How to repair the oil leakage of the high pressure washer?

When there is oil leakage from the high pressure washer, the causes can be diverse, and specific measures need to be taken based on the exact causes. Common methods of handling the issue include replacing the seals, adjusting the amount of oil, or replacing worn-out components. Here are the specific steps involved:

Diagnose the cause of the oil leak.

Aging of seals: Aging of seals is one of the primary causes of oil leakage in the machine head. Seal or gaskets gradually lose their elasticity over time, leading to a decrease in sealing performance.

Inspect the sealing rings or gaskets. If the seal have hardened or become deformed, new seal need to be replaced to ensure the proper sealing performance of the machine head.

Component wear: Components such as piston rods and oil seal may wear out after prolonged use, losing their original sealing properties, which can lead to oil leaks in the machine head. In such cases, it is necessary to replace the damaged components or the entire machine head to ensure the proper functioning of the equipment.

Or the entire machine head assembly.

Excessive oil: When there is too much oil in the machine, it can seep into the oil leakage holes or other openings, leading to oil leakage. In such cases, it is necessary to drain the excess oil to reduce the risk of oil leakage from the head unit.

Repair procedure

Replace the seal: Turn off the power supply, disassemble the area where the oil is leaking, clean up any residue from the old seals, install new seals or gaskets, and apply a specialized lubricant to enhance the sealing properties.

Adjusting the oil level: Check if the oil level exceeds the mark; if it does, use the oil pump or manually expel the excess oil.

Replacement of worn-out components: If the piston rod or oil seal is severely worn out, it is necessary to purchase original factory parts for replacement to prevent secondary oil leakage.

Test run

After the repair and boot-up test, observe if there is still any oil leakage; if necessary, repeat the inspection.

Note

Before commencing any maintenance work, ensure that the machine has been shut down and the power supply has been disconnected to guarantee safety.

Overall, the issue of oil leakage from the wash machine head can be easily resolved through proper maintenance and repair procedures.

Problem. If you are not familiar with the internal structure of the machine, it is recommended not to attempt to repair it yourself, as this could lead to more severe issues. It is advisable to seek the assistance of professional technicians to ensure that the problem is properly addressed.
