The Rocker Arm (OEM Numbers: 13902-E0010 / 13902E0010) is a premium-quality, direct replacement valvetrain component designed for Hino J08C and J05E diesel engines, commonly used in Hino medium-duty trucks.

Function: Transfers motion from the camshaft or pushrod to the valve stem, opening and closing the engine valves. Ensures precise valve timing and efficient combustion for Hino J08C/J05E diesel engines.

• OE Quality: Manufactured to Hino dimensional and material specifications for perfect fit and reliable valve actuation
• Hardened Contact Pad: Wear-resistant surface reduces friction and extends service life
• Precision Pivot Bore: Smooth operation on the rocker shaft
• Durable Construction: Forged steel/ductile iron withstands high cyclic loads
• Restores Valvetrain Performance: Eliminates tapping noise, uneven valve lift, and power loss
• Direct Replacement: Matches OE dimensions - simple installation
• Cost-Effective: Affordable alternative to genuine Hino rocker arms

This rocker arm is designed for Hino J08C and J05E engines.

• Hino 500 Series (light/medium trucks)
• Hino Ranger (medium trucks)
• Hino Dutro (select models with J05E)

Installation steps (overview):

1. Remove valve cover and any related components
2. Remove the rocker shaft assembly or individual rocker arm (depending on design)
3. Inspect the rocker shaft and pushrod/camshaft for wear
4. Lubricate the new rocker arm's pivot bore and pad with engine assembly lube
5. Install the new rocker arm onto the shaft or pedestal. Ensure proper orientation
6. Torque the rocker arm shaft bolts or adjustment nut to specification
7. Adjust valve lash to OE specification (typically 0.25-0.35mm cold for Hino J-series)
8. Install new valve cover gasket and reassemble
9. Start engine and check for abnormal noise
10. Re-check valve lash after warm-up if required
