Yeah that's what it looked like internally

I fixed it. Had to pull the box out to get my hands on it but I discovered it was a stuck bearing. Probably water from the last washdown. Even though I blow-dry all the cars after washing, there must have been some water seepage that sat on a bearing and probably created a rust spot. One hard turn of the shaft with the screwdriver and it came loose. I still pulled the gearbox apart to make sure there was no water leakage into the box and the gears were absolutely fine. I put it back together and it runs fine after 8 years.

It seems to be the only way. The box has seized sitting there for 8 years. The car was only ran twice since purchase and then stored. The engine started no problem after a few turns because I prepared it well for storage but the box seized. I'm going to have to pull it apart. Thanks anyway

Hey Guys Was just wondering if anybody has even encountered a seized box on a Sledgehammer S50 and if so, is there a trick to unsticking it. Car will not roll and it has me stumped as box will not turn Thanks, fellas
