Description
When you’re hearing that telltale knock from under the hood or noticing blue smoke on startup, worn pistons are usually the culprit. Lost compression means lost power, and nobody’s got time for a tractor that can’t pull its weight when there’s work to do. This standard bore piston gets your Cummins B Series engine back to factory specs and running like it should.
Key Features
- Standard bore sizing maintains original compression ratio for full power output
- Designed for turbocharged applications to handle the extra heat and pressure
- Precision-engineered crown and ring lands for proper combustion chamber sealing
- Quality casting handles the demands of agricultural diesel operation
- Direct OEM replacement – no machine work needed on standard bore engines
Built for Real Farm Work
This piston fits Case IH Maxxum series tractors and other equipment powered by Cummins B Series turbocharged diesel engines. Whether you’re running a 5120 on hay equipment, a 5140 pulling cultivation tools, or a 5150 on heavy tillage, these are the workhorses that power through long days in tough conditions.
Made to Last
Cummins B Series engines are known for their durability, and this piston maintains that reputation. The alloy construction handles the thermal cycling from cold morning starts to full-load field work, while the precision machining ensures proper ring sealing for years of reliable service.
Installation Notes
Installing pistons is a job for the winter shop when you’ve got time to do it right. Make sure to check your cylinder bore condition first – if it’s worn beyond standard tolerances, you’ll need oversized pistons and a machine shop visit. Don’t forget to replace the rings, pins, and bearings while you’re in there.
