Rear End Coverplate / Rotor
0.05mm / 0.08mm
Rotor / Cylinder
0.08mm / 0.10mm
Starting at the rear end
5.1
If spacing rings (5) have been replaced, grind replacements to the exact width of the originals and locate
against the rotor side face, refit the PTFE ring (14).
5.2
Press ball bearing (7) onto the shaft.
5.3
Fit any shims (13) into the coverplate (3) and press coverplate onto the rotor/shaft. Set clearance.
5.4
Replace the o-ring (10) in cylinder groove.
5.5
Turn cylinder (1) upside down for ease of assembly.
5.6
Place rear coverplate assembly onto cylinder (1) via location dowels and bolt with 4 screws (12) and with
