Two-Speed-Axle Shift Unit
Lubricant Level Inspection
Dana Spicer and Meritor Axles
If equipped with a two-speed-axle shift unit, use the
following directions.
NOTICE
Failure to keep lubricant at the specified level
could cause damage to the axle shift unit.
1. Clean the shift unit oil fill plug, and the area sur-
rounding the plug. See
Fig. 7 . Turn the fill plug in
a counterclockwise motion and remove the plug.
2. Insert a finger or pipe cleaner into the fill plug
hole and check the fluid level. The lubricant level
should be maintained at the bottom of the fill
hole. If low, add the specified lubricant.
NOTICE
Before adding additional lubricant, make sure of
the type currently in the shift unit. To prevent
component damage, do not mix engine oil with
automatic transmission fluid.
IMPORTANT: When the ambient temperature is
above 0°F (–18°C), use SAE 10 heavy-duty en-
gine oil, API service classification SD (sulfated
ash content must not exceed 1.85%). When the
ambient temperature is below 0°F (–18°C), use
one part kerosene to three parts SAE 10 heavy-
duty engine oil, API service classification SD
(sulfated ash content must not exceed 1.85%).
This cold-weather mixture can be safely used
up to 32°F (0°C).
Commercially available automatic transmission
fluid may be used in place of SAE 10 engine oil.
Automatic transmission fluid can be used for all
temperatures; do not mix it with kerosene.
3. Apply a small amount of Loctite® 242, or equiva-
lent sealant, to the threads of the fill plug. Install
the fill plug finger-tight; then, using a wrench,
tighten it 1-1/2 turns past finger-tight.
