35–05 Two-Speed-Axle Shift
Unit Oil Changing
1. Remove the shift unit housing cover (see Fig. 2),
and drain the old lubricant. Discard the housing
cover gasket, and the old lubricant.
2. Thoroughly wash the axle shift parts and housing
cover, and allow them to air dry.
3. Install the housing cover and a new housing
cover gasket. Tighten the housing cover cap-
screws 90 to 110 lbf·in (1020 to 1240 N·cm),
then remove the oil fill hole plug from the cover.
4. Fill the shift unit housing through the oil fill hole
until the specified lubricant is level with the bot-
tom of the opening.
IMPORTANT: When the vehicle operating tem-
peratures are above 0°F (–18°C), use SAE 10
heavy-duty engine oil, API service classification
SD (sulfated ash content must not exceed
1.85%). When the vehicle operating tempera-
tures are below 0°F (–18°C), use one part of
kerosene to three parts of SAE 10 heavy-duty
engine oil, API service classification SD (sul-
fated 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 kerosene with auto-
matic transmission fluid.
5. Apply a small amount of Loctite 242, or an
equivalent sealant, to the threads of the oil fill
hole plug. Install the oil fill hole plug finger-tight;
then, using a wrench, tighten the plug 1-1/2 turns
more.
