Buck's BIG SCOPE Tune-Up

To Upgrade & Optimize Meade telescope drives

Upgrades drives in all 14-inch Meade LX600, LX200ACF, LX200R & LX200GPS telescopes built after February 2005 plus all RCX400 telescopes
Significantly improve mechanical precision of both AZ and DEC drive
Improve PEC and reduce mechanical backlash

This tune-up kit further increases the precision of your drives through a series of adjustments that Meade’s assembly line did not take the time to optimize or simply cannot make.

As an example of an adjustment – Meade’s brass gears may have been machined precisely, but that precision counts for nothing unless they’re properly meshed. Meade’s assembly line has no way of adjusting for proper mesh and they ship with some gears that are barely cogging (just touching tip of tooth to tip of tooth).

No one step will take your scope all the way to 1 or 2 arc-second tracking performance, but this tune-up is the largest single mechanical step that you can take in this direction.

Installation of this kit will:

1) improve the drive precision in both RA and DEC drives, reducing or eliminating transfer gear backlash.

2) correct other misaligned drive components, improving drive precision and eliminating the chance of incurring drive damage due to this misalignment.

3) If installed before the scope sees much use – allows you to detect conditions where extended use will seriously damage the scope, rendering the drive/drives inaccurate. We’re always hearing back from folks who’ve discovered loose screws or stripped screws, extra pieces of metal floating around in the gear grease, gears that are only cogging (touching tip of tooth to tip of tooth) instead of meshing, drives that are misadjusted, etc.

The kit contains step-by-step photo illustrated instructions for optimizing the declination and the azimuth drives, plus special gear grease, wrenches and parts to correct those scopes where the gears do not mesh closely but are only touching tooth tip to tooth tip in a cogging kind of action.

This drive upgrade is intended for scopes manufactured after August 2005 when Meade started using precision brass transfer gears in the drive train. The upgrade is actually a Buck’s Gears kit without the gears! DO NOT BUY THIS UPGRADE if you own a 7″, 8″, 10″ or 12″ Meade LX200GPS manufactured BEFORE August 2005 – Your scope has plastic gears and really needs the Buck’s Gears kit.

Although the instructions provided are crystal clear, this tune-up is more complex than the installation of the EZ Focus kit or the EZ Clutch kit. If you had trouble with either of our other kits, or if you consider yourself to be a klutz, please either do not buy this kit or arrange for someone else to perform the tune-up for you.
