Description

When your Allis Chalmers starts losing power, smoking more than usual, or burning oil, it’s often the valves telling you they’ve had enough. The reliable Perkins AD3.152 three-cylinder engine has been a farm favorite for decades, but after thousands of hours of work, valve seats wear and valve seals start letting oil slip past. This complete valve overhaul kit gets your engine breathing properly again and puts the power back where it belongs.

What You’re Getting

Complete set of intake and exhaust valves sized for your 3-cylinder Perkins diesel
Valve springs that maintain proper seating pressure season after season
Valve guides that keep everything aligned for smooth operation
Valve keepers that lock everything in place and won’t let go
Everything needed for one complete AD3-152 engine rebuild

Built for Real Farm Work

This kit fits Allis Chalmers tractors powered by the reliable Perkins AD3.152 3-cylinder diesel delivering 45.5 horsepower. Whether you’re running a loader, pulling implements, or handling daily farm chores, these orange workhorses need valves that seal tight and open fully. The AD3-152 was built to run all day without complaint, and with fresh valve components, it’ll do just that for another generation.

Made to Last

TISCO builds these valve components to handle the heat and pressure cycles that come with diesel operation. The valves are made from materials that resist the high combustion temperatures, while the springs maintain their tension through countless compression cycles. These aren’t cheap replacements—they’re built to restore your engine to original performance standards.

Good to Know

This is a complete valve train overhaul, so you’ll want to have the cylinder head off for proper installation. It’s a good time to check valve seat condition and consider having them reground if needed. Quality valve train components are critical for protecting bearings, pistons, and other engine components, so don’t cut corners when it comes to valve work.
