The tailwheel assembly consists of a Maule SFS-P8 full swivel, steerable tailwheel and
a leaf type spring mounting. This unit should be lubricated as noted in the inspection guide
in the manual. Keep air pressure at 40 psi.
If tailwheel is a Maule SFS-P8B and if shimmy of the tailwheel becomes a problem, it
should be lubricated and adjusted as follows: (See Fig. 1 for detailed breakdown.)
A. DISASSEMBLY
1.
Remove cap (74B) - may be pried off with flat side of a screwdriver.
2.
Hold the fork (69B) and loosen the nut (A1).
3.
With the nut removed, carefully remove the fork spindle from the rest of the as-
sembly. Slowly rotate the fork back and forth while withdrawing it and collect the
loose parts.
4.
Clean all of the metal parts in solvent. Inspect all parts and replace any parts that
exhibit excessive wear.
B. SHIM SELECTION
1.
Position the bearings (A5) in bracket (71B) and slide the fork (69B) through the
bearings. Do not install any of the other parts at this time.
2.
Slide lock ring (73B) over the threaded end of the fork spindle and run nut (A1)
down until it bottoms on the lock ring.
3.
Tighten the nut moderately and note whether or not there is any end play in the
bearings. If there is no end play and no excessive rotational drag, shimming will
not be required. If there is any bearing end play, remove the nut and spindle and
install one (1) shim (83B) on the spindle and repeat the check. Normally only one
