They only tightened up as you pushed the cups in further than their normal operating position. They tightened onto the unworn diameter at the inner edge of the bore. The outer diameter above the circlip will also be unworn.

Can peen them in a bit. Welding over the top can cause all kinds of stress in the joint

cup | triax | difference | needle |
20.4mm (original) | 16.5 | 3.9 | 1.9 ( 1.9 x 2 needles = 3.8mm) |
21.4mm (from junk pile) | 16.5 | 4.9 | 2.4 ( 2.4 x 2 needles = 4.8mm) |
Easy to keep the needles in place! Grease the cup and insert the needles. Use the cross to seat the needles into place by rotating the cup several times on the trunion of the cross. Remove the cup and inspect. If the needles appear to lay over then you need to fit another needle. Do this for all four cups and needles. From memory, there are 25 needles per cup???? Fit one cup and its needles into the cross, but not all the way. Leave clearance in the yoke so that you can slide in the cross and the seal. Using a rotating action, work the cross into the cup. Press the first cup home and fit the circlip. Now press the opposite cup in, keeping it square. Fit the circlip. It should click straight into place. If it won't you have knocked over a needle and all will need re-doing.
Use the same procedure to do cup three and cup four! Be very careful with the alignment when inserting the cross into the third cup.
All I have ever used is a 100mm vice and some carefully selected sockets. Leave the cross fully inserted in the first cup while you press in the second. Helps to align things a bit better. Do you have cork and tin seals or the more modern rubber seals?That's exactly what I tried to do! I think what happend is I pulled the cross out to far as I was pushing the second cap in and displaced some needles. Then didn't get the 2nd cup to sit even enough as it pushed in. Maybe using the press will be safer (I need to fix it first, I broke it the last time I did a CX balljoint). Its almost impossible to tell if any of hte needles have moved.
I wouldn't be suprised if I distorted the yoke trying to get it back apart. Its incredibly hard to dismantle if you can't push evenly due to needles in the base of the cup (infact I'd say impossible).
excellent. They are soft supple rubber seals on all the crosses hereAll I have ever used is a 100mm vice and some carefully selected sockets.

My vice handle is now not straight anymore as I use a piece of one-inch square tube as a leverage extension.
Pity! The old tin cups were better at centralising the cross as it is inserted. I used to cut new rubber-impregnated cork to fit in the tin cups!excellent. They are soft supple rubber seals on all the crosses here
