Valve Springs: Removal
- Remove rocker arm cover and spark plug on cylinder to be serviced. Be sure piston is at top of stroke with both valves closed. Install air line with adapter in spark plug hole.NOTE: If air pressure fails to hold valve closed, remove cylinder head for inspection of valve seat.
- Remove required rocker arms and push rods. Use suitable spring compression tool (T62F-6565-A or 6513-HH) to compress valve and remove retainer locks, sleeve, spring retainer and valve spring. Remove and discard valve stem seal. Do not remove air pressure as this will allow valve to fall into cylinder if piston has been forced to bottom of cylinder.
