V-Belt
INSTALLATION GUIDE
CHECK ALIGNMENT
Proper alignment is essential for long V-belt life. Check belt
alignment whenever you maintain or replace belts or whenever
you remove or install sheaves. Limit misalignment to 1/2 degree or
approximately 1/10" per foot of center distance.
The illustration above shows the correct way to check alignment
between two sheaves with a straight edge. Check both front and
back alignment. Straight edge should touch sheaves at the four
points indicated.
Non-parallel shafts or sheaves not aligned axially can cause
angular misalignment.
Laser Alignment Tool
With our Laser Alignment Tool, you can quickly align drive
components to improve effciency and reduce costly maintenance.
Much easier to use than a straight edge, it attaches in seconds
and when the highly visible sight line lies within the target
openings, the pulley/sprockets are aligned.
IDENTIFY CORRECT BELT
Always select belts to match sheave grooves. Use a sheave groove
gauge to determine the proper belt cross section. (Fig. A).
Use a belt gauge to verify the old belt cross section when belt
identifcation is no longer legible. (Fig. B).
MATCHING BELTS
When using multiple grooved sheaves, be sure that all of the
belts are the same brand. Always replace complete sets of
V-Belts even if only one is worn or damaged.
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.
