Use 334-0519 Molylube Anti-Seize Lubricant to lubricate the threads of the bolts, of the nuts, and the seating face of the nut after the bolt for the connecting rod is installed in the connecting rod.Note: This torque procedure was developed with 334-0519 Molylube Anti-Seize Lubricant. The use of any other lubricant may result in an incorrect torque value and in subsequent failure of the connecting rod bolt.
Turn all four nuts by hand until the nuts contact the face of the cap. No resistance should be felt that would indicate thread damage or debris in the joint. Threading the nuts by hand will provide an opportunity to identify problems with the threads. If the nuts and/or bolts cannot be threaded by hand, the nuts and/or bolts must be replaced. Do not use an impact wrench to install the nuts up to the face of the cap.

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.
