During the process of replacing the silent blocks several specialist tools and jigs are advised in the service book. Several of these I have made and have proved very useful. Reading the manual, after assembly of the items in the above photograph the end ring nuts have to be tightened in excess of 180ft lbs. I did not fancy using a c-spanner as I could not monitor the torque so I have modified a socket to fit the nut and also it can be used with my existing torque wrench.
