Installation Notes and Tips

Verify the housing bore and outside diameter before installation to confirm the seal matches the engine opening. Clean the sealing surface thoroughly and inspect the camshaft end area for wear, scoring, or debris that could affect sealing. Confirm rear-position application and compare the old seal to part number 710861 before installation.
