BETA EVO Head bearing replacement

[smallboy]

Hi all

Just stripped my front steering,to find the bottom bearing being very notchy,should there be a seal at the top,as the bottom bearing is very rusty?how do you remove bottom bearing from the bottom yoke?

Cheers

No, there shouldn't be a seal in the top, but if you put some silicone seal round the steel cap to reduce the gap.

To get the bearing off, break aprt the bearing until only the inner race is left, then using a slitting wheel (i use a little dremel one) cut a slit in the bearing as deep as you can then hit the slit with a chisel causing the bearing to crack, before i get told other methods, you can alternatively use a bearing puller to get it off or try heating it up.

To put the new bearing on, either find a tube that fits on the inner race and tap it back to the bottom or as i did stick the bearing in the oven for a little while and it will just drop on and shrink into place as it cools, 1 other thing, try not to blast the headstock with the jetwash or any bearings, it just pushes the grease out and water and grit in.

i fitted a greese nipple to mine when i had it in bits,

then when you have finished washing it just a quick squeeze

with a greese gun and bingo
