Chain adjustert roller wheel for BTK 20424Z0010 and BDM 70400, & 20581.  Wheel only;  does not include bolt, nut, spacer, or chain adjuster.  Replaces the old roller, Capitol FI.875 0750.  The bolt hole is 3/8". 

Will probably replace Murray 680086 chain adjuster idler roller on GT60101X92 karts and others, but we haven't tried it.

Your adjuster should have a spacer to keep the wheel in the proper position.  The outside should be held on with a flat washer and a 3/8" bolt (not included).

We only stock 1, so if we get a run on them (seldom happens), it will become special-order part. Please allow an extra 15 business days for delivery. Your card will be charged as soon as the order is processed, and the order may not be cancelled or returned.
