| Subject: | Will an IO-540-C4B5 narrow deck work for an RV-10 |
I bought an IO-540-C4B5 narrow deck, and am planning to have it
overhauled. However, last night at an EAA meeting, someone told me they
heard narrow decks were no good, but could not offer why. I bought the
engine from someone who had been building a 10 but lost interest, and I
never considered the possibility that a narrow deck might not be
suitable, but I'm not certain why that would be.
Is a narrow deck C4B5 acceptable for a 10? I hope someone else has
one...
Thanks
Andy

Andy, I'm using an O-540-E4B5 out of a cherokee 6-260. Its a narrow
deck. I fits the engine mount perfectly. The only thing I remember
as being a question is which mounting tabs are on the engine. These are
easily changeable if you have the wrong ones. One note, I'm not using
Van's prepackaged firewall forward kit, I'm on my own for these various
accessories. Also, I'm converting to fuel injection via the airflow
performance conversion kit.

The concerns are mostly theoretical at this point. I don't know if
Lycoming still makes major replacement parts such as crankcase.
Cylinders should be no issue, along with most other standard
replacement items. Lycoming stopped making new narrow deck engines
about 30 years ago, but as far as I know they have been supporting
them pretty well.
In fact, they used a narrow deck engine for the certification mule of
an IO390 in a Mooney 201 this year, as it was on display at OSH. If
you can get a quality overhaul of the engine now, you should be good
to go for 15-20 years. On the other hand, Lycoming has refused to take
as cores for exchange engines of either variety that have not been
back to the factory for overhaul within the past 36 years.

While you're thinking about the relays, here's another one:
Are you isolating left and right grip controls with a switch on the panel? The
schematic that came with the relay board just shows both wired in -- assumes
only one pilot will trigger the hat switch? I've searched the archives and found
some with a pretty hefty selector switch.

The C4B5 is almost identical to the D4A5 Van's is pushing, primary
difference is a lower RPM rating creating 10 less HP. They are both narrow
deck so I don't know where the concern at the meeting came from. There was
a previous thread discussing the differences between the C4B5 and D4A5 that
you might want to search for. From what I understand it's the wide deck
engines you should shy away from.
FWIW I had a C4B5 on my Skybolt and it was great.

You need new ears to fit the standard Van's mount, Narrow Deck, from my
research, are less prone to cracking than the newer wide deck, Eci
provides great cylinders to go into these engines (expect to do baffling
work for the tapered cylinders) as does Lycoming you can run the engine
from 2525 @ 250hp to 2700@ 260 without an issue and in the end it's the
same engine.
If you need a great Overhaul shop let me know off list.
Bottom line, you'll be fine with what you have.

Yes, that is correct about the ears, I forgot about that. The Rocket
guys use the smaller ears and often have larger ears available.... I
was able to swap mine out (even trade) with them. You may have
similar luck with John Harmon or Mark Frederick, or with a posting on
the rocket or RV-4 list....

I think you have that backwards. My IO-540-C4B5 had mounting ears with
large holes and I had to swap them for ears with the small holes to
fit the engine mount.

Both engines are fine, cost the same to overhaul and will work in the
-10. The engine may/may not have a lightening hole crankshaft which is
fine but not suitable for aerobatics (shouldn't be a problem in the
-10.) The cases have a number of overhauls that can be done by an
approved facility and most of them will have cases if you ever have to
replace them. The only difficult major component to replace at this
time is the crankshaft. Used serviceable crankshafts are very difficult
to find at this time, and new ones are very pricey. OEM flat tappets
are also currently difficult to get but PMA are available.
If the -C4B5 came from an Aztec, the mounts will be the larger hole and
will need to be swapped to the smaller ear mounts.
If you decide not to use it, let me know. I'll by the core from you!
:-)
Good luck.
