2.1.5 LB Lubrication
Step 1
Thrust base assembly (#5) lubrication.
Using only Mobil SHC 220 Mobilith grease, fill thrust base thru the grease fitting (#10-11) until grease is forced out of
the relief fitting.
Step 2
Anti-rotation base assembly lubrication.
Remove pipe plug (#9). Using only Mobil SHC 220 Mobilith grease fill anti-rotation base assembly thru the grease
fitting (#8) until grease is forced out of the pipe plug hole. Replace pipe plug.
NOTES:
1. Do not over-fill. It is best to fill the anti-rotation base assembly in the open position (stem retracted). If over-filled,
grease will be forced out when operating unit.
2. Grease at intervals of 2000 open-closed cycles and adjust depending on load profile.
2.1.6 Reassembly of QXM or MX Actuators to LB/Thrust Base Assembly
See Figure 1.1 for the following steps.
Step 1
Slide gasket (#5) or over shaft and place on top of LB thrust base. If required (QXM units with MSS base only), place
spacer pilot (#16-16) into LB thrust base pilot ID.
Step 2
Place unit actuator on top of LB subassembly and align actuator lugs, pilot and with LB thrust base lugs and pilot.
Check to make sure gasket is also aligned. Rotate actuator and gasket to align mounting holes.
Step 3
Insert mounting bolts (#5) thru thrust base and tighten to actuator.
MX-05, M10 or 3/8-16 screws, tighten to 10–12 Ft-LBS/13–16 Nm.
QXM and MX-10 M8 screws, tighten to 8–10 Ft-LBS/11–13 Nm.
MX-20 and MX-40 M12 screws, tighten to 17–20 Ft-LBS/23–27 Nm.
