Primer - HEQ5 Synscan upgrade


Recommended Posts

I recently upgraded my scope with the Syncan upgrade. Purchased from the nice man at FLO

The following is a step by step run though of the installation.

Hopefully someone will find this usefull.

A box arrives :(

Step 1

I suggest laying everything out neatly - the only thing that I needed in addition to the tools supplied was a pair of long nose plyers. The plyers helped in in removing the brass wheel from the RA and DECaxis. Having long nose plyers helped in retreiving the little screws that hold in the motors - they are a little buggers when they slip out of your fingers. Also remember that some of the things that you screw in are delicate (PCB and covers) and do not need to be as tight as you can make them, just tight will do ;) .

Here is the box contents

Step 2

Undo the 6 screws that hold on side panel as shown in this image.

This shows the motors

undo the two screws holding the top (curved) cover on. Then spin the mount round 180 degrees and undo the screws shown in this image.

Step 3

Shown in this image are the items that you have removed laid out nicely - you are going to need these later.

Step 4

You need to remove the motors, First you need to loosen the screws that hold the motors in place - just a little. Then you need to use the allen key to loosen tiny little bolts that hold the brass wheels in place. Once loose you can pull the brass wheels off I had a little trouble with one and had to use the plyers - remember that there are two little bolts per brass wheel and they both need to be loosened.

Once the brass wheels are removed you can then spin the mount over to remove the connectors from the PCB

Finally undo the screws completely that hold the motors in place, gently pull the motors out - remembering that the wires have connectors on the end and pulling hard could damage either the wires or the internal connection.

Step 5

Now you have to remove the PCB. There are two little screws that hold the PCB in place, as shown below.

These screws are needed for the new PCB, do not lose them.

Step 6

Now you need to remove the control panel. There are two little screws underneath. These screws are also required for the new control panel.

You are now at the half way point.

Here is a picture of the bits you have removed that you are going to need again. You'll notice the screws for the first panel you removed are still in the holes on the panel itself. So you have the Curved top panel with screws, L shaped panel with screws, two little bolts from the PCB and two little bolts from the control panel.

Also you should have left over the following peices...

Step 7 add the control panel, poke the wires through the hole and ensure that they come out on the opposite side to where the motors go. Use the two screws that you saved earlier.

Step 8

Add the polar scope, this just pushes in place . You can see the wires from the motors in the correct position.

Step 9

Now add the PCB back in place, using the two screws saved from earlier.

Step 10 add the new brass wheels - they are both the same. Do not tighten them to start with as they need to be adjusted to match the motors later.

Step 11 now install the motors - they will only fit one way. The motors have two differnt size brass wheels, so you cannot get them the wrong way round. But as you look at the picture below the DEC motor has the larger wheel and goes on the left. The RA motor the smaller wheel and goes on the right.

As you offer up the motor to it's new home you need to feed the wire through so that you can get to it from the other side, it's a little fiddly but not hard, this needs to be done for both motors. Once the wires are poking out the other sixe, you can start "screwing" in the allen key bolts. Remember to get all the bolts started before tightening the first. Make sure that the wheels are fully engaged without being over tight.

Step 12 attach all the connectors to the PCB, all the connectors are different sizes except two and therefore will only fit in one position, the PCB is marked for the other two.

Step 13

Add the grease on the gears, spin them round by hand to ensure that they are greased all the way around.

Step 14

Add the curved top cover back in place.

Attach the handset holder to the accessory tray.

Step 16

Plug in the handset.
