Description
When your tractor starts losing power or running rough, one culprit that’s often overlooked is a worn inlet valve. This valve controls the air-fuel mixture entering each cylinder, and when it’s not sealing properly or has worn seating surfaces, you’ll notice poor performance, hard starting, and higher fuel consumption. The 45-degree angle on this valve is specifically designed to match the valve seat angle in your engine head for optimal sealing.
What You’re Getting
- Precision-machined valve with 45-degree seating angle for proper combustion chamber seal
- High-quality steel construction built to handle the heat and pressure of diesel engines
- Exact dimensions to match original specifications – no modifications needed
- Factory-correct stem diameter and length for proper valve train operation
- Heat-treated surfaces resist wear from repeated opening and closing cycles
Built for Workhorse Engines
This inlet valve fits the legendary Perkins AD3.152 three-cylinder and A4.203 four-cylinder engines that powered so many reliable farm tractors. These engines were known for their durability and fuel efficiency, whether you’re running a Massey Ferguson doing loader work, a combine harvester in the field, or industrial equipment that needs to run all day without complaint.
Made to Last
Engine valves take a beating from constant heat cycling and combustion pressure. This valve is manufactured from quality steel that’s been properly heat-treated to resist warping and maintain its sealing surfaces. The precise machining ensures it’ll seat properly in your cylinder head and provide years of reliable service.
Good to Know
Valve replacement typically requires removing the cylinder head and having a machine shop check valve seat condition and clearances. While you’re at it, it’s smart to replace all the valves together along with valve seals and springs. Always check valve-to-piston clearance when reassembling to prevent interference damage.
