Repair Beseler 35mm NegaTrans for 23C?

[Tony-S]

The rubber belt on my negatrans has broken. Does anyone know where I can get a replacement part and how to repair it?

TIA.

Some of the older hardware stores still carry selections of O rings you could match to the size of the broken one.

I would try the manufacturer, they are in New-Jersey, and their website is at http://www.beselerphoto.com/

The 35mm version is pretty easy to fix. Just a few screws and it comes apart and you can thread the belt/o-ring without too much trouble. (the 120 version has some more parts to remove inside)

I picked up an o-ring at a local hydraulic repair shop (think heavy equipment) they had thousands of types.

Take the old one and they can match it. I ended up with a 6X6-3/16 o-ring, cost a whole $1.44..

I've seen replacement drive bands for sale on evilbay.

Ouch, that's expensive. I found one on Ebay for $10, so it's the one I bought.

OK, I rec'd the belt today and put it in as best as I can tell is proper (see pic). However, it turns very stiffly clockwise and not at all counter clockwise. All the wheels turn freely. Can someone verify for me that I have the belt in correctly and suggest why it's not turning smoothly in both directions?

Thanks!

Did you check the new belt length to the old one. Just a couple of mm can make a big difference. Is the diameter the same?

[Tony-S]

Diameter is the same, but I cannot compare lengths because the old one was in pieces from age. Do the wheels need lubrication?
