Hi Bill,
Can another brand name pump like General or AR or Cat pump replace the Karcher 4000 axial cam pump?
If yes, is it just to take out and change or do you have to modify?
Thanks in Advance,
Melvin.
Answer
Unfortunately you could not purchase this machine with another brand of pump, meaning the machine could not be customized from the factory. However, you could definitely purchase a General Pump, CAT PUMP, or AR brand pump and install it on this machine with no modifications needed. You would just have to make sure that the replacement pump you purchased accepted a 1" diameter shaft and was designed for a horizontal installation.
