About This Product

MCS transmission mainshaft bearing housing. It replaces OEM 35100-79. It fits 1980 to 1986 4-speed Big Twin models. This housing locates the mainshaft bearing and keeps the shaft aligned under load. Fit it if your original has a spun bearing bore or cracked casting. You will need this for any serious 4-speed rebuild on a late Shovelhead or early Evolution bike.

Manufacturer part number: 904275.
