Installation Notes

Verify crankshaft journal size, housing bore, and oil clearance before installation. This part is a standard-size bearing, so it should be matched to the engine’s measured dimensions rather than assumed from model year alone. Confirm the application notes for oil-hole removal and use proper assembly lubrication and torque procedures during engine rebuild service. Fits 1969-1973 Ford Mustang, N/A; Fits 1977-1996 Ford F-150, N/A; Fits 1983-1989 Mercury Grand Marquis, N/A.
