produced with 2 engines and 2 transmissions - parts page lists both belts - one for auto vs 8 or Kohler vs Onan ? https://www.jackssmallengines.com/jacks-parts-lookup/manufacturer/toro/riding-products/1986/31-16k802-416-8-garden-tractor-1986/drive-belt-and-pulleys Share this post Link to post Share on other sites

Transmission drive belt 78-7100 replaced by 7473 - HB x 81.9" or 5/8" x 81.9" or You're right Gary it's 7473 - after digging deeper into the parts list posted and what my parts place came up with - they had it at 108501- so does Jacks - both wrong - too short ( just tried to install it ) brought another belt home supposed to be a 7473 but she gave me the wrong one - a 7478 - 84" belt - entering this in my notes so it doesn't happen again. So now I have 2 belts to take back exchange for the right ones - number on the old belt is almost gone - was able to decipher with a little cleaner and scrubbing Share this post Link to post Share on other sites
