Points not throwing completely (partial range of motion using EPL drive)

As some of you may be aware. The track has been down for several months but the points haven't been wired up until now. This is affecting 2 points - an Trainline R3 (similar to LGB's R3) and Piko's curved point. I'm using LGB 12010for the motors.

Troubleshooting I've done so far:
  • Added LGB's maintence oil to the pivot point and the end of the blades - no improvement
  • Tried an alternative switch drive - no improvement/same issue
  • Tried the switch drives without a load (disconnected from the points - I get the full range of motion with the loud "thunk"
  • Tried the official LGB (Orange/White) wire (as opposed to the one I was using) - no improvement
  • Tried a different power source/control. I was using my DCC system and controlling them from my switch decoder. I tried an LGB transformer and LGB momentary siwtches - no improvement

Given what I've tried above I suspect it is a mechanical issue and not electrical (although I'm happy to be corrected on this). For whatever reason, there is too much resistance from the blades for the switch drive to complete the motion.

Has anyone experienced this before or does anyone have thoughts on how to address this?

(note - I also posted this in the Garden Railways Facebook group in case any of you think you're seeing double)
 
The usual reason for this is that the point motor is not centred correctly. Easy test is to see how much slack is on the throw bar on each position. Cure is to take the top of, centre the armature, centre the throw bar & carefully put it back together. It happens for no reason.
