Install P/N 821-2 spindle on P/N 520-6A shaft, drill and ream for the roll pin and install
the roll pin as shown in Figure 36.
Note: It is important for all of the screwjacks to be synchronized exactly. The springs on
the end of the screwjack sleeves will allow for some lack of precision in this respect, but
they will do nothing to help you when the gear is fully up.
The ideal situation is to have all of the screwjacks arrive at the full “gear up” position at
the same time. The only way to insure this is to install the screwjack sleeves and run them
all the way up until they bottom out against the universal joint. The screwjack on the left
side of the airplane is turned so that the gearbox’s shaft and gear is turned until the slotted
end of the screwjack sleeve is exactly vertical. Then the screwjack on the right side of the
airplane is turned to the same position (again with the screwjack bottomed out against the
universal joint) so that the slotted end of the screwjack is exactly vertical. (The same
procedure will be used for the screwjack for the nose gear to synchronize all three
screwjacks.) This is the reason for all of the following procedures.

❏
Install P/N 513-2 screwjack on the universal joint for the left side of the aircraft. See
Figure 37. This part has right hand threads. If you are unable to tell right hand threads
from left hand threads, just remember that this screwjack has the same threads as the nose
gear screwjack. The end of the screwjack has a short end to the shaft, shorter than the end
of the universal joint.
