NOTE: (1) Apply lubricant (i.e. white zinc B dissolved into spindle oil) to bolts and nuts to stabilize their friction
coefficients.
(2) Make sure bolt and nut threads are clean before installing.
(3) Apply Loctite to threads of engine cushion rubber mounting bolts, lower roller mounting bolts, and
swing-post vertical-pin mounting bolts before installing them.
