Description
Overview:
The Cylinder Packing for Hikoki Hitachi engine cutters is a genuine replacement gasket that seals the joint between the cylinder and crankcase. Designed for the CM75EAP and CM75EBP petrol engine cutters, it helps maintain airtight crankcase pressure and correct fuel-air transfer, which are vital for power, smooth running, and long service life. Manufactured from durable gasket-grade material suited to heat, vibration, and petrol/oil exposure, it restores a reliable seal where the original has aged, compressed, or been disturbed during service. As an OEM-matched part (reference 6600397), it fits accurately to the factory profile, supporting correct port alignment and consistent performance. Ideal for routine top-end maintenance and repairs on professional and DIY machines used on site or in the yard.
Key Features:
- Genuine Hikoki/Hitachi part for assured compatibility and reliability (OEM 6600397)
- Forms a secure cylinder-to-crankcase seal to maintain crankcase pressure and compression
- Durable gasket material resists petrol/oil mix, heat, and continuous vibration
- Precise factory profile for a clean fit with no guesswork, reducing rework
- Helps cure air leaks that can cause hard starting, poor idle, or loss of power
- Suitable for scheduled top-end overhauls; replace whenever the cylinder is removed
- Direct replacement for quick turnaround and minimal downtime
- Supports consistent cutting performance in demanding site conditions
Typical Applications:
Used during engine rebuilds or cylinder removal on Hikoki/Hitachi cut-off saws to restore the cylinder base seal.
