HOW TO MEASURE, ASSEMBLE & INSTALL
I. How to Measure
Pull belt tight around pulleys to check hand tight length, overlapping
the last two tabs with two holes in matching links as shown. Count the
number of links and remove one link for every 24 of 3L, O/Z, A/4L, and
B/5L sections, and one link for every 20 of C and D sections. This gives
the correct installed belt length and will ensure optimum belt tension
when running.
Note: Every tenth link is designated with an arrow (
belt has the same number of links.
IMPORTANT — Turn belt INSIDE OUT (as shown) to ensure easy assembly
and disassembly.
II. Disassembly
A. Hold belt upside down. Bend back as far as possible; hold with one hand.
Twist one tab 90° parallel with slot.
B. Pull end of link over tab.
C. Rotate belt end with tab 90°.
D. Pull belt end through two links.

III. Assembly
A. Hold belt with tabs pointing outward.
B. Place end tab through two links at once.
C. Flex belt further and insert second tab through end link by twisting tab with thumb.
D. Ensure tab returns to position across belt. Reverse belt so tabs run inside.

IV. Installation
1. Turn belt with tabs to the inside before installing.
2. Determine direction of drive rotation.
3. Align belt directional arrow (
4. Fit belt in nearest groove of smaller pulley.
5. Roll belt onto larger pulley, turning the drive slowly. Belt may seem very tight; this is ok;
DO NOT JOG MOTOR.
6. Check to see all tabs are still in their correct position and are not twisted out of alignment.
7. For multiple belt drives, work belt from groove to groove. On particularly wide drives, it may
be easier to install half the belts from the inboard side and half from the outboard.
Note: With drive ratios around 1:1, it may be necessary to add back one link to allow belts to be
rolled on. This does not apply if using the Alternative Installation Method.
V. Alternative Installation Method
1. Set motor to mid-position of adjustment range and mark base clearly.
2. Determine required belt length as in I.
3. Push motor forward to minimum centre distance.
4. Install belts as in IV.
5. Pull motor back to previously marked mid-position.
VI. Retensioning
Like all high performance V-belts, PowerTwist Plus V-Belts require the maintenance of correct
drive tension to operate efficiently. Experience indicates that drive tension should be checked
after 24 hours running at full load. A retension may be necessary depending on the severity of
the drive. Any initial belt stretch is then taken up. Subsequently, belt tension should be checked
periodically and adjusted
when necessary.
