Some engines have both standard and .010 inch oversize valve lifters. The .010 inch oversize valve lifters are etched with a ``0'' on the side of the lifter. Also, the cylinder block will be marked if an oversize lifter is used, Fig. 22.
1. Remove intake manifold as outlined previously.
2. Remove valve covers, rocker arm assemblies and push rods. Note location of valve train components so they can be installed in original position.
3. Remove hydraulic lifter retainer bolts, then retainer, Fig. 23.
4. Remove valve lifters, then disassemble, Fig. 24.
5. If plunger and body appear satisfactory, blow off air to remove all particles of dirt. Install the plunger in the body without other parts and check for free movement. A simple test is to be sure that the plunger will drop of its own weight in the body, Fig. 24.
6. Reverse procedure to install. Before installation, prime new or reassembled lifters by working lifter plunger while submerged in kerosene or diesel fuel. Lifter could be damaged if installed dry when starting engine. When assembling lifters, do not interchange plungers, as they are specifically fitted to the bodies during manufacture.
