ISUZU Front Engine Mounting OEM Standard Size Direct Fit Verified with Rubber

ISUZU Front Engine Mounting 1-53215172-0 1532151720 for ISUZU LT133 FVR FSR FTR with 6HH1 6HE1 6HK1 6HF1 Diesel Engine Truck — OEM Standard Size Front Engine Mount Insulator Direct Fit Verified

The Front Engine Mounting with OEM numbers 1-53215172-0 / 1532151720 is a verified direct-fit replacement for ISUZU LT133, LT132, FVR, FSR, and FTR trucks equipped with 6HH1, 6HE1, 6HK1, and 6HF1 diesel engines. This engine mounting insulator is a critical vibration-damping component of the engine suspension system, located at the front left/right side of the engine compartment, supporting engine weight, isolating engine vibration and noise, ensuring stable powertrain operation, and improving driving comfort.

The engine mounting insulator is continuously subjected to engine vibration, torque reaction forces, and high-temperature environments. When the rubber ages, cracks, or the metal components corrode, it leads to increased vibration transmission, abnormal engine displacement, and potential drivetrain misalignment. Timely replacement restores proper engine suspension system operation.

When the engine mounting insulator exhibits the following conditions, timely inspection and replacement are required:

1. Significantly increased idle vibration: Aged and hardened rubber, degraded damping performance, noticeable vibration in steering wheel, seats, and dashboard at idle.
2. Increased impact during start-up or gear shifting: Inability to effectively absorb engine torque reaction forces, causing body "jerk" or "impact" sensation during start-up, acceleration, or gear shifting.
3. Cracked or detached engine mount rubber: Rubber separating from metal frame, cracks, fractures, or deformation in the mount body, losing support and damping function.
4. Engine compartment abnormal noise: Loose mount or metal component collision, producing "thumping" or metal impact sounds from the engine compartment over bumps or during hard acceleration.
5. Engine position displacement: Mount collapse or damage causing overall engine position shift, potentially causing fan-to-radiator interference, exhaust-to-body contact, and other cascading issues.

Certification: Manufacturer holds ISO/TS16949 automotive quality management system certification. Supplier declares 100% factory testing on every unit.

Installation Guidelines (Reference workshop manual):

1. Safety preparation: Disconnect negative battery terminal. Support engine weight from below using jack or engine hoist, ensuring engine weight is borne by support equipment.
2. Remove old mount: Remove mount-to-engine-bracket and mount-to-frame bolts, extract old mount. Note bolt locations and quantity.
3. Inspect related components: Check engine bracket, frame mounting holes, and related mounts for wear; replace if necessary.
4. Install new mount: Position new mount, hand-thread all bolts first, confirm alignment, then tighten to specified torque. Reference torque values: 6HH1 engine related fastener torque specifications are 98 N·m (step 1) + 132 N·m (step 2) + 30–60° angle method, specific values per ISUZU LT133/6HH1 workshop manual.
5. Check installation status: Confirm mount is securely installed, no interference between engine and surrounding components (fan, radiator, exhaust, etc.).
6. Road test: Start engine, check idle vibration improvement, perform short road test to confirm no abnormalities.

Maintenance Schedule:

• Every 20,000 km or 6 months: Check mount rubber for aging or cracking, and bolt tightness.
• Every 50,000 km: Check mount damping performance; replace when vibration increases or rubber cracks.
• When significantly increased idle vibration or start-up impact is detected: Inspect mount condition promptly to prevent cascading damage.
