Craftsman Snowblower Full Service & Auger Gearbox Oil Leak Repair: Model# 247.888740
Rear oil seal on the auger gear box was damaged from debris being caught on the impeller axle. Replaced the seal and refilled with 80W-90 gear oil. While I had it apart the customer wanted me to change the belts simply because I already had it apart. Also had to change out the auger bearing as it was noisy.
Customer is one of the better ones as he religiously drains the fuel every year, no carburetor issues with this machine. Refilled it with some Trufuel 4 cycle for testing so he wont have problems when the first snow of the season comes in the few months.
