Genuine OEM PACCAR 05-16401 Engine Rubber Mount (Kenworth/Peterbilt)

Restore proper engine isolation and vibration damping on your Kenworth or Peterbilt heavy-duty commercial truck with this genuine PACCAR 05-16401 engine rubber mount. Engine mounts isolate engine-generated vibration from the chassis frame — critical for driver comfort, cab NVH reduction, and protection of driveline, cab, and accessory components from vibration fatigue. Worn engine mounts cause increased cab vibration, driveline problems, accessory drive damage, and premature component wear. Genuine PACCAR Genuine Parts™ OEM — sold through the Kenworth and Peterbilt authorized dealer network.

Signs Engine Mount Replacement Needed:

  • Excessive cab vibration during idle or acceleration
  • Visible cracks, tears, or deformation in existing rubber isolator
  • Engine sitting out of position (visible offset from centerline)
  • Driveline vibration or angle changes
  • Accelerated wear of accessory drive components
  • Rattling or clunking noise from engine bay

How It Works:

  • Engine mount installed between engine and chassis frame bracket
  • Rubber isolator absorbs engine-generated vibration and shock
  • Steel mounting hardware transmits engine load to chassis
  • Multiple mounts positioned around engine for balanced support
  • Result: Isolated engine operation with minimal vibration transfer to frame/cab

Buyer Note – Fitment Verification:

  • Engine mounts are truck year, model, and engine specific. Verify direct fitment via Kenworth/Peterbilt dealer parts lookup with your truck VIN before purchase.
  • Engine mount location typically front-driver, front-passenger, or rear-center on PACCAR chassis — verify which position 05-16401 covers for your truck.

Installation Notes:

  • Support engine properly during mount replacement (use appropriate engine hoist or jack)
  • Replace mounts in matched pairs when possible (both sides at once)
  • Torque all mount fasteners to Kenworth/Peterbilt service specification
  • Verify engine alignment after installation
  • Verify driveline angles remain within specification after mount replacement
  • Perform post-installation road test to verify vibration reduction
