while turning the catch mechanism
to the vertical position and pulling the
catch forward.

until the catch mechanism locates in
the hole in the case, and turn the
catch lever to the horizontal position.
Disconnect each pump tube from its
respective tube connector at the rear
of the case, pull through the
grommets and discard.
Remove the retaining screw on the
pump shaft and remove the capstans.
Fit all three new capstans, from the
kit, on the hexagonal shaft so the
rollers are offset from one another.
Fit retaining screw.
If required, fit new pump tube
bungs and shims, from the kit, to
the left hand side of the pump.
Pass new pump tubes, from the
kit, through the tube bungs and
case grommets. Connect to the

pump. It is important that the
shims are always fitted.
Locate the tubes centrally on the pump rollers.
