Raymarine Rotary Drive-AutoPilot

[Chef Mike]

I have had some problems with the rotary drive for my Type 1 6000 Autopilot. Its the drive unit that uses a sprocket and chain that attaches directly to the rack and pinion system.

Within the rotary drive unit are a set of plastic planetary gears that attach to the forward mounting cover. At times these gears bind and in a couple of instances they have bound so that the machine screws holding the ring gear have failed. I installed one size larger machine screws to get it working again however the gears still bind up at times.

Raymarine claims that they do not carry a spare ring gear however have they do have the planet gears.

Has anybody had a similar problem and any suggestions for a fix?

Anyone out there have some spare parts floating around?
