This kit upgrades the declination clutch system on Meade LX600, LX200ACF, LX200GPS LX200R, LX400 ACF, RCX400 and LX90\u00a0 families of telescopes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The EZ Clutch Kit addresses three problems:<\/p>

1) The declination knob is hard to grasp, making it difficult to apply enough force to securely lock the declination drive.\u00a0<\/p>

2) Repeatedly tightening the knob with even moderate force can eventually cause failure of the declination knob engagement thread.<\/p>

3. On some scopes, due to load, the worm will lift off the aluminum worm gear chewing up a non-replacable precision gear.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

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.\u00a0 You\u2019ll no longer have to turn the declination knob uncomfortably tight or risk having your knob popping off as you tighten it to it\u2019s breaking point.\u00a0 With the EZ Clutch you have enough \u201cfeel\u201d that can easily dial in enough declination tightness to hold the optical tube firmly but still allow the drive to slip if\u00a0 you hit an end stop or an obstruction.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Meade\u2019s design utilizes a \u201cwet clutch\u201d system where two steel plates engage the aluminum declination drive gear.\u00a0 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.\u00a0 The EZ Clutch Kit converts Meade\u2019s clutch design to a \u201cdry clutch,\u201d adding a specially developed friction plate to the system.<\/p>

Meade\u2019s older LX200 \u201cclassic\u201d SCTs used a large easy to grip declination lock knob with a large engagement thread.\u00a0 Tightening the declination lock was effortless and failures were unheard of.\u00a0 The \u201cobvious\u201d fix to weaker declination locking was to add a similar larger knob.\u00a0 But Meade\u2019s smaller \u201cstylized\u201d knob utilizes a smaller engagement screw threaded into an aluminum female thread.\u00a0 Any machinist knows to NEVER insert a steel adjustment bolt into aluminum, as steel abrades aluminum \u2013 causing the aluminum threads to wear out quickly.\u00a0 The declination lock female thread is not only aluminum, but it\u2019s thin \u2013 there are usually only 3 full threads there to start with.\u00a0 The excessive force required to clamp the wet clutch plates leads to premature failure of the aluminum thread.\u00a0 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.\u00a0\u00a0EZ Clutch forces are light and will prolong the life of this critical aluminum thread indefinitely.\u00a0<\/p>

Sorry, but if your declination lock has already failed you need to talk to Meade or a machine shop as the damage is already done.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The clutch kit instructions include inspections and appropriate adjustments of the drive if factory settings are found to be incorrect.\u00a0 Here\u2019s a 5-1\/4\u2033 worm gear with minor tooth damage associated with an incorrect factory setting.\u00a0 This damage isn\u2019t discovered on some scopes until the teeth are chewed up so badly as to be non-functional.<\/p>

If your irreplaceable main gear has already gotten chewed up there is a possible fix has been developed.<\/p>

The EZ Clutch installation procedure is simple.\u00a0 The 4 page instruction sheet contains detailed step by step photo illustrated instructions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
