    @CrispysProjects i went (ok, read was forced to) one step ahead with this complete tear down by having to reseat the pole pieces,the permanent magnets around the rotor. Thats a bit of a pain in the you know where by itself and that pain doubles when you realise that the rotor now turns in reverse and slips the one way sprag clutch. Had to tear it down again, but in the end, it was worth it. Have a video, might post it. Loved your vid, mine is exactly the same unit. Good job!

    Couple of minor points - It's a good idea the clean the commutator back to clean copper with some emery paper, and clean out the channels between the bars of the commutator with a thin pick. You can even put the armature in a drill to do it. And they're brushes not bushes :) Last one - still sounds a but lazy, maybe think about replacing the brushes anyway as they're not expensive.

    I use a bit of angle iron with 4 holes drilled into it lining up with the solenoid screws and plunger to press it out in a vice. I used to work in a factory with a press to split them. I used to do about 140 a shift. Bosch 0331 lol.

    This has been the only starter strip down video that I've seen that mentions the locating nub on the starter barrel. After I figured it out. After about 2 hours of frustration and tears. In other videos they just slap it together and it all fits. I wish I'd come here first.

    Hey, Chad I've not come across many that don't turn by had unless there has been compete failure of something, take it you've gone back partly stripped it to check it out what's stuck and then parts available. Might be an option to find a rebuilt one on an exchange basis (normally cheaper than outright buying) or finding used unit These carry massive current, jamming on could cause massive heat which in is never good near fuel and other plastics Sorry, better stay safe 👍

    I've not came across that before, to turn the opposite way would been the earth and lives swapped around which isn't easy. More likely is something isn't right maybe with the throw out arm. strip down again and recheck everything and all the electrical, including the 13mm nuts are clean - good luck and recheck everything many times
