C. ASSEMBLY
1. Grease pack roller bearings (A5) and lock pin (13AB) with wheel bearing grease.
Grease the parts adjacent to lock pin. Do Not grease friction washer (72B-4) or
the parts adjacent to it.
2. Place the roller bearings (A5) in their races, the felt seals (78B-2) on the bearings,
and the three (3) springs (76B) in the three deeper holes in bracket (71B). Place
friction ring assembly (72B-3) over the springs with the pin in the shallow hole in
bracket (71B). Grease may be used to hold the foregoing parts in place. Do not
allow any grease on the friction washer surface of the friction ring assembly (72B-
3).
3. Place shim(s) (83B) on lower shoulder of the spindle on fork (69B). Place the fric-
tion washer (72B-4) on the large diameter friction surface of the fork.
4. Carefully slide the fork spindle through the friction ring and bearings until the fric-
tion washer is bottomed against the springs. Make sure that all parts stay in
place.
5. Assemble lock ring (73B), arm (6) (with lock pin (13AB) and spring (14) installed),
shield (36), and pins (60AB) together as a unit. Make sure that the key end of
lock pin 13AB) is properly aligned with the slot in lock ring (73B).
6. Slide the lock pin subassembly over the threaded end of the fork spindle being
careful to keep the parts together. It will be necessary to retract lock pin (13AB)
slightly to clear wear plate (75B) as the assemblies are brought together.
7. Thread on nut (A1) and torque to 15-20 foot pounds. Fork should rotate by hand,
but with some drag, which is normal and caused by the friction washer.
8. Install cap (74B) with soft mallet. Check wheel rotation. There must be no play in
the bearings. Wheel should rotate with a slight drag.
D. TAILWHEEL INSTALLATION
1. Check all bolts and nuts holding the tail springs to the fuselage. They must be
tight so that there is no play or side movement in the springs or their attachment.
2. Tighten the bracket bolt and back off enough to install the cotter pin. There must
be no looseness or play between the bracket (71B) and the spring.
3. Install the connector springs, using the heavier spring on the right side. Install the
springs so that the light spring is compressed approximately 1/2 to 3/4 inch.
