## Discrepancy

DURING DISASSEMBLY OF BEARING LINER FROM THE HOUSING, A SHIM WAS FOUND AROUND THE HOUSING INSIDE DIAMETER WHERE THE BEARING LINER SITS.  THE HOUSING I.D. WHERE BEARING LINER SITS IS OVERSIZED AND SHIM WAS INSTALLED BY UNKNOWN SHOP TO ACCOMMODATE THE NEW BEARING LINER.  THIS PRACTICE IS NOT ACCEPTABLE WITH THE MANUFACTURER'S SPECS.
