Sankyo_gatemask_removal

You will need a small set of precision screwdrivers for this job. Remove back cover.
Remove 3 Claw and terminal strip mounting screws.
Move the terminal strip to the side

Remove lubrication post.

Slide FRAMER all the way down.

Remove the claw mechanism by grabbing it from the back and pulling a bit to the left and then out.
Do not tapply any force. You should be able to wiggle it out.


Pop the belt off the cam.
Remove cam bushing mounts and the lubrication felt pads.
Remove heat shield and lamp mount screws.
Push the lamp mount to the side.
Remove the heat shield.
This exposes the mask components.

Remove heat shield

Place all removed components on a white piece of paper and if necessary
mark what they are.

Move the shutter wheel a bit to the back to expose the mask components and the mounting screws.

Study the image a bit and get familiarized with the components and what they do.
Also, this is a tricky part and it is easy to damage the sensitive components during the removal procedure.
Take your time and use small precision screwddrivers. Remove the lens holder



Loosen the flap screw.
Actually, do not do it the way it is shownn in the picture. Press with the finger where the screwdriver points and loosen the nut
from the opposite side.
Do not remove the nut all the way. The little spring will pop out and dit is a pain to put it back in. We just need the flap to be loose so that the mask cover can be slided out.
Remove the mask cover screws. Watch out for those copper washers and the flap stopper.
Slide the mask cover out.
Remove the gate mask.


Tighted the flap nut. Mount the heat shield back in and the lamp mount.
Lubricate cam bushings and install the felp pads back in. They go into a recess between the bushing and the mounting post
not under the bushing. This could throw your cam alignment off.
Slide the claw mechanism back in. Double check the image to figure out where it goes. This one is a bit tricky.
Do not force anything. The claw may bind a bit at the front. You can wiggle the assembly a bit to the left and that
will free up the claw.

Slide the claw assembly in. You need to open up the assembly a bit against the spring so that the claw level sits on the
can hub and the bottom frame alignment post gets engaged with the framer control lever. Also check the mounting tabs on the assembly. They should be over the mounting posts if the claw assembly is in properly.
Screw the assembly in using the mounting screws.
The top mounting screw is shared with the terminal strip. The strip mounting tab fits on top of the claw assembly tab and then teh washer goes on top
of that. Do not forget the 2nd terminal strip screw and the belt.
This completes the procedure.
