Issue Description:

As a running change, Ingersoll Rand is updating the Motor End Plates on all MLK and HLK hoists.  Part numbers 03193091 (MR-12) and 03193075 (MR-11) will not change. Old and new end plates can be used interchangeably.

There is/was no functional or quality issue that required the update of the motor end plates.  It is solely a manufacturability update only.  The concept is the same as is used on the CLK-Series hoist motor end plates and was proven to produce equivalent performance with the prior design before being implemented.  The two existing air channels have been exposed on the surface of the end plates as shown in the “New Revision” photo below.
