C-E70 E70B Boom Seal Kit - Quick Start Guide
Working Principle
This kit utilizes multi-layered seal synergy. Piston and piston rod seals (NBR+PTFE) form pressure barriers to prevent hydraulic oil leakage; O-rings fill gaps to enhance sealing; dust seals block contaminants and protect the hydraulic system.
Key Installation Steps
- Prepare tools, shut down excavator, and release hydraulic pressure
- Disassemble boom cylinder, remove old seal, and thoroughly clean components
- LubriCe new seal with hydraulic oil and install in correct orientation
- Reassemble cylinder and test boom operation for leaks
Precautions
- Avoid using metal tools to prevent scratching seals
- Follow torque specifiCions when tightening bolts
- Ensure sealing lip faces direction of oil pressure
- Perform no-load test before heavy-duty operation
- Check seals every 500 working hours
