Kit Contents
The General Pump Kit 70 is a comprehensive maintenance kit that includes the OEM internal service components required to rebuild K7 Series unloaders, including seals, O-rings, backup rings, and other internal wear parts needed during routine maintenance. The kit services 16 internal component positions within the K7 unloader assembly.
Why Perform Routine Maintenance?
Over time, internal seals and moving components wear due to:
- Continuous high-pressure operation
- Heat cycling
- Water contamination
- Normal mechanical wear
- Extended bypass operation
Replacing these components helps:
- Restore factory pressure performance
- Improve bypass operation
- Reduce internal leakage
- Protect the pressure washer pump
- Extend equipment lifespan
Common Signs Service Is Needed
Rebuild the K7 unloader if you notice:
- Pressure fluctuations
- Reduced cleaning pressure
- Water leaking from the unloader
- Inconsistent bypass operation
- Difficulty adjusting pressure
- Delayed trigger response
- Visible wear during inspection
Performance Benefits After Maintenance
- Restored pressure regulation
- Improved bypass performance
- Better sealing
- Reduced pressure spikes
- Extended unloader service life
- Improved pump protection
- Lower maintenance costs
- Reliable OEM performance
Installation Notes
- Shut down the pressure washer and relieve all system pressure.
- Remove the K7 unloader from the system.
- Disassemble the valve according to the General Pump service manual.
- Replace all worn internal components using Kit 70.
- Inspect the valve body and piston for damage before reassembly.
- Reinstall the unloader and adjust operating pressure.
- Test pressure regulation and bypass operation before returning the equipment to service.
Important: Use only genuine OEM replacement parts and follow General Pump service procedures to ensure safe operation and maximum performance.
Maintenance Recommendations
- Service the unloader as part of scheduled preventative maintenance.
- Keep inlet water filtration clean to reduce internal wear.
- Avoid prolonged bypass operation whenever possible.
- Inspect seals and internal components during routine service.
