VH13471E0161 J08E PULLEY, CRANKSHAFT Kobelco SK330-8 SK350-8 Excavator
Product Overview
The VH13471E0161 J08E Crankshaft Pulley is a multi-function component that serves as the primary drive point for all engine accessories via the serpentine or V-belts. More importantly, it is a tuned harmonic balancer, designed with an outer inertia ring bonded to the inner hub via a rubber element. This design absorbs and dampens the inherent torsional vibrations produced by the crankshaft during engine operation, preventing these damaging vibrations from being transmitted throughout the engine. Our replacement pulley is manufactured to exact OEM specifications for weight, balance, and dimensions, ensuring it performs both its driving and damping functions flawlessly.
Key Features & Benefits
-
Precision OEM Fit & Balance: A direct, bolt-on replacement for part number VH13471E0161, guaranteeing perfect fit on the crankshaft snout, correct keyway alignment, and restoration of the engine’s factory harmonic balance.
-
Protects Against Destructive Vibration: The integrated harmonic damper absorbs torsional crankshaft vibrations, preventing excessive stress on the crankshaft, main bearings, and timing gear train, which can lead to premature failure.
-
Ensures Reliable Accessory Drive: Provides a stable, true-running surface for the drive belts that power the alternator, hydraulic pump, water pump, and air conditioner, preventing belt slip, squeal, and premature wear.
-
Durable Construction for High-Stress Duty: Built with a high-strength steel or iron hub and a robust, wear-resistant outer pulley ring, designed to withstand continuous high-RPM operation and belt tension.
-
Prevents Costly Secondary Damage: A failing balancer (where the rubber bond degrades) can cause severe engine imbalance, leading to broken crankshafts or damaged main bearings—repairs that far exceed the cost of timely pulley replacement.
-
Solves Vibration and Belt Alignment Issues: Correctly replaces a unit that may be causing unusual engine shaking, wobbling belts, or repeated belt failures.

Frequently Asked Questions (FAQ)
Q1: What are the symptoms of a failing crankshaft pulley/harmonic balancer (VH13471E0161)?
A: Warning signs include:
-
Visible wobble or run-out of the pulley when the engine is idling.
-
Unusual engine vibration that increases with RPM.
-
Squealing or chirping belt noises that persist after belt replacement and tensioning.
-
Visible separation between the inner hub and outer ring of the balancer, or chunks of rubber missing from the bonding layer.
-
Misaligned or repeatedly failing drive belts.
Q2: Is this just a pulley, or is it a balanced harmonic damper?
A: The VH13471E0161 is a harmonic balancer with an integrated pulley. It is a dynamically balanced, tuned component. A simple “pulley” without the damping function cannot be used as a replacement, as it will not control crankshaft torsional vibration.
Q3: Can I install this myself?
A: Replacement is technically demanding and requires special tools. It involves:
1. Removing the accessory drive belts.
2. Using a high-quality puller designed for harmonic balancers (NOT a gear puller) to remove the old pulley.
3. Cleaning the crankshaft snout and keyway.
4. Installing the new VH13471E0161 pulley using the correct installation tool to press it on without damaging the crankshaft or bearings.
5. Torquing the center bolt to a very high, specific specification.
This job is recommended for professional mechanics.
Q4: Why does the pulley need to be installed with a special tool?
A: Hammering it on or using an incorrect installer can damage the crankshaft’s thrust bearings or cause micro-fractures in the crankshaft. The proper tool applies even, controlled pressure to seat the balancer fully and correctly onto the crankshaft taper and woodruff key.
Q5: Is this a genuine OEM part?
A: This is a high-quality, OEM-compatible replacement balancer manufactured to the exact specifications, including balance and damping characteristics, of the original VH13471E0161 part.
