8-94392002-4 Isuzu 4HK1 6HK1 Engine Valve Bridge for Hitachi Sany Excavator
This product is a valve bridge (also known as valve crosshead / valve yoke), with part number 8-94392002-4, designed for Isuzu 4HK1 and 6HK1 series diesel engines. The valve bridge is a critical transmission component in the engine valve train, mounted on top of the valves to transfer driving force from the camshaft or rocker arm to two valves of the same group (intake or exhaust) simultaneously, ensuring synchronized and precise valve opening and closing. Manufactured from high-strength alloy steel via precision forging/casting, followed by heat treatment and precision machining, it offers excellent impact toughness and wear resistance. It is widely used in Hitachi and Sany excavators.
OEM Specification – Manufactured to strict Isuzu OE standards with precise dimensions for direct replacement without any modification.
High-Strength Material – Made of premium alloy steel with excellent impact strength and fatigue resistance to withstand high-frequency alternating loads in the engine.
Precision Machining – Contact surfaces precision-ground for accurate fit with valve stem tips and rocker arms/camshaft, ensuring consistent valve lift.
Wear-Resistant – Surface hardened for superior wear resistance, effectively extending service life.
Cost-Effective – OEM quality at competitive aftermarket pricing.

After installation, manually turn the crankshaft to check valve clearance; adjust according to OEM standards if necessary.
It is recommended to replace all valve bridges on the same engine as a complete set to ensure consistent valve train performance.
Replace immediately if obvious wear, cracks, or deformation are found on the contact surfaces.
