Overview – General Parts INSULATOR 4654664 Series
Built to Hitachi specifications, the INSULATOR 4654664 serves Hitachi structural and cab mountings as the insulator; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
An elastomer insulator that isolates a component or mount from vibration and shock. It absorbs the road and working vibration that would otherwise transmit into the structure and the operator environment, so a sound insulator keeps the machine quiet and the mount uncracked.
Applicable Models & Applications
Fitted to Hitachi mounting positions of this shape. Match the insulator profile and durometer against your old part – insulators that look alike differ in stiffness and load rating.
Maintenance & Replacement
Inspect insulators for cracking, splitting and permanent compression set at every structural service. A hardened or split insulator transmits vibration and the cracks walk into the mount.
Replace insulators as a set where they work in pairs. A new insulator against a collapsed one loads the new one unevenly and repeats the failure on the other side.
Confirm the isolating path is intact after fitting. An insulator fitted metal-to-metal insulates nothing and the vibration it was there to stop passes straight through.
Keep common insulators for your model on hand. They are inexpensive, they perish with age, and they are exactly the part missing when a mount needs isolating today.
Price Reference (USD)
The INSULATOR 4654664 generally falls in the USD 5-25 bracket, with expedited freight quoted separately.
Value & Service
We supply brand-new insulators with the profile and rating confirmed against your Hitachi model, so vibration stays isolated.
