FRONT AXLE _____________________________________________________________
To check front axle fluid, determine which axle is used on
your mower. Early mowers have a rubber plug aligned
with the axle shafts center line. Later mowers have a hex
plug below the level of the axle shafts center line.
Early Style: Remove rubber plug (A-Early) from
differential cover. Fluid level should be between 1-1/8 in.
(2.8 cm) and 1-1/4 in. (3.2 cm) below fill hole. Add
Mobilfluid 424 or SAE 30 wt. as required to bring fluid to
correct level. Insert plug and clean up any spilled fluid.
Later Style: Remove hex plug and check fluid level.
Fluid should be up to the bottom of the plug. Add
Mobilfluid 424 or SAE 30 wt. as required to bring fluid to
correct level. Insert plug and clean up any spilled fluid.
To drain fluid:
1.
Place a suitable container under front axle.
2.
Remove bottom five screws (B), and loosen
remaining screws from differential cover.
3.
Being careful not to damage sealing surface, or
deform cover, break seal to drain fluid into pan.
4.
Remove differential cover and apply bead of RTV
sealant to axle housing, inside of cover holes.
5.
Assemble cover bolts. Torque bolts to 16 - 24 ft. lbs.
(21 - 32 Nm).
6.
Remove plug (A), and fill with 23 ounces (680 ml)
(Early Style) or 18 ounces (532 ml) (Later Style) of
Mobilfluid 424 or SAE 30 wt. oil to bring fluid to
correct level. Inert plug and clean up any spilled
fluid.
