<strong>Installation</strong><br />
Axle Preparation<br />
The following describes the procedure for preparing a trailer<br />
axle for system installation.<br />
The Spicer Tire Maintenance System is designed to be<br />
used on trailer axles with hollow tapered (D22 series) or hollow<br />
parallel (P22 series) spindles with inside diameter<br />
machined to a minimum depth of 1.0". Some trailer axles have<br />
a solid web inside the spindle under the inner bearing that<br />
may be modified to allow for a hose to be routed through the<br />
obstruction. Consult with the axle manufacturer for approval<br />
to modify the axle before installation of the <strong>Dana</strong> Spicer Tire<br />
Maintenance System.<br />
The Spicer Tire Maintenance System does not require<br />
the removal of the wheel assemblies. However, the tires must<br />
be blocked and the trailer supported to prevent movement<br />
during installation.<br />
WARNING: Block all wheels before beginning this<br />
installation procedure. Never work under a vehicle supported<br />
by a jack.<br />
1. Block tires to keep the trailer from moving.<br />
D22-Style<br />
Tapered Spindle<br />
OR<br />
218UX008<br />
P22-Style<br />
Parallel Spindle<br />
218UX007<br />
CAUTION: Do not weld on axles with hoses installed as<br />
hoses may be damaged.<br />
Note: The Maintenance System cannot be installed on solid<br />
spindle trailer axles.<br />
Note: The Maintenance System is not compatible with Axilok<br />
or cotter pin locked spindle nuts. Use of the 3-piece jam<br />
nut system with the maintenance system is recommended.<br />
Pro-Torque nuts may require use of an optional<br />
hubcap spacer.<br />
2. If the trailer is equipped with an air suspension system,<br />
deflate the air springs or support the trailer<br />
frame to prevent settling during installation.<br />
3. If the wheel end is oil lubricated, drain the oil from<br />
the hubcap and discard.<br />
4. Remove the hubcap bolts and hubcap.<br />
5. Remove the spindle plug from the end of the spindle.<br />
6. Inspect spindle plug bore and remove any burrs or<br />
sealant.<br />
7. Check the inside of the spindle to insure that there is<br />
a passage through the axle to allow installation of the<br />
air line.<br />
8. Locate the three 1/4" pipe plugs on the top of the<br />
axle tube near the center and remove. If the axle was<br />
not prepared at the factory with the three 1/4" pipe<br />
thread holes, proceed to step 10.<br />
9. Proceed to the Component <strong>Installation</strong> section.<br />
