Timing Components: Service and Repair

STANDARD PROCEDURE - VALVE TIMING VERIFICATION
1) Remove front cylinder head cover and all 6 spark plugs.
2) Rotate engine until the #2 piston is at TDC of the compression stroke.
3) Install a degree wheel on the crankshaft pulley.
4) With proper adapter, install a dial indicator into #2 spark plug hole. Using the indicator find TDC on the compression stroke.
5) Position the degree wheel to zero.
6) Remove dial indicator from spark plug hole.
7) Place a 5.08 mm (0.200 inch) spacer between the valve stem tip of #2 intake valve and rocker arm pad. Allow tappet to bleed down to give a solid tappet effect.
8) Install a dial indicator so plunger contacts the #2 intake valve spring retainer as nearly perpendicular as possible. Zero the indicator.
9) Rotate the engine clockwise until the intake valve has lifted 0.254 mm (0.010 inch).

CAUTION: Do not turn crankshaft any further clockwise as intake valve might bottom and result in serious damage.

10) Degree wheel should read 6 degrees BTDC to 6 degrees ATDC.
