WARNING: PRECAUTION NOTE
The MX-10 through MX-140 requires precaution to prevent damage to the
1-32
declutch latch. This applies while installing the handwheel adapter/gear
assembly (#1-35), retainer plate (#1-32) and screws (#1-33). If the unit is in the
clutched position (handwheel operation) during assembly, a lug-to-lug
condition can result between the clutch and the handwheel adapter/gear.
In this situation the latch will be compressed and damaged when the plate
screws are tightened.
Assure the clutch lugs are fully engaged to the bronze gear lugs before
installing the handwheel adapter/gear assembly. The latch must be rotated
down and not holding the clutch off the bronze worm gear. When installing the
handwheel adapter/gear, ensure these lugs fall between the clutch lugs. This
position will allow the handwheel adapter/gear lugs to be fully engaged to the
clutch lugs. The final step is to install the retaining plate and socket head cap
screws.
Place the retainer plate (#1-32) on the top of the actuator housing.
Align the mounting taps, and secure with screws (#1-33).
STEP 9 (MX-10, 20 & 40)
Install handwheel (#1-8) onto handwheel adapter assembly (#12),
9
align the handwheel with screw holes and tighten the 4 socket head
cap screws (#1-11).
or
Install side-mounted handwheel (subassembly #13) according to
remounting instructions detailed in Section 4.4.2.
