Bucks Drive Tuneup for 7-12" LX200-GPS
DO NOT BUY THIS UPGRADE if your 7", 8", 10" or 12" Meade LX200GPS was
manufactured BEFORE August 2005 - Your scope has plastic gears and needs
the Buck's Gears kit. (Not for 14", 16" or RCX400s)
This upgrade is intended for those 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! About 40% of
the of the improvement associated with Buck's Gears is due to the precision
gears themselves. And the newer scopes that Meade has been shipping with
precision brass transfer gears (in place of plastic gears) have effected this
same improvement. The remaining 60% of the Buck's Gears kit improvement
is what you achieve with Buck's Drive Tune-Up.
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. 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) Eliminate the tendency of the gears to loosen on their axle, due to use of a
larger securing bolt capable of much higher locking torque.
4) - If installed before the scope sees much use - allow 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 consists of detailed step-by-step photo illustrated instructions for 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.
Buck Harley developed the first precision metal transfer gears and worked out
most of the development problems strictly on his own for the good of the
astronomical community. He offered his gear design to PE Corp. with no
compensation to himself simply because of our distribution ability and our
experience with this type of a kit. This Drive Tune-Up kit encompasses the
tune up knowledge that Buck and Peterson Engineering picked up while
developing the gears.
Although the instructions provided are crystal clear, this tune-up is slightly
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.
