Refer to Figure 5-27. 4. With valve spring keepers (1) removed, remove upper washer (2), valve spring (3), oil seal (4), lower washer (Roto-Coil) (5) and valve (6).
Replaces
After removing the valve springs, removal of the existing valve stem seals can be accomplished easily and quickly by using the J 39460 Valve Stem Seal Removal tool. Failure to use this tool could make seal removal more difficult, and could result in damaging the outside diameter of the valve guides.
