Rotary Drive Type 2

[Navicula]

Hi I have a rotary drive type 2 for my hunter sailboat and I need the sprockets and chain to complete my installation....

question

who supplies the chain and the sprockets

and what info do I need to know, so that I get the right size gears (teeth) to work with a EV400 sail

is there anything else I need to know would be a great help

Thankyou

I would imagine Raymarine would have all the pieces to build your set up. Have you asked them?

But Edson has a SS chain they sell and some sprockets too. But you may have to have them bored to whatever size you need.

If gears and chain are all you need look at Grainger or similar suppliers. Most installations use motorcycle chain. Beware of stainless steel chain.

I completed a rotary drive installation this spring. Bought the small sprocket that attaches to the drive from raymarine. Then I ordered the chain from a company specialised in chains. It was a UK standard chain mainly used in transmissions on motorcycles I think. Then I ordered the sprocket that go on the steering wheel from the steering system manufacturer ( in my case Lewmar/Whitlock). They had drawings for my boats system and knew exactly what I needed.

To know which raymarine sprocket size to order you count the number of full rotations on the steering wheel from hardover to hardover. Then you can check a graph in the ray user manual what sprocket you need.

Good luck
