WORK INSTRUCTIONS – DANA KIT PART NUMBER: 326837

Kenworth Campaign Number: 01KW7
Kenworth Recall Bulletin Number: C-E-101

Below are work instructions for the replacement of specific tie rod end crosslink and brake assemblies from vehicles equipped with Dana E-1000I
or E-1200I steer axles and Dana ES165-5L ES brakes.

Tie Rod Assembly Replacement

1. Disconnect the tie rod end.

2. If the cross tube is being replaced, count the number of
exposed threads on the tie rod end.

3. Loosen the clamp nut and unscrew the tie rod end.

4. Install new tie rod ends or new cross tube.

NOTE: Cross tube has right-hand and left-hand threads for
corresponding sides of the vehicle.

5. Thread tie rod end into cross tube past the tube split. The
number of threads exposed from the tube should be equal
on both left and right tie rod ends.

CORRECT

The threaded portions of both
tie rod ends must be completely
inserted in cross tube split

Equal threads exposed on
left and right tie rod ends

INCORRECT

Threaded end is not completely
inserted in cross tube split

7. Install tie rod end into knuckle tie rod arm. Secure with
slotted nut and tighten to 120-160 ft. lbs. (163-217 N€m).

General Information

DANGER: Avoid creating dust possible cancer and lung

!

disease hazard

While Dana does not offer asbestos brake linings, the long-term
effects of some non-asbestos fibers have not been determined.
Current OSHA Regulations cover exposure levels to some
components of non-asbestos linings but not all. The following
precautions must be used when handling these materials.

1. AVOID CREATING DUST. Compressed air or dry brushing
must never be used for cleaning brake assemblies or the
work area.

2. DANA RECOMMENDS THAT WORKERS DOING BRAKE
WORK MUST TAKE STEPS TO MINIMIZE EXPOSURE TO
AIRBORNE BRAKE LINING PARTICLES. Proper procedures
to reduce exposure include working in a well ventilated
area, segregation of areas where brake work is done, use
of local filtered ventilation systems or use of enclosed cells
with filtered vacuums. Respirators approved by the Mine
Safety and Health Administration (MSHA) or National
Institute for Occupational Safety and Health (NIOSH)
should be worn at all times during brake servicing.

3. Workers must wash before eating, drinking or smoking;
shower after working, and should not wear work clothes
home. Work clothes should be vacuumed and laundered
separately without shaking.

4. OSHA Regulations regarding testing, disposal of waste and
methods of reducing exposure for asbestos are set forth in
29 Code of Federal Regulations §1910.001. These
Regulations provide valuable information which can be
utilized to reduce exposure to airborne particles.

5. Material safety data sheets on this product, as required by
OSHA, are available from Dana.

Brake Maintenance Preliminary Steps

Prior to performing any maintenance requiring removal of the tire
and wheel, the following preliminary steps must be taken to ensure
your safety. Refer to Figure 3.

Support On
Jack Stands
of Adequate
Capacity

Block Wheels

Figure 3

1. Set parking brake and block wheels to prevent vehicle
movement.

2. Raise drive axle with a jack and support on suitable stands.

WARNING: Never work under a vehicle supported by a

!

jack.

3. Cage spring-type brake chamber following vehicle
manufacturer’s instructions.

Removal/Disassembly

Drum Removal

1. Perform “Brake Maintenance Preliminary Steps”.

2. While depressing locking sleeve, back off brake adjuster
adjustment nut on manual brake adjusters. Refer to
Figure 4. Continue turning until shoes are fully returned to
released position and clear of drum. On self adjusting
brake adjusters, follow manufacturer’s instructions.

NOTE: With outboard mounted drums go to step 6.

Turn Adjuster Nut to

Back-Off Adjustment

Figure 4

3. On drive axles, remove stud nuts and axle shafts. If used,
remove Iockwashers and taper dowels. If necessary,
loosen dowels by holding a brass drift in the center of the
shaft head and striking it a sharp blow with a hammer. On
trailer and steer axles, remove hub cap.

WARNING: Do not strike the axle shaft flange with a

!

hammer. Do not use chisels or wedges to loosen shaft or
dowels.

4. Remove axle spindle nut(s) and washer.

5. While rocking drum, pull outboard enough to allow
removal of outer wheel bearing.

6. Remove drum by pulling outboard while rocking from side
to side. If shoes are not clear of drum, return to Step 2
above.

CAUTION: If difficulty is found on removal, do not force

!

drum. Excessive pulling force may damage brake
components.

Brake Adjustment - Manual Brake Adjuster

NOTE: An assistant is required to make a brake adjustment.

WARNING: Block all wheels before beginning this

!

adjustment procedure

To determine whether Dana Brakes require adjustment, applied
stroke is measured and compared to the maximum value for the air
chamber size in use on the vehicle.

1. Perform “Brake Maintenance Preliminary Steps”

described earlier.

2. With air chamber pushrod fully retracted, measure
distance from face of air chamber to centerline of clevis pin
hole. Refer to Figure 15. If the measurement is not within
ranges shown in Table 1, reposition clevis. Remeasure the
distance and repeat until within range. Record exact
measured distance as dimension “A”.

3. Apply and hold an 80 psi brake application, and again
measure from face of air chamber to clevis pin centerline.
Refer to Figure 16. Record distance as dimension “B”.

4. Subtract dimension “A” from “B”. The difference is applied
stroke. Compare applied stroke to maximum value in
Table 2. If applied stroke equals or exceeds maximum
applied stroke shown, adjust brakes. If less than the
maximum, no adjustment is required and you may perform
Brake Operation Check.

Table 2

NOTE: If adjustment is necessary, Dana Brakes are adjusted to

achieve proper free stroke. The difference between free stroke and
applied stroke is merely the method used to move the brake adjuster
from rest. Applied stroke uses an 80 psi brake application; free
stroke is measured using a lever to move the brake adjuster until the
brake shoes contact the drum. If applied stroke exceeded the
maximum and adjustment is necessary, adjust the brakes as
described in steps 5 through 8 below.

06SE01TBC6298

5. Take “A” dimension exactly as before. Take “B”
measurement using a lever to move brake adjuster as
shown until the shoes contact drum. Refer to Figure 17.
The result of “B” - “A” is brake free stroke. Adjust free
stroke to within range specified in Table 2.

6. To adjust free stroke, depress locking sleeve on brake
adjuster adjustment nut and turn in direction required.
Recheck free stroke to verify it is within range. Make sure
sleeve is “locked” when adjustment is completed.

7. Verify that brakes are not dragging by spinning wheels by
hand or tapping drum lightly with a hammer and listening
for a sharp ringing sound.

8. Perform Brake Operation Check, to verify proper
operation of brakes before releasing vehicle for service.

Dimension B

Brake Adjustment - Self Adjusting Brake
Adjuster

1. Brake adjustment for self adjusting brake adjusters is the
same as for manual brake adjusters.

2. Refer to the Self Adjusting Brake Adjuster Manufacturer’s
Instructions for proper installation.

Brake Operation Check

NOTE: An assistant is required to make a thorough brake operation
check.

1. Apply brakes to 80 psi and hold. Check all air line fittings
and air chambers for leakage.

2. Apply and release brakes while observing operation of
brake adjusters on each axle. As brakes are applied and
released, brake adjusters should move in unison visually.

3. Investigate source and make corrections for any
discrepancies found in Steps 1 and 2.

4. Drive vehicle at low speeds in a safe area and make several
brake applications to verify safe operation and absence of
pulling, grabbing, or noise. If any of these are noted,
investigate and repair prior to releasing vehicle for service.

CAUTION: Never release a vehicle for service if any brake

!

discrepancy - no matter how minor - is evident.
