Function of the Oil Seal Kit

The oil seal kit helps:

• Prevent crankcase oil leaks
• Maintain proper lubrication inside the pump
• Separate the oil and water chambers
• Protect bearings and internal components from contamination
• Restore reliable sealing performance
• Extend pressure washer pump service life

Replacing worn oil seals helps maintain proper lubrication while protecting critical internal pump components from premature wear.

Common Signs Replacement Is Needed

Replace the oil seal kit if you notice:

• Oil leaking from the crankcase
• Water contamination in the pump oil
• Visible seal wear or deterioration
• Loss of crankcase lubricant
• Pump rebuild or scheduled preventive maintenance
• Excessive oil consumption

Replacing worn oil seals promptly helps prevent bearing damage and costly internal repairs.

Installation & Service Notes

• Shut down the pressure washer and relieve all system pressure.
• Remove the pump according to the manufacturer's service procedures.
• Drain the crankcase oil before disassembly.
• Carefully remove the existing oil seals.
• Clean all sealing surfaces thoroughly.
• Inspect the crankshaft, bearings, and seal surfaces for wear or damage.
• Install the new OEM oil seals according to the manufacturer's specifications.
• Refill the crankcase with the recommended Comet pump oil.
• Verify proper operation and inspect for oil leaks after startup.

Important: Inspect bearings, water seals, packings, ceramic plungers, and O-rings during service. Replacing related wear components at the same time helps maximize pump reliability and long-term performance.

Maintenance Recommendations

• Inspect oil seals during routine pump maintenance.
• Replace worn seals at the first signs of leakage or oil contamination.
• Maintain the proper crankcase oil level using the manufacturer's recommended lubricant.
• Change pump oil according to Comet's recommended maintenance schedule.
• Use only genuine OEM Comet replacement parts and approved lubricants to maintain optimum pump performance, reliability, and long service life.
