In this video I finished the job of repairing the New Holland baler cranks.
Firstly the jig needed line boring to size, to do this I used the new S power line borer. After the 2 end supports were done, I transferred the jig onto the Huron milling machine to bore the centre support to size. This completed the jig.
Next up I test fitted the crank into the jig to ensure it fit and also to get some measurements of the overall length. The old journals were then plasma gouged out and cleaned up with the grinder before refitting back into the jig ready for the repair. The new journal was preheated and then welded around.
Same process again on crank number 2.
Lastly I fitted some bearing onto the cranks to check the runout, there was some runout but well within a usable tolerance.
Hope you enjoyed the video.
Thanks for watching.
