NOTE: Perform the operation on one cylinder at a time. Do not turn the engine until pushrod adjustments have been completed.
CAUTION
Turning the engine while valve is held o the seat could result in valve to valve contact or valve to piston contact, serious valve train
damage could occur.

NOTES:
Shortening pushrod adjuster an additional six ats or one full turn from zero lash often results ion quieter pushrod operation. This provides additional

travel for the hydraulic piston assembly, which can improve he ability of the hydraulic unit to maintain zero lash under normal operating conditions.
Lifters for Harley-Davidson® Twin Cam 88® engines require HL

NOTES:
After a few hundred miles it is a good idea to recheck pushrod adjustment in a new engine as valve train may tighten up due to gasket compression and

valve seat wear.

T equipped lifters may be somewhat noisy for 10-20 miles. If lifters are still noisy after 20 miles it is
recommended that the pushrods be adjusted ½ turns looser.

NOTE: Engine may require several miles at normal operating temperature for lifters to ll with oil and quiet the valve train. Our experience has shown that
lifters for Harley-Davidson® Twin Cam 88® engines are slow to ll.
