12.7 Fit equal numbers of shim washers (20) on each side of bearing (19) to minimise side play
between the adjustment slide (18) and actuator shaft (31).
12.8 Using tool 3431-912TL, secure dowel (21) in adjustment slide (18) using Loctite 601.
12.9 Assemble spring actuator (30), spring (32), end washer (34) and screw (35).
12.10 Install two shim washers (29) on spring actuator (30).
12.11 Position the assembled spring actuator in the mechanism housing (17), ensuring spring actuator
(30) engages with needle bearing in RH side plate (7).
12.12 Apply Loctite 221 to the thread in the actuator shaft (31) and push the assembled adjustment
slide (17) and actuator shaft into the mechanism housing (17) from the outside, so that the slot in the
adjustment slide (17) aligns with the hole in the mechanism housing.
12.13 Lubricate the thrust washer components (13) with white bearing grease and install in mechanism
housing (17), ensuring orientation is as noted during disassembly.
12.14 Lubricate the shaft of the balance knob assembly (14) with M204G grease and screw into the
adjustment slide (18). Secure balance knob with Spirol ring (15).
12.15 Screw in the balance knob until needle roller (16) can be pushed fully home.
12.16 . Apply Silcoset 153 around lower edges of mechanism housing cover (22) and install
mechanism housing cover (22) on mechanism housing (17). Secure with three screws (7).
12.17 Before installing the tilt mechanism, degrease the pan brake contact surface on the pan drag top
plate (Fig 6.4, item 19.)
12.18 Install bearing shim (9) on tilt mechanism (24).
12.19 Install tilt mechanism (24) in mechanism housing (17), ensuring spring actuator (30) engages
with needle bearing. Secure with two screws (23) and two screws (25), using Loctite 222E.
12.20 Working through the hole in the mechanism housing assembly (17), fully tighten the balance
mechanism screw (37).
12.21 Using Loctite, install cap (36) in hole in the mechanism housing assembly (17).
13 Install the remaining tilt mechanism components as follows
NOTE: Early brake shafts (to Serial No. 2945) are solid. Later brake shafts are fitted with spring
and friction elements (21 and 22) to improve performance. Early brake shafts should be
replaced by later brake shafts and spring and friction elements.
13.1 Install spring element (21) and friction element (22) in pan brake shaft (20) and screw into
outrigger (9).
13.2 Install spring element (21) and friction element (22) in tilt brake shaft (25) and screw into
outrigger (9).
13.3 Screw both brake shafts in as far as they will go and install a brake knob (16) on each shaft so
that, when fully applied the knob is vertical and, when turned fully counter-clockwise, the brake is off.
