   Didn't Jens or somebody here in RAS find the Chinese manufactuer of the
pots?  It wasn't that long ago they were talking of this.  Maybe google
groups will pin it down.

Damn Jone, you're good.....If that is not the series of pot in my pedals,
then I'm Elmer Fudd. Can is the right size, shaft (flatted) and mtg bushing
look right, the drawing appears exactly as the pot in the pedals appears, if
it had the flatted shaft.My memory is not that good, tho it appears that
Logi used the same pot for gas and brake, mounting tab location may be
different between the two. If I need to open the pedal base again any time
soon, I'll be sure to note any differences and let y'all know. Meanwhile, my
fingers are crossed, that my repair lasts this whole 4 day weekend here in
the states. Happy Turkey Day!
Thanks, Ed

Jone, spark, the pic of the series 295 pot shown on the page from the above
link looks almost exactly like what I saw in my pedals, I would say from the
pic and the tech description from the previous link, that this is almost
definitely the pot.Close enough for me to go check the price, right now.

Let us know what you find out.  I know Digikey cares CTS but not sure about
that exact one.

That was prob me, I contacted the mfg (CTS) for replacements for the
original logi pedal pots and got a quote but had to purchase from China
in multiples of 1000 pcs.

They were a special made only for Logi, as I suspect these are too. Not
that it should stop anyone with the will from finding a suitable
replacement<S>

Cheers.

Is the Momo steering pot the same as the pedal pots?  They were on the older
LWF & LWFF.  If so, I'd think you could just get pedal pots from CH, since
they're the same shape and work fine wired into the Logitech harness.

Do you know exactly what the difference from one of their standard pots was?

older

No.

This looks very much like the steeringpot:
http://www.ctscorp.com/electro/251pot.htm

And this one could be the pedal pot:
http://www.ctscorp.com/electro/295pot.htm

The last one has the same mechanical dimensions, I suppose it could be a
replacement even if the one Logi used is a special version. Logi used 30k
but 30k is not available in the standard range.

The steering pot however is more suspicious, as it's standard range is only
available in a rotation angle of max 110 degrees. So Logi must have gotten a
special version of this pot, or is the pot geared down inside the momo? If
it's directly connected to the wheel axle, it has to rotate close to 300
degrees.

Spark gave it to me Elmer... Ehh Ed!

The pots are the same they are just mounted in opposite directions.

I seem to remember (cant find my notes) that there was no threaded
attachment flange, it was plain and the resistance was not progressive
throughout the pots total movement but lots of resistance change for a
small movement of the wiper in one area. The pedal pot you indicated
seems to meet those requirements but has anyone found if CTS will supply
small quantities?  Having said that I am told the CH pots appeared to
work in the pedals ok for the older LWff.

Just a stupid idea but, if the  pot is only used on through a small part of its
total rotation capability, isn't there a way to rotate it and use it through a
new "'clean" portion  of its track?

No. It rotates 300 deg mechanically, but only 50 deg electrically. They call
it effective rotation, the era of the pot where rotation has an electrical
effect. If you move it past these 50 degrees, the input from that pedal
would probably be either at min or max no matter if you pressed the pedal or
not.

Ed,
I haven't seen the Momo-pedals inside yet, but...
A nice trick on the LWFF pedals was to exchange throttle and brake pot. The
slider was then operating on a fresh layer of whatever-wears-out-there.
This will double your pots lifespan, if they are not damaged by your spraying.

I've made my own pedals, and wired them to the
new momo wheel.     What I've found is that you
dont actually have to use the full rotation of a
pot to get something up and running.
Frankly, my pedals dont turn very much at all...
maybe 10 or 20 degrees at the most, and with a
normal pot, thats not a hell of a lot of change
of resistance, but you can nevertheless calibrate
it and run GPL fine.
So if all else fails, just plug in a normal pot
rather than try to hunt down the momo specials.
