All GMN Spindle Repairs are test run to maximum rpm
GMN Spindles are initially ran at 5% of maximum speed.
Bearing Temp & vibration are checked.  Once verified to be with  OEM specs,
the rpm is increased to 10% of max. rpm.
All spindle units are checked before & during the increase of rpm at all intervals
Once they are proven to be within OEM specs they are increased by 10% intervals
of the max rpm until achieved.
When max rpm is achieved the spindle is ran for 1-2 hours
Bearings are monitored for velocity and displacement
Only when bearing temperatures & the vibration analysis readings are within OEM spec is the unit approved for
shipment.
