Thanks for keeping stuff available murph!Maste's pump is on the way to him. I tore down three today, one of them the housing was bad, the OD fit on the mechanical seal was eroded. ..It had been taken apart and the deficient filled with red RTV....L... that didnt work. My guess is the housing not being serviceable will a rarity.
These are pretty finicky, if you are ham fisted, rebuilding these ain't for ya. Several precision fits that need to work together at the same time during assembly. I will probably sell a complete kit, but there will be no returns and no warranty, on the kits. Pumps I rebuild will carry one.
