Overview
The Dodge 117108 taper-lock bush is a precision shaft-locking component designed for reliable, wobble-free mounting of power transmission components. Part of Dodge’s proven taper-lock bushing line, this 3020 x 1-3/8 KW unit combines a tapered bore with an integral key system to deliver secure, repeatable engagement without the need for pullers or excessive downtime. New in box condition ensures factory integrity.
Key Features
- 8° Tapered Design: Engineered with an 8° taper and a flush-mounted design with no protruding parts providing secure locking and elimination of wobble
- Integral Key System: Available with an optional integral key in popular sizes for a more precise fit
- Precise Fit: Clearances between key and bushing are automatically eliminated, providing a more precise fit. Provides full key even in maximum bore sizes
- Easy Installation & Removal: Space required to loosen bushing using screws as jackscrews—no puller required
- Compact Flangeless Design: Dodge Taper-Lock bushings are flangeless for clean, compact application and are engineered with an 8° taper and a flush-mounted design
