Product Overview — Part 330-016-98
The 330-016-98 is a precision-manufactured Engine Cushion / Rubber Mount component for demanding industrial and heavy equipment applications. Universal engine mounting cushion block for construction machinery, generator sets, and marine engine applications. Standardized interface for broad compatibility.
The 330-016-98 cushion block follows a standard sandwich-mount geometry that provides straightforward vertical load support with controlled lateral stability. The design is widely used in equipment where the engine does not require precision centred isolation and the primary goal is preventing metal-to-metal contact and reducing structure-borne noise. Standard compounds available in 40, 55 and 65 Shore A to match light, medium and heavy engine installations.

- EN 45545-2 Option: Halogen-free flame retardant meeting smoke toxicity requirements for railway-grade applications
All production batches manufactured under ISO 9001:2015 QMS with full material traceability from raw compound to finished product. Certificates of conformance and material test reports supplied on request.
Installation & Maintenance
- Verify on arrival: Confirm part number 330-016-98. Inspect for transit damage or surface defects — reject any non-conforming item.
- Prepare mating surfaces: Remove all rust, old rubber residue, grease, and loose paint. Flatness tolerance within 0.5 mm for proper seating.
- Correct orientation: Follow the assembly drawing or OEM workshop manual. Incorrect orientation causes premature failure and may void warranty.
- Torque fasteners: Use a calibrated torque wrench with a cross-pattern tightening sequence to the OEM-specified value.
- Post-installation check: Inspect for correct seating and gap clearance. Run equipment at idle to confirm absence of abnormal noise or vibration.
Recommended replacement interval: 3,000–5,000 operating hours or at first sign of cracking, permanent deformation exceeding 3 mm, or detachment of rubber from metal insert.
