4.12.4 MX-85, -140, and -150 Optional Drive Sleeve
and Baseplate Remounting
STEP 1
Assemble drive sleeve assembly with drive sleeve lying on opposite end of lugs. Place worm gear
(#2-2), key (#2-6) and encoder drive gear (#2-3) onto the drive sleeve (#2-1). Place the ball bearing
(#2-4) into the baseplate assembly. See picture 4b in Section 4.12.3.
Lightly lubricate the bottom of the drive sleeve (#2-1) and the baseplate seal (#11-3).
Lift the drive sleeve assembly up, and holding the encoder drive gear (#2-2), turn the drive sleeve
over and place into the baseplate assembly. See picture 4a in Section 4.12.3.
STEP 2
With help, lift housing and place over the drive sleeve and baseplate assemblies. Match up the
mounting holes in the baseplate and housing. With the actuator sitting on the baseplate, slide the
unit over to the edge and mount one or two of the baseplate screws (#11-5). Turn unit over on its
side with the drive sleeve horizontal and secure the baseplate with the rest of the mounting screws.
NOTE: The drive sleeve is held in from the top by the handwheel worm gear. Without the handwheel
worm gear, the drive sleeve may slip out of position. Push the drive sleeve back into position from
the handwheel worm gear end. See pictures 3, 2, and 1, in that order, from Section 4.12.1.
