Description
When your old Allis Chalmers starts knocking or the oil pressure drops, worn rod bearings are often the culprit. This kit gives you everything you need to get those connecting rods running smooth again with proper clearances. Whether you’re working on a WD, WD45, or WF, this undersized bearing set compensates for a crankshaft that’s been turned and machined during rebuild work.
What You’re Getting
- Complete set of rod bearings sized .010 inch under standard for machined crankshafts
- Quality construction that meets the demands of hard-working farm tractors
- Precise fit that restores proper oil clearances and pressure
- Everything needed for one complete engine rebuild of the connecting rod assembly
Built for Real Farm Work
These bearings are engineered for the 138 CID and 149 CID 4-cylinder gas engines that powered thousands of Allis Chalmers tractors through decades of field work. Whether you’re running a WD for hay work, a WD45 for row crops, or a WF for general farm duties, these are the same quality bearings that keep these reliable old tractors running strong.
Made to Last
Farm tractors work hard and need bearings that can handle the load. This TISCO kit is built to handle the constant stress of PTO work, heavy pulling, and long days in the field. The precision machining ensures proper oil flow and heat dissipation to keep your engine running cool and smooth.
Good to Know
The .010 undersized specification means your crankshaft journals have been machined .010 inch smaller than standard—common practice during engine rebuilds. Always measure your crank journals with a micrometer to confirm the bearing size you need. Engine bearings must be ordered separately from other engine kit components, so make sure you’ve got everything for your rebuild before you start tearing down.
