Cliff;
For the propellor =93 Many years ago (25+) Shell stopped producing
Aeroshell Grease 5 which was the Hamilton Standard spec. for the
counterweight type propellor (2D30, 12D40, etc.) So most overhaul
facilities reverted to Aeroshell 6. A few years later the demand for
Grease 5 was so high that it was produced under the ROYCO name and then
finally back under Shell.
Check the Aeroshell specs. for 5 & 6. You will find that Grease 6 is an
=9Ceconomical=9D general purpose grease. Its load carrying
abilities are limited and it=99s upper temperature limit is
extremely low. The blade bearing rollers and races in the type of
propellors we are dealing with require a high load bearing grease such
as Aeroshell 5.
This may be more critical for HS counterweight types than for the
Russian/Chinese variety since the blade turning torque is set much
higher. - 50lb/ft vs 8 lb/ft.
For the landing gear Grease 7 is fine but so is Grease 5. Why add
another grease gun?
For the pneumatic system I agree.
Cheers;
Walt

For the wheel bearings: Aeroshell #5
For the propeller: Aeroshell #6
For the landing gear and other moving/sliding assemblies: Aeroshell #7
For the actuators and other air components we use MIL-G-4343 Pneumatic
System grease. it can be found as Aeroshell #43 or Royco #43 or Jet Lube
#33.
Cheers,
Cliff

If you are referring to grease I use and recommend Aeroshell 5.

basic lube question
<pednicholson@gmail.com>
Gentlemen,
Could you advise what grade of lube you are using for landing gear
etc. Anyone using synthetic? What commercially available tool are you
applying the lube with?
Thanks,
Phil

*Good afternoon Walt,
You're absolutely correct- it's all about the grease guns! *grin*
Hartzell propellers are manufactured and serviced with Aeroshell #6 and
does not recommend mixing of greases.
Therefore we have one grease gun labeled for propeller use only.
We have one grease gun with Aeroshell #7- which is a general purpose grease
approved for damn near everything.
We have a bearing packer filled with #5 which is recommended by Aeroshell
for wheel bearings.
Since we service over 60 aircraft a year and these greases are approved for
the applications for which we use them, it's simpler to use the "5,6,7"
rule in most cases.
Best regards,
Cliff
