You people are overthingking this. I have never had one fall out of the groove.


Because it hasn’t happened to you therefore it’s not a problem?
Fact is it does happen, I’ve seen it more than once and VW quietly changed the design.

I’ve broken a throw out bearing shaft with a 2300lb pressure plate. I’m sure the arm was worn. Never had a clip fall out under normal circumstance.

I don't like the Empi style throw out bearings on the early (or late), but especially the early as they have shallow pockets for the clips. If you get a Sachs throw out bearing it has the plastic insert that the clip sits in, but the clips sit in there all the way.

Empi or anyone selling the metal lugs on the side I'd say away from as it doesn't leave any install room for that leg of the clip.

I think it's a bit of a placebo, but if that's what he needs to be able to sleep at night , so be it.

I'm pretty sure we all have one bit of our car that was modified strictly out of fear...or a bad previous experience. Different folks, different phobias...

And I have seen one fail, it's usually because the arm is very worn where the bearing rests, esp. if it's just one side... but you would have spotted that. I've also seen well-maintained stuff that was still running on it's original graphite T.O. bearing. So grease that surface!!! (copper is good for heat).

The reason the early style clips started falling out is because the saddles the TO bearing rides in are worn out from 70 years of use. Add to that some shitty built Chinese junk and spring steel clips that aren't that springy and it is what it is. I don't know if I have ever seen a loopy one fail if properly installed.

The later model TO bearings and diaphragm clutch plates were a game changer.

I have a 67 trans with the early "U" shaped clips , are the clips that have a closed loop better or safer? Do they even work on early split trans or should I stay with factory U shaped clips?
I have the trans out and have and have a chance to put new clips in since these are probably original.
Thoughts?

As Volkswagen spent more time and effort coming up with the irs trans in 68-69( sooner than the late tob) you are also saying that all swing cars are junk and you would never work on one? VW used the early design tob for more than 30 years with no real problems, that is a fact, didn't mean to create an arguement just to state facts, not oppinions

The only way your claim can be true is if you've kept in contact with all those thousands of gearbox buyers over their car's whole lifetime. If the clips fell off a TO bearing on one of your gearboxes 5 years after you built it, why would the owner bother to call you up and whine about it? They'll just fix it and get on with life.

There must've been a reason VW went to all the trouble to do the redesign if the original design was so reliable.

And yet they do fall off.

Dale M., just to cover it in a Bug you are suppost to have 1/2" to 1" of Pedal movement with your clutch pedal before ingagement? Been a while since I have seen the book on this, but this approach impliments what you are getting at.... Just making sure my measurement is not off.... RB


My Haynes manual states 1/2 to 3/4 inch .... But then again when you think of length of clutch pedal and all the ratios involved (hook at pedal pivot and length of arm(s) in trans axle), if TB drops off pins, you can not be within adjustment tolerances because movement at actual TB is probably about 1/16- 3/32 at MOST (to contact) when free play is correct... The concept is to keep TB really close to, but not touching clutch cover springs (or ring) when not depressed...

I have been driving and racing VW's since 1972 and I have never had a TO bearing clip fall off. I never used safety wire on them.

Unneeded as far as I can see.

The TO bearing falls off and lands on the input shaft. Then when you push the clutch pedal, it doesn't work right. Usually some parts are damaged in the process.

Unneeded for you now, but wait until it happens to you. Spending 5 min with some wire is certainly less work than pulling your engine when it happens. Stick around this board for a while, it happens much more than you think. It is part of the reason I NEVER use the early crappy type TO bearing.

I've had this happen. My bearing came off of one of the forks which rendered the clutch ineffective (and ruined the bearing). The pedal feel was such that I thought I'd broken the cable.

The clip got wedged behind the flat clutch springs, requiring me to construct a lever apparatus to compress the clutch while I fished out the clip with a magnet-on-a-stick.

I would have drilled the holes lower on the arms. You want to hold the clips in, not up.
