JOHN DEERE MINI EXCAVATORS:
• John Deere 50D/60D 4TNV94/98 2.8-3.3L Diesel (2006-2014)

IMPORTANT:
This is an INTAKE MANIFOLD gasket for the Yanmar 4TNV94/4TNV98 engines. Do NOT confuse with exhaust manifold gaskets or valve cover gaskets — completely different parts. Found in John Deere 50D/60D compact excavators and Takeuchi TB250/TB260 excavators. The 4TNV94 (2.8L) and 4TNV98 (3.3L) are different displacement variants but share the same intake manifold gasket.

Failure symptoms: air leak at the intake manifold (whistling/hissing), loss of boost pressure on turbocharged models, rough idle, reduced power, or soot deposits around the intake manifold flanges. The paper gasket material can deteriorate from heat and oil exposure. When replacing, clean both the manifold and head surfaces thoroughly. Inspect the manifold for warping or cracks. Torque bolts evenly per the Yanmar service manual.

⚠️ INTAKE manifold gasket — not exhaust or valve cover. Verify 4TNV94/4TNV98 engine.
