12.16 Before installing the tilt mechanism, degrease the pan brake contact surface on the pan drag top
plate (
Fig 6.5
, item 14)
12.17 Install bearing shim (9) on tilt mechanism (24).
12.18 Install tilt mechanism (24) in mechanism housing (16), ensuring spring actuator (30) engages
with needle bearing. Secure with two screws (25) and two screws (26), using Loctite 222E.
12.19 Working through the hole in the mechanism housing assembly (16), tighten the balance
mechanism screw (34) until it just nips the spring, then tighten a further two full turns to preload the
spring.
12.20 Using Loctite, install cap (35) in hole in the mechanism housing assembly (16).
12.21 Lubricate the thrust washer components (12) with white bearing grease and install in mechanism
housing (16), ensuring orientation is as noted during disassembly.
12.22 Lubricate the shaft of the balance knob assembly (13) with M204G grease screw into the
adjustment slide (17). Secure balance knob with Spirol ring (14).

Install the remaining tilt mechanism components as follows (
Fig 6.4
):
13.1 Install spring element (17) and friction element (18) in each brake shaft (19, 27). Install tilt brake
insert (28) in tilt brake shaft (27).
13.2 Screw both brake shafts into outrigger (9) as far as they will go and install a brake knob (20) on
each shaft so that, when fully applied the knob is vertical and, when turned fully counter-clockwise, the
brake is off. Secure each knob with a screw (21) and Loctite 222E. Secure cap (22) to each knob with
Silcoset.
13.3 Lubricate the thrust washer components (10) with white bearing grease and install in outrigger
(9), ensuring orientation is as noted during disassembly.
13.4 Lubricate the tilt drag knob boss (11) with M204G grease and install, complete with drag knob
retaining shaft (14), in the thrust bearing (10). Secure with tilt drag retainer/stop (26) and three screws
(25).
13.5 Turn the tilt drag boss (11) clockwise until any slack is taken up, then turn the outrigger in both
directions to confirm that movement is smooth and quiet. Degrease thread in drag knob retaining shaft
(14).
13.6 Install tilt drag knob (16) on drag knob retaining shaft (14), with `0' aligned with the index mark on
outrigger. Secure with screw (24), but do not tighten. The tilt drag knob is adjusted after assembly of the
head.
Platform
14
To install the platform, proceed as follows (
Fig 6.3
):
14.1 If removed, install dowel pin (42) in platform (41) to leave the end projecting 3.5 mm. Loctite 638
may be used to secure the dowel pin if required.
14.2 Degrease three threaded holes in the top face of tilt housing (24), two threaded holes in the edge
of platform (7), one screw (36). and four screws (8).
