19.11 Position the base housing (1) upside-down on the bench and install the assembled pan sub-
plate, ensuring pan drag cut-out aligns with base knob boss, holes align with holes in base and the 'O'
ring (4) on brake boss locates correctly in base.
19.12 Lightly lubricate thrust race (27) and thrust race upper bearing disc (16) with LM grease.
NOTE: Do not allow grease to contaminate the braking surfaces of the brake disc (19).
19.13 Position thrust race on assembled pan drag mechanism and thrust race upper bearing disc on
pan sub-plate.
19.14 Position brake reaction plate (22) over four-hole mounting plate (20) and align holes in reaction
plate with those in drag plate subassembly.
19.15 Lower the assembled pan drag/brake mechanism into the base, ensuring that the pan drag
actuator gear (Item 17.1, Fig 5.1) engages cleanly with the idler gear (10).
19.16 Install the pan brake reaction assembly (22) and secure with four 25 mm long screws (23) and
three 20 mm screws (24) noting that longer screws are installed to the rear of the base.
19.17 Install the pan bearing nut (47) and tighten to remove any play in the bearing.
19.18 Lightly grease two dowels (46) and install in the base (1), ensuring dowels are flush.
19.19 If removed, install pin (43) and bevel gear (44) on drag knob shaft (35) and secure with Loctite
638.
19.20 If removed, push dowel (37) into pan drag adjustment disc (40) so that dowel projects 4.25 mm.
19.21 Install circlip (42) and washer (41) on drag knob shaft (35). Pass shaft through pan drag
adjustment disc (40) and install dowel (29) temporarily.
19.22 Lightly lubricate bevel gear shim (45) and contact faces of bevel gear and drag knob shaft with
LM grease. Install bevel gear shim on drag knob shaft
19.23 With the dowel (29) horizontal and dowel (37) in the pan drag adjustment disc facing forwards,
position assembled pan drag knob shaft in base, ensuring end of shaft locates correctly. Secure lightly
with three screws (28).
19.24 Position drag knob boss (30) on shaft (35), then fit drag knob (34) so that '9' on knob is adjacent
to mark on base casting. Turn the knob counter-clockwise to '0', then adjust position of pan drag
adjustment disc (40) so that the stop prevents further counter-clockwise movement. Remove the drag
knob and fully tighten screws (28).
19.25 Refit the drag knob and ensure that full travel from '0' to '9' is possible and that full drag is applied
at '9'. Re-adjust the pan drag adjustment disc (40) as required.
19.26 Remove the drag knob, drag knob boss and dowel (29).
19.27 Lightly lubricate two springs (39) and two steel balls (38) with LM grease and install in the pan
drag adjustment disc (40). Install drag detent ring (36) and secure with dowel (29).
19.28 Install knob boss (30) on shaft, engaging slot with dowel (29). With drag set to minimum, fit drag
knob (34) over boss so that '0' on knob is adjacent to mark on base casting. Secure knob with washer
(31) and screw (32). Install bung (33).
