Changing oil
Note: New and reconditioned axles are greased
where necessary, but are not filled with oil when then
leave the manufacturing facility.
Drain and refill oil on new units after the first month
or 100 hours while axle is still warm, then at intervals
of 1,000 hours or 6 months.
Oil Level
Check oil levels monthly or every 100 hours following
the procedure below.
1. Vehicle must be on level ground.
2. Remove differential oil filter plug and check oil
level. Add oil if necessary.
Warning: Never work under a vehicle supported
by only a jack. Always support vehicle with
stands. Block the wheels and make sure the
vehicle will not roll before releasing the brakes.
Note: Spicer recommends cleaning the magnetic
filler plug, drain plugs, and cleaning the breather.
Note: There is no oil sealing between the drive head
and hubs. Drive head and Hub oil levels should be on
the axle center line. When refilling add amounts
shown below to hubs then drive head and let sit in
axle for 15 minutes before checking levels at all
points. Add oil as necessary until level after settling
period.
Always check final oil level at drive head.
3. Raise the wheels off the ground and support with
proper stands.
4. Rotate each hub so the bottom of the hub filler/
level plugs are on the axle center line (level with
the differential filler plug).
5. Unscrew the plugs and check that oil level is at
the bottom of plug holes. If not, add oil to each
hub through plug holes then check level in drive
head.
6. When level is correct, refit and tighten all filler/
level plugs.
