13050E0130 Camshaft Gear Assy

13050E0130 HINO J05E Camshaft Gear Assy For SK350-9 Kobelco Excavator

Product Overview

The 13050E0130 J05E Camshaft Gear Assembly is the gear mounted on the camshaft that meshes with the engine’s timing gear train. Driven by the crankshaft via the idler gear, it rotates the camshaft at exactly half crankshaft speed, ensuring the engine’s valves open and close in perfect harmony with piston movement. This precise timing is fundamental for proper air intake, combustion, and exhaust .

Manufactured to meet exacting HINO and Kobelco specifications, this gear assembly features precision-cut teeth, correct pitch dimensions, and proper hardness for long-lasting durability. Each gear is engineered to maintain the exact angular relationship between the crankshaft and camshaft, which is critical for optimal engine performance, fuel efficiency, and emissions control .

Key Features & Benefits

• Precision OEM Fit & Timing: A direct replacement for part number 13050E0130, guaranteeing perfect gear alignment, correct tooth engagement, and restoration of factory-specified valve timing for your SK350-9’s J05E engine.

• Eliminates Timing Gear Noise: Replaces worn gear teeth and bearings to eliminate knocking, whining, or grinding noises from the front timing cover area.

• Ensures Critical Engine Synchronization: Maintains the exact angular relationship essential for proper valve operation and fuel injection timing, directly impacting engine power, efficiency, and reliability.

• Prevents Catastrophic Engine Damage: A failed camshaft gear can cause the timing system to jump teeth, leading to bent valves, piston-to-valve contact, and complete engine destruction .

• Durable, Hardened Construction: Made from high-grade alloy steel, precision-cut and heat-treated (case-hardened) for maximum surface hardness and wear resistance, ensuring a long service life under continuous operation .

• Engineered for Low Noise & Vibration: Precision manufacturing minimizes operational noise and vibration, contributing to smoother engine performance and improved operator comfort .

Frequently Asked Questions (FAQ)

Q1: What are the symptoms of a failing camshaft gear (13050E0130)?
A: Common warning signs include:

• Loud, rhythmic knocking or grinding from the front of the engine (timing cover area).

• Engine performance issues: loss of power, rough idle, hard starting, or poor fuel economy due to incorrect valve timing.

• Check Engine Light with diagnostic codes related to camshaft/crankshaft timing correlation.

• Metal debris in the engine oil during oil changes, indicating gear wear.

Q2: Is this gear compatible with my Kobelco SK350-9 excavator?
A: Yes, the 13050E0130 Camshaft Gear Assembly is specifically designed for J05E engines in Kobelco SK350-9 excavators. This engine powers many Kobelco -9 Series models and is known for its robust construction and reliability .

Q3: Does replacing this gear require an engine timing procedure?
A: YES, absolutely. Replacing the camshaft gear is a major engine timing procedure that requires:

• Setting the engine to Top Dead Center (TDC) for cylinder #1.

• Removing the front timing cover.

• Carefully aligning all timing marks on the crankshaft, idler, and camshaft gears.

• This complex task must be performed by a qualified diesel technician using the proper service manual and specialized tools. Incorrect timing can cause severe engine damage.

Q4: Should I replace other timing components at the same time?
A: It is highly recommended. Timing gears wear as a matched set. If the camshaft gear is worn, the crankshaft gear and idler gear(s) it meshes with are also likely worn. Replacing the complete timing gear set ensures proper meshing, quiet operation, and prevents premature wear on the new component.

Q5: Why choose an OEM-spec gear over a generic alternative?
A: The 13050E0130 is engineered with exact tooth geometry, proper heat treatment, and precise balance . A generic gear may have incorrect hardness (leading to rapid wear), imperfect tooth profile (causing noise and stress), or imbalance (creating vibration), any of which can lead to premature failure and severe engine damage. Kobelco genuine parts are manufactured to the same exact standards as when the machine was designed, ensuring perfect fit and durability .
