FAQ

Does this replace AM125082 and AM126710?

Yes, on compatible applications matching the listed dimensions, connector and mounting configuration. Check the original clutch number before ordering.

Will it fit a 1-inch crankshaft?

No. This clutch requires a 1-1/8-inch crankshaft. Measure the shaft if the engine has been replaced or the original clutch number is unreadable.

Does this fit every F510 or F525?

No. The F510 serial range and F525 crankshaft size matter. Verify the installed clutch and machine configuration, especially after an engine swap or previous repair.
