Good To Know

Q: Does this gasket come with the cover? A: No, this listing is for the gasket only and does not include the timing drive cover itself. Reuse or replace the cover separately.

Q: Should I replace this gasket every time the cover is removed? A: It is good practice to fit a new gasket any time the cover is taken off, since old gaskets can harden and leak. Confirm the part number matches your machine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
