Waterpump overhaul: realistic?
Some 8000 km ago, i did a cambelt and waterpump change including all rollers and bearings etc. To have peace of mind, I'm now installing a Porkensioner and a new belt. But when checking the play on all bearings, the waterpump had about 2 mm of play and made a lot of noisewhile turning. Clearly the bearing is totally gone. Probablydue to the fact that the seal is only a few years old, it didn't leak.
Since the WP is quite expensive, I was wondering whether it's possible to take it apart and only change the bearing. Has anybody done it? If so, how? It's a WP with a metal blade, not the plastic one.
The car is a '85 Euro S 16v

I understand that quickest and easiest is to replace it for a new one. However I'm fed up with constantly buying new parts to replace old parts that are still 80% okay. I'd rather only replace the 20% that's broken...

The cost of a new Laso pump (with the new plastic impeller) is worth the cost of protecting your engine. Plus its not much money at all $295.

I'm going to guess that the pump originally put on was a "rebuilt" pump.

Save a few bucks to risk a couple of thousand. False economy is not a good deal. Get a new pump from Roger, he has the one's with the nice plastic impeller.
OTOH, if 300 is too much consider the car you are working with. A 20+ year old car is going to need quite a few expensive parts replaced. Rebuilding isn't always the smartest option. (Honda Civic water pumps cost 80 bucks).

I agree with SeanR: probably most of the WP's we buy have been rebuild. Why would you otherwise get a refund when you ship the old one back!?!
Anyway, if the new improved WP has a plastic impeller, I guess it's wise to buy a new one anyway...
So what's best? A metal impeller or a plastic one? I'm not asking for what's easiest obtainable.

I heard the plastic impeller was best because if the bearing play was out of spec, the plastic impeller wouldn't "chew" up the block like a metal one would.
