ASSEMBLY
1. Install twist beam front pivot bush using special
tools.
2. Lift and properly position the twist beam.
3.
Gen-3 Installation Procedure:
a) It requires specific care for bolt tightening
sequence and torque value.
b) Sequences of bolt tightening of inner flange
into the knuckle / RTB normally carried out as
described in view H 2-3 Kg-m.
c) Tightening torque value (pre tension) is applied
to bolts in sequence of 1-3-2-4.
d) Final tightening torque value must be then
applied with same sequence.
e) Bolt tightening sequence must be followed to
avoid abnormal residual face deformation of
gen-3 bearing.
f) Apply adhesive thread locker on bearing
mounting screw before tighten to RTB
4. Tighten the cross bolt of the twist beam.
5. Fix the brake lines and parking brake cable
mounting on the torsion beam.
6. Fix the back plate assembly along with brake
shoes and stub axle to the torsion beam.
7. Fit the brake drum.
8. Fix the shock absorber and coil spring to the
torsion beam. (Refer the re-fitment of shock
absorber and coil springs).
9.
Top up the brake fluid and carry out the
bleeding of brakes. (Refer brakes).
NOTE
1. Springs having same color code should be
assembled on LH & RH with correct orientation.
2. Axle system to be installed and fasteners for
Pivot Bush and Damper Bottom Bush to be
tightened.
3. All fasteners to be paint marked after torque
tightening is done.
4. Jack should not be placed below RTB.
5. After assembly, check bearing for smooth
running. hub should not drag while rotating.
6. Torque tightening speed for the fasteners must
be 10 to 15 rpm while using Electrical torqueing.
7. No nonmetal / metal burr, debris, impurity
allowed on fastener, fastener bearing surface or
surface where fastener will sit while assembly.
8. Unless
otherwise
specified,
no
oil/lubricant/thread locker allowed on fastener,
fastener bearing surface or surface where
fastener will sit while assembly.
9. All self-locking type fasteners are not to be re-
used once joint is dismantled.
10.Suspension system (RTB, Dampers, ARB
Clamp, spring mounting points on BIW, to be
free from any coating.
