ALIGNING FLYWHEEL AND HOUSING

 

Proper aligning of flywheel and housing is of extreme importance as miss                                                alignment can be attributed to many vibration and problems.

1.      Mount flywheel housing to block with gasket and or thin bead of RTV.  Install four 7/16-14 x 1 1/16 cross drilled hex bolts and safety wire.  Note if any flywheel housing bolt holes in block are open into crankcase it is suggested to use a small amount of RTV on threads of bolt.  This will reduce oil leakage into flywheel housing.  

2.      Place two .010 shims, I under each of the two mounting lugs on top of flywheel housing and install bolts and tighten.

3.      Mount indicator on rear of crankshaft and measure around diameter of flywheel housing.  Adjust by adding or subtracting shims.  Recheck measurement.  Less than .010 is desired not always obtainable left to right.

4.      Mount flywheel to crankshaft with four 7/16-20x 13/16 cross drilled hex bolts and dowel pin retainer.  Using too long of bolts can cause severe damage to engine.  Tighten bolts do not install safety wire or pilot bearing.

5.      Mount indicator on flywheel housing and measure run out near outer edge of clutch surface.  Adjust by loosing flywheel bolts and pry flywheel from crankshaft.  Install shim between crankshaft and flywheel where necessary.  Tighten bolts and recheck measurement.  This should be less then .005

6.      Install safety wire and pilot bearing.
