installed) in place. See Figure 42. Be sure you install the screwjack with the left hand
threads on the right side and the screwjack with the right hand threads on the left side.
Use shims, clamps, or any other means to hold the shaft in position. The universal joints
must have a snug fit against the inner race of the ball bearing, since this is what holds the
miter gear in position. Remember, the screwjack on the left side of the airplane has the
same threads as the nose gear screwjack!
❏
Drill through the universal joint for the left side of the airplane with a 3/16ӯ drill, then
ream with a Brown and Sharpe No. 1 tapered reamer. Observe the note and warning
above for the installation of taper pins.
❏
Install the taper pin with the required hardware.
❏
Check the gear for smooth running. If necessary, the end of the universal joint may be
sanded or a shim may be placed between the universal joint and the bearing.
❏
When you are sure that the shaft is properly aligned, turn the screwjack on the left side of
the airplane so that the screwjack end fitting’s slot is exactly vertical (check to make sure
that the screwjack sleeve is still bottomed out against the end of the universal joint).
With the screwjack sleeve for the right side of the airplane similarly bottomed about, turn
the screwjack so that the end fitting is exactly vertical. Clamp everything in place. Drill
and ream for the taper pin for the universal joint on the right side of the airplane. Observe
the note and warning above for the installation of taper pins.
❏
Install the taper pin with the required hardware.

Install P/N 821-3 collar on the upper part of the shaft.
❏
Install P/N 820 crank on P/N 821-3 collar. Check for fit. You will have to file a radius on
the tang of P/N 820, and you will have to file on P/N 820 or P/N 831-3 to make things fit
completely. Sand or file for final fit.
❏
Install P/N 822A handle on P/N 820 with the required shoulder screw and washer. See
Figure 43. The shoulder screw should be installed with Loctite, but first check to make
sure that the handle will turn freely with the shoulder screw tightened all the way. If
