222E.
10.21 Prime screw (26) with Loctite T primer and allow to dry.
10.22 Install screw (26) and washer (25) in clamp stud (20) using Loctite 241. Tighten screw (26) down
hard to bed in parts, then slacken and torque-tighten to 0.56 Nm (5 lbf in.).
10.23 Install actuator shim (27) and pan drag lever (29) on drag actuator (12).

10.27 Turn the pan drag knob boss (5) clockwise until any slack is taken up and drag begins to be felt
Install pan drag knob (3) on pan drag shaft (6), with `1' aligned with the index mark on mechanism
housing.
10.28 Apply maximum drag and ensure pin (4) does not foul face of casting (9). If necessary, dismantle
pan drag shaft (6) and pan drag push road (8) and install washers (7) as required.

Tilt mechanism
11
Assemble the tilt mechanism as follows (
Fig 6.4
):
11.1
Lightly lubricate components as follows:
11.1.1
All moving surfaces, particularly `O' rings and seals (5, 8 and 32), drag actuator (3) and
bearing (7) using white bearing grease. This grease must not be allowed to come into contact
with the drag surfaces.
11.1.2
Contact surfaces of drag shoe (35) and bearing housing (33), except for the area
around clamping screws (36), with grease GP50. This grease must not be allowed to come into
contact with the drag surfaces.
11.2
The correct orientation of the Omniseal (8), as shown in
Fig 6.4
is important. Renew the seal.
11.3
Fit new `O' rings and seals throughout.
11.4
Install Omniseal (8) in the tilt drag cover/brake disc assembly (31), observing correct orientation.
