#126 or 128 roller chain

And that size means what? Go to the Tsubaki website and get your sizing right. There are two families metric and inch and many different strength, durability, speed and corrosion resistance choices. Speed, shock and the lack of lubrication kill chains. The very best chains are designed for motorcycles. They are in a class by themselves. Steve

I would think that tail rotor chains on a helicopter would be the best?

I'm fairly sure the size designation is the problem. The machine is vintage early 80's, someone put in either a very odd ball chain or there is some disconnect between the parts manual (whence the #126) and the real chain. Hmmmmmmmmm I wonder if it means **126 LINKS***?

The chain runs in a TERRIBLE environment, water, salt, dirt, rocks, occasional frozen deer, with large rotating mass and nasty shock loads. I suspect that a good motorcycle chain would be the ticket.

I've requested an actual measurement > And that size means what? Go to the Tsubaki website and get your sizing

Measure the outside width, inside width and the center to center dimensions of the existing chain. Then measure the sprocket width and the tooth spacing. Match those up to the sizes of the Tsubaki website. Steve
