4TNE94 / 4D94E Engine Overhaul Gasket Kit for Yanmar, Komatsu, Hyster Forklift

High-Performance Sealing Engineered for Intensive Forklift Duty Cycles

Industrial forklifts operate within enclosed engine bays where cooling efficiency is limited and thermal cycling is severe due to constant load lifting and direction changes. Over time, these conditions degrade the original head gasket and elastomeric seals, leading to hazardous external drops and internal fluid contamination.

Our Premium Aftermarket 4TNE94 / 4D94E Full Gasket Set utilizes premium advanced composite materials and high-grade elastomers. It is uniquely engineered to withstand extreme combustion pressures and corrosive industrial fluids, preventing costly logistics delays and keeping your forklift fleet moving.

Q1: Are the Yanmar 4TNE94 and Komatsu 4D94E gasket kits completely identical and interchangeable?

A: Yes, they are fundamentally interchangeable. The Komatsu 4D94E engine is built on the Yanmar 4TNE94 engine platform architecture. Therefore, the core components such as the cylinder head gasket, valve cover gasket, and main oil seals share identical dimensions. Our kit is compiled to cross-reference both models, guaranteeing a precise fit for either designation in your service manual.

Q2: What causes the cylinder head gasket on a Komatsu 4D94E forklift engine to blow out?

A: Forklifts often operate in dusty environments where radiators can become clogged, leading to minor engine overheating. Because the 4D94E experiences rapid thermal expansion during heavy lifting, an overheated block will warp slightly, crushing standard low-grade gaskets. Our premium gasket kit uses reinforced structural fire rings and high-density cores to resist crushing and maintain a tight seal under elevated thermal conditions.

Q3: Does this kit include both the front and rear crankshaft oil seals?

A: Absolutely. This is a full major overhaul gasket set, meaning it includes all seals from the top cylinder head to the bottom oil pan. Both the high-exposure front crankshaft oil seal and the heavy-duty rear main seal are included, molded from premium elastomeric rubber to prevent oil drops onto your warehouse floor.

Q4: How fast can I get this kit if my forklift is currently down and stopping warehouse operations?

A: We understand that a down forklift disrupts your entire material handling workflow. We prioritize fast logistics by dispatching orders via premium international express carriers like DHL, FedEx, and UPS. Standard global transit takes only 3-7 business days to arrive directly at your maintenance shop. Complete tracking details are emailed immediately upon shipment.
