40.10 Swing a friction shoe assembly (144) outwards, fit an actuator rod (with each end lubricated with
Vinten Fluid No. 3 into its location in drag actuator shaft (230) and swing friction shoe assembly (144)
inwards locating outer end of drag actuator rod (151) in the cup in friction shoe assembly (144).
40.11 Repeat Para 40.10 for each actuator rod (151) in turn.
40.12 Assemble friction shoe carrier sub-assembly (228/231) into pan drag housing (226).
40.13 Fit omniseal (153) into pan drag housing (226) recess adjacent friction shoe carrier-top (228)
ensuring that the seal is not distorted or damaged.
41 Further assembly of the pan drag unit sub-assembly should be performed over a shallow tray to catch
any spilt fluid. Continue as follows (Fig 6.9):
41.1 Supporting the pan drag unit sub-assembly with drag actuator shaft (230) square end
downwards, introduce Vinten Fluid No. 3 into drag housing (226) ensuring the fluid fills the spaces
within friction shoe carriers (228/231). This is a slow process and sufficient time for fluid settlement
must be allowed. The chamber must be 3/4 filled.
41.2 Fit ’O’ ring (232) in the peripheral groove of pan drag housing (226).
41.3 Check fluid level in pan drag housing (226).
41.4 Press push-on cover (233) over pan drag housing (226).
41.5 When lubricant has ceased to flow from central bleed hole in push-on cover (233) ensure cover
is fully seated and screw M3 Posidriv pan head screw (236), secured with Blue Hylomar sealant, into
the bleed hole.
42 To assemble the pan drag unit assembly proceed as follows (Fig 6.9):
42.1 Locate spirol pins (300) in friction shoe carrier-top (228) into their locations in pan unit top plate
(224).
42.2 Secure friction shoe carriers (228/231) to pan unit top plate (224) using four M4 socket cap head
screws (41) removed at Para 36.5. Retain screws with Loctite 221, used sparingly, ensuring this only
contacts the threads.
42.3 Secure pan drag housing (226) to bearing housing (221) with two M4 pan head screws (227),
removed at Para 36.6, in diametrically opposite holes.
Refit
43 To refit the pan drag unit assembly proceed as follows (Fig 6.2):
43.1 Fit brake segment assembly (6) removed at Para 35.4 onto spigot of pan brake actuator shaft
(69).
43.2 Align pan unit top plate cut-out with brake flange assembly mounting position, and offer pan drag
unit assembly (3) to the underside of primary mechanism assembly (2).
NOTE: The open side of the seal must be towards the fluid chamber.
