Davidschaffer 0 #1 Posted July 10, 2016 I have an 89 520h with a 48" deck. What size/number pto to deck belt do I use and where can I find one? Thanks Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,511 #2 Posted July 10, 2016 This is not necessarily the deck model you have but the belts are the same. Have a local Toro dealer? Garry Share this post Link to post Share on other sites
Davidschaffer 0 #3 Posted July 10, 2016 Thanks. No local Toro dealer. Would it be considered the drive belt? Share this post Link to post Share on other sites
Kurt-NEPA 755 #4 Posted July 10, 2016 From my note for my 48"SD on my 1988 520H. PTO to Deck Belt Wheel Horse 1594 - Toro 102742 - superceded by 94-1501 103" Long - 1/2" HA Belt 1 Share this post Link to post Share on other sites
Kurt-NEPA 755 #5 Posted July 10, 2016 (edited) Search on Ebay for Toro 102742 It will pop up several. I've bought from Killian's many times. Great supplier If you are in a hurry try Tractor Supply - get a 1/2 X 103" belt. They carry PIX Kevlar belts. I've had very good luck with them.

Yes the pto to deck belt is the mower drive belt. The spindle belt drives all the spindles and blades. Garry Share this post Link to post Share on other sites
Davidschaffer 0 #7 Posted July 13, 2017 (edited) Now the drive belt broke. All of the sudden she rolled to a stop. The cooling fan blades are broke off too from hitting a big stick the wrong way last week. Where can I find a cooling fan and what size drive belt do I need? Are there directions anywhere on how to put a drive on? Thanks Edited July 13, 2017 by Davidschaffer Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,511 #8 Posted July 14, 2017 Fan available from Toro http://www.partstree.com/parts/toro/parts/108393/ Transmission drive belt is listed on this page Garry Share this post Link to post Share on other sites

What about the idler pulley? It does not spin freely. I replaced it years ago and it always squeeked. The local parts shop said it was the right one but It sure didn't look like the same one I had taken off. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,511 #10 Posted July 14, 2017 This one is for the 520-H tractor drive belt. The 520-HC model uses a different one. The most expensive from Stens has a real ball bearing that should last forever https://www.rcpw.com/search/?quest=112426 Garry Share this post Link to post Share on other sites

That is the one for the 520-HC tractor model shown in the original parts list. The on-line lists show both but fail to identify what tractor uses which one.

Davidschaffer 0 #13 Posted July 18, 2017 The parts arrived and I'm not quite sure what went wrong. I know the idler pulley that was on there was not the original but it's hard to believe that it would fit being so much bigger. I can't seem to get the new pulley to work with the new belt and the pulley rubs on something, I think the spring. The old pulley squeakd a lot so I t was probably rubbing too. I think a washer would take care of that problem but I'm still not sure how to get the belt on. It seems the belt will rub against itself if I pry it over the pulley. Any thoughts? Also, there is a hole behind the idler pulley screw that the screw goes into. That makes it so the pulley can not travel. Is that normal? Thanks Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,511 #14 Posted July 18, 2017 Looks to me like you are missing items 44 and 49 What is the model number and serial number of your tractor? I'm starting to think it is not a 1989 model. Garry Share this post Link to post Share on other sites
Davidschaffer 0 #15 Posted July 18, 2017 I got it from the original owner whom still had all the books and receipt. I haven't looked at that stuff in a while though.

gwest_ca-(File Mod) 10,511 #16 Posted July 18, 2017 The 41-20OE01 is a 1990 model and the idler pulley for it is the 112791. I would say the bolt should not enter the hole in the chassis as that would eliminate the spring tension on the idler. http://www.partstree.com/parts/toro/mowers-lawn-garden-tractor/41-20oe01-520-h-toro-520-h-garden-tractor-1990/clutch-brake-and-speed-control-linkage-520-h_1/ Garry Share this post Link to post Share on other sites

Homewrecker 0 #21 Posted March 31, 2021 What is the difference between the 520h and the 520 HC and how do you tell them apart? Share this post Link to post Share on other sites
Handy Don 10,656 #22 Posted April 1, 2021 (edited) Can't recall all the details, but the HC was intended for commercial users. Most of the differences got rolled into the 520-H over the years after 1989 Some differences: - decals! - adjustable and sturdier tie rods as well as stronger tie-rod ends with grease zerks - thrust bearings on the spindles standard - roller (vs. ball) bearings in the front wheels - 16x7.5-8 fronts vs. 6.5 - 23x10.5-12 rears vs 8.5 or 9.5 - both had 1 ⅛ rear axle - 400 CCA battery vs 260 - lights and gauges for temp and oil vs. gauges only - nicer latch handles on the front- and mid-hitches - different hydraulic cylinder and lever arm for the rockshaft. --- This one made me curious when I read it a while back. I've asked Lowell about it and he didn't have an answer. If you can get to it, @Homewrecker, I'd appreciate you measuring the outer diameter of the cylinder, the diameter of the shaft, and the length of the throw. I suspect the HC had a more powerful lift than the H's. Edited April 1, 2021 by Handy Don Share this post Link to post Share on other sites
