Hydraulic pump: rebuild or replace, which pays off?

The main pump loses pressure; teardown shows wear on the valve plate and pistons.
Overhaul is quoted at USD 8,000 with six months warranty; a new pump is 22,000 with a year.
The machine should run four more years. Which is better?

Check the housing and cylinder block; a rebuild that only changes pistons usually lasts half as long.

Over four years, two overhauls approach the price of a new pump, plus downtime.

Repair first and monitor pressure and oil temperature; if it drops again within six months, replace.
