Description

4030x70mm Taper-Lock® Style Bushing, 70mm Bore, Steel

The 4030x70mm is a 4030 series Taper-Lock style bushing with a 70mm bore, machined from solid steel with a black oxide finish. It mounts any 4030-bushed component, including sheaves, sprockets, and timing pulleys, to a 70mm shaft. Every bushing is machined from solid stock, never sintered or powdered metal, which matters in a part that transmits its load through a friction fit.

Frequently Asked Questions

What does the 4030x70mm bushing fit?

It fits any sheave, sprocket, pulley, or coupling machined for a 4030 series Taper-Lock style bushing, and mounts that component to a 70mm shaft. The 4030 size is standardized across manufacturers, so the component brand does not matter.

Does the 4030x70mm replace the Dodge 4030 X 70MM bushing?

Yes. The 4030 series dimensions are an industry standard, and published interchange data crosses the 4030x70mm directly to the Dodge 4030 X 70MM, as well as Martin 4030 70MM, Gates 4030 70MM, TB Woods TL403070MM. Verify bore size before ordering.

How does a Taper-Lock style bushing install?

The bushing is split and tapered. Slide it onto the shaft, seat the component over it, and tighten the pull-up screws in the threaded holes. The screws draw the taper into the component, clamping the bushing onto the shaft. To remove, back the screws out and use them in the jacking holes to break the taper free.
