Hydraulic Lifter Service

Two types of lifters are used. They are interchangeable as complete assemblies, but their parts are not interchangeable. Type A has a groove near its base which type B lacks. Type B uses an inertia valve and retainer which should be removed from the push rod seat. To check type B, shake the push rod seat and inertia valve assembly and the valve should move. Lifters are serviced as assemblies. CAUTION - Do not pump lifter assembly during leakdown test.
