5.10-6 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 01/2”-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-lbs).
6. Apply a line of torque seal to each new bolt
extending from the bolt head over the washer
and to the chassis wall.
5.10-7 Oscillating Cylinder Replacement
CAUTION
The oscillating axle cylinder weighs approximately
19.5 kg (43 lb), so a second person to assist with
the removal and replacement would be helpful.
1. Wedge a block of wood between the front
axle and the chassis, to prevent the axle from
oscillating during the procedure.
2. Remove and set aside the base cover from the
oscillating axle end of the chassis.
3. With a rag in hand to catch any leaking oil,
slowly loosen the bleeder screw to release any
trapped air within the cylinder, then tighten it
again. Slowly loosen the oscillating axle cylinder
hoses to release the pressure, then disconnect
them fully, being sure to plug the hose ends.
