side plate. Ensure that the slot in the adjustment slide is towards the RH side plate and that circlip (18)
is positioned on the end face of the boss of the RH side plate.
16.5 Using hand pressure, push the RH side plate fully home in its bearing in mechanism housing
(16). Using circlip pliers, install circlip (18) on the boss of the RH side plate.
16.6 Lubricate adjustment slide sleeve (21) with Easyrun 50 grease and locate it over adjustment
slide (38) in the head. Rotate the adjustment slide sleeve to align holes for screws and Spirol pin with
holes in mechanism housing, noting that there is only one position in which all the holes are aligned.
Secure the adjustment slide sleeve in position with three screws (27) but do not tighten the screws at
this stage.
16.7 Install the Spirol pin (22) in the adjustment slide sleeve. Drive in the pin until the end is below the
face of the adjustment slide sleeve.
16.8 Fully tighten three screws (27).
Tilt unit assembly
17 Assemble the tilt unit as follows (Fig 6.4):
17.1 Degrease eight threaded holes in the boss of constant drag assembly (8) and two screws (13).
17.2 Assemble thrust washer (3) onto drag actuator shaft (2).
17.3 Lubricate needle roller bearing (4) with white bearing grease and assemble a thrust washer, the
needle roller bearing and a second thrust washer on the tilt drag actuator shaft (2).
17.4 Assemble friction plate assembly (5) onto drag actuator shaft (2).
17.5 Position the tilt drag actuator shaft, complete with thrust bearing components and friction plate
assembly, in recess in tilt drag housing (1).
17.6 Turn the friction plate assembly to align holes for screws and Spirol pins, noting that there is only
one position in which all the holes are aligned.
17.7 Apply Loctite 222E to threads of six screws (30) and secure friction plate assembly (5) to tilt drag
housing (1). Do not tighten screws at this stage.
17.8 Install two Spirol pins (6) through friction plate (5) into tilt drag housing (1). Drive them in until the
ends are below the surface of the friction plate. Tighten six screws (30).
WARNING!: The labyrinth assembly (3364-20) and the constant drag assembly (3364-21)
require special equipment for assembly and should not be dismantled. If faulty, each
assembly must be replaced with a new unit.
If the labyrinth assembly (7) constant drag assembly (8) or spacer (28) are replaced, it
will be necessary to adjust the thickness of the tilt shim pack. This requires the use of
shim setting tool, Part No, T61463.
NOTE: While tightening screws (30) to secure the friction plate assembly (5), rotate shaft (2) to
ensure thrust bearings and washers are not trapped.
