(2) Remove gasoline tank and oil tank (par. [107]).
(3) Remove cylinder head bracket to frame lug bolt: this will free clamp which secures front spark plug cable. Pay particular attention to shim washers placed between cylinder head bracket and frame lug, as these washers must be replaced when installing cylinder head.
(4) Remove spark plug, or plugs.
(5) Remove cylinder head bolts, using head bolt wrench 41–W–1525. NOTE: On some 42 WLA models, plain washers (0.095–inch thick), in addition to regular (heavy) cylinder head bolt washers, were used to prevent cylinder head bolts from bottoming.
(6) Perform carbon removal (head only). Refer to paragraph [42].
b. Installing Gasket and Head ([fig. 15]).
(1) Clean top of cylinder. Apply a light application of grease or oil to both sides of gasket before locating on cylinder head. Place head on cylinder.
(2) Install head bolts, using heavy washers (also 0.095–inch thick plain washers, if any were removed). If in doubt as to use of 0.095–inch thick washers in addition to regular washers, measure depth of bolt holes in cylinder head. Head having hole depth of 31/32 inch must use the 0.095–inch thick washers in addition to regular washers. Head having bolt hole depth of 11⁄16 inch does not require the 0.095–inch thick washers.
(3) Install cylinder frame bracket with the two long bolts, special (spool‐shaped) spacers, and flat washers. The spacers go between cylinder heads and frame bracket. A flat washer goes under the head of each long cylinder bolt, above the bracket; some engines may have flat washers between the spacers and the bracket.
