Section 5 – Procedures
5.9-6 Brake Inspection
1. Remove the oil level plug from one of the
braking axle arms, as shown below.
2. Insert a 4.5 mm (front steer axle) or 5.2 mm (rear
rigid axle) feeler gauge into the drain port.
3. Use the gauge to check the gap between the
disks (A). The minimum distance allowed is
4.5 mm (front) or 5.2 (rear). Reinstall the oil level
plug.
4. Repeat the inspection on the other axle arm. If
the gap is smaller than 4.5 mm (front) or
5.2 mm (rear) between the disks of either arm
(i.e. the gauge doesn't fit), the brake disks must
be replaced on both arms.
5. Repeat the procedure on the opposite axle.

5.9-7 Oscillating Cylinder Bolt
Replacement
If upon inspection it is determined that the oscillating
cylinder bolts have missing or damaged torque seal,
the affected bolts must be replaced. If replacing
more than one bolt, do so one at a time to prevent the
cylinder from shifting.
1. Remove the affected bolt.
2. Clean the cylinder's corresponding internal
threaded hole thoroughly.
3. Replace the removed bolt with a new 1/2"-13 x
1-3/4" grade 8 bolt, applying liquid blue Loctite
242 or 243 to the bottom half of the bolts.
4. Hand tighten the bolt.
5. Torque the new bolt to 108 Nm (80 ft-lb).
6. Apply a line of torque seal to each new bolt
extending from the bolt head over the washer
and to the chassis wall.
