Right, had a crack at them.
The big bearing closest to the crank arms was fine, it was the 3 small outboard bearings in a row that were wrecked, seals were worn out. Didn’t help that the small O-ring was fitted in the wrong place from the start. The small O-ring sits in a groove on the axle inset of the 3 small bearings.
Had bother removing one of the small bearings, the tool only tapped out the inner race leaving a lot of hammering with a small flat blade screwdriver to dig out the remaining outer race.
So from crank-arm to axle end it goes.
Large bearing, large seal, small O-ring (on axle groove), 3 small bearings, crush/washer, then the screw to hold it all securely in place
