E210 and E220 VAR02: Once maximum travel is
attained (see tabel 1) it becomes necessary to readjust
value P by using the spacers incorporated in the
assembly
4.2 Spare Parts
Friction parts wear according to the amount of clutch
work which, after a particular running time, requires the
simul taneous replacement of the rotors (203) or (204)
and the moving armature assembly (331).
Caution: Excess grease causes bearings to
overheat.
Reassemble the equipment following the procedure in
reverse order.
E210 and E220 VAR02 :
Bearings are greased on assembly with ELF ROLEXA
2, but they should be greased at regular intervals,
depending on use. Tables 2 and 3 below give the
intervals and average quantities of grease and a
non exhaustive list of suitable greases for normal
applications.
3.3.2 Installing VAR05
• After adjusting the drive keyway, fit the assembled
inductor on the shaft, then the adjustment spacer,
followed by the assembled bearing casing, lastly
clamp the whole axially on the shaft.
Caution: The coupling flange (528) is not
factory fixed.
• After clamping the device axially on the shaft,
assemble the coupling flange (528) with the bolts
provided, tightened to torque (see Table 1) and
locked with a Loctite 243 type or equivalent product
NB : VAR05 is supplied with a pre-set airgap, however
after fitting, check the travel (measured in disengaged
position).
• Also check in disengaged position, that
the assembled moving armature (331) rotates
without contact
• Fit the coupling hub (507) onto the 2nd shaft
• Put the spider (730) inside the coupling flange (528)
• Assemble the moving part with the receiving part
by meshing the coupling hub teeth into the hollows
of the teeth of the spider (730)
It is essential during fitting to respect dimension
E (fitting the flexible coupling) (see tabel 1 and
Appendix).
4 Maintenance
4.1 Maintenance
E210 and E220 VAR00:
Bearings are greased on assembly with ELF ROLEXA 2.
After about 5000 h running it is necessary to check the
bearings and change all grease.
Changing the grease:
Remove the circlips (947), then the inductor with its
bearings. Remove the circlips (946), then the bearings
(803). Clean the bearings, then grease them again (see
table 3 for types of grease to use). Put a quantity of
grease equivalent to one third of the volume enclosed
between the outer race and inner race.
