Valve Guide Replacement

Replacement

Valve Guide
1. Using the SST(09221-3F100A), withdraw the old valve guide toward the bottom of cylinder head.




2. Recondition the valve guide hole so that it can match the newly press-fitted oversize valve guide.
3. Using the SST(09221-3F100A/B), press-fit the valve guide. The valve guide must be press-fitted from the upper side of the cylinder head. Keep in mind that the intake and exhaust valve guides are different in length.






Valve guide length
Intake : 46mm (1.8in.)
Exhaust : 54.5mm (2.15in.)






NOTE:
Before the valve guide is press-fitted using the SST (09221-3F100A/B), remove the valve spring seat to install the valve guide correctly.

4. After the valve guide is press-fitted, insert a new valve and check for proper stem -to-guide clearance.
5. After the valve guide is replaced, check that the valve is seated properly. Recondition the valve seats as necessary.
