1     4     467-0537 Bolt As     Use the following procedure in order to tighten the connecting rod bolt:
1. Before assembly, assure that the retainer and bolt head are free from Molylube.
2. Before applying thread lubricant, install the bolt into the retainer plate and rod.
3. After installation of bolt, lubricate the threads of the bolt, nut, and contact face of the nut with Bell - Ray Molylube 67700.
4. 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 nut by hand provides 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.
5. Tighten all four nuts (2) to
105 20 N m (77 15 lb ft).
6. Tighten nut 1, 4, 2, and 3 in the sequence as shown in Illustration 3 to
340 15 N m (251 11 lb ft).
7. Again, tighten nut 2, 3, 1, and 4 in the sequence as shown in Illustration 3 to
340 15 N m (251 11 lb ft).
8. Again, tighten nut 1, 4, 2, and 3 in the sequence as shown in Illustration 3 to an angle of 180 5 degrees.
