Description

When you start hearing that telltale knock coming from under the hood, especially when you’re pulling heavy or climbing hills, worn connecting rod bearings are usually the culprit. These critical bearings keep your connecting rods moving smoothly and protect your crankshaft from expensive damage. Getting fresh bearings installed gets your John Deere back to running strong and reliable when there’s work to be done.

What You’re Getting

Pair of .020 inch oversize bearings for rebuilt engines with machined crankshafts
TISCO quality construction that meets original equipment standards
Proper bearing material designed to handle agricultural engine conditions
Direct replacement for AR27628R-10 with precise fit and clearances

Built for Real Farm Work

These bearings fit a wide range of John Deere engines from the smaller 201 and 227 cubic inch gas engines up through the big 466 cubic inch diesels. Whether you’re running a utility tractor through daily chores or pushing a larger machine through heavy field work, these engines take serious punishment from constant loads, temperature swings, and the dust and contamination that come with farm life.

Made to Last

These are built with bearing materials that resist fatigue and maintain proper oil clearances even under the temperature swings and contamination that agricultural engines face. The .020 oversize specification means they’re designed for engines where the crankshaft has been turned to restore proper journal dimensions during a rebuild.

Installation Notes

Installing connecting rod bearings requires complete engine disassembly and is definitely a job for someone with engine rebuilding experience. Always check bearing clearances with plastigauge before final assembly to ensure everything’s within spec. This is also the perfect time to inspect your crankshaft journals, connecting rods, and other internal engine components while everything’s apart.
