2.1.2 Reassembly of Thrust Base to LB Subassembly
See Figure 1.3 for the following steps.
Step 1
If required, place the pilot spacer (#16-16) into the top of the anti-rotation base (#1) pilot ID.
NOTE: The pilot spacer in this location is only required if using an MSS thrust base assembly. When using an ISO thrust
base assembly, the pilot spacer is not required.
Step 2
Place gasket (#6) over the shaft and place onto the top of the anti-rotation base. Place the thrust base assembly over
top of the threads of the shaft, and turn the thrust base on by threading the thrust nut to the shaft until seated on the
anti-rotation base and gasket, making sure the gasket and thrust base are centered on the anti-rotation base.
Step 3
Insert the four mounting screws (#4) thru the anti-rotation base into the thrust base and tighten.
QXM, MX-05 and MX-10, M10 or 3/8-16 screw tighten to 18–20 Ft-LBS/24–27 Nm.
MX-20 and MX-40, M16 or 5/8-11 screw tighten to 95–100 Ft-LBS/129–135 Nm.
2.1.3 Reassembly of Optional FA/EN (F) Base to LB Subassembly
See Figures 1.2, 2.1 and 2.2 for the following steps.
Step 1
Slide the optional FA/EN (F) base (#10) over the shaft and bellows boot aligning to anti-rotation base, and insert the four
mounting screws (#11) thru the optional base holes and tighten to the anti-rotation base (#1).
QXM, MX-05 and MX-10, M10 screws tighten to 18–20 Ft-LBS/24–27 Nm.
MX-20 and MX-40, M16 screws tighten to 95–100 Ft-LBS/129–135 Nm.
