Ashton Vancoutren 36 #1 Posted August 3, 2022 Does anyone know what size the drive belt from the engine to the deck would be on a 502? Share this post Link to post Share on other sites
ri702bill 8,296 #2 Posted August 3, 2022 (edited) Download the RM 361 manual - part 71, WH Part Number 1577. It is a 1/2 wide V belt, 28 inches long. Check your tensioner pulley - the bearings take a beating and are replacable - same pulley as the engine drive belt tensioner. Bill Edited August 3, 2022 by ri702bill 1/2 inch wide, not 3/8 as the others. 1 Share this post Link to post Share on other sites

peter lena 8,589 #4 Posted August 3, 2022 @ri702bill agree with you on that idler pully , like to get a matching size/ type with a larger bearing , you know where i'm going ,T/S usually has that type in stock , only have to add a 3/8 " I/D bronze bushing , for a very quiet replacement , go grease , pete 1 Share this post Link to post Share on other sites
peter lena 8,589 #5 Posted August 3, 2022 @ri702bill did over my idler pulleys , grease change and bushing , they are so solid and smooth , its like no effort in the clutch use, pete Share this post Link to post Share on other sites

Above advice assumes you have the stock engine position and PTO pulley size, of course! Looks good, keep the pictures coming. Share this post Link to post Share on other sites
