12. Once you are certain that the crank arm and triple
cam are properly aligned, place a center punch in
the centre of the crank arm shaft (on the side with
the plastic crank arm), and give it one or two taps.
If the two are properly aligned, the crank arm will
easily couple with the triple cam.
13. On the other side of the brewer, secure the crank
arm to the brewer mainframe using the c-clip that
was removed earlier in this procedure.
14. Insert the crank arm pin through the front of the
piston rod and through the crank arm. It may be
necessary to raise or lower the piston in the cylinder
to properly align the two. Secure it in place by
inserting a c-clip on the pin at the rear of the crank
arm.
15. Insert the drive pin into the crank arm shaft at the
rear of the brewer. Note that the pin is tapered (one
end is thicker than the other due to three splits
added along the pin’s sides).
Insert the thinner end (without the splits) into the
crank arm shaft, and then tap it a couple of times
with a hammer to wedge (press-fit) the pin in place.
16. While pressing down on the H-frame, insert the
T-bar from the top of the brewer down into the
threaded section of the T-bar housing, and turn the
T-bar approximately 20 turns clockwise. Once
done, install the T-bar into its recession on top of
the H-frame.
NOTE: You have now successfully re-assembled
the Zuma brewer, You must now re-adjust the
brewer chamber’s tension. For the procedure
for adjusting the brewer tension see chapter
1.3.2
Adjustment brewer chamber tension.
