SHAFT ASSEMBLY Replacing shrunk fit components can be costly. Complete shaft assemblies reduce installation costs. Split to bolt sprockets reduce future maintenance costs. MOUNTING METHODS: • Finished bore - Slip-Fit & Heat Shrunk • Split-Taper, Taper-Lock & QD Bushing • Split to Bolt • Idler Sprockets (Bearing/Urethane/Bronze/Other) • Keyless locking (e.g. Power-Lock) • Bearing Installation

For ease of installation XTB type bushings are suggested for double hub construction
* Split Taper bushings are standard for single style hubs.
