FORD F2 BRAKE PARTS
Ford 3/4 Ton brake correction
There is a mistake in the factory Ford parts manual. The clevis pin for the brake pedal is listed incorrectly. In the Ford parts manual 92y2489 is listed for all models, C, D, Y, J. It also lists this pin as 1/2" dia. In actuallity it measures .374. The correct clevis for larger trucks is 91t2489. 91t is the prefix for the larger truck parts, notice the brake pushrod for the larger trucks is 91t2143-a. It is listed for only larger trucks, not 1/2 ton. LMC lists this pushrod for F2 only and that is correct. THe correct pin size and hole in pushrod for the larger F2 truck is .435".
