PROBLEM

Show/hide table

The 380-7674 Bearings should only be used with D9R and D9T Equalizer Bars with a center lubrication groove as shown in Image 1.1.1. Oil or grease will not reach the bearing load zone if a 380-7674 Bearing is installed in a D9R or D9T Equalizer Bar without a center lubrication groove. A 117-4013 Bearing should be used instead of a 380-7674 Bearing on an equalizer bar without a center lubrication groove.

NOTE: Equalizer bars with a center lubrication groove were first manufactured in December of 2011.
