NLGI Consistency #2.
If your axle is equipped with the E-Z Lube feature,
the bearings can be periodically lubricated without
removing the hubs from the axle. This feature con-
sists of axle spindles that have been specially
drilled and fitted with a grease zerk in their ends.
When grease is pumped into the zerk, it is chan-
neled to the inner bearing and then flows back to
the outer bearing and eventually back out of the
grease cap hold (see Figure 5-5). The procedure is
as follows:
1. Remove the rubber plug from the end of the
grease cap.
2. With a standard grease gun filled with a quality
wheel bearing grease, place the gun onto the
grease zerk located in the end of the spindle.
Make sure the grease gun nozzle is fully
engaged on the fitting.
3. Pump grease into the zerk. The old, displaced
grease will begin to flow back out the cap around
the grease gun nozzle.
4. When the new, clean grease is observed, remove
the grease gun, wipe off any excess, and
replace the rubber plug in the cap.
5.12 TROUBLESHOOTING INTRODUCTION
The following Troubleshooting Chart is based upon
the data obtained both from testing at the factory
and from applied situations in the field. It contains
symptoms and usual causes for the described prob-
lems, however DO NOT assume that these are the
only problems that may occur. All available data
concerning the trouble should be systematically
analyzed before undertaking any repairs or compo-
nent replacement procedures.
A detailed visual inspection is worth performing for
almost all problems. Doing so may prevent unnec-
essary additional damage to the compressor.
5.13 TROUBLESHOOTING GUIDE
SYMPTOM PROBABLE CAUSE REMEDY
ENGINE DOES NOT CRANK OR CRANKS ONLY WITHOUT STARTING:
NO FLASH CODE: Low Voltage or Battery Disconnected Check battery cables and tighten if neces-
sary.
Check ground wire for proper attachment to
frame. Tighten as required.
Recharge or replace battery if required.
Blown Fuse in Wiring Harness Remove and inspect fuse. Replace if neces-
sary.
Instrument Panel Connectors Loose or
Disconnected
Checked instrument panel connectors and
reattach if required.
Check instrument panel wires for broken con-
nections or corrosion. Clean and/or replace
if required.
Faulty SSAM Module Replace the SSAM Module.
COMPRESSOR SHUTS DOWN:
NO FLASH CODE: Blown Fuse in Wiring Harness Remove/Inspect fuse and replace if neces-
sary.
Instrument Panel Connectors Loose or
Disconnected.
Check instrument panel connectors and
reattach if required.
Check instrument panel wires for broken con-
nections or corrosion. Clean and/or replace
if required.
Faulty SSAM Module Replace the SSAM Module.
