STEP 6
NOTE: Lightly lubricate quad rings/o-rings before
remounting subassemblies.
Fit the handwheel adapter assembly (#12) into the top of
the actuator housing. Slowly rotate the assembly as it ap-
proaches its lower position in the actuator; this will allow
the quad ring (#12-3) to ease over the end of the drive
sleeve avoiding damage to the quad ring.
STEP 7 (MX-20 & 40 ONLY)
Place o-ring (#12-4) around handwheel adapter; pressing
the o-ring into the slot between the handwheel adapter
assembly (#12) and the actuator housing (approximately
every 15˚ to 30˚ until o-ring seats into slot).
