When that reliable old Perkins AD3-152 starts knocking or showing low oil pressure, worn rod bearings are often the culprit. This 3-cylinder diesel has been the heart of countless Massey Ferguson tractors for decades, but like any hardworking engine, the bearings eventually need attention. This .030 oversized rod bearing set gets your engine back to proper tolerances and ready for years more service.
What You’re Getting
- Complete set of rod bearings sized .030 oversized to restore proper oil clearance
- Precision-manufactured by TISCO to meet or exceed OEM specifications
- Direct replacement for original bearings once the crankshaft is turned to .030 undersize
- Complete kit includes all bearings needed for the 3-cylinder AD3-152 engine
Built for Real Farm Work
The Perkins AD3-152 powers many beloved Massey Ferguson tractors including the 135, 148, and others from that era. These 45-horsepower workhorses have handled everything from hay operations to loader work, and when properly maintained, they’ll keep running for decades. This bearing set is designed for the same demanding agricultural use that made these engines legendary.
Made to Last
Rod bearings take tremendous loads in any diesel engine, especially when you’re pulling implements or working under load. These TISCO bearings are manufactured with quality materials and precise tolerances to handle the stress and heat of continuous farm operation. They’re built to provide the oil film thickness and durability your rebuilt engine needs.
Good to Know
This .030 bearing set requires the crankshaft to be machined .030 undersize by a qualified machine shop before installation. Always check crankshaft journals carefully and measure clearances during assembly. If you’re doing a complete rebuild, consider checking the main bearings and other wear items at the same time.
