How do you align a car pulley?
How to align the pulley?
- Remove the belt (see How to replace a belt).
- Loosen the driven pulley (shaft pulley), and adjust up and down to obtain level.
- Firmly re-tighten the pulley.
- Re-install and re-adjust the belt.
What is offset pulley misalignment?
Pulley misalignment can be angular, between the driving and driven pulley in either the vertical or horizontal plane, or it can be parallel, with one pulley offset from the other as the pulleys are viewed from the edge. In practice, more than one type of belt misalignment can exist at the same time.
How do pulleys get misaligned?
Angular Misalignment This occurs when pulleys become “tilted” because their shafts are not parallel. Worn bushings and bearings can allow rotating shafts to become cockeyed in their bores. Premature bearing and bushing wear is often caused by the strain of excessive belt tension.
What do you need to know about pulley alignment?
This guide provides information for the implementation of good pulley alignment of belt-driven equipment including terminology, alignment methods as well as belt maintenance, storage and tensioning. The content of this guide and our 5-Step Sheave/Pulley Alignment Procedure are basic guides to re-align machines.
Why are laser pulleys used for sheave alignment?
Laser pulley alignment systems are now well established in the sheave alignment field, and have proven themselves in greatly reducing downtime and the manpower needed to do the alignment, while simultaneously achieving far greater accuracy. This results in significant labor savings and increased production uptime.

What are the forces that work on a pulley?
The forces that work during operation are not uniform around the entire belt length; there is always a tight side tension and a slack side tension. The difference between these tensions is often called by belt manufacturers the effective or net pull. This effective pull is applied at the rim of the pulley and is the force that produces work.
