The clutch disk can rust to the splines of the input shaft, making installation/ removal difficult.
The input shaft is supported by the pilot bearing in the gland nut. When the engine is removed there will be a scary amount of movement side to side/ up and down. Perfectly normal. |

That's not normal. You've probably sheared the 7mm stud that aligns the input shaft with the main shaft.
Remove the trans and remove the drive cup/flange and cover on the starter side of the trans. There is a coupler and a circlip there that will also need reinstall.
Good luck |

If it is a broken stud, it's because whoever installed it tightened it up to "feel solid". IMHO, backing off only a spline or two is not enough. Engine weight can snap the stud if the shafts leverage against one another. Our company has sold hundreds of custom Porsche racing mainshafts using the same 7mm stud and we've never broken one. That's because we tell the installer to back off a full quarter turn and let it feel sloppy. VW's newer replacement stud is better, as it has a centering feature.

That's most likely not going to work for him if he has a 73 ssc trans. He'll have to pull both drive cups the left side cover and diff to get to the input shaft.

As they've said you've probably sheared the stud holding the input shaft to the mainshaft. You'll need to get inside the trans to fix it. That'll tell you the cause, most likely the circlip came off or broke allowing the reverse gear to walk off the splines between the input shaft and mainshaft. Fortunately it's just under the side cover so you only have to pull the diff out, you don't have to mess with the gear stack.
Pics of how the input shaft is connected to the main shaft using the reverse gear to hold the splines together: http://www.thesamba.com/vw/forum/viewtopic.php?p=5717907#5717907 |

Are you wanting to use it for parts to fix the original or were you just going to swap the entire transmission.
If swapping the whole thing, it looks to be an AH code box (the number stamped below the VW symbol in your last pic) which has slightly different gear ratios, but you probably won't notice much difference. One problem is that the second trans has an early style throwout bearing, but your original has the late style. There are 2 ways to fix that but the simplest is to install an early style clutch pressure plate with a centering ring (if you don't have one around). See the differences here: http://www.thesamba.com/vw/forum/viewtopic.php?p=5298554#5298554 Second problem is I don't think the transmission mounts are the same and I don't know the specifics on what it would take to get the second box to mount in the car. Though since you have the rear cradle for the second transmission, I think you can either weld on a new front mount on the chassis to fit the second trans' mount or you can swap the original nose cone onto the second transmission to fit the original chassis mount. Second option's easier.
Personally, I'd try to fix the original box as it's stronger overall. |
