Have spent the afternoon giving my rear diff lock actuator the once over, all in all its in good nick, with none of the corrosion issues, to speak of, that I've heard about.
The only issue was the brushes in the motor.
These were worn right down to the point where the copper wire attached to the brushes was almost rubbing on the armature (prob about 10 thou away).
does anybody know how the wire is actually attached to the brushes, or where I can get suitable new ones?
what I then did was to take out some old brushes from an old electric drill, cut & filed them to fit in the holders, and after much cursing, got them in with the springs behind them & the armature back in (fingers like needles recommended!)
at this stage I was hoping that the contact between the spring & brushes would be sufficient as there was now no wire connected directly to the brushes.
Put it all back together with the cogs & what have you lined up (actuator rod at 55mm when retracted) and time to test......bingo, it works!!!!
but do any of you elecktrickery knowledgeable chaps know if the motor will continue to work of with no direct wire to the brushes, and the contact being made through the spring, or should I try & get the proper brushes or another motor.......... Has any one got a reasonable motor kicking about? Not worried about the condition of the rest of the actuator as long as the motor brushes are ok.
