| Subject: | Ultrastar drive belt |
The drive belts on my Cuyuna powered Ultrastar are a pair of 280J10 poly-v
belts. These are no problem to obtain, of course, but using a pair of
belts like that isn't always the greatest idea unless they're exactly
matched, preferably from the same production lot. It occurs to me that a
single 280J20 belt (same belt, twice as wide) might be a better choice...
it's harder to find but it IS available. The original US manual refers to
two belts, though... I wonder why? Could it be just availability? Or
some other reason? There's no real difference; the belts are manufactured
very wide and slit to the required width.
A 220J20 belt is $23, while 220J10's are $19 each... though I have an open
account with McMaster, who stocks the 10's but not the 20's...

I talked to Homer Kolb last summer about my VW belt drive. He told me he had
a tool that measured belts. He had to pair up the belts from a shipment of
belts to make sure that the belts were the same size.
When I changed from cog belts to the serpentine belts I currently use there
was some loss of power but the serpentine belts don't transmit the nasty
harmonics the way cog belts do. Well worth the trade off.

Mine's the poly-v, sometimes called a serpentine belt (though "serpentine"
correctly refers to how a long belt is routed on a car, not the belt type
itself). Any other type of belt would require different pulleys.

If by cog belts you mean timing belts (synchronous belts), then yes you can
get vibrations. Same thing with a gear drive, which is why a gear drive
often has some kind of slip clutch or harmonic dampener. A friction belt
(either a classic V-belt or a poly-v flat belt) lets it slip a bit,
dampening out the power pulses.
Of course too much slip and the belt wears prematurely.
One other advantage of the poly-v belt is that unlike a timing belt, it
rarely fails suddenly... ribs start to disappear and it's quite obvious
during preflight, but it will still transmit power. When a timing belt
goes, a bunch of teeth come off and you better have a landing spot handy.

Yes. That's what they say. I have never tried just one belt and don't plan
on it. They sent me used belts so that I would be able to fly to Oshkosh
last summer with out having to play with run in adjustments. I have put only
47 hours on them since then. I don't have a clue of the cost.

Curiouser and curiouser. Thanks, George. I would love to know this history on mine.
The closer I look, the stranger it gets. I have the Ducati ignition, and
I do have a serial number on the engine. It does look original, but who knows.
Once I get it to the airport maybe somebody will know more.

Hope you have better luck than I had. Actually I know three owners back
for my plane, but the first guy I know (who bought it sometime in the early
90's) doesn't remember the original owner's name, only that he "was an old
guy" and probably dead now. Of course mine is mostly stock so there aren't
many questions. Of the three owners I know, only one ever flew it (and he
only flew it a couple of times), though some of their friends flew it
occasionally.
