These are the two-screw flanged bushings that go into the bushed AK, BK, 2AK and 2BK sheave families and small bushed sprockets. The 4 degree tapered bore draws the bushing down onto the shaft as the two cap screws are tightened, giving a concentric, backlash-free grip that comes apart again without a puller.\u003c\/p\u003e\n\u003cp\u003eThree stock bores are listed here: 1 in. (Dodge 122053), 1-1\/8 in. (Dodge 122054) and 1-3\/8 in. (Dodge 121145).

They are also not Taper-Lock bushings, despite a number of catalogs listing them that way; Taper-Lock is a separate keyless-flange line (1008, 1108, 1210, 1610 and so on).\u003c\/p\u003e\n\u003cp\u003eCross references for the same bushing from other makers: Maska HX1, Martin H 1, TB Wood's QT1, Gates QT 1, Carlisle H-1, Browning and Regal H 1.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eWipe the taper and the bore clean and dry. Do not use anti-seize, oil or any lubricant on the mating taper surfaces, which would cause the bushing to over-advance and crack the hub. Align the keyways, start both cap screws evenly, then tighten alternately to 90 lb-in. Recheck the torque after a few hours of running.\u003c\/p\u003e\n\u003cp\u003eNot sure which bushing your sheave is bored for?
