Allis 912H - need correct belt

Recommended Posts

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?

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 For Simplicity decks, both 82" (#s 108209 & 1719819 which have been superseded to part # 1723391) and 84" (#1656960) are used on 42" decks.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.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
