Table 6, Dana Spicer Drive Axle Lubricant Capacities
NOTE: Some Dana Spicer axles have a
small tapped and plugged hole near and
below the housing oil fill hole. This smaller
hole is for a lubricant temperature indicator
only, and should not be used as a fill or level
hole.
6.1
Fill the axle through the oil fill hole or
standpipe opening. Lubricant should be
level with the bottom of the oil fill hole, or
the top of the standpipe opening. To
check fluid level, see
Fig. 2
.
6.2
Install and tighten the fill plug 40 to 60
lbf·ft (54 to 81 N·m).
Two-Speed Axles With Shift Unit
Dana Spicer and Meritor
1.
Remove the shift unit housing cover. See
Fig. 6
.
Drain and discard the old lubricant. Discard the
housing cover gasket.
2.
Thoroughly wash the axle shift parts and housing
cover, and allow them to air dry.
3.
Install the housing cover and a new cover gas-
ket. Tighten the housing cover capscrews 90 to
110 lbf·in (1020 to 1240 N·cm), then remove the
oil fill plug from the cover.
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. To
prevent component damage, do not mix engine
oil and automatic transmission fluid.
4.
Using the recommended lubricant, fill the shift
unit housing through the oil fill hole until the lubri-
cant is level with the bottom of the opening.
5.
Coat the threads of the fill plug with a small
amount of Loctite® 242, or equivalent sealant.
Install the fill plug finger-tight in the rear axle shift
unit housing. Using a wrench, tighten it an addi-
tional 1-1/2 turns.
