Description
When you’re hearing knocking sounds from your Allis Chalmers engine or noticing metal shavings in the oil, it’s time to address those worn connecting rod bearings before they take out the whole crankshaft. These bearings take a beating every time the engine fires, and after years of faithful service, they wear down and need replacement. This complete rod bearing kit gets your engine running smooth and quiet again.
What You’re Getting
- Complete set of standard-size connecting rod bearings for all four cylinders
- Precision-manufactured to OEM specifications for proper oil clearance and fit
- Quality materials that handle the heat and pressure of hard-working gas engines
- Everything you need in one kit—no hunting around for individual bearings
Built for Real Farm Work
This kit fits the 138 cubic inch and 149 cubic inch 4-cylinder gas engines that powered many of the classic Allis Chalmers tractors from the era when these machines were built to last. These engines were workhorses that spent long days pulling plows, running balers, and powering whatever implement you hooked behind them.
Made to Last
TISCO builds these bearings to handle the punishment that comes with engine work under load. The materials and manufacturing meet the standards that keep these vintage engines running for decades when properly maintained.
Installation Notes
This is a job for someone comfortable with engine teardown—you’ll need to pull the oil pan and remove the connecting rods to get to the old bearings. Take your time measuring clearances and checking the crankshaft for wear while you’re in there. If the crank needs attention, now’s the time to deal with it.
