Part Number Description
6V-4876(1) Lubricant
(1) The use of 186-1531 Lubricant is necessary in EAME.Inspection of Connecting Rods
The connecting rod should be inspected for physical damage. The connecting rod should be inspected for mechanical damage. Refer to the "Visual Inspection" Section for more information.

Bolt tightening sequence
Use the correct torque turn procedure in order to tighten the bolts before you measure the bore for the crankshaft. The bearing must be removed from the bore before measuring the bore.
Lubricate the bolt threads and the seating face of the bolt with 6V-4876 Lubricant or 186-1531 Lubricant before assembling the connecting rod.
Assemble the washer onto the bolt so the bolt head is centered in the counterbore of the washer.
Tighten bolt (1) to a torque of 190 10 N m (140.0 7.0 lb ft).
Tighten bolt (4) to a torque of 190 10 N m (140.0 7.0 lb ft).
Tighten bolt (3) to a torque of 190 10 N m (140.0 7.0 lb ft).
Tighten bolt (2) to a torque of 190 10 N m (140.0 7.0 lb ft).
Again, tighten bolt (1) to a torque of 190 10 N m (140.0 7.0 lb ft).
Again, tighten bolt (4) to a torque of 190 10 N m (140.0 7.0 lb ft).
Tighten bolt (1) for an additional 90 degrees.
Tighten bolt (4) for an additional 90 degrees.
Again, tighten bolt (3) to a torque of 190 10 N m (140.0 7.0 lb ft).
Again, tighten bolt (2) to a torque of 190 10 N m (140.0 7.0 lb ft).
Tighten bolt (3) for an additional 90 degrees.
Tighten bolt (2) for an additional 90 degrees.

Angles of measurement for the crankshaft bore
Use a dial bore gauge in order to measure the bore for the crankshaft. Measurements should be taken at 0 degrees, 40 degrees, 50 degrees, 90 degrees, and 130 degrees. Refer to Illustration 212.These measurements should be taken in 2 planes at each angle. Take the average of the top and the bottom measurement at each angle.The roundness of the bore is the difference between the maximum and minimum dimensions. During extended hours of operation, the bore for the crankshaft closes at the joint that is serrated. The maximum allowable roundness for a used connecting rod is 0.330 mm (0.0130 inch). Measurements that exceed the specifications will require replacement of the connecting rod.Record the measurements in Table 74. Submit the data to Caterpillar Marine Customer Service Department.
