Laplant Choate Hyd. Pump??

Mike in Gardenerville NV is the expert on that pump. It is a 5 piece seal but if you took it apart and mesured the hole where the seal seat is and shaft size I'm sure any good bearing house could get you new style seal for it, thats what we do for the old waterpumps with old type seal. I have a book on it if you need info.

Thanks Willie, Does Mike post here often, how could I get in touch with him??For now i'm going to try to shim up the spring a bit to give it a little more presure on the seat. Thanks again,quinq

I have had good luck replacing the malt able piece spring loaded seals in older low pressure hydraulic pumps with modern lip seals.Have a hydreco I am going to do this to on a D6 9u with a cat bulldozer blade.

Ray54, I assume meas. OD&ID and order seal ?? Seems to me that an ordinary lip seal wouldn't withstand pump housing pressure. Is there some special type I should be looking for??
