A few of the rollers are missing from my Raymarine 4000 MKI autopilot. These rollers are the cone shaped pieces that are screwed into the back half of the wheel, and allow the front half that is clamped to the steering wheel, to turn. I called Raymarine last week and they said that parts for the 4000 MKI were no longer available. He suggested I send the complete wheel to them so they could see what, if anything, they could do to fix the problem. If they could not, they may be able to offer me a deal on an upgrade to a 4000 MKII wheel. Before I do that, I thought I’d ask if anyone has any rollers they would be willing to sell. Thanks.
