FAQ
Q: How can a technician distinguish between the left and right rotor groups when rebuilding a K5V160 pump?
A: The difference lies in the kidney-shaped port layout on the valve plate, which is mirrored for clockwise and counterclockwise rotation. Part number 340702 is configured specifically for the right-side pump section.
Q: What are the consequences of ignoring minor scoring on the face of a bimetal cylinder block?
A: Minor scoring allows high-pressure oil to bypass the sealing face, creating a path that erodes the metal, lowers system pressure, increases oil temperatures, and eventually causes total pump failure.
Q: Does this rotor group come with the internal pistons and shoes, or is it limited to the block and plate?
A: This SKU includes the precision bimetal cylinder block and matching right-hand valve plate. We also supply matching piston sets, shoe retainer plates, and ball guides to provide everything needed for a full overhaul.
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
