Cylinder head and Piston Disassembly

Cylinder head disassembly

1. Remove the valve lifters and pads. Be careful not to scratch the lifter bodies or lifter bores in the cylinder head. Be very careful to identify each lifters position so that it may be returned to its original place.

NOTE:
Deburr any deformed valve stem end. Use an oil stone to smooth the stem end. This will help prevent damage to the valve guide during valve removal.

4. Use a small box to hold the parts and identify the original position of each lifter and valve. Be very careful not to mix the location of these components.

C. Piston

1.    Make each piston to aid in reassembly.

2.    Place a clean towel or rag into the crank-case to keep circlips and material from falling into the engine.

3. Remove piston pin clips, piston pins, and pistons.
