'Tom,

I could be that the angle is used to deflect the exhaust away from the cowling I have not noticed the difference but I do not know allot about Rangers

John,
I did get a member to sell and is sending me an exhaust set with
about 150 hours on it. That solves a big problem, but another
glitch has come up. While removing the exhaust port aluminum
spacers, I noticed the "stamped" serial number and the name "ALCOR"
on the cooling fin were not located in the same position in relation
to each other. . It must be important because there is a very
slight angle difference to the face that mounts to the exhaust
manifold. That could explain the three burnt gaskets found at the
bottom of the spacer where the exhaust manifold flange hooks up.

I find no information on how these spacers are mounted.

Interestingly, the parts manual says of the six spacers, two are
supposed to be stamped part number #6614 and four stamped #6616.
Mine are all #6614 . Can you or another member help me figure this
out..

'Mike,
I'm still looking for information on the spacers and the mounting
sequence, but I can at least tell you my three gasket leaks were at
the lower gaskets were the collector tube (exhaust manifold) attaches
to the lower end of the aluminum spacer. I really don't see any
warping of the spacer faces, BUT the attachment flanges of the
collector tube are all bent to shit. I decided to trash it. The only
thing I can think of that would bend them like that would be a
disregard of any correct tightening sequence and/or torque. I got
new gaskets from Fresno Airparts. They're copper/asbestos and not my
first choice. They'll have to do. I don't know anybody that makes pure
copper He-man gaskets for the Ranger. Talk with you later, when I get
a little more information. Gasket leaks are unacceptable. (also
thanks John)

'As I recall the two "short spacers" R1625, go on the No 6 and
No 1 cylinders. There is a difference in length

between the baffle pin casting. The short end goes inboard on No 6 and No
1, the other 4, R 1624 "long", go in between

the other cylinders and all must be lined up so the baffle pins align all
the sheet metal. The air box must fit tightly. The

pipes are the last parts to be installed. The adapters want to fall off
and the lower part the exhaust surround cannot

be installed be for the engine is in the mount. I put a nut and spacer on
one side of the studs. Maybe I will pull the air

box cover on mine tomorrow and confirm what I remember. Good Luck, Bob
Haas.

'Bob,
If you get a chance to check that'd be great. I don't think you have
to take the air box door off though, but I would like to know if when
looking up from below, into the bay area where the exhaust stacks are
nestled, can you see the trade name "ALCOA" embossed on the bottom of
each spacer fin, or maybe you have just a part number. What I'm
looking for here is, if the name or numbers are readable to you, or
are they inverted to your point of view. Huh! I just reread what I
wrote and I think I'm loosing my mind. I've been working so long on
this bird, I'm begging rides with my friend in his Tripacer just to
see what it feels like??.
Tom'

'Tom,
I don't have any spacers that came with my F24. Could you send some
information and possibly pictures? My e-mail is bhpowell@gvtc.com
Thanks, Buell Powell

'That's odd . It'll take a couple of days to take a few photos. I'll
send them by the club here, or personal email. My Tempco R46 came off
the line with a C2. I have C5 installed. That occurred 1985. I might
have confused the issue by using the word "spacer" that may not be the
right term, anyway I'll send a picture.

'Thanks Tom,
The engine that came with my project is a C-5. I don't think it
was ever installed on this airplane-it's still in a box. I have the
manifolds for it but I haven't seen any spacers so pictures of what I
need would really help.

'Gentlemen the parts in question I believe are called Adaptors, long and
short. Part No. 6614 long and 6615 short.

Quote "Ranger Parts Catalog Ranger Aircraft Engine 6-440 C -2-3-4-5 Figure
8 page 12 No, 24 and 25." The shorts

go on each end cylinder, the longs on the inner 4 cylinders. You will note
the adaptors convert oval exhaust ports to

round ports which match the exhaust manifolds. In the casket set you will
find 6 each of the copper clad gaskets

to fit. This is why the studs on the exhaust ports are long, to accommodate
the spacers or Adaptors. If you need any

I have some in stock, clean but used. I'll be at Sun&Fun next week on the
Warbird line. Bob Haas.

'Hi Bob,
Thanks for the information. How much do you need for the
adaptors?

'Recently someone asked about replacement exhaust pipes for the Ranger engine. Mike Kelly heard from 5 or 6 folks that wanted a set and contacted a shop that would produce them - Aerospace Welding in Eagan MN.


Since I was in the process of replacing a cylinder on my engine Aerospace started on my set. They arrived yesterday and look great!


They are made of stainless steel (a stamp on one piece is 4386-10T) that measures 0.048 thick.


I'll post 3 pictures on this websites photo section.
