Sears Craftsman Garage Door Opener Gear-Shaft Assembly

    Offered for Sale is this Sears Craftsman / Chamberlain Garage Door Operator Replacement Gear and Shaft Assembly, NEW.  Included in the kit is the assembly, a tube of grease, a hard-plastic worm drive gear, a bearing kit, and instructions.

    This assembly has been used on virtually every Chamberlain product - Sears Craftsman, Tru-Value, Master Mechanic, Monark, Chamberlain, some Wayne Dalton, current Raynor, AccessMaster, Builder's Mark and Liftmaster - since the mid 1980's.  This will replace the sprocket and gear assembly on every chain and cable, or all-chain drive operator, with the following exceptions:  it will NOT work on any operator that has a "dual sprocket" on the top for slow-speed operation capability, not on any DC powered operator, not on any screw-drive or belt-drive operators.  This is the standard Chamberlain replacement assembly/kit.  If what you need looks like this, then this WILL work.
