Using a ring-set intended for a bore only 0.010" or 0.020" won't automatically lead to broken rings. The reasons for rings breaking will more likely relate to installation problems - either not using a good quality ring expander when mounting them onto a piston or not using a good quality ring compressor when fitting them into a bore.

If the starter is crashing into the flywheel and then turning the motor over it will give you a grinding noise. I would get a pack of shims out of the help section and install one of the thinner ones and keep going up until the noise goes away.

• Adding AEGIS® Ring Technology to any motor repair for VFD driven motors is the best practice for motor shaft grounding in order to protect bearings from shaft voltages and bearing currents. • In addition to AEGIS® rings, motors above 100 HP (75kW) should have the opposite bearing isolated to prevent high frequency circulating currents.
