Front bayonet plate
Front plate reassembly
Fit the four bayonet tongues (103439) and secure with
eight screws (820425).
Fit the release button return spring (21096) with one
screw (820015).
Behind the front plate glue the two sponge seals
(13212) and (13213) as well as the foils (22829) and
(22832) into place.
Place the lens catch lever (103440) in position and fit
the cover plate (105107). Secure with screw (823440).
Install the spacer (810409) and the spring (816858).
Secure the second screw (823440). Check the lens catch
lever for ease of operation.
Front gear (30383)
Check the front gear ease of operation. The long shaft
from the drive gear wheel to the bevel gear wheel
sometimes has too little play which can give rise to
tightness. A light blow with a plastic faced hammer on
the cog wheel end of the shaft will generally overcome
the problem.
Fit the front gear on the front bayonet plate using one
screw (823019) in the front and one (820018) from the
rear. Check the freedom of operation. Do not tighten
the screws to much.
Centring the front gear key.
Mount the tool 902658 (V-2075) into the lens bayonet
plate and connect tool 902918 (V-2219). Turn the key
using 902918 to a vertical position. Check that the free
play is even in both directions. If there is more
resistance at one direction than the other move the front
gear to obtain a balance. Carry out the same procedure
with the key in a horizontal position. Also check at the
180
o
points in both vertical and horizontal position.
When the key is centralised tighten both screws in the
front gear and secure with safety lacquer.
