Divemaster2000 13 #1 Posted September 5, 2021 Hi! I am curious about the 'mule drive' on my 520H. When replacing the two pulleys (one "v" and one "u" channel,) are there any other parts needed, or do they just go onto the axle/rod of the Attach-a-matic? The "v" pulley goes on the inside? It looks like the part numbers are 104974 and 105975, if that is all that is needed. Are aftermarket parts worth buying? Does anybody have any recommendations? Thanks!

AMC RULES 37,130 #2 Posted September 5, 2021 Pretty sure there are a couple spacers needed in there for alignment purposes too. Share this post Link to post Share on other sites

I read a post a while back by a member pointing out that the mule is particular about the spacing--be sure to use the same width of hubs on the pulleys and put the spacers back in the same order as they came out! 1 Share this post Link to post Share on other sites
daveoman1966 3,745 #5 Posted September 5, 2021 You can find the after-market pulleys for 104974 and 104975 as a set of Ebay...$50 bux or so. Share this post Link to post Share on other sites
Divemaster2000 13 #6 Posted September 5, 2021 (edited) Thanks! What is the part number for the spacer? It might be that is all I need, as it seems to be missing. {Edit- it looks like there two spacers from that diagram. Where can I find part numbers?} Also- is 102742 the correct belt? Have a great day! Bob Edited September 5, 2021 by Divemaster2000 Thought of another question. Share this post Link to post Share on other sites
peter lena 8,588 #7 Posted September 5, 2021 @Divemaster2000 as you take the drive apart , lay it out , to refit , there is only 1 spacer between those pulleys . also lightly , sand that shaft and use grease to remount. recommend while you have the opportunity , to use lucas hi temp , anti sling polyurea grease in those new bearings . small pocket screwdriver , easily pop off the bearing side shields , wipe out " grease " replace with the lucas x-tra heavy duty , $ 5 , walmart . not long ago did the same new pulley swap on a pto drive . no whining , no noise , no failures . use this on every bearing , those 6203 , bearings get quite hot , and lubrication fail . realize that just saying this is terrifying to many , but why not stop a problem while you are there ? grease is rated for 560 deg drop point , use it in all my deck bearings , quiet smooth operation . sorry if I threw you of course , my 3 horses are set up the same way , with no repetitive bearing failures , pete Share this post Link to post Share on other sites

squonk 41,040 #9 Posted September 5, 2021 https://wheelhorsepartsandmore.com/ They have the pulleys. I'd link the pulley page but looks like they got hacked By ED enhancement ads! 1 Share this post Link to post Share on other sites

Divemaster2000 13 #11 Posted September 5, 2021 (edited) It's a 42" deck. When I said it looks like there are two spacers, that included one between the shield and the outer pulley (closest to the nut.) I will pick up that Lucas grease, thank you. Wow, Amazon is charging over $17 for what is $5 at Walmart... Edit- I see what you mean about them being hacked.

lynnmor 7,302 #15 Posted September 6, 2021 I always go to the Toro website to look up part numbers, then do a search for the numbers needed. For example, here is my deck mule: https://www.toro.com/en/parts/partdetails/?id=5529 Share this post Link to post Share on other sites
Divemaster2000 13 #16 Posted September 6, 2021 I couldn't find the information the Tory website, it could be that I am using the wrong terms to search on. I did find a post from 2019 (see below) that looks to have the part numbers. Thanks for the input! Front idler assembly mule 1/2" long spacer part number 101757 is on the outside between the pulley and cover. 5/8" long spacer part number 101734 is between the pulleys. Spacer ID needs to slip over 3/4" shaft. Garry 1 Share this post Link to post Share on other sites

Divemaster2000 13 #18 Posted September 8, 2021 lynnmore- I have tried, but I wasn't finding a part diagram that showed me the spacers. I'm not sure why. So, I went with the post from Garry, and ordered those spacers. Share this post Link to post Share on other sites
