Ariens 10,000 oil leak rear of differential to impeller

Ariens 910995 bucket, 910962 tractor is leaking gear oil from the rear of the differential going to the impeller, on the bucket. I have not split the blower from the tractor yet, so, I don't know what is involved with this seal replacement. I plan to take this apart this coming week end. I looked at a parts diagram (Partstree) and it looks like the seal is at the rear of the differential assembly. If that is the case, it looks like an straight forward replacement. Any help on what I will be getting into is appreciated.

FYI, that's not a differential . . . The output shaft (augur) is solid and thus speeds can not 'differ' . . . as would be the case for an actual 'differ'ential . . . .

I am not familiar with your snowblower, but generally the process is to separate the blower housing incorporating the impeller and auger from the tractor portion incorporating the engine and drivetrain. Remove the impeller pulley and bearing (or bushing) from the housing. Release the auger shaft supports at either side of the blower housing. Pull the auger and impeller out of the blower housing. Remove the augers from the shafts after removing the shear bolts. The impeller may be attached to the impeller shaft using bolts or pins which must be removed. The impeller may be rusted in place and need release oil or heat or both to remove it. The impeller shaft seal in the gear box can be removed using a screwdriver or screwing in a screw and pulling the seal out.

Clean up the impeller shaft and lubricate it and the seal and the gearbox opening and put the new seal (spring side toward the gearbox) over the shaft and press down to the gearbox housing. Using a washer on the seal and a tube to go over the shaft position the seal square in the opening of the gearbox and hammer straight down on the washer so the seal goes into place and flush with the housing. Now reassemble everything.

Since the impeller shaft is turning at 1,000 rpm approx and the augers are turning at 100 rpm the impeller seal will be the first to fail, especially if the support bearing (or bushing) has a bit of wear. The lubricant in the gearbox may be grease or hypoid gear oil or other oil. You will need to know the spec for the lubricant and you may want to replace it during this job. I have never had to replace the gears in the gearbox even in a 30 year old machine but you should check for play between the impeller shaft and auger shaft to see if the gears are in good condition.

Others with more experience with the gearbox may be able to help you. Replacing the seal took me half a day, but I work slowly.

Good luck

Try some Stens 00 grease in it before you take it apart, and try it out
