Over the Thanksgiving weekend I got an Earthquake Model 3365. A neighbor of my mom had it out on the side of street with a sign saying free to a good home. The woman that helps my mom ask if I could use it so it was at my moms waiting for me. The other information on it was that the gears are stripped. When I got back home with it I took the lower gear box a part to find out what happened. The brass gear is stripped & the key for the cross shaft is missing.
The parts in the gear box.
The gear with the bearing mount on the shaft between the 2 slots.
The clips holds this together & they seem to be very easy to bend.
The other shaft seem not to be damaged & one half of the gear box.
The gear, bearings, & clips are all inside the gear box. When I was taking this a part I noticed that the ears of one clip was showing out side of the gear box. My thought on how this failed is that the clips came out of the slots on the shaft allowing the bearings to separate from the gear. This gap allowed the key to come out of the gear as it was being ground away it jammed the gear to cause the damage to the gear. I found a place to purchase the gear for $55 & the key is $3. The clips are also offered for $3 each but do not know if they are needed. Now trying to decide what is the best way to keep the clips in the slots. One thought would be a wire in the 2 holes to lock the clip in or a spot weld to hold the clip. I am not sure if there is clearance for a safety wire. Any ideas on this would be helpful. After the holidays I will get the parts ordered then try putting this back together. I had to do some cleaning on the carb to get the motor to run then ran it long enough for an oil change so it is ready.
