Removal of the Bearings is quite straightforward :
1. Remove wheel and lie it down on blocks of wood to protect the Brake discs from damage.
2. Remove the Bearing seals, and the retaining circlip.
3. Using a suitable pin punch, drive the Bearings out from the opposite side, and collect the central sleeve.
Fitting the new Bearings, according to the Service Manual, requires Triumph Service Tools.
You could probably make your own easily enough. (

).
The tools are a draw bar ( Long bolt ! ) with a "Support Tool" on one side of the wheel,
and an "Insertion Tool" of the correct diameter for the Bearing,
that pulls the Bearing into the hub as the bolt is tightened.
Bearing Insertion Tool : T3880553 ( Large Face to Bearing ) Approx. £24.50
Bearing Support Tool : 3880070 - T0301 ( Large Face to Wheel ) Approx. £17.50
You are also recommended to fit a new Circlip ( T3500402 Approx. £5.50 ), and new Seals.
Even with the cost of these tools, added to the new Bearings and Seals and Circlip,
it still works out at less than half the £200 quoted. !
When fitting the new Bearings, they should be installed with the Marked or Shielded side facing outwards.
Lubricate the "Knife Edge" of the Seals with Grease to NLGI 2 specification.
Cheers
