I know this isn't a bus but close enough lol I bought this truck 50k miles with starter problems but I just about narrowed it down to flywheel or flex plate bad it has a allison behind it so my question is how bad is it to replace the flywheel without pulling it all the way out I'm a decent mechanic but haven't worked on any medium duty truck also can someone tell me what tooth bendix is supposed to be on the starter and what tooth flywheel is supposed to be on it I'm trying to do this in the parking lot I bought the truck in to refrain from spending 400 bucks on a tow bill thanks for the input
