taken from another post:
I have found the receipt for the Hybrid Pump bearings.
Not sure if the part numbers would make sense, so I have measured the bearings with vernier callipers so the correct parts can be ordered.
I bought mine from Brammer UK Ltd, in Hereford (01432 276630). The part numbers are 61900-2Z and 608-2Z. They were in stock at the time.
The dimensions for the front bearing are 22mm OD, 10mm ID, 6mm width.
The dimensions for the rear bearing are 22mm OD, 8mm ID, 7mm width.
