What is the purpose of a connecting rod bushing?

In a connecting rod assembly, this bushing is a wear part that helps guide the assembly and ensure proper fit. When replacing it, the goal is to find a part number that matches both the measured dimensions and the specific engine application. With this type of part, selecting the wrong variant can result in improper installation, even if the tractor belongs to the correct series.

The dimensional specifications and part number to verify

Part number R74008 identifies this bushing when searching for a compatible replacement part. However, the dimensions 47.655 x 47.681 mm remain the most immediate point of verification.

Why do some compatibility listings mention 6081H, 6081T, USA, or MEX?

These designations are used to distinguish between engine versions or market variants within the same John Deere model. They are important for selecting the correct bushing, for example on the 7710, 7810, 8100, 8200, or 8300, where compatibility also depends on the engine code or a serial number threshold.
