Attach. (1-Rework Procedure)Rework Procedure
Refer to the following instructions and illustrations. Replace the existing fuel lines and their related parts with the new fuel line groups.
To insure correct clamp locations, install left and right fuel line groups as assembled. However, if clamps are removed, mark locations to insure correct positions when reassembling.
On the 992C Wheel Loader, it is necessary to remove the 6N8322 Air Outlet Tube Assembly to be able to install the right bank fuel line group.
Tighten the fuel line clamp screws to a torque of 2.25 N m (20 lb in). Do not over tighten. Use a 6V6069 Torque Screwdriver or similar tool to tighten the screws.
