Where does one find a free 540 service manual on-line for download?
I need to print one for the shop.
Thanks

I appreciate everyones input on this and am sorry I haven't got back to everyone
sooner but work sometimes buries us to the exclusion of all else.
I have pretty much (after a great deal of input) come to the same conclusion as
Mark in that I think it is propwash from that long 2 blade and will probably
soon opt for a 3 blade conversion.
That brings up an entire host of new issues ie: which prop.
And what are the thoughts of an engine "taking a set" to a 2 blade and not being
convertible to a 3 blade after so many hours.
Again thanks for all the input.
Milt

Hi Milt,
A 2 blade propeller has a 2nd order harmonic. The 3 blade propeller does
not have this 2nd order harmonic. The harmonic doesn't "take a set". It's
there with 2 blades, and not there with 3 blades.
I have two Rocket 3 blade MT propellers listed on my website in the "New &
Used" page under "Propellers". One standard propeller and one aerobatic
propeller.

Jim, respectfully that is not true. This "thumping" vibration is
still present with the MT installations, though it is diminished. It
is smoother no doubt but it is inaccurate to say that the "thumping"
vibration goes away with the MT. That has been my experience with it.
My 180hp RV with a Hartzell is smoother than a 540 with an MT in a
Rocket.
Regards,
Bob

Hi Bob,
Then the "thumping" isn't a 2nd order engine harmonic.
On a Lycoming 540 engine in a HR2, I've experienced the 2nd order harmonic
with a two different 2 blade propellers and the lack of the 2nd order harmonic
with a 3 blade propeller.
"Thumping" can be almost anything. I wish you luck in isolating the
"thumper".
(If it's airframe related, it will eventually fatigue and break. If it's
engine and airframe related, there should be chaffing marks showing up. Best
to find it first.)
Regards,
Jim Ayers
