Ok, found an issue with the Medusa motors! The shafts on the 3.17mm motor are a wee bit too big, so when I put this one pinion on, it's a snug fit, all well and good, but when it comes time to take it off...it will NOT come off.
I've tried everything from heating the pinion up, to trying to break it loose by twisting the gear one way and the shaft the other, to simply just grabbing the pinion with a freakin' set of pliers and trying to rip the damn thing off. NOTHING!
I need a pinion puller is what it comes down to. So after this gear comes off (not if, but when), I need to sand the shaft down a tad so it doesn't crap out on me again like this.







Edit: Nevermind, I just dremeled the shit out of the pinion, sanded the shaft down (it looks like hell), and now have to go to the LHS to get another 25 tooth pinion. All of this just so I could remount the damn thing to the FLM tranny case, which was not fun at all...
