  • Page 29: Mechanical End Assembly

    MDX [en-US]  In Limited End Float (LEF) bearing assemblies the drive end radial bearing will be a single row taper roller bearing. These bearings are hot when installed and are press fitted to the shaft. It is difficult to remove them from the shaft undamaged, and they should be removed only if a bearing needs to be replaced.

  • Page 30: Closing The Housing

    MDX [en-US]  The drive end radial bearing next to the thrust bearing should be mounted with its inner race in direct contact with the split ring (or split thrust collar). If it is a taper lock type, first position it on the shaft while loosely mounted on its adapter. The locknut should then be tightened until the internal bearing clearance as determined with a feeler gauge is equal to the actual un-mounted clearance minus the required decrease as specified in the chart above.
