Few of these available on auction sites - new bearings and seals and about 5% the cost of a new pump. My pump has developed a steady drip from the weep hole under the pump indicating that the seal has gone - done 90K miles in 17 years so not too bad and clearly needs sorting. Any one tried to repair the pump - not obvious how to take it apart - presume heat impeller and see if it can be pulled off and then press out seals and bearings. Could be beyond my limited workshop facilities so will probably buy a new one, but curious to know if anyone has had a go!
