The JTEKT Machinery Standard
- Motor air-cooling is checked for proper flow
- Motor Horsepower is checked to meet OEM specifications
- Every seal and O-ring is inspected for possible failure and replaced
- Components are cleaned, inspected, measured, balanced, and reassembled to the original factory print
- Worn drawbar springs are discarded and replaced with new OEM springs
- Pneumatic, hydraulic and lubrication ports are thoroughly cleaned by hand ensuring all contaminants are eliminated from within the housing
- Hydraulic cylinders, lubrication systems, and flow meters are leak-checked and individually inspected for proper operation and force
- Peak-to-peak vibration numbers are monitored (if the numbers exceed certain tolerances, the process is stopped)
- Bearing and motor cooling systems are checked for proper operation and stabilized temperatures
- Temperature of each bearing is monitored through the exhaust ports during run-in
- Each unit is balanced on a two-plane, hard bearing Schneck balancer to a ISO grade G1.0 tolerance or better
- Findings are backed up with written documentation and photographs. This data is also documented and available for review
- Any components from the damaged spindle that can be reliably used are reworked to OEM specifications
- Any components that are deemed unusable are replaced with an original JTEKT Machinery part
