Warning
When working on air system components the following precautions
should be observed.
1. Stop engine when working under a vehicle. Always block the vehicle
wheels to prevent a fore or aft roll. Bleeding off system pressure may
cause the vehicle to roll. Keep hands away from brake chamber
push rods and brake adjusters; they may apply as system pressure
drops.
2. Never connect or disconnect a hose or line containing air pressure.
It may whip as air escapes. Never remove a component or a pipe
plug unless you are certain all system air pressure has been
exhausted.
3. Never exceed recommended working air pressure and always wear
safety glasses when working with air pressure. Never look directly
into component ports or direct a pressurized air flow at anyone.
4. Never attempt to disassemble a component until you have read and
understood all recommended procedures. Some components contain
powerful springs and injury can result if not properly disassembled.
Use only proper tools and observe all precautions pertaining to the
use of those tools.
Important Note
Place vehicle in neutral and disconnect batteries before working on
the electrical system.
Installation Tips
1. Test the batteries before installing the starter.
Batteries must be in good condition, have the proper capacity and
be fully charged. A defective or discharged will result in low
voltage which will stress the starter and may result in early failure.
This will also cause early failure of the Series Parallel Switch.
Batteries with insufficient capacity will result in poor starter
performance especially in colder temperatures.
2. Inspect all wire and battery cables.
and starter wiring must be of the proper size and free of corrosion.
High resistance in the starter circuit will result in slow or sluggish
starter performance due to low current flow. This may result in
starter failure. Many starters are needlessly replaced
for this reason.
3. Inspect for loose and corroded connections.
cable clamps and terminal ends must be clean and tight to minimize
circuit resistance.
4. Check starter amperage draw.
current draw will cause slow cranking and starter failure. This will
also cause excessive arcing and burning in the series parallel
switch and solenoid. This may be caused by a defective starter,
improper starter application or engine problems.
5. Inspect the flywheel ring gear.
ring gear will result in premature drive wear and in some conditions
poor drive engagement into the ring gear.
6. Use proper mounting hardware.
screws and lock-washers to mount the starter to the engine
housing.
7. Rotatable drive housing.
This starter may be equipped with a 24-position
rotatable drive housing. Read these instructions
before changing the position of this housing.
In order to match the solenoid position of the original starter it may
be necessary to rotate the drive housing of the starter. To change
the position of the drive end housing remove the six socket screws
from the housing mounting flange and rotate the housing to the
correct position. Make sure that the gasket that seals the drive
housing to the starter is still in proper position. When the housing is
properly positioned reattach the six socket screws and tighten to
13-17 ft. lbs. torque. Place the rubber plugs provided in the blank
bolt holes to properly seal the housing flange when the unit is
mounted to the engine.
