Default Stuck pinion

Drill the set screw out.The gear should pull off.You will ruin the pioion but have your motor out of the truck.

Take a flat blade screwdriver and pry it off . Had to do that a few times years ago .

actually i just bent my screwdriver. if that gives you an idea of how stuck it is... what the hell made this happen? will drilling the grub hole out make it easier? you know make it bigger?

did you put thread lock "red" in there or something? jeeze....if push come to shove, a "pinion puller" is probably your last bet before you have to toss the motor....if you can't get a pinion off with a "pinion puller" then you're sol.

pinion puller will work, but the ghetto way will work as well. if the pinion will be screwed, but get a well mounted vice, slam it down on the pinion, get an awl, or some type of pointed metal object that is small than the motor shaft. Use a hammer to tap the motor out of the pinion. most likely their is a bur, or defect on the shaft that caused it, so the motor shaft might be messed up, give it a nice rub down with med-fine grit sand paper

Before you try that, I recommend taking a soldering iron and press it against the pinion for about a minute. (It shouldn't melt...). It should make the pinion expand just a tad enough for your effort to pay off. It happened to me once.

cut the pinion with a dremmel. once you have a cut if it does not fall off stick a screwdriver in the cut and pry.

i actually ended up doing a combo of two of yalls tips. i heated it with my soldering iron and then used a "pinion puller"(aka drop forger. aka flywheel puller) and it came off smooth and easy. thanks guys
