Repair Project # 2

Our customer brought us two transmission housings out of an Atlas Copco L6. The bearings had been worn so badly that the new bearings would fall right thru when installed. To fix this we bored open the housings large enough to accept a large enough sleeve to hold the bearings properly. These sleeves were then pressed with a .002 press, a thread locking solution was installed and 3 Dutchmen Set Screws were installed. The sleeves were then honed  for a proper fit on the bearing.
