Got the tranny out of the car today. Pretty proud of that moment since my friend James took the motor and transmission out last time. I had to do it on my own this time. Fairly simple actually, since the tranny is all that is in there now. Just remove the wheel hubs from the struts and the steering control rods and then knock the half shafts out of the hubs. Take a screw driver and a hammer and give a whack to the CV joints connected to the tranny and there you have most of the work done. Climb under and undo one bolt and knock a pin out of the stick shift control arms and you are almost there. Then put a jack under the transmission and undo the bolts connecting it to the rubber mounts and lower it down. Thats it. I didn't take any photos of that journey, but coming next is the reason I got it out of the car. Broken Input Shaft Bearing.

| Before... |
 |
| Removed the cover to the 5th gear section |
 |
| Close up of 5th gear bearing, selector arm and countershaft |
 |
| 5th gear bearing, arm, synchro and gear removed |
 |
| Keeping track of the order pieces are removed |
 |
| Remove bolts, springs and ball bearings from gear shift shafts |
 |
| Main case removed - Differential on left, Main and countershafts on right |
 |
| Over the top |
 |
| Game of Thrones shot |
 |
| Reverse is removed |
 |
| My Neighbor, Paco, removing some bolts |
 |
| Main Shaft and Counter Shaft removed - See broken bearing on upper right |
 |
| Center of broken bearing removed - Real pain to get outer bearing case removed when it is broken |
 |
| Shafts on the table - Notice bits of metal on cardboard - broken bearings that came out of tranny |
 |
| Here is the outer bearing case stuck in its home - Paco saved the day and got it out |
 |
| Put in new Input Shaft Bearing and started reassembly |
 |
| Another Game of Thrones shot - Winterfell rising from the Flames |
 |
| The work table |
 |
| All re-assembled - Number 5 is alive |
 |
| Spin the shaft and magically, no clicky clicky sound and the shaft doesn't wiggle about |
So, theres it is. What a day. So glad we got it all back together and it appears it should be good to go now. Next weekend I will get some Transmission fluid in it and mate it to the motor. Then give it a low voltage test and see how it sounds. If all goes well, then it will go back into the car for some more testing. Pretty pumped about everything I learned today and how smoothly it went.
Haha, Game of Thrones..
ReplyDeleteAll those gears, ball bearings and springs scare me.
I suspect you're going to continue to have transmission/motor shaft problems. The alignment of the two needs to be within a couple of thousands of an inch or less. This is difficult to do just by feel. The pilot bearing extension on the trans. input shaft(which looks like was cut off?) ,on this type of trans., could be used to align the two. A close, sliding fit hole would have to be machined in the coupler to fit the extension.
ReplyDeleteAlso,the trans. and motor should be assembled with everything pulled out of the car and the shafts vertical. This would prevent the weight of the motor from preloading the trans. bearings. Also, as you unfortunately found out, the two shafts must not bottom out.
I know this seems like a PITA, but it's what's needed to get the proper alignment. Once the set up is aligned and test run-no noise or broken parts over a good test period, dowel pins(like the OEM) can be installed in the adapter plate to maintain the alignment when things are taken apart and put back together.
BTW, this alignment technique wont work with most front engine/rear wheel drive cars. The trans. input shaft doesn't have enough bearing support inside the trans.
