Type 2 transmission input shaft play

So I am thinking that this is way to much shaft play for the input shaft. But a second opinion is always a good thing. So is a new front bearing in order? just want to make sure before i tear into it. Thanks guys.

Ummm.... that's usually called the input shaft and play like that is normal when the engine isn't in place to support the other end of the shaft. What's it like for in/out freeplay?

That's perfectly normal. The shaft end doesn't hang in midair like that
when it's installed, so the play you see is irrelevant. There is no bearing
where the shaft emerges from the clutch housing.

When the engine and tranny are mated, the end of the shaft is supported by the pilot bearing. Pilot bearings have a relatively short life and will damage the shaft when they fail, be sure to replace yours while you have access.

I don't think that's normal.

My bus is an engine swap with an 091. We had some strange noises in my rebuilt trans, which, after investigation, were found to be due to the the front mainshaft bearing in the case being badly worn and allowing radial play.

When the transaxle was out, there was some in-out play on the input shaft - much less than your video. This was a clue to the trans builder that something wasn't right. After re-rebuilding, there was hardly any in-out play.

On mine, the front mainshaft bearing was replaced as well as the input shaft and the inputshaft-mainshaft joiner piece. All this was done "just in case" due to all of the cost of taking things apart.

kreemowest is right that there is no bearing holding that end up. Still, my suggestion before you put it all back together is at least to ask a transmission pro for their opinion.

Good luck!

i just had my hands all up in one of these...

if you have lots on in/out play (axial play) you may be in trouble. the wobbly shaft is due to its design. you would be hard pressed to tell bearing condition unless you pull the bell housing

VW's 2-piece "quill shaft" design is absolutely brilliant. But the "feel" often confuses a newbie.

If there is no slop, this is a clue that someone without a manual installed the input shaft incorrectly, believing that "rigid" = good.

In & out movement would suggest that the mainshaft's front ball bearing isn't securely held within the case. This is quite common in old, worn out transaxles.

Here's an item to feed the paranoia: it has been (rarely) reported that the input shaft securing stud can sometimes screw itself all the way
into/out of the input/main shaft, thus causing separation of the two shaft segments. One supposes that at some stage of this process, there will
be excessive input shaft "wobble" present. The solution is to remove the clutch housing and inspect, perhaps replacing the original 7 mm stud with
one having a non-continuous thread, or just a longer one.

Unscrew that shaft and take a look at the other end.

I have just looked at that video clip again. The first time I guess I didn't let it go all the way to the end and missed the shaft getting moved pretty damn
far to the right, which seems very abnormal. Time to open it up and have a look.

Here's a relevant thread: http://www.thesamba.com/vw/forum/viewtopic.php?t=557933.

I have an 091 that the input shaft can be pulled out 4 inches or so, completely seperated from the mainshaft. you can slide it back in and mate them back together solid and everything turns all right. what do I need to do so that the input shaft isnt loose like that?

Drain the tranny and remove the bellhousing and tell us what you find in there. The problem should be fairly obvious once you can see how everything attaches.

Yes some play is normal but the play you are experiencing is a little excessive. The problem may not be entirely with the input shaft though. (if at all.) One little thing that everyone seemed to miss but was glaringly apparent to me on your video.

The oil slinger / input shaft support in the bell housing itself is loose and being moved around along with the input shaft when you checked it. that oil slinger is a tolerance press fit then it is also swedged for good measure. In most cases it may not be something fixable, you will most likely need to replace the bell housing. Take a closer look at your vid you will see what I mean. Otherwise you will get a good look at what I am talking about when you remove the bell housing.
