travisg84 1 #1 Posted August 3, 2009 I've got a a 42" sd deck that was "seized up" when I bought it. After I got it home and pulled the cover off and cleaned it up and got it spinning. Then I decided to throw it under my 312 and see just how bad the bearings were, it spun fine for about 10 seconds and I found out how bad the deck belt was (I think there are pieces of the belt in my neighbors yard . My question is there is no idenification on the deck as to what year it is, the tensioner set up is different from my other deck which is an 87. It still is attach-a-matic of course. Do all the of those style decks use the same length belts? Share this post Link to post Share on other sites
tarcoleo 119 #2 Posted August 3, 2009 Don't know about all 42" decks. You can find out what length belt you need for your new deck with a length of rope looped around all the sheaves and measuring length of same. The trick is that the rope, depending on its size, may not ride in the sheaves to the exact same depth as the belt. Therefore, with your other mounted deck, measure the length with the same size rope on that deck and determine any correction between the rope's measured length and the length of the proper belt which you have and already know. Apply that correction factor to the new deck. Its a little involved but it works-- it did for me anyway. swamp yankee :thumbs2: Share this post Link to post Share on other sites
mcwh1950 2 #3 Posted August 4, 2009 travis take the belt off of the other 42" deck and see if it fit this deck i think the belt should be about 86 inch long. Share this post Link to post Share on other sites
tarcoleo 119 #4 Posted August 4, 2009 Why didn't I think of that? The procedure is still a good one in other instances. swamp yankee Share this post Link to post Share on other sites
travisg84 1 #5 Posted August 4, 2009 I didn't think of it either. I'll get out there one day after work and take a look. Share this post Link to post Share on other sites
