I decided to fit the needle roller conversion and have had some fun & games. Mine came from All Balls, and had different length pairs of bearings. I didn't notice this until too late ..... The only way I know of to remove them is destructively, and I couldn't have done it at all without the Dremel I recently bought, to grind through the cages and collapse the bloody things out.
So, and all you proper engineers will quite rightly be nodding sagely at this, it's VERY IMPORTANT to measure carefully before wading in. I bought another All Balls kit, and this one had same-length bearings. What the swinging arm doesn't have though is same-depth drillings for each side, so one side is too shallow for the bearings to fit and I've had to source some shorter ones (22YM2816), ironically the same as the different ones in the first kit I bought!
Measure, measure, and measure again. Including how far you've pulled the inner race in, so there's room for the outer race plus the collar.
We live and learn. Steering head next. I will be VERY careful
