These PowerTech engines were built to handle heavy workloads, and when properly rebuilt with quality components, they'll deliver reliable service for thousands more hours of field work.

This major overhaul kit contains everything needed for a complete engine rebuild including sleeves, pistons, rings, pins, bushings, complete gasket set, and valve components. The heavy-duty piston design handles the stress of modern farming operations, while the included rod bolts ensure you're not reusing hardware that's been stretched beyond its limits.
Good to Know
Bearing sizes need to be specified when ordering - you'll want to measure your crankshaft journals to determine if you need standard, .010, or .020 rod bearings, and standard or .010 main bearings. This is precision work that's best handled by an experienced engine rebuilder who can properly check clearances and torque specifications. Plan on having your block checked for wear and deck height while you've got it apart.
