Webasto – rebuild circulating pumps, or replace?
All,
I’d like to get feedback on the collective wisdom on rebuilding versus replacing the circulating pumps for a Webasto 2010 in our 1997 Country Coach.
The Webasto blower motor died, and during the pulling apart of the system, we noted a leak from one of the two MP (School Bus) circulating pumps that are part of the circuit. {The water circulates for bus interior [floorboard] heat, water heat assist, and engine warming.} The leak may just represent the O-ring needs replacement, but as we are already replacing the blower motor (not repairable), should we consider replacing the two water circulation pumps as well, given they are all the same age?
Replacing the pumps wouldn’t be cheap (~$350 each x 2), considerably more than replacing just O-rings. But, is that a pennwy-wise, pound-foolish approach? $700 vs. $20 is significant, but not compared to sitting on the roadside…
I’m not sure the failure modes for these pumps (i.e., if the O-ring goes, does that suggest the pump bearings or other seals are next?), so looking for experiences and recommended approaches considerations, pro and con.
Thanks!Mike

I just replaced my circa pump , because it was leaking out off the seal , but it is very hard to replace the seal in pump without destroying something else but it can be done , depending on what kind of pump you have , you may be able to rebuild it you would have to find shop that can do that

I bought a couple of those pumps a few years ago from MP Pumps direct and I don’t remember them being anywhere near that much money.
I will try to find my invoice tomorow and post all the info.
If they are priced as I think, I would just replace the whole pump. As soon as you fix the leak one of the electric motors will go out.
Good Luck will post in the morning. You may be right, I did find them at this website for $2400
Part number 29924 12Volt

I found my invoice for the two pumps I bought. Keep in mind this was October of 2010. I called the dealer on the invoice and they would have to call MP Pumps to get a current price.
Call the phone number to corporate office and tell them where you are and they will give you the phone number of the closet dealer.
