It is possible to buy a gear from a Black and Decker service center that will press on to the Fisher-Price motor. Part #148579-00 $2.35 is available at your local parts dealer, just look in the yellow pages under power tools, repair. While they probably don't stock it they should be able to get it in less than a week. This gear has 10 teeth at a diametral pitch of 44 and mates with part #148373-00 $3.95 which is a cluster gear with 53 teeth at 44 DP on one side and a pinion of 8 teeth at 36 DP on the other side. This gear can mate with any of the following 3: part #148553-00 $7.05, 47 teeth; part #148561-00 $10.75, 35; or part #91246-00 $2.65, 17 teeth. The first two gears I mentioned are powdered metal, the next two are cut steel, and the last one is nylon. E-mail me if you want more details

Can anyone supply some pictures of this modification? Or, a detailed description. I assume the gears that you are replacing are inside the gear assembly some where between the motor output shaft and the transmission hub.

These gears are not drop in replacements, you would have to fabricate a new gearcase
