This complete procedure will take approximately 90 minutes.
Required Tools:
5/16” Socket Wrench

9/16” Socket Wrench
5/16” Nut Driver
Bungee Cord (or equivalent)
Standard Screwdriver
Large Snap Ring Pliers
1/4” Hex Allen Wrench
Small Standard Screwdriver
Hammer
Side Cutters
1/4” Open End Wrench

3/16” Hex Allen Socket Wrench (w/approx. 6” ext.)
CAUTION
After service has been completed on the lift housing, the inner and outer screws must be ”timed”. If this timing
measurement is not equally maintained between the two lift drive screws, the drive screws will not move up
equally, and damage to the bed’s moving parts could result. Refer to step 10 for proper timing procedure.
1. Unplug the power cord from the wall socket. Remove lower lift cover (see page 67).
2. Remove lift motor and capacitor (see page 77).
3. Remove lift housing (see page 81 & 82).
4. Using a 1/4” hex allen wrench, remove the four screws (K) and lock washers holding the housing cap (A)
to the lift housing ( lock washers not shown).
5. Lift up on the housing cap to remove it and set it aside. Note the position of the washers before they are
disturbed. Some washers may stick to the housing cap as it is removed.
6. If the guide bushings (B) need to be replaced, push them out of the housing cap from the top.
LIFT GEAR REPLACEMENT
CAUTION
Take note of the proper washer arrangement for re–assembly (see illustration #2) or damage to the unit could
occur.
7. To replace gears (C), lift straight up on the defective gear(s) to remove. Idler gear (D) can be removed
by lifting it straight up and off the lift housing. To remove motor pinion gear (E) and manual idler gear (F),
first use a 3/8” socket to remove the four fiber nuts holding the isolation plate to the lift housing. Pull straight
down on the motor coupler to remove it. To remove motor pinion gear (E), remove the snap ring from
underneath and pull the gear and shaft assembly out of the lift housing. To remove manual idler gear (F),
use a 3/16” punch and hammer to remove the roll pin securing the gear shaft to the manual hex shaft cou-
pler and pull the gear and shaft assembly out of the lift housing.
NOTE
New gears will be provided in a kit containing the gear with the attached shaft, appropriate spring washers,
thrust bearings, timing plate and grease. Be sure to apply grease generously to all gears whenever new
gears are installed.
