CAUTION: Do not rous€ the thrust lhim and tho 79.8mm shim il tho outer rac6 was ddvon out.
NOTE;
a The bearing outer race and taper€d toller bearingshould be reDlaced as a set.a Inspect and adjust the tapered roller bearing proload
whenever th€ tapered roll€f bearing is roplac€d.
1 . Remove the oil seals from the transmission housing
and clutch housing (see page 15-13).
2. Remove the bearing outer raca, the thrust shim, andthe 79.5 mm shim from th€ transmission housing.

Opening Drag Check
(Motor Removedl
Betore installing the motor, measure the etfort required
to open the glass using a spring scale as shown.
CAUTION: When using a spring scale, protoct the
leading edg6 ot th€ glass with a shop towel.
lf load is over 40 N (4 kgt, 9lbf). check side clearance
and glass height adjustment (see page 2O-78).
Closing Force Check
(Motor Installedl
1. After installing all removed parts, have a hetper hotd
the switch to close the glass while you measure
torce required to stop it. Attach a spring scale asshown. Read the force as soon as the glass siops
moving, then immediately release the switch andspnng scare.
CAUTION: When using a spring scale, protoct tho
leading odge ol th€ glass with a shop towel.
200-290 N(20 - 30 kgf, rt4- 66 lbf)
lf the force is not within specification, install a new
lock washer, adjust the tension by turning the mo-
tor clutch adjusting nut, and bend the lock washer
against the motor clutch adjusting nut.

Connect battery power to terminal C and ground termi-
nal B, and connect a test light between terminals A and
NOTE: Use a 12 V, 3W- 18Wtest light.
Dip the A-/C thermostat into a cup filled with ice water,
and check the test light.
The light should go off at 37"F (3"C) or less. and should
come on at 39"F (4"C1 or more.
lf the light doesn't come on and go off as specified,
replace the Ay'C thermostat.
There should be continuity between the A and C term!nals when power and ground are connected to the Band D terminals.
There should be no continuity when power is discon-nected.

8ge, replace the clutch set.
Check the pulley bearing play and drag by rotating
the pulley by hand. Replace the clutch set with a new
one if it is noisv or has excessive play/drag
Measure the clearance betlveen the pulley and the
pressure plate all the way around. lf the clearance is
not within specified limits, the pressure plate must be
removed and shims added or removed as required.
