Oregon HarvesterLok Sprocket Hub (3/4" Pitch) HL1

Replacement hub for the Oregon Harvesterlok drive sprocket system. The hub attaches to the drive shaft and rim by expanding in both directions when you tighten the allen head cap screws. To replace, simply remove all allen head cap screws from locking hub, and fit one of screws in the offset holes and tighten. This will force apart the locking collar and it should slide off the motor shaft and rim.
