65ssimp,
if you can get the waterpump apart ,,without busting the housing,,most bearing places can get the ceramic seals for most any water pump,,with deminsions from vernier calipers. All of the old school bearing warehouses have folded up around were I live due to all the factories folding up.May be same way were you are?
Question. Did they ol boy,,say he DID shut the unit down without getting motor hot,,,when pump was in the leaking stage?
Just a month ago,,our loyal rural road commisioner here was tanked up,,trying to push over tree stumps with an almost new CAT backhoe,,,knocked the oil filter off driving over a tree stump....run the thing till all oil pumped out of the tractor,,and trashed a brand new tractor,,motor..
usually the cowboys that run these pieces dont use a whole lot of finess.
That is a very cool little unit,,that you'll find many excuses to use it,,on,,
take Care,
BC
