Advance Adapters Pilot Bearing .750" ID X 1.818" OD

The 716164 is a pilot bushing for adapting AMC engines to some transmissions with a .75" pilot tip. The bushing is supplied in several of our adapter kits including our AMC to NV3550 bellhousing. The pilot bushing is also commonly sought after for a conversion like an AMC to late model AX15 where the factory OEM pilot bushing does not fit some AMC cranks.

The dimensions of the 716164 pilot bushing are: O.D X I.D. X Length 1.818" X .75" X .50".

The O.D. dimension of the 716164 is clearly not the approximate 1" pilot crank diameter used by most AMC cranks. The larger 1.818" outside diameter is completely intentional. Since there have been numerous variations in AMC cranks over the years coupled with the introduction of "crank sleeves" used on some inline 6 applications, we have chose to use the outer diameter portion of the AMC crank. This outer step is an area on AMC cranks that is almost always uniform on AMC blocks over a 30 year period. By using this outer step, the variations of the inner crank do not have any factor to the fitment of the bushing.
