Product Details

Product Overview

Our HD-2349 Engine Cushion Mount is a premium-grade vibration dampening component engineered for severe-duty applications in excavators, bulldozers, and heavy industrial machinery. Designed to isolate engine vibrations from the chassis, this mount ensures operational stability, reduces noise, and prolongs the lifespan of surrounding engine components. We ship globally, with a strong distribution network serving North America, Europe, Asia-Pacific, the Middle East, and South America.

FAQ

Q1: Will the HD-2349 engine cushion fit my Komatsu PC200-8 excavator?

A: Yes, the HD-2349 is a direct replacement for the original Komatsu part numbers 20Y-54-11140 and 20Y-54-11141 used on PC200-7 and PC200-8 models. We recommend verifying your existing mount’s dimensions (height 75mm, bolt M12) against our spec sheet for absolute confirmation.

Q2: What is the recommended installation torque for the mounting bolts?

A: For optimal performance and to prevent rubber compression damage, tighten the center bolt to 85–95 Nm (63–70 ft-lb). Do not exceed 100 Nm. Always use a thread locker (Loctite 242) on the bolt to prevent loosening due to vibration.

Q3: How often should engine cushions be inspected or replaced?

A: We recommend inspecting engine mounts every 1,000 operating hours or annually, whichever comes first. Signs of wear include visible cracks in the rubber, separation from the metal core, or excessive engine vibration felt in the cab. Replacement is typically required every 5,000–8,000 hours depending on operating conditions (e.g., dusty or high-vibration environments).
