Louofm1 0 Posted July 25, 2010 Hello experts :) I have a Allis Chalmers 912 (I believe equivalent is Simplicity 7112). The tractor was built in 1982 or 1983 and I recently aquired it. It has the 42" deck ....everything works great. The belt in the deck (that drives the 3 blades) broke. I need to obtain a replacement and need to verify the correct size. Im not 100% sure but believe it is: Simplicity # 1719819 Application:Spindle Length:82" Width:1/2" Can someone please verify this application? Share this post Link to post Share on other sites
yukon 331 Posted July 26, 2010 i went on partstree.com and looked up a 912h with a 42 inch deck and found the number 1656960 for the deck belt hope that helps you Share this post Link to post Share on other sites
Louofm1 0 Posted July 26, 2010 i just want to make sure i get the correct belts. Is this part the "deck belt" that drives the deck (engine to deck)? I need the belt "inside" the deck (that turns the three blades). Share this post Link to post Share on other sites
PhanDad 3,248 Posted July 26, 2010 On your 912, is there a decal under the hood listing part numbers for commonly replaced parts? That's the best reference if the tractor and deck are original. For Simplicity decks, both 82" (#s 108209 & 1719819 which have been superseded to part # 1723391) and 84" (#1656960) are used on 42" decks. The 82" belts were used on older decks such as mfg #990784 & #1690252. The 84" belts are used on newer decks such as mfg #1690501 (flat blades) and #1691215 (gull wing blades). You can always take a piece of rope and thread it around all the pulleys and measure the required length. Share this post Link to post Share on other sites
