SunStar differential lock


Recommended Posts


I have a new to me SunStar 1692456 with only 383 hours on it. It was not properly maintained, but for someone familiar with this model, and with parts available, less of a problem. Did not notice it did not have differential lock until after a couple of months, would not of been  a deal breaker, just too new.  I have a spare D/A version 1691392 and was wondering the easiest way to do a differential swop. Does it need to be a complete swop or can I get away with just adding the linkage to current unit circa 1996, if the internals are there. I know I have a to do a frame cut out for differential lock lever.

Before demotion to a parts tractor, the high gear would slip often so I kept it in low gear. I will check the linkage when I get into frame, maybe something was loose, I hope it's something simple. Any advice is welcomed?
