Description
When your engine starts burning oil, losing compression, or developing that telltale knock from worn cylinder bores, you don’t need to scrap the whole block or hunt down a replacement engine. This cylinder repair sleeve gives you a solid fix that’ll get your Cummins B series engine back to running strong and pulling hard when you need it most.
What You’re Getting
- Direct replacement sleeve designed specifically for Cummins B series engines
- Restores proper cylinder bore dimensions and compression specs
- Durable construction handles the high torque output of these workhorse engines
- Professional-grade repair solution that’s more cost-effective than engine replacement
- Machine shop installation brings worn cylinders back to like-new condition
Built for Real Farm Work
This sleeve fits the Cummins B series engines found in Case IH Maxxum tractors from the 5120 through 5250 models, plus the MX100 through MX170 series. These are the tractors doing the heavy lifting on farms – pulling big implements through tough ground, running loaders all day, and powering through harvest when every hour counts.
Made to Last
Engine sleeves are precision-made components that need to handle thousands of hours of combustion cycles, thermal expansion, and the constant pressure from pistons doing their job. This sleeve is manufactured to OEM specifications with the metallurgy and tolerances your Cummins B series engine was designed around.
Good to Know
Installing cylinder sleeves is a machine shop job that requires proper boring equipment, torque specs, and clearance measurements. Most shops can handle this work, but it’s worth finding one familiar with ag engines. While you’re having the work done, it’s smart to check your pistons and rings – if one cylinder needed sleeving, the others might not be far behind.
