CLEANING AND INSPECTION
After disassembly is complete:
1. Wash all metal parts, with the exception of the pressure
plate and lining, in a cleaning solvent and dry them.
2. Inspect parts not included in the maintenance kit for
nicks, burrs, corrosion and/or excessive wear.
3. Replace any part not considered reusable, after
inspection, with genuine Bendix replacement parts only.
REASSEMBLY
ASSEMBLY OF PULLEY-BEARING SUB-ASSEMBLY
1. (Spaced bearing assembly) (Fig. 11) Install snap ring (5)
using WaIdes Truarc snap ring plier 6500 or equivalent.
2. Support the pulley on the front or tapered end. Press in
bearing (4), seal side up, until bearing bottoms on snap
ring (5). Pressing fixture should contact outer race.
3. Install tapered snap ring (2), flat side towards bearing,
using Waldes tool #6500.
4. Invert pulley, tapered end up. Position spacer (1)
concentric with inner race of previously installed bearing.
Pack grease (Chevron SRI #2) around spacer. Press
in second bearing (3), seal side up, until inner race
contacts spacer. Pressing fixture must contact both inner
and outer races.
5. (Matched Bearings) To install the closely spaced
bearings as shown in Fig. 12, matched bearings 291458
must be used. Support the pulley on the front or tapered
end and press in the first bearing, seal side down, until
bearing bottoms on shoulder in pulley. Press on outer
race of bearing. Press in second bearing, seal side up,
bottoming on first bearing.
6. Install tapered snap ring.
ASSEMBLY OF PULLEY ASSEMBLY ON BRACKET
SHAFT
1. Support bracket with shaft pointing up. Apply one band
of Loctite RC 601 around shaft for each bearing as
shown in Fig. 9. Apply one band of Loctite RC 601 on
each race.
NOTE: When using Loctite, parts must be clean and free
of oil and grease. Allow 24 hours for complete curing.
2. Slide pulley assembly on shaft, making sure the bottom
bearing inner race bottoms against bracket.
3. Position o-ring (9) as shown in Fig. 9. Install piston cup
(8), lockwasher (6) with single tang located in groove in
shaft, and bearing nut (7). A tool similar to that shown in
Fig. 10 may be fabricated to tighten the bearing nut to
100-150 ft. lbs. One tang on the lockwasher must then
be bent up into the appropriate slot in the nut. Care must
be taken not to injure the finish on the I.D. of the piston
cup.
FINAL ASSEMBLY (Ref. Fig. 9)
1. Support bracket-shaft pulley assembly with shaft pointing
up. Lubricate inner surface of piston housing and lower
half of shaft with lubricant BW 655M.
2. Lubricate the large o-ring (12) and install on piston. Install
the Teflon back-up ring (15) (if used) in the internal groove
in the piston (13), then lubricate and install the smaller
