MV Displacement Limiters

Variable Motor Displacement Limiters
1. Remove the tamper-resistant cap from the displace-
ment limiter. Measure and note the length of the
adjustment screw up to the seal lock nut. Using a
19 mm hex wrench, loosen the seal lock nut and
remove the nut. Remove the limiter screw from the
motor housing with a 6 mm internal hex wrench.
2. Install the limiter screw with the noted length between
adjustment screw and the seal lock nut. Do not install
a new tamper-resistant cap until the limiter has been
adjusted.
3. Final adjustment of the displacement limiters should
be performed on a test stand.
Do not turn the limiter screws counterclockwise
beyond their initial adjustment positions.
One full turn of the displacement limiter adjustment
screw will change the displacement as follows:

4. Following the final adjustment, install new tamper
resistant caps.
Caution
Care should be taken in adjusting displacement
limiters to avoid undesirable speed conditions. The
seal lock nut must be retorqued after every
adjustment to prevent an unexpected change in
operating conditions and to prevent external leakage
during unit operation.
