Laser Alignment Tool
With our Laser Alignment Tool, you can quickly align drive
components to improve efficiency and reduce costly
maintenance. Much easier to use than a straight edge, it
attaches in seconds. When the highly-visible sight line lies
within the target openings, the pulley/sprockets are aligned.
10. Identify correct belt
Always select belts to match sheave grooves.
11. Matching belts
Matching multiple belts is not necessary for most Poly-V®
belt drives. If you encounter a special application calling for
matching, specify “matched belts” on the order.
12. How to install belts
After you correctly install and align the sheaves, you can
install the belts.
Always move the drive unit so you can easily slip the belts into
the grooves without force.
Never force belts into a sheave with a tool such as a
screwdriver or a wedge. Doing so may damage the ribs or
break the cords.
Refer to Table 15 (on page 30) to determine if enough
clearance exists for belt installation and take-up.
