Installing the new Differential Cover
IMPORTANT :
These covers have been designed for use with the most
commonly available versions of the axle assemblies listed on
the model range. Some modifications, such as grinding the
differential cover or re-routing the brake lines, may be required
for fitment to some applications.
F Clean all oil residue off the differential housing.
F Place the ARB Differential Cover in position on the differential
housing to ensure adequate clearance to surrounding
components.
NOTE : Checking for clearance between diff cover and all
internal parts is crucial before tightening the cover
bolts. Failure to do this may cause damage to your
differential.
NOTE : Due to inconsistent tapping depths on the factory
axle housings, it may be necessary to tap the
threads deeper, or slightly shorten some of the
bolts. Check that the supplied bolts will clamp down
on the diff cover properly.
F Apply gasket sealant, or a replacement gasket to the flange of
the differential housing.
F Install the ARB Differential Cover onto the housing and screw in
the bolts.
NOTE : Dana 60 differentials utilise 3/8” UNC Cap Screws
which must be torqued to 61.6Nm [45.4ft-lb]. Dana
30, 35 and 44 differentials utilise 5/16” UNC Cap
Screws which must be torqued to 34.5Nm [25.4ft-lb].
NOTE : Land Rover Salisbury models require the use of
metric M10 Cap Screws (not included). Use torque
settings to suite the grade of cap screw purchased.
F Tighten each bolt to the required torque.
F Install the drain plug and hand tighten using an 8mm Allen Key.
F Using the dipstick to check the oil level, fill the differential with the
appropriate oil to the required level, ensuring not to overfill.
F Install the filler plug/dipstick and hand tighten with an 8mm Allen
Key.
