Hey guys. Attempting to remove my driver's side CV axle for a transmission rebuild but the stupid thing WILL NOT move out. It spins freely but just won't pop and slide out. I've already bent one prybar. Thoughts?

Sounds like your issue could be more then input shaft bearings.

If like to hear what the experts have to say on this as I have a similar issue on a tranny with an LSD.

Could be a fubarred clip or damaged differential spline (s) but that's just a guess.

The Drivers Side is the hardest one to remove. I have always had to use two pry bars to get the DS axle out. I have used an old set of truck T-bars cut down to make a pry bar. 

Try removing the flywheel/clutch inspection cover. This should give more area to pry against.

Got the axle out with a better prybar and a bigger hammer... kinda surprised it moved. Tranny came out with a bit (read: shit ton) of the dowels sticking and binding, got it on the ground eventually though. There's definitely some axial play on the input shaft, but the diff moves freely. It's nice to see things might not be screwed up TOO badly for once.

 

Any advice for a first timer ripping open his tranny?

Yes.  Don't fuck it up.

 

What are you doing?  Changing the syncros?  

 

My tip is to stack your gears upside down as they come off on a clean flat surface.  Totally common sense, but that's pretty much it.  Take a gear off, flip it over and stack on top of whatever you took off prior.  Then go in reverse when reassembling.  Take pics from different angles before you tear into it to make sure that forks and everything are in the right place when you put it back together.  

Replacing every bearing I can get to. Input shaft bearing failed immediately following a ton of new hardware (brake booster, poly trans mount, brake lines, master cylinder, poly shifter bushings, valve adjustment, valve cover gaskets, oil change). I've been rebuilding moped transmissions and engines for years, so hopefully this isn't any more difficult, just a larger volume of work with more moving parts. Hopefully. We'll see how it goes; I plan on performing surgery tomorrow afternoon. Will definitely do the stacking, seems like it'd remove a lot of remembering and potential guess work.

If it's only bearings you don't have to do anything to the shaft and gears after lifting them out of the casing. 

 

I've found that if the countershaft has a nut holding the bearing on (I haven't done an ew box for ages) you can get the nut off before removing the shafts by using a screwdriver to lock the gears between the shafts and a breaker bar on the nut.  Easier than doing it with the shaft on the bench.

Got it all open and apart. All bearings/seals out but that stupid countershaft needle bearing. The thing is seated in a blind hole, no easy way to get it out (without some expensive tool) that I know of. Maybe there's some really awesome simple way to get it out that everyone has been using for forever? 'Bout to try heating and beating.

On blind hole bushing or bearing removal I fill hole with thick grease or vaseline and use the shaft that goes into it (or equivalent) to drive it out. The grease acts like a hydraulic fluid to press out from within.

Got it out with a pilot bearing puller from Advanced. The pullers teeth WOULD have been just a bit too thick, but the previous renter kinda abused them and shaved some material off, allowing the teeth to justttt barely get underneath a couple of needles. Just powerwashed all the case pieces, knocked all the seals out, and polished the mating surfaces. I have not yet removed/replaced the countershaft bearing, it seems to be fine and I have no press available to re-seat fifth gear squarely. Is the countershaft bearing something that fails commonly/should be swapped, regardless of how "fine" it feels? Also, diff bearing removal. Ideas?

 

 

P.S. thanks a bunch for the help so far guys, couldn't do it without you.

Got it all back together. In moving it off the bench I noticed there's a bit of play in the stuff inside, makes for a slight noise when moving the tranny around. Is this normal or did I screw somehting up?
