heysavoy 16 #1 Posted June 3 (edited) Hi. I am hoping someone can help me? I have a 1990 WH tractor Model 31-12KE01 with hydro static tranny and while cutting today my tractor just stopped. I heard a banging noise and then it wouldn't go forward or in reverse. I believe it may be a belt that sadly I didn't know I had. Certainly have had to change all the others but not this one. It's still intact but appears damaged. 1) not sure if that's the problem 2) not sure what belt it is or what it's called and 3) not sure how to remove. I assume I have to take all the parts off I have marked (side panel, etc.) Any help would be appreciated as always this website has been a lifesaver over the years as I continue to try and keep the ole boy runnin'. I did get the belt off and it is a NAPA 5L820W 2ddk Edited June 3 by heysavoy Share this post Link to post Share on other sites
953 nut 55,188 #2 Posted June 3 You are correct about having to remove the belt guard and PTO belt. The drive belt form your tractor is Wheel Horse part # 108501 which is an 82" by 5/8" belt. The Kevlar belts from Tractor Supply work well and are genneraly in stock. 2 Share this post Link to post Share on other sites

I removed the belt guard and PTO belt. I'm hoping I can slip the belt over the fan in the rear that I see and those 2 parts are all I will need to take off. Waiting on new belt to arrive. Any idea on where to find a diagram on how to install? Edited June 4 by heysavoy Share this post Link to post Share on other sites
oliver2-44 9,732 #4 Posted June 4 While you have the belt guard off check your idler pulley. A bad bearing in an idler pulley can ruin a belt. Also check the idler spring is in place and not stretched out looking 1 Share this post Link to post Share on other sites

Do you know if I can replace the belt without removing the rear tire or the fan that sits near the idler pulley? Share this post Link to post Share on other sites

I find it easier to install the new belt by removing the idler pulley and the tensioner spring. Put the belt on the hydro pulley first, then on the engine pulley. No need to remove the fan or wheel although it does make it easier to work with the wheel off. Then, after checking the pulley bearing, install the pulley and then using a flat screw driver or brake spring tool to install the spring. 2 1 Share this post Link to post Share on other sites

peter lena 8,609 #9 Posted June 4 @heysavoy agree with others on related opportunities , rear wheel removal / jack stand , is solid safe , often refer to RELATED DRIVE POINTS , any rough / sloppy / binding movement connection , should be addressed , while I am there would also suggest , verify how things work ? add a washer / firm up connection ? dare I say lubricate a RUSTY CONNECTION ? the time to improve things is when / how you see it . my experience with movement anything , is that it can be enhanced , with detailing . as said ,numerous times that , PTO LEVER , SIDE OF DASH start point , is a GOLD MINE , for movement improvement , also agree with , tractor supply aramid , belts . only suggestions . pete 2 Share this post Link to post Share on other sites

No it was not completely broken but definitely frayed which was somewhat of a blessing as it allows me to see how it goes on and I also used the belt for a replacement part number. Now I need to see how the idler pulley comes off and how big of a deal it is to take off the tensioner spring as well.

There are many ways to do this, of course, but my preferred method is to use vise-grips to it give me a very solid hold on the rearward end of the spring and use the screwdriver to guide the hook end into place. 1 Share this post Link to post Share on other sites

Ed Kennell 38,134 #14 Posted June 4 Easy peasy with a brake spring tool or a large flat screwdriver. You can easily make a tool by grinding a groove in a piece of 3/8" round rod ar grind a groove in an old screwdriver. 1 1 Share this post Link to post Share on other sites

Handy Don 12,212 #16 Posted June 4 Notice how on removal, Ed held his right hand back from the end he was detaching--that way when the spring retracted, the hook end didn’t bite him--I suspect that was learned behavior! 3 Share this post Link to post Share on other sites
Lee1977 6,656 #17 Posted June 5 I use a 1/8 steel rod with a short hook on the end with a pare of vice grips clamped on it. From behind the tractor where I can see the spring hole in the axle housing' Once the spring is in the hole I turn the rod up and push it from behind the spring. i can see the hole in the axle flange 3 Share this post Link to post Share on other sites
