new bearing required precision leveling when repositioned. The past repair procedure was to weld <strong>and</strong><br />
machine to required dimension. This repair procedure was costly, caused heat distortion damage, <strong>and</strong><br />
created lengthy equipment downtime.<br />
Solution:<br />
The new bearing was generously coated with <strong>Devcon</strong>’s Paste Release Agent. Release Agent must be used<br />
for easy part separation or removal. The bearing was positioned <strong>and</strong> leveled using jack bolts. A metal strip<br />
was tack welded around the perimeter to contain Plastic Steel Liquid <strong>and</strong> prevent migration while curing.<br />
Plastic Steel Liquid was pumped between the surfaces using a Grayco manual pump. Following full cure,<br />
