Drive belt length

Recommended Posts

BillF

Guys, I'm really struggling to find the drive belt length for my C-120, 8-speed  (12HP Kohler). I've ordered the wrong belt, twice now. :(    Can anyone take a peak at theirs and help a guy out? It should be in the ballpark of 5/8 x 81"/82" but I need an exact before I reorder.

The toro website calls for belt # 7473.  Here are the dimensions of it.

Disregard the Gates an d Rotary sizing...wrong belt.  Just go with the TORO or Wheelhorse belt # 7473

Awesome! Thank you Dave! 
How did you find it? When I type in the model number (k301s - from the metal tag) I get no results.

Go to the TORO siet here:  When you open it, type in your model C-120.  It will then list the production years and select any of the 70s m,odels.  Then schematics will pop up and you can see all the schematics of the tractor.  You'll have to play around a little...like all websites, but this is a very good one.

Once you determine the belt # (7473), go to this website to get the particulars of virtually ANY belt ever made...

Enter the belt # as the part #....  presto

I ordered a 7473 wheel horse drive belt and I'm currently trying to stretch the damn thing . There is no way the belt tensioner or lil clutch spring could ever give this 8 speed c-120 enough slack to let the belt slip much less let the clutch pedal return to the depressed position. I seriously don't believe I have it routed wrong . Will it stretch if I use some friendly persuasion and a couple ratchet straps lol.

You should NOT have to stretch a belt...you must have it routed incorrectly, or the wrong belt, or not the original size pulleys on the engine or trans, or idelr.

Here is the manual on how to install the belt.  Make sure it is on the CRANKSHAFT pulley and not the PTO pulley.  Gpo to page 5.2 and study the description on image 5.5.

You cannot stretch modern belts.  If a belt has gotten loose it is because it is worn and sitting lower in the pulleys.

From the posted pictures something looks really wrong.The engine pulley seems to be much bigger than one for a manual transaxle.Secondly there is no idler pulley visible.The idler pulley should be under the top portion of the belt and pulled into engagement by a spring

From your 1st pic, it looks like the belt is not on the engine crankshaft pulley.  That pulley should be #7466 and is 4" diameter.  Look behind you clutch disc and be CERTAIN the belt is in the V groove of that pulley and NOT riding on the edge, or hung up on anything.

The idler pulley is laying on the ground in the pic.

Dave I appreciate your help, it is most certainly in the crankshaft pulley and the belt spins as it should it just seems this belt is to damn short. I'll check to make sure it's a 4 inch pulley but it def appears to be from what I can tell. I compare the old belt with the new one and it appears to be about 1 inch shorter. I woulda figured a plus or minus a 1/4 at most.

I went ahead an ordered the napa 5l820w. Thanks for everyone's help on this odd frustrating situation I'm sure the belt is just the wrong size although I remain confused by 7473 wheel horse markings on the belt the fact remains it's too short. On ward and upward boys ..

      Hi guys, I purchased my firs WH - a 1976 C-120 Automatic. I have a steep hill on my property and before I go down the hill, I want to understand how my braking system works. I’m aware that this year/model didn’t include disc brakes, so is the breaking purely hydraulic Via transmission and controlled by the speed lever? Has anyone encountered issues with this? Is it safe to use on a steep hill? Any input is greatly appreciated. Thanks!

      Sadly Dan @Achto informed me the the other day of a 857 and a C-120 that was deposited at his local county dump. Dump rules are  such that once it hits the ground it stays due to junkyard dogs going to fisticuffs over scrap steel. Understandable  Despite some hastily made plans of bribery,  chicanery and/or hook or crook to rescue them we failed miserably. We may get drummed out of the Mafia for that one.
      I'll let Dan fill you in on the details if he has the stomach.  I would like to believe that that our beloved  ones would be smelted down to produce more tractors but then I wake up from that dream. Sorry no bone yard pics not that we would want to see them.
      Dan asked me if he had a problem over grieving over these lost gems. You decide... So in memoriam I feel it is quite nescessary to post pics of our lost loved ones. Since I don't have a C-120 here's what I have of a 857.  Please post your pics of either models. True story, I wouldn't hose you guys and not just fishin  for

      One seat spring is about 1/4" lower than the other one. Has anyone had this problem. If so, what'd you do to fix it?

      Homer is a typical Southern man. When a tool breaks, he moves it to his backyard to be repaired another time. Turns out I'm the repair guy and have been attempting to barter for an old C-120 and a Commando 7 buried in the yard. He surprised me with the C-125 black hood a while ago after numerous mower, chain saw, weed wacker and whatever repairs. The horses are all out of a shop in Joplin now gone after the big blow... Soooo, 1 repaired old Sears LT and another that I took apart just so he could see after running without oil that the cam was in 4 pieces and the rod in 5 and he said I could have the 120. We pulled it out of the dirt with 4 flats, destroying several ant mounds in the process. Truly, not bad condition thanks to Homer's attention to the use of tarps. He tells me the 301 was bored .030 over and his mind is sharp for a 92 year old so I'm inclined to believe him. May be able to save that Commando in the near future if I repair that old Bolens GT14 first - and so on. So, my collection is now at a lowly 2. I don't think I'll restore this - will just make her a reliable runner and make the wife happy The deck can use a little metal but seems salvageable. Another C saved!

      I sold this last fall. 1975 C-120 Auto. The buyer called and asked if I wanted it back. I couldn't  say no. He put about 4-5 hours on it. The war dept. told him him he had to chose between a motorcycle or the WH.
