(A) These fits are either shrink fits controlled by machining, fits that mayreadily be adjusted, or fits where wear does not normally occur. In each
case, the fit must be held to manufacturing tolerance.
(B) Side clearance with piston. on piston rings must be measured with face of ring flush
(C) Replacements to correct these items must be made to give uniform backlash within 0.001 between the stationary gear and pinions, and within 0.001 between the pinions and the ring gear.
(D) These dimensions shown angles to piston pin. are measured at bottom of piston skirt at right
(E) Permissible wear of the crankshaft (rod and main bearing journals) to
be minus 0.0015 on the diameter.
(L) Loose fit; wherein surfaces. a definite clearance is mentioned between the mating
(T) Tight fit; shrink or interference fit.
