After dismantling the cossie and escort dizzys you keep the ERST housing, cossie shaft, phase sensor, and the ERST washers.
We figured 16+mm had to be lost in the top half of the cossie shaft to fit under the ERST cap. It might have been more possibly nearer to 20mm.
So we put the shaft into a lathe and turned the coller under the phase trigger down, leaving a coller for it to seperate the washer from the trigger. This could have been 1mm less but the lathe was old and tools shite. (no CNC for this project!)
we then machined 6+mm off the rotor mount, recutting the slot and sanded the base of the rotor down for it to sit lower on the shaft.
The bottom of the shaft was cut off for the ERST drive plate to sit up onto.
Next we have to make a 4mm thick plate for the phase sensor to sit on. Counter sunk holes will be drilled into it to allow fitting to the ERST housing. Tapped holes into the plate for the phase sensor to be fitted onto.
It looked a mare but was quite simple when we got into it!
Completed photos next week with some luck.
Modified shaft.
Shortened rotor. Should make future servicing interesting!!
