TAILWHEEL MAINTENANCE
Once a year, disassemble tailwheel assembly and
inspect roller bearings:
1. Remove dust cap (2) from top of tailwheel
assembly (1).
2. Remove cotter pin (3) and slotted hex nut (4).
3. Remove wheel fork (10), bearing cones (6) and
remaining hardware from assembly.
4. Inspect bearing cones (6) and bearing cups (7) for
wear and replace if necessary. Replace seals and
washers as necessary.
5. Pack bearing cones (6) with a good grade wheel
bearing grease.
6. Install wheel fork (10) bearing cones (6) and
remaining hardware into assembly as shown.
7. Set bearings by torquing hex nut to 26 lbs-ft. All
bearing free play should be removed.
NOTE: Proper bearing adjustment is essential to good
bearing life. If bearings are loose, caster wheels will
wobble and/or slap side to side. If bearings are over-
tightened, loosen hex nut and rap shaft with a lead
hammer to loosen bearings. Readjust bearings until
proper setting is obtained. Figure 7. Tailwheel Assembly (Typical)
