Direct Replacement Fuel Injection Pump — OEM-Spec for Yanmar 3TNA72 Engine | John Deere Compact Equipment

The Yanmar 3TNA72 is the compact diesel engine at the heart of a wide range of John Deere equipment — from the 332 riding mower and 6X4 utility vehicle to the 655, 856, 375, 3375, 2653A, and 2243 commercial turf and grounds machines. The fuel injection pump is the most critical component in the fuel system: it generates the high pressure that drives injection timing and fuel delivery to every cylinder. When it fails, the symptoms escalate quickly — rough running and hard starts give way to severe power loss and eventually a no-start condition that takes your equipment completely out of service. This direct-fit replacement pump (AM875035) is engineered to Yanmar 3TNA72 specifications, restoring factory injection pressure and timing across all eight John Deere compact equipment models.
