22. INSTALLATION ON ENGINE: The propeller must be carefully checked
for track and balance before and after being placed on the engine. Oil the crank-
shaft splines and thread before the hub is installed. The hub nut should be screwed
up solid but must not be forced with a heavy sledge. Be sure that the clamping
ring bolts are cottered. For complete instructions see B. A. Technical Note
No. 189.

24. INSTALLATION (Reference Fig. 13 to 18 inclusive): The installation
of the oil system is very simple and presents no difficulties. Note that the oil
tank should be installed before the main fuel tank. Place safety wires on all nuts
and drain plugs. The oil lines must be bonded at all hose connections.
25. MAINTENANCE: a. Inspect the entire oil system at regular intervals.
Be sure that all fittings and connections are tight. Check the gages occasionally
to see that they register correctly. Check the operation of the relief valve.
b. Clean the oil strainers after every ten hours service or oftener.
c. The oil system may be drained by removing the drain plugs in the oil tank
outlet pipe and the engine sump.
d. Do not forget to replace any cotters or lockwires removed.
26. REPAIRS (Reference Fig. 16 and 17): The oil tank may be removed
through either side of the fuselage but the right side is preferable. Disconnect
all pipe lines, fittings and controls interfering. Support the main fuel tank
securely so that it will not move when the cradle is loosened. Loosen the
turnbuckle in the forward cradle strap, remove the clevis pins at . both ends of the
strap and remove it. Remove the oil level gage, loosen the tank support straps,
and the tank may be removed.
b. The oil tank is constructed of aluminum and repairs can only be made by
welding.
