716156 : Pilot Bushing .670 ID X 1.818 OD (#716156)

Retail Price: $25.27


The 716156 pilot bushing is one of the most popular pilot bushings offered by Advance Adapters. The 716156 pilot bushing is an essential component for an AMC to Ford transmission conversion. Many Jeep owners who are upgrading from a T150 or T176 soon realize the factory AMC bellhousing will bolt up to a Ford Transmission like a T18 or NP435. Because of the shorter 6-1/2” Ford input shaft coupled with a .670” pilot tip, the factory pilot bushing supplied for the original Jeep transmission will not work. A small overlooked item and yet critical to the actual conversion itself. Many jeep owners will spend countless hours searching for the proper factory AMC pilot bushing. Their unsuccessful searches are actually quite valid, as there was not a factory pilot bushing offered by Jeep that will offer the required dimensions for a Ford input shaft.


Advance Adapters designed this special pilot bushing to solve the issue. The pilot bushing is manufactured of a special bronze oilite material. It is essentially a bronze alloy material that has be penetrated with oil. The bushing essentially has “pores” where oil can permeate throughout the bushing keeping the bushing properly lubricated for the transmission input shaft.


The dimensions of the 716156 pilot bushing are:
O.D X I.D. X LENGTH
1.818” X .670” X .50”

The O.D. dimension of the 716156 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 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. It should also be noted there are other transmissions that share the .67” diameter as used by ford; therefore, the 716156 is not necessarily a AMC/Ford only application.

AMC to Ford Bushing

This bushing that is required to be used with the new adapter for the Ford T-18 to Model 20 TC in my jeep got here and is to be used as a spare one if needed down the road. It seems to be Ok, I do question when I bought my new kit from you all (direct for the change over) it said all parts included. The pilot bushing was not in kit and I had to get it from the Off road center that did the change over . Alot higher than the one from you but same package ect (came from you) Why was this not included?? if it said all required parts?? Thank you
