My snowblower auger slurped up a log chain and broke the gear case and auger drive gear.
I removed the three forward most bolts on each side of the snowblowers main body, just behind the impeller body to separate the main body from the auger/impeller body. Then, I removed the auger/impeller drive pulley from the impeller shaft. Remove the 3 bolts at both ends of the auger shaft, pull the auger and impeller assembly out of the body, remove the shear bolts from the auger shaft, and slide the augers off of the shaft. Remove bolts from the gearcase, separate the case, remove bushings and inspect them for any damage, inspect the worm gear on impeller shaft for any damage, use a press or 18' pipe to press or drive off the brass auger gear, inspect the woodruff key and its groove in the auger shaft. Replace any bent, deeply scratched/grooved, or broken parts and be sure to order a new gear case gasket. Drive out and inspect the seals from the old gear cases. The new gear case has a provision for a fill-plug, but threads need to be tapped with a 3/8" coarse thread tap. The bushings have a flat edge on their flanges that align with flat bosses in case. Reverse the procedure for reassembly. tighten gear case bolts to 15-19 ft/lbs, fill the case with Duraplate white lube.
