Ok, here are some photos from the day's work. First is a shot of the bent M6 hex head screws we used with a 0.750" diameter iron pipe to restrain the crank. This didn't work at all, and actually caused the chain to slip a few teeth on the camshaft as the screws bent so much the crank.
The next is a shot of the strongback we made from a piece of flat bar. We made a template of the two bolt holes from the dynamic balancer and then made a pad using a bit of scrap plywood and a tip of the flat bar we cut off, for the strongback to bear on on the right side frame rail, under the spot the self levelling system hydaulic oil reservoir sits.
We then had to make stacks of washers act as spacers since the only M6 bolts I had were longer ones, with a pair of 0.375" nuts, one on each of the two bolts, acting as spacers to make a stand off for the lip feature on the dynamic balancer. We tightened the screws into the dynamic balancer by hand. We used a Sears Craftsman 24" breaker bar with a 0.500" drive, which we slipped a 1.0" diameter 3 foot long extension pipe over. This worked, but still bent the fasteners slightly, and, unlike the "stretch bolts" in the head, this big bear didn't just "pop" loose. It took about half a turn to relax the stretch on that thing.
More to come. Jim
