Peterson Engineering 5" EZ Clutch upgrade Kit
Meade LX600,LX200ACF, LX200R, the RCX400 and the 14" LX200GPS scopes use a 5" diameter clutch friction plate.
This upgrade kit modifies the declination clutch system on Meade RCX400, LX200GPS, LX200R and LX600 families of telescopes. When installed, lightly tightening the clutch knob with two fingers is all that is required to hold even the most unbalanced scope firmly in position. You'll no longer have to turn the declination knob uncomfortably tight or risk having your knob popping off as you tighten it to it's breaking point. With the EZ Clutch you have enough "feel" that can easily dial in enough declination tightness to hold the optical tube firmly but still allow the drive to slip if you hit an end stop or an obstruction.
Meade's design utilizes a "wet clutch" system where two steel plates engage the aluminum declination drive gear. The space between these plates is lubricated to prevent the aluminum gear from galling and having aluminum chips falling onto the worm gear drive below. The EZ Clutch Kit converts Meade's clutch design to a "dry clutch," adding a specially developed friction plate to the system.
While the "obvious" fix was to add a larger knob (as was used on the LX200 "classic") Meade's new smaller "stylized" knob comes with a smaller weaker screw thread. Any machinist will tell you that you NEVER insert a steel adjustment bolt into aluminum, as steel abrades aluminum - causing the aluminum threads to wear out quickly. The aluminum scope trunnion section containing the female threads is thin, and there are usually only 3 full threads there to start with. The excessive force required to clamp the wet clutch plates leads to premature failure of the aluminum thread.* Since a larger knob would result in larger forces and an even more accelerated thread wear, we spent a bit more time with the engineering and developed this easy clutch modification. EZ Clutch forces are light and will prolong the life of this critical aluminum thread indefinitely.
The EZ Clutch installation procedure is simple, and the 4 page photo illustrated instruction sheet contains detailed step by step instructions.

"I just installed your EZ Clutch kit into my 12" LX200GPS and I'm very pleased with the results. This is what should have been done in the first place."
From the UK: Thank you for the prompt delivery of the EZ Focus and EZ Clutch kits. The instructions are very clear and the conversions only took about an hour to accomplish. The difference it has made to my LX200R is quite astonishing. It feels like a "new" scope, focusing is so positive now and with the dry clutch fitted all of the slippage problems with the Meade wet clutch problem have gone! A big thanks to you for your exemplary service and I can assure you that I am spreading the word on this side of the Atlantic for you and your products.
From Georgia: "The fix from Peterson Engineering is great! The instructions are clear and unambiguous to even an all thumbs kinda guy like me."
From Oregon: "I'm very pleased with how easy and quick it was to install the clutch. I'm also very pleased with the operation of the clutch..... The instructions were excellent. Meade should take a lesson from you on how to develop manual instructions."
"I must say, this was one of the easiest installations I have ever done. The instructions were well written, precise, and well illustrated. Applause to a great product!"
