So I've been working this motor grader. The differential lock system had been overheated for a long time and all the hoses, seals, and pump were toast, also, I had to drop the rear axle and replace the pinion seals. Finally, got it all put back together and went for a test drive. Put the blade in the dirt to lift one tandem off the ground to check the diff lock and caught a gas line that was only like an inch from the surface. Then, when I got out to check things out I noticed something let go on the front of the engine and started spraying coolant everywhere. Needless to say, I'm drinking beers tonight.
