ATHENA Engine Oil Seal Kit for HONDA XR 400 1996-2004

On HONDA XR 400 from 1996 to 2004, the ATHENA P400210400047 engine oil seal kit fits in place of the original part. Every shaft that passes through the crankcase runs in an oil seal. Over time the lip hardens and oil escapes; on a two-stroke, a leak on the crankshaft side upsets the carburation.

Fitting tips

1. Drive out the old seal without scratching its housing.
