I didn't know what sort of shape the bearings in the spindle motor of my VHF3 were in, so I opened the motor up to have a look, then replaced the bearings since they're cheap. The service manual seems a bit brief, so here's my take.
Bearings are Swedish SKF 6206-2Z and 6205-2Z-C2. Not sure why the C2 is there, but I replaced it with the same.
If you take your motor apart then mark the three parts so they go back together the same way. You can figure it out afterwards, but it's easier to just mark them first (I marked them but cleverly cleaned the marks off before reassembly).
I typed the number off the belt - 1165L1 - into Google, first hit was RockAuto, which had exactly 3 (the quantity needed) on closeout for $1.38 each.

This is how the motor wires attach to the terminal block.

This is the belt adjustment on the other end of the motor, which is less obvious.
