Description
When your Perkins AD3-152 starts losing compression or running rough on one cylinder, worn intake valves are often the culprit. These valves take a beating from hot exhaust gases and constant opening and closing, eventually developing pits or warping that lets compression slip away. This replacement intake valve gets your three-cylinder back to running smooth and pulling strong.
What You’re Getting
- Quality TISCO construction built to handle the heat and pressure of diesel combustion
- Proper valve dimensions and seating angles for reliable compression sealing
- Heat-treated stem and face materials that resist warping and pitting
- Direct replacement – no modifications needed to install in your AD3-152 head
Built for Real Farm Work
The Perkins AD3.152 three-cylinder engine powered legendary tractors like the Massey Ferguson 135, delivering 45 horsepower for decades of reliable farm work. Whether you’re running a loader, cutting hay, or pulling implements, this engine needs proper valve sealing to maintain the compression that delivers full power when you need it most.
Made to Last
Farm engines work hard in dusty, demanding conditions where inferior valves fail quickly. This valve features proper metallurgy and heat treatment to handle the constant thermal cycling that cracks cheaper alternatives. The precision-ground seating surfaces ensure a tight seal that maintains compression over thousands of operating hours.
Good to Know
Valve replacement requires cylinder head work, so it’s a good time to check valve guides, springs, and seats while you’re in there. Three valves are used per engine in the AD3-152, so if one’s worn, the others likely need attention too. A valve job done right keeps your engine running strong for years to come.
