Yesterday afternoon I performed the Declination clutch upgrade on my RCX400. The upgrade basically involves removing the clutch plate, cleaning off all the grease, installing a piece of cork to act as a 'dry clutch' and re-greasing the gears.
The instructions were well written and I had no problems. It took me about 80 minutes to do the whole thing (longest part was removing all the old grease from the various parts).
Since the pictures in the instructions were from an LX200 and weren't of the highest quality, I took a series of shots and have posted a guide to the upgrade.
This particular picture was taken after installing the cork and re-greased parts. At this point all that was left to do was test it out and put the cover back on.
With the upgrade the clutch seems to work a lot better and doesn't require me to over-tighten the Dec. knob in order to avoid slippage.
