Oberdorfer 1001.3 Pump Body – Polyester Replacement Part
A pump body is replaced rather than repaired when the bore has worn oversize, when corrosion has thinned a wall, or when a port thread has been damaged past recovery. The Oberdorfer 1001.3 in glass-filled polyester is the factory casting.
Bore wear is what most often condemns a body. Internals that keep wearing quickly after a rebuild, or a pump that will not hold pressure with new parts fitted, usually means the clearance the new parts are running in is no longer what it should be.
Confirm port size and mounting arrangement against your installation before ordering, as the range covers several port configurations.

Frequently Asked Questions
Q: How do I know the body is worn rather than the internals?
Fit new internals and measure the clearance. If a fresh set still leaves the pump slipping under pressure, the bore is the problem.
Q: Does the body come with any internal parts?
Treat it as a bare casting unless the listing states otherwise, and plan on new seals and soft parts alongside it.
Q: Can a damaged port thread be repaired instead?
Sometimes, with an insert. Whether that is sensible depends on how much metal is left around the port.
Q: Will pipework strain affect it?
Yes. Unsupported pipe hanging off the ports is a common cause of cracked castings and of leaks that return after every repair.
