Chain drilling the saddle tank ends. |
After a couple of runs, I found that the pins which run through the expansion link die blocks were working loose and would occasionally jam. I machined up a new set of pins with a flange at one end and a thread fo a nut at the other which fixed the problem. Also, the drain cock lever in the cab is difficult to reach, so I made up a new one which protrudes back into the cab. |
