TURBINE WHEEL & SHAFT ASSEMBLY REPAIR
SEAL AREA & BEARING JOURNAL
Minor turbine wheel vane damage can be repaired. Many ring grooves can be repaired; sometimes oversized rings can be installed. Shaft journals can often be undersized .005", .010", .015", 020". We can re-center and straighten turbine shafts. We repair the seal hub, including the ring groove area. We polish the shaft and dynamic balance.

2: Bearing journals should clean up at minimum of .015 undersize.
3: This area can have no damage. Maximum bend of .010.
4: Threads cannot be stripped. Maximum of .010 bend allowed.
