Servicing the Planet Carrier Assembly
Section C
To gain access to the planet carrier refer to Sections D and E and remove the axle arm,
sun gear and brake plates.
Withdraw the brake spacer plate from within the axle arm and lift out the planet carrier
assembly.
Check the teeth on the planet gears, sun gears and annulus gears for wear. The planet
gears should run freely on the planet pins without excessive radial play.
To dismantle the planet carrier knock the spring dowels into the planet pins and lightly
drift the planet pins out of the carrier. Remove the thrust washers, planet gears and
needle bearing. The axle shaft thrust washer is retained by a circlip which can be
removed to allow inspection of the washer. Inspect all the individual components for
wear and replace as necessary. Before re-assembling the planet carrier remove the old
spring dowel pins from the planet pins and ensure new spring dowel pins are fitted on
assembly.
If necessary the annulus, which is retained by the dowels, can be withdrawn from the
axle arm. If the annulus is replaced the dowels should also be replaced. Ensure the
annulus is fitted squarely into the axle on re-assembly.
Locate the planet carrier assembly back into the axle arm engaging the teeth on the
annulus gear. Refit the brake spacer plates.
Refit the brake disc plates and sun gear as described in Section E.
Refit the axle arm as decribed in Section D.
Refit the drain plug, remove the combined filler/level plug and top up the axle oil.
