There was way too much end float in the distributor shaft to simply shim, so I've pulled it apart and found thisIt apears to me that the thrust washer that sits between the top of the bush boss and underside of the counterweight carrier plate has disintegrated, leaving the two parts to chew away at each other due to the downward thrust on the shaft caused by the helical gears driving it.

The question in my mind is, can the shaft assembly be salvaged by simply replacing the thrust washer with one or better two of suitable thickness, or will it just chop out again.

A breakdown diagram would be very helpful at this point.

Put the old dist back in at +5 initial and getting +40 total around 3000 and it is running great.

There should be a fibre washer & a steel shim between the dizzy housing & the carrier plate. You would have to check that there is clearance between the advance plate & the shim, so that it doesn't interfere when it advances.

Thanks. Yes, it still clears the bottom of the posts where they recess into the plate. I will see if I can lay my hands on some correct size washers. Pity I seem to have disposed of all my old points dissys to rat from.
