Hi All
I have play in the rear end so does anybody have the bearing sizes for the swing arm area on a WK400 , I have dismantled the rear suspension arm to have a look and whilst the seals give the information
TC 10 24 5
TC 18 26 5
TC 18 24 5

this only relates to the seal sizes plus I would also like to replace the swing arm bearings

Any help much appreciated.

OK as Im at home and cant go out riding I ended up taking it apart, measuring and ordering the following [which does not include the swing arm.]
https://www.bearingboys.co.uk/
1 of needle bearing 18 internal 24 external and 16 wide [ imprint on original NK182416]





2 off needle bearing 16 internal 24 external 20 wide - should be 22 wide but they didnt have any and I can see it making much difference
[ imprint on original NA6901]





2 off needle bearing 18 internal 26 external 20 wide [ imprint on original NK18/20]




the casting looks a tad worn though as there's a ridge worn by the bearing on one side of both ends, I`ll fill the ridge off and see how it fits
