Kit, Motor Upgrade, E2, v3

The clamped upper bearing kit is available to upgrade your motor to the most current design on the E2 Type 12 Rainbow main units.

Upgrade for both the "Original" motor in the Gold version and also the "Direct-Support" motor design that was in both the Gold and early Silver version.

The "Original" motor design was effective serial number 1000000 with a start date of September 4th 2003 through serial number 1167459 and an end date of October 24th 2005.

The "Direct-Support" motor design was effective serial number 1167460 with a start date of October 25th 2005 through serial number 1450975 (rough estimate) and an end date of May 2009 (estimate).

If you have had an issue with the top bearing wearing out the "Rotor" (Armature), then you need to purchase this upgrade kit to prevent the issue in the future.

Easiest way to determine if you have the most current version is to look for the H610 "Upper Bearing Nut" that would be on the very top of the motor on the most current design.
