Description
ISUZU Engine Mount 8-94334159-0 8943341590 for TFR54 TFR55 4JA1 — OEM Standard Left-Hand Mount
Product Overview

The ISUZU Engine Mount with OEM numbers 8-94334159-0 / 8943341590 is a precision-engineered replacement designed for ISUZU TFR54 and TFR55 series pickup trucks, compatible with 4JA1 diesel engines. This component elastically connects the engine to the frame, effectively attenuating vibrations generated by engine operation and road excitation, preventing vibration transmission to the cabin, improving ride comfort, and protecting the powertrain and surrounding components.

Numbering Note: This product number 8-94334159-0 / 8943341590 is the Left-Hand (LH) engine mount. The right-hand counterpart is 8-94334158-0 / 8943341580. Alternative reference numbers include 94334159, 94428660, 94434207, 94482408.
Working Principle

The engine mount consists of a high-elasticity rubber body bonded to a metal frame through a vulcanization process, installed between the engine and the frame (or subframe). Its core functions include:

  • Vibration Isolation: Utilizes the elasticity and damping properties of rubber to absorb and attenuate vibrations generated by engine operation
  • Displacement Limitation: The metal frame limits excessive rubber deformation under heavy loads, ensuring stable engine positioning
  • Noise Suppression: Effectively blocks the transmission path of engine structure-borne noise into the cabin
Failure Symptoms

Inspect immediately if any of these symptoms occur:

Symptom Probable Cause
Noticeable increased vibration in cabin at idle or driving; steering wheel/seat shaking Aged/cracked rubber; loss of damping function
"Clunking" metallic noise from chassis during startup, gear changes, or over bumps Rubber separated from metal frame; metal-to-metal contact
Engine visibly rocks when blipping the throttle in neutral Ruptured rubber body or severe aging
Visual inspection shows rubber cracking, deformation, or断裂 Natural rubber aging or prolonged overloading
Noticeable shock when shifting to D or R Failed engine mount causing abnormal powertrain movement

Important Fitment Warnings
  • Number Confirmation: This product number is 8-94334159-0 / 8943341590 — the Left-Hand (LH) engine mount. The right-hand counterpart is 8-94334158-0 / 8943341580. Confirm which side needs replacement before ordering.
  • Alternative Reference Numbers: This product can also be referenced by 94334159, 94428660, 94434207, 94482408.
  • Pair Replacement Recommended: Engine mounts should be replaced in pairs (left and right) to ensure balanced engine support and consistent vibration damping.
  • Installation Torque: Refer to ISUZU factory workshop manual for mounting bolt torque specifiions. Final torque must be applied after the engine weight is fully settled onto the mounts.
  • Associated Components: When replacing the engine mount, inspect transmission mount and exhaust hangers — replace if necessary.
  • Professional Installation: Engine mounts are critical powertrain support components — professional installation is recommended.

Installation & Maintenance
IMPORTANT SAFETY NOTICE: Engine mounts are critical powertrain support components that directly affect engine positioning and driving safety. Professional installation is recommended. Engine support is required during installation — improper operation may cause injury or component damage.

Installation Guidelines:

  • Confirm installation position (Left-Hand) and part number (8-94334159-0)
  • Prepare tools: Socket wrench, torque wrench, jack + wood block (for engine support)
  • Recommended to prepare right-hand engine mount for pair replacement
  • Clean mounting surface thoroughly before installation
  • Pre-tighten bolts but do not fully torque until engine weight is settled
  • Refer to ISUZU factory workshop manual for specific torque specifiions

Maintenance Schedule:

Item Interval Notes
Mount visual inspection Every 10,000 km / each service Check for rubber cracking, deformation, aging
Mount function check Every 20,000 km Check for abnormal engine movement
Mount replacement Upon symptom occurrence or 5–7 years Replace in pairs (left and right)
