Paul,
I noticed the Reno Racer drawings on the ACRE website listed the Bell
final
drive as having 3.1:1 ratio. Perfect.
I am trying to contact the different sources you provided to get an price
on
them. I would appreciate it if you knew what a ball park figure would
be.
I
still have to find a way to mount a C/S prop to it and supply oil through
the shaft. It appears the Reno Racer had those types of props.
Cheers

Be aware there is a lot of adapting to do. I have no idea on the pricing
of the parts. Yes they are constant speed props but are were locked into
pitch position. They did not function as constant speed props.
They functioned as fixed pitch props.

Doug,
I would hazard a guess and say the Bell final drive looks similar
in size to
the Mistral planetary.
I would be very interested to know what the price was as well.
I contacted someone here in Australia and they wanted to know WHICH final
drive I was enquiring about - that's as far as I got! So I assume from
this
there is more than one model.

Oh no the Bell 47 is a LOT BIGGER. Bell engineers figured 1000 HP at
6,000 RPM input.

Bigger may not always be better, has anyone considered surface
speed on the large gears???
Ken
The Bell engineers must have known about that.

But what continuous rpm are they running them at and what is the
horse power loss is there slinging them bigger gears and pushing the
oil through them, as an eyeball engineers point of view it just looks
like a concern and at some point big is going to be to big for our
use and where is that point.

I did not notice anything when I was running it up at Sun & Fun
at 45 inches of mercury. The 350 HP turbo charged 12A was blowing the
trees down. Sure was strong. It is probably a more efficient box
than average as it is precision made. Note the pitch on that prop.

If you give me Dave Garber's contact info. I can call him up and speak with
him about the box.
Ken do you have a price on those Dodge gear sets now? For your info this is
the RX4 semi automatic bell housing with the large bearing in the middle
looks like attached. If I go with the Dodge or Allison set I will add the
front housing and bolt some type of thick machined plate to the front of it
as well to hold the bearing. I am back to electric props I guess:)

I don't have Dave Garber's phone number. But I think he lives on
Park Holland Road in Leesburg Florida.
A White pages search in Leesburg did not find a phone number.
Try sending email to Tracy Crook. He may have it.

I paid $150 for the Dodge gear set but the price has gone up a bit
since then, also I cannot find the clutch hubs that slide onto the
sun gear new but I do have a source for used ones, the new ones are
in the parts books but they just don't carry them as they just don't
wear out, the cost on the new hubs are $150 if they had them which
seems a bit steep as that is what the whole gear set costs.
Wow can you cut those file sizes down a bit as that one took 25
minutes one my slow dial up connection, wish I could get high speed
but I live way out here in BFE.
Ken
Ken,
Sorry with my new camera 1 MB is the small size. I'll try to use the old
camera for these picts or figure out how to use the Japanese compression
format. Ken could you do me a favor and tell be measurement from the
outside flange of the sun gear mount to the start of the sun gear.
Thanks
Doug
