AVR Power trucks from GP-9 are dismantled for major overhaul. We re-machined and added two more set screws for more grip on the axles. Locomotive has seen five years of service including five winters. All set screws bolts and fasteners are being tightened and checked. Brake system will be adjusted, bearings are being checked and re-greased, all keys are being replaced. Gear boxes will be lubricated and checked.
