7. Connecting Mark 7® Crank To 650 Ram
Clean the Dillon knuckle pin with alcohol and coat the surface with fresh synthetic multi-purpose
grease. Add grease to the contact points on the Mark 7® knuckle and insert the pin through the
crank and knuckle and lock in place with the set screw.
Figure 12: Installing Mark 7® Knuckle to Crank.
There are 2X set screws on the lower crank that lock it to drive shaft. Due to variations in the
650 press these may need to be backed out in order to line up the 650 ram to the Mark 7®
knuckle properly.
