Changing oil

HS 415 SM Model

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.

6. When level is correct, refit and tighten all filler/
level plugs.

Approximate capacities:

HS 415 SM - 6 pints (3.5 liters) per hub.
HS 515 SP - 8 pints (4.5 liters) per hub.
HP 519 SP - 8 pints (4.5 liters) per hub.
HS 716 SQ - 8 pints (4.5 liters) per hub.
HD 719 SQ - 8 pints (4.5 liters) per hub.

Recommended oil MIL-L-2105D.

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.

Service Instructions For HS415SM Model

Description

The hub gears are driven by a floating sun pinion
which is splined to a drive shaft. The gear meets with
three planet gears mounted in a carrier which is
bolted to the hub. The ring gear is two pieces splined
to the axle spindle, it also serves to support the outer
hub bearing cone. The hub is fully floating, running
on a taper roller bearing which is secured and ad­justed by a nut locking ring.

The unit is mounted on a removable spindle, bolted to
the axle housing.

Routine Maintenance

Service the vehicle every six months, checking the
following:

1. General condition of nuts, bolts and housing

2. Joints and seals for signs of leakage.

Tooling/Sealant List

Spring balance to read to 25 lbs. (12kg).
Hub nut spanner - E537.
Assembly tooling - E539.
Hub oil seal fitting tool - E540.
Loctite No. 277 locking compound.
Loctite No. 515 liquid gasket.
Loctite No. 609 sealing compound.

b. If this condition exists, do not handle.

c. Confirm material composition. Any flouro-

elestomer (Viton, Flourel or Tecomoflon) should
be considered dangerous but natural rubber and
nitrile are nonhazardous.

d. If flouroelastomer seals have been used, the

affected area must be decontaminated before
continuing.

e. Disposable heavy duty gloves must be worn and

the affected area decontaminated by washing
thoroughly with limewater (calcium hydroxide
solution).

f. Discard any clothing contaminated after use.

Note: Burning of discarded items is NOT RECOM­MENDED, except in an approved incineration process
where gaseous products are treated by alkaline
scrubbing.

Caution: Viton O-rings and seals (flouro-elas-

!

tomers) - safety hazards.
Viton material used in oil seals and O-rings
produces a highly corrosive acid (hydroflouric)

when subjected to temperatures above 315° C.

This acid is very toxic and should not be come in
contact with. We recommend the following
procedure when it is necessary to inspect any
equipment that has been subjected to high
temperature or fire.

a. Visually inspect any gaskets or seals that have

suffered from heat; they will appear black and
sticky.

Disassemble Planet Carrier Unit

• Unscrew and remove carrier capscrews and
washers.

• Using chain hoist, carefully remove planet carrier
assembly from axle. Place on bench or press and
support in an upright position with outboard end
of carrier facing down. Remove planet pin by
first removing set screw and then press pin down
(outboard) and out of carrier.

• Carefully remove planet gear.

• Repeat operations for other planet gear assem­blies.

• Remove and discard O-rings from planet pins.

• If thrust button needs changing, pull out of its
position in planet carrier inner face.

• Remove sealing compound from planet carrier
and hub mating faces using Loctite Chisel Gasket
Remover or by carefully scraping sealant from
faces.

Disassembling Planetary Ring Gear Unit

• Pull out axle shaft complete with sun gear, snap
ring and washer from axle spindle.

• Remove snap ring from groove in axle shaft then
pull off sun gear and thrust washer.

• Remove lockrings and hub retaining nut from
axle spindle.

• Insert extraction bolts into holes provided in ring
gear and tighten evenly to pull ring gear assem­bly, complete with outer hub bearing cone from

Removing Hub Unit

• Using suitable support, carefully remove hub
assembly from axle spindle and place on work
bench, outer end down.

• Carefully remove oil seal outer half from hub then
lift inner hub bearing cone.

• Inspect oil seal part for wear and damage.

• Check hub bearing cups for wear and damage. If
necessary, remove cups from hub using soft
metal drift pin.

Note: If either bearing cup or cone needs replacing,
a new cup and cone must be fitted.

• Inspect oil seal half parts and housing for wear
and damage.

Note: If any seal assembly parts need to be replaced,
a complete new assembly must be fitted.

• Inspect condition of hub spacer, removing for
replacement if required.

Hub/Axle Stub subassembly

248°F max.), then push into position on axle

stub.

• When oil seal housing has cooled, push bearing
spacer into position on axle stub.

• Fill bearing cone with grease using a bearing
packer or manually kneading grease between
rollers, race and cage, then push into position on
axle stub.

• Fit inner and outer hub bearing cups into position
on hub.

Assembly

HS 415 SM Model

• Remove hub oil seal assembly from package, fit
one half into hub and other into inner seal
housing as follows:

a. Do not remove seals from package until

immediately before installation. This protects
the super-finished seal faces from damage

and contamination.
b. Hub and oil seal housing must be clean.
c. Install face seal by means of special fitting

tool number E541. Pressure is applied

directly via the elastromeric part. For ease of

assembly moisten the bore and O-rings with

a water/spirit mixture (NOT OIL).
d. Press seal ring into hub/ seal housing using

even pressure on opposite sides of tool.

Ensure that the housing/hub surface 'A' lies

parallel to the seal face 'B'. The O-rings must

not be pinched in the hub/housing or partially

out of the bore.

• Assemble ring gear and ring gear carrier together
and secure with ring gear retainer.

• Press hub outer bearing cone onto ring gear
carrier journal.

• Clean metal surfaces with a lint free cloth, apply a
thin film of clean oil to metal faces.

Note: Keep oil off of other surfaces.

• Support hub with chain hoist, and carefully push
into position on axle spindle.

• Assemble guide tube from assembly tooling E
539 onto axle spindle, carefully pushing into
position on axle spindle. Use bumper or soft
metal hammer from assembly tooling to ensure
ring gear is driven on completely.

• Fit hub bearing nut and tighten hand tight.

• Remove chain hoist.

Hub Bearing Setting

HS 415 SM Model

• Torque hub nut to 190-210 lbs. ft. (258-285
N•m).

Note: The hub should be fully rotated several times
in both directions to ensure the hub bearings are
correctly seated.

• Secure a cord to a wheel stud and wrap cord
around hub, fasten free end to a spring balance.

• Apply a steady pull to spring balance and note
reading, ignoring the large force initially required
to start rotation.

• The correct spring balance reading should be
between 6 to 10 lbs. (2.7 to 4.5 kg) correspond­ing to a hub rolling torque of 3-5 lbs. ft. (4-7
N•m).

• If spring balance reading is outside limits stated,
adjust hub nut and check again, continuing until
correct figure is obtained.

• When hub setting is correct, fit lockrings, then
retaining ring.

Note: To align slots in nut with corresponding slots
in axle spindle, do not back off. Continue to tighten
nut until slots are aligned.
