CRANK CASE PREPARATION
Tools Required:
__ Flat Blade Screwdriver
__ Rubber Mallet
__ Fine File
__ White Lithium Grease
Parts Required:
__ Engine Case
__ 8mm Head Stud Kit, ACV-P01-86
__ Case kit, ACV-P02-12
__ Main Bearing Dowel Pins (Set of 5), ACV-P01-46
__ Valve Lifters, ACV-P01-48
__ Main Bearing Set (split bearings only), ACV-P01-57
__ Cam Bearings, ACV-P01-58
__ Gasket Set, ACV-P02-15
Preparation:
__ 1. Separate the case halves and thoroughly clean them
with mineral spirits.
Remove all traces of metal chips
and dust from the case.
Pay particular attention to
removing metal chips which still cling to the edge of
machined surfaces (see photo) and to casting slag on the
inside of the case which may dislodge after the engine
is in service.
Assembly Instructions:
__1. Install the head studs as shown in the photos below.
__2. If you are painting the case, now is the best time to do
so. Mask off all machined surfaces, mating surfaces,
and holes before painting.
Note: We have had good luck using "Barbecue Black"
spray paint on the case and piston barrels.
