Application: Main bearing shells for a diesel internal combustion engine, fastened with 4 bolts per shell.
HYTORC tooling: Avanti-1 with special dual nut drive/reaction arm.
Old method: Manual torque wrench or 1-MXT.
Problem in old situation: During revision, there is very little space around the engine and to save time as few parts as possible are to be removed. The main bearing shells have therefore been loosened through an inspection hatch on the side of the engine. Due to the limited space, this was largely done on intuition and it was not always safe to operate the MXT. There is also no space for a manual torque wrench through the inspection hatch.
Benefits: With an Avanti-1 with a dual nut drive the mechanic can now turn a bolt without any risk of pinching, while supporting itself on the adjacent bolt.
