Built for Real Farm Work
These bearings are designed for the 201 and 226 cubic inch four-cylinder gas engines that powered a wide range of Allis Chalmers tractors through the years. Whether you’re running a utility tractor for loader work or a row-crop machine for fieldwork, these engines were built to handle the steady demands of farm life.
Made to Last
TISCO doesn’t cut corners when it comes to engine internals. These bearings are manufactured to handle the heat, pressure, and constant rotation that comes with moving heavy loads and running long hours. The precision tolerances ensure proper oil clearance for reliable lubrication and long service life.
Installation Notes
This is a job for someone comfortable with engine work – you’ll need to drop the oil pan and remove the connecting rods. Check your crankshaft journals for wear and scoring before installing new bearings. If you’re doing the job, it’s smart to replace all four sets at once since they wear at similar rates.
