Description
When you hear that distinctive knocking sound from your engine, especially under load or during startup, it’s usually those connecting rod bearings telling you they’ve had enough. These bearings sit between the connecting rod and the crankshaft, handling the explosive forces that turn fuel into power. When they wear out, you’re looking at expensive engine damage if you keep running—but catching them early means a rebuild instead of a complete replacement.
What You’re Getting
- 30 thousandths oversize bearings for engines that have been machined for repair
- Quality construction designed to handle the high pressures of diesel operation
- Precision-manufactured to restore proper oil clearances and engine performance
- Direct replacement for worn bearings in Perkins A4.212, A4.236, T4.236, and A4.248 engines
Built for Real Farm Work
These bearings fit the dependable Perkins engines found in many Massey Ferguson tractors from the 100, 200, 300, 500, and 600 series, along with various Landini models and industrial applications. Whether you’re running a mid-range 175 for general farm work or a bigger 690 for heavy tillage, these engines are known for their durability and fuel efficiency when properly maintained.
Made to Last
Perkins engines are built to handle the demanding conditions of farm work, and these replacement bearings maintain that same standard. They’re manufactured to withstand the constant pressure cycles and temperature swings that come with diesel operation, giving you the reliability you need during busy seasons.
Installation Notes
This is a major engine repair that requires complete disassembly and proper machining to accept the oversized bearings. You’ll need to have the crankshaft journals checked and potentially ground to the proper specifications. It’s also smart to replace the main bearings, gaskets, and seals while you have the engine apart—doing it all at once saves labor and ensures everything works together properly.
