Description
When you’re hearing valve noise or dealing with low compression, worn valve springs are often the culprit. These little coiled workhorses keep your valves sealing tight and opening cleanly—and when they weaken or break, your engine’s performance goes downhill fast. Six springs handle the intake and exhaust duties in your AD3-152 3-cylinder diesel, and this replacement gets your tractor breathing properly again.
What You’re Getting
- Proper spring tension to ensure positive valve seating and smooth operation
- Quality TISCO construction that matches original equipment specs
- Direct replacement design—no modifications or guesswork needed
- Set of springs engineered specifically for the demanding duty cycle of farm tractors
Built for Real Farm Work
The Perkins AD3-152 is a workhorse engine that’s powered countless tractors over the years, from compact utility machines to mid-size row-crop tractors. These engines are found in Massey Ferguson 35/135 series tractors and other makes that relied on this proven 3-cylinder design for dependable field work, whether you’re cultivating, mowing, or running a PTO-driven implement.
Made to Last
Farm engines run long hours under varying loads and conditions, so valve springs need to maintain their tension through thousands of cycles. These replacement springs are manufactured to handle the heat, vibration, and constant compression cycles that come with agricultural use, ensuring your valves operate reliably season after season.
Good to Know
Installing valve springs requires removing the cylinder head, so it’s a good time to check valve clearances and inspect the valve seats while you’re in there. If you’re replacing springs due to a broken one, be sure to check for any metal pieces that might have fallen into the cylinder.
