Good To Know

Q: Is it necessary to swap this gasket when the throttle body comes off? A: Yes, gaskets are generally single-use, and a reused or damaged gasket can leak air. Installing a fresh one during reassembly protects the seal.

Q: Will this gasket work on other 1503-equipped models? A: Compatibility depends on the exact model and year, so verify your machine and part number against 420950792 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.
