TECHNICAL SPECIFICATION NO. VE-23-055

Amend as follows:

Section 4.12

Add Section 4.12 Contract Bid Option #8 Traction Motor Combo Overhaul (5GEB15)

A. The Authority will identify via serial number the traction motor combos for overhaul.

B. The Contractor shall clean, inspect, overhaul, test, and assemble the traction motor combos according to the OEM Running and Heavy Maintenance Manuals.

C. Work shall include but not limited to Traction Motor, Traction Motor Leads, Gear Case, Gear, U-tube, Bearings, Bearing Housing, caps, cups, collars, housings, spacers, grease and all miscellaneous parts to assemble a complete wheel/axle/motor assembly. Wheel and axle assembly overhaul are not included in the scope but must be properly stored and maintained per

Section 22.5 Parts Preservation Plan. All hardware, seals, gaskets, and bearings shall be 100% replaced with new.

D. In addition to following all OEM cleaning, inspecting, testing, and overhaul requirements, all

5GEB15B1 motors shall undergo the Vacuum Pressure Impregnation (VPI) process to ensure enhanced insulation, durability, and operational reliability. The VPI process shall include the following steps: pre-inspection of each motor to identify any damages or deficiencies;

disassembly and thorough cleaning to remove contaminants; and baking of components to eliminate moisture. The process shall then employ a vacuum to remove air and moisture from the windings, followed by the application of OEM-specified insulating resin under pressure to ensure complete penetration into the windings. Components must be cured in a controlled oven environment to solidify the resin and achieve optimal insulation integrity. Post-VPI, all motors shall be subjected to comprehensive electrical and operational testing to verify compliance with technical and reliability standards. The VPI process shall strictly adhere to OEM specifications, including resin type, pressure levels, temperature, and curing times, ensuring consistent performance across all treated motors.
