Description
When your Perkins 1004.4 engine starts showing its age—burning oil, losing compression, or making noises it shouldn’t—you’ve got a choice. You can keep patching things up and hoping for the best, or you can do it right the first time with a complete overhaul that’ll give you thousands more hours of reliable service. This kit has everything you need to bring that engine back to like-new condition.
What You’re Getting
- Complete cylinder rebuild components including pistons, rings, and bushings for all four cylinders
- Full bearing set for both big end and main bearings, plus thrust washers for proper crankshaft alignment
- Complete gasket and seal package including head gasket, sump gasket, and both front and rear crankshaft seals
- All connecting rod hardware with new bolts and nuts—no reusing stretched fasteners
- Camshaft bearing to ensure proper valve timing and oil pressure
Built for Real Farm Work
These 1004.4 engines are known for reliability and are found in Massey Ferguson 4200 and 6100 series tractors that handle everything from hay operations to heavy tillage work. Whether you’re running a 4225 on the dairy or a 6150 pulling deep tillage equipment, this engine has to deliver consistent power day after day. A proper overhaul with quality components ensures you’ll get that reliability for years to come.
Made to Last
This isn’t a budget rebuild kit with shortcuts. Every component meets or exceeds factory specifications, from the precision-machined pistons to the multi-layer steel head gasket. The bearings are engineered to handle the loads these engines see in agricultural service, while the seals use materials that resist the temperature cycling and contamination common in farm environments.
Good to Know
An engine overhaul is a big job, but it’s straightforward if you take your time and follow proper procedures. Make sure to check crankshaft journals for wear and have them ground if needed—new bearings won’t fix a worn crank. Clean everything meticulously, use proper torque specifications, and don’t rush the reassembly. A quality overhaul done right should give you 8,000-10,000 hours of service.
