Bushing pump ZF5HP19/4HP20 (OS)

Bushing pump ZF5HP19/4HP20 (OS) Width: 0.533" Housing Bore: 1.999" Shaft Dia.: 1.774" Material: Bimetal Bushing Style: Precision Normal operation of the ZF5HP19 transmission causes wear that leads to excessive bushing and shaft clearance. The Sonnax pump bushings 85916-01 and 85916-01U contain one pump bushing each to allow rebuilders to salvage pumps with damaged bushing bores. Oversized precision bushing 85916-01 allows rebuilders to salvage costly pumps with damaged bushing bores. Oversized finish-in-place bushing 85916-01U allows rebuilder to salvage pumps with damaged bushing bores, and set clearance with converter hub. Tightly toleranced, bimetal. NOTE: Bushings are oversized precision bushings for damaged pump housings. The pump-housing bushing-bore ID will require machining. This ID will have to be machined to 1.9992 +/- .0005 (50.780mm +/- 0.013mm).
