INSTALLATION


(2) Make sure tops of cylinders and cylinder head faces are clean. Apply a light coat of engine oil or grease to both sides of gaskets and install gaskets.

(3) Place heads on cylinders and install heavy washers and head bolts. Attach cylinder he2d bracket (top mounting bracket) with the two long bolts, spacers and flat washers. Spacers go between the cylinder heads and bracket. A flat washer goes under the head of each long bolt above bracket. Some engines have flat washers between spacers and bracket.

(4) Secure engine top mounting bracket (cylinder head bracket) to frame lug. installing required number of thin shim washers, together with clamp for front spark plug cable, to fill space between bracket and frame lug before tightening bolt. NOTE: Frame lug must be free from paint or grease to make clean electrical connection with plated shim washers and mounting bracket for adequate radio bonding.

(5) Head bolts must be tightened evenly to attain a tight joint. First turn bolts down just snug; then tighten each of them one-eighth to one-quarter turn at a time until all are securely tightened. Use special head bolt wrench (41-W-1525). If torque wrench is available, tighten head bolts to 60 foot-pounds minimum, 65 foot-pounds maximum tension when engine is cold.

(6) Install spark plugs (use new gaskets if old ones are in bad condition) and tighten securely. Attach the high tension cable terminals.
