(6) Pump

a maximum of 1 ﬂ. oz. (30 ml)

grease into the

lubrication fitting or u

ntil grease emerges from the hole

where the l

ubrication fitting

was removed, whichever

occurs first.

(a) Repeat for each blade clamp assembly.

(7) Reinstall the l

ubrication fitting

s on each blade clamp that

were removed at the beginning of this procedure.

(8)

Tighten the lubrication fittings until snug.

(a) Make sure the ball of each lubrication fitting is

properly seated.

(9) Reinstall a lubrication

fitting

cap on each lubrication

fitting.

C. Approved Lubricants

(1) For a list of lubricants approved for use in Hartzell

propellers, refer to the Consumable Materials chapter of
