The Workhorse Plus tier cylinder head for Komatsu SAA6D107E series engines is engineered specifically for severe-duty applications—such as high-impact rock breaking, heavy dozing, deep demolition, and continuous high-load material handling—where equipment breakdown and job site downtime are completely cost-prohibitive. Assembled using a renewed, pressure-tested OEM core and premium internal components, this top-tier cylinder head features extreme-duty structural upgrades to handle maximum cylinder pressures, intense thermal expansion, and continuous peak-torque demands.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eUpgrades Over the Workhorse Tier: Heavy-Duty Valve Springs\u003c\/h3\u003e\n\u003cp\u003eWhile the Workhorse tier introduces a critical O-ringed deck, the Workhorse Plus upgrades the entire assembly with premium, heavy-duty valve springs and reinforced retainers. This severe-duty valvetrain package prevents valve float and spring fatigue during prolonged full-load operation, easily managing the extreme cylinder pressures and elevated exhaust backpressures common in modern heavy equipment turbocharger, Cooled EGR, and Tier 4 Final emissions configurations. The result is absolute valvetrain stability and precise tracking when your Komatsu machine is working at maximum capacity.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eComponents and Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eRemanufactured Casting:\u003c\/b\u003e Built from a premium OEM core casting that has undergone rigorous diagnostic testing and is machined to like-new industrial specifications.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePrecision O-Rings:\u003c\/b\u003e To combat the severe thermal expansion common in modern high-torque heavy equipment, precision O-rings are machined directly into the deck surface.
