Hi Walter

This maybe of use to you and perhaps others.

I can't remember exactly where I found it, only that I came across it a few months ago whilst researching different point motors with a built-in aux switch.

One of the common problems found when fitting SEEP point motors to PECO pointwork is trying to get the point motor to fire correctly to both sides with the auxiliary switch working cleanly either side of centre. This is caused by the throw of the PECO point being somewhat less than that of the point motor.

After various ideas have been tried the following appears to be the simplest and best solution:

Before fitting open the mounting holes into slots with a small round file.

Use a pair of small clips or spacers to hold the point blades in their 'mid' position

Fix the point motor underneath the baseboard making sure that the axis of the point motor is correctly aligned with the point tie-bar

Use round-headed screws to make sure that the point potor is firmly held in place while allowing it to be moved along its axis.

Before tightening the point motor ensure that the operating bar is in the centre position between the solenoids.

This method should ensure that the motor operates correctly and that the switch always operates cleanly to the side that is required.

Hope this helps
