(TS) COMPUTATOR CT-1000 Repair, Service & Upgrade.

...........................................

This Rotator was sent to me for service & repair etc, a interesting design in the fact that the motor is laying on it's side (like worm drive rotators) but all the gearing are on there edge (vertical) with a bevel final drive gear at the top driving the top housing + twin brake wedges activated by solenoid which locks into the top housing as well.

Full stripped down to the last nut bolt & removed a ton of excess grease. Bearing will have to be replaced.

When I finally got rid of all the grease I found a broken guide post for the wedge & a POT not working

Repair broken brake wedge guide post (drilled & tapped). Replace broken POT with a standard 500 ohm Kenpro POT & mod POT drive gears(as the replacement POT has a standard length shaft), the two drive gears have been shortened & shimmed to allow the POT gear to fit on (POT gear was re-drilled & tapped for 2 new grub screws). POT mounting hole had to be lengthened & the location pin hole  was drilled out to give some adjustment, because the a gear was hitting the shaft of the POT (this includes the original POT).

Upgrades:- Moved motor capacitor from the controller to the rotator saving 2 wires. Replaced 10 pin plug/socket on rotator with 7 pin IP67 socket/plug & had the inside edge of the socket hole milled to fit the new socket, This mod means you don't have to unsolder wires from socket to remove the motor/gear box assembly for servicing, bench tests etc, just unscrew the outer nut. Also upgraded the controller 10 pin socket/plug & replaced them with a 8 pin Cinch plug/socket & laser cut & etched mirror stainless steel cover plate. Rewired both units, reassembled, aligned & calibrated. (TS)

(BF) NEW WINCH-UP TOP LAY-OVER TOWER - Supplied rotator set & 3 all  stainless steel side mount brackets.

..............................................................................................................

Supplied a rebuilt, upgraded Emotator 105TSX rotator set & three new all stainless steel side mounting brackets (1 x SMB65ssR & 2 x SMB64 ssB prototype bearing mounts). Using two mast bearing mounts on side mount brackets (SMB64ssB) means he can remove the rotator for servicing etc without disassembling the antenna system. Plus using two bearing means there is no side or vertical loading onto the rotator at all, this gives maximum protection to the rotator & a longer working life.
