the seals and rear bearing were available locally they are standard sizes. 
The front bearing is the impeller shaft housing , it needed a light hone as previous work had damaged it. 
assemble the armature into the forward pump housing. assemble the rear motor housing onto the field case (brushes out)  then place that over the armature and secure with two screws.

Hi,

You say "seals and rear bearing were available locally they are standard sizes" it would be very helpful if you could tell us the supplier and if possible;e any part numbers. Also did you get new brushes?

I have mine in bits the seals don't look bad very small amount of leakage, It would be nice the get replacements before I extract them. I have New Pump liner & Impeller blades.

Just realised front Oil seal may be different part, not got it out yet, was hopeing not to pull them untill replacements arrive but front seal may be different (422 & 423 of 2350-T-251-711) so, Stuart if you do know the part No it would be appreciated.
