6.3.2: REASSEMBLING THE REAR SUSPENSION
(For pictorial views of the assembly, refer to Fig. 2 on page 10)
Tools Required: Medium Flat Bladed Screwdriver
10mm A/F Spanner
Torque Wrench with 10 A/F socket
The re-assembly of the rear suspension is basically the reverse of the dis-assembly proce-
dure. Starting with the shorter rear Quad Link (5) ensure the rear Quad-Link (5) is com-
plete and correctly assembled (See Fig.3). Next make sure the rear Quad-Link (5) is cor-
rectly orientated (see fig. 5) and pass a 90mm M8 Shaft (9) through the rear Quad-Link
(5) and Main Frame (6). Next take the rear shock (7) and assemble the front mount of the
rear shock (7) using SKF LG/AF or Castrol Optimol T anti fret paste on the contacting sur-
faces, into the forward shock mount of the Mainframe (6). IMPORTANT. Ensure the rear
shock is the correct way up, with the blue Pro Pedal lever facing upwards. Assemble the
longer front Quad-Link (4) onto the Mainframe (6), and pass a 90mm M8 Shaft (9) through
the front Quad-Link (4), the Mainframe (6) and through the front of the shock (7) until the
M8 Shaft (9) is showing out the other side of the front Quad-Link(4). You should now have
both front and rear Quad-Links assembled onto the Mainframe (6), with the rear shock (7)
in position. Next lower the Swinging Arm (3) onto the rear suspension assembly and posi-
tion the Swinging Arm (3) onto the front Quad-Link (4) first. Pass a 90mm M8 Shaft (9)
through the front Quad-Link and Swinging Arm (3) until it has passed though the other
side. Next rotate the Swinging Arm (3) down to attach it to the rear Quad-Link (5) and the
rear of the shock (7). Once you have the Swinging Arm (3) in the correct position, make
sure that the rear Quad-Link (5), the Swinging Arm (3) and the rear shock (7) though
holes are all concentric with each other, and push through the 100mm M8 Shaft (8). Next
re-fit the M8 AeroSpace Nuts (3). IMPORTANT: before final tightening of the M8 AeroSpace
Nuts (3), it is important to make sure that there is a balanced amounts of thread showing
through the M8 AeroSpace Nuts (2) on each side of the front and rear Quad-Link assem-
blies. Using the screwdriver in the end of the M8 Shafts (8 & 9), and the 10mm spanner,
adjust all 4 M8 Shafts (8) accordingly. Refer to Fig. 6. Tighten all M8 AeroSpace Nuts (2) to
the recommended settings. (Refer
to the Tightening torque settings
in Section 8.0) Next make sure
that there is still a substantial
amount of Molykote 111 Silicon
covering all the KP5AX flanged
bearings. Refit the Bearing Caps
(1) by screwing them into the
links. Take care not to cross
thread the Bearing Caps (1). Us-
ing the screwdriver, tighten the
Bearing Caps (1) to stop them
from shaking loose. (Refer to the
Tightening torque settings in Sec-
tion 8.0). Finally, refit the rear
wheel into the swinging arm.
