Rework Procedure

1.1. Use a tooling that has an open ended spanner jaw which enables access to the bolts (See Image 1.1.1).

Image1.1.1

1.2. Set the torque wrench to the static torque spec of 48 N.m (See Image 1.2.1).

Image1.2.1

1.3. Check each bolt on the head of the A-Frame (See Image 1.3.1). Note, depending on how the machine is sitting, this may not be possible to access one of the bolt but if all the other pass the test then the joint will be OK. If the test is not successful, perform step 2.

Image1.3.1

2. If the test was not successful, rework the A-frame bearing housing as described in M0102727, Special Instruction, "Rework Procedure for A-Frame Bearing Housing on Certain 700 Series Articulated Trucks".
