What does '0.030 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.030 inches smaller in diameter than standard size. This is necessary when the crankshaft journals have been machined down (ground undersize) during an engine rebuild to remove wear or damage. Using the correct undersize bearing ensures the proper oil clearance is maintained.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. It includes all the bearings needed for the connecting rods on your 4-134 engine, typically enough for all cylinders.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. Their main job is to reduce friction and wear by allowing the rod to rotate smoothly around the crankshaft journal, while also maintaining a precise oil clearance for lubrication.

Product Details

Already rebuilt the engine or just need to replace worn bearings? This ACL connecting rod bearing set is designed for your Jeep CJ5, CJ3, or CJ6 with the 4-134 (2.2L) engine. Connecting rod bearings are critical for keeping your crankshaft spinning smoothly within the engine block, and replacing them during an engine overhaul is standard practice to ensure longevity and proper oil clearance.

This set is manufactured by ACL, a well-known name in engine bearings. The bearings in this set are 0.030 inch undersize, which is important if your crankshaft has been machined down during a rebuild. Using the correct undersize bearing ensures the proper oil clearance is maintained between the rod and the crank journal, which is essential for oil pressure and lubrication. These bearings are built to meet the demands of the 4-134 engine, providing a solid option for your rebuild project.
