I've been fighting with my scanner for the past week, and have finally
coaxed it into doing what it's supposed to do.  Consequently I'm trying to
get caught up with all the scans that need to be done to bring the
Attachments section of the LML homepage up to date.  I've started getting
the factory Service Bulletins scanned in, and have just posted copies of a
few faxes I received from Doug Weeldryer regarding the LC20 hydraulic pumps
and some notes from Jefco about ratios.  (These faxes were originally sent
to me by Angier Ames, as verifications of telcons between Doug and
himself.)  You can get directly to the Attachments area by following this URL:

While I'm on the subject of the LC20 hydraulic wiring, there was a question
here not long ago about the position of the gear switch and its
relationship to the terminals on its backside... someone mentioned that
they thought the lower 2 terminals should be connected to the low pressure
relay (gear down) and the upper terminals to the high pressure one (gear
up).  I checked the switch which came with my kit and found that if it's
wired as per the drawings (figure 14-17 or 14-17a), it will work as
intended.  As I suspected and mentioned previously, the switch end of the
bat handle sort of points to the two terminals that are closed, so with the
handle in the [gear] down position, the upper terminals are made.  With the
switch in the [gear] up position, the lower termials are made.  Once again,
be sure to check for continuity before final wiring, just to verify that
the switch is going to do what you expect it to.
