stevebo-(Moderator) 8,330 #1 Posted March 24, 2012 All- I need to replace the center spindle and pulley on my 520's 60 inch deck. If you have either part or a manual so I can locate these parted that would be great. Thanks! 1 Share this post Link to post Share on other sites
rmaynard 15,431 #2 Posted March 24, 2012 Do you have a model number? What year is the 520? Share this post Link to post Share on other sites
stevebo-(Moderator) 8,330 #3 Posted March 24, 2012 Bob, The deck is off one of the newer 520's with the rollers on the front and not the skid plates. I think it is around 95/96?? The model number for this deck is 78390 1 Share this post Link to post Share on other sites
rmaynard 15,431 #4 Posted March 24, 2012 I found the parts diagram at Toro. Spindle housing is a 113516. Pulley is 113054. https://lookup3.toro.com/partdex/index.cfm?xCaller=Toro&lang=us_en Share this post Link to post Share on other sites
stevebo-(Moderator) 8,330 #5 Posted March 24, 2012 Thanks Bob. Based on serial number it is a 1994 deck. I just bought a double pulley off ebay for 35 with shipping. I need to figure out if I need the spindle or that tube thing... i will have to take another look at it. Wow these parts are pricey... 1 Share this post Link to post Share on other sites
a66gt40 1 #6 Posted April 12, 2023 I was hoping someone could help me out with the size and dimensions of the center spindle deck pulley? Part number is 113054. It's off of a 520-HC 60" deck. I'm not sure about the serial number on the deck. I do know that it's the one with the sleds on the front and I'm thinking that it's the original deck on the mower. I bought the mower last year to restore but I can't find the pulley anywhere nor the dimensions. I have been restoring these mowers just about all winter and have bunch but this is the only commercial grade that I have found as of yet. Please help. I have a seller on ebay who may have one that will work but I don't have the measurements. Thanks in advance. 1 Share this post Link to post Share on other sites
