[C320-list] ST400+ Clutch Problem

[Warren Updike]

It feels strange when I engage it.  Each time the wheel is turned to starboard by the system the clutch handle lifts slightly.  After a few stbd motions, it finally disengages.  I need my autopilot.  I'm too cheap to by a new one and want to squeeze the last drop out of this one, especially since it doesn't seem like a monumental problem.

There was a wheel service kit, Part #D169, but Raymarine tells me they no longer carry that part.  I can return for factory repair for a max fee of $225; but, must consider whether to put the $225 towards a new system or repair this one.

Any advice on this greatly appreciated?

The manual says a special tool is needed to open the wheel ring.  Anyone done that?  Am I going to need new parts?

How about anyone who has done the upgrade.  Might you still have the old black wheel ring from the ST4000?
