Special Information
Hydraulic valve lifters require little attention. These lifters are extremely simple in design. Normally, adjustments are not
necessary and servicing requires only that care and cleanliness be exercised in the handling of parts.
Removal
IMPORTANT: Organize and store the rocker arm assemblies, pushrods, and valve lifters in matched sets for assembly and
installation in their original locations.
