Hey Georg,

Great work. I have had only one ring break like yours, and that was recently. I use a hammer to beat the dog teeth off. I will check my bearing collection and see if I have what you need. I definitely have the R/P, I do not have the nuts as I use new stainless ones in my rebuilds. PM me your contact and shipping info and I will get you a price quote for what I have.

[Dr Evil]

Did you need the smaller bearing that goes above the larger one in the case as well?

Georg,

As Mike mentioned above, sometimes the ring section breaks off the syncho hub like yours did. Sometimes the hubs seem to be pressed onto the gear extremely tight (as if they have been welded, or as if someone used loctite).

When you use that tool you can either pound it off using a hammer or use a press. I like using the press (as you showed in your photo). However, I have a suspicion (can't say for sure) that for the ones that are on extremely tight, they are more likely to break if you use a press. I suspect that the hammer approach may help break something free without causing a stress fracture along the ring if you just keep applying pressure via a press. While I use the press on a regular basis, if I have one that is stubborn, I remove it from the press, give it a few hits with the hammer and then put it back on the press and give it a second try. I haven't done it enough to determine if this is helping or not as the vast majority of them pop off without requiring lots of pressure on the press.

If they the hub breaks, just grind a notch in like you did and the then it should split and come off. It's a pain, and takes a bit of work, but if you are careful it does no damage to the gear.

I continued my work with cleaning some parts of the transmission. Blasting oft parts which are later will be zink plated and case parst







I use WD40 to stop corusion of the magnesium case. If all is done and the case is closed after the rebuild I will use wax for that.

If I have the nissing Parts I will teardown the two shafts. I like to replace all syncros with new ones.

I will go out and measure the bearing right now. I had to get a battery for my caliper (IMG:style_emoticons/default/wink.gif)

I'll PM you, too.

[914Gelb]

That's fine, If I have all parts I will finish my work. I have to beat blast the case too.
This is still open. And the new syncors are still not deivered.

[914Gelb]

I have to leave for today, I will anwser your mail. My address you should already received.

Thanks in advance! (IMG:style_emoticons/default/beerchug.gif)

more pictures from my transmission rebuild. I made a contact pattern of the ring and pinion, the pattern is just made with hand load. The measured backlash is 0.16mm. I always put the dye on the ring. I gues the R&P is a Gleason style and not Klingenberg.. hope so.




What is your opinion about this contact pattern, can I go with this?
This is my first setting, I made a scound one, see next post

Georg

[914Gelb]

2nd option of S&P setting.





Pls. tell me your knowledge.

I bought the tool (VW 385)to measure the pinion depth. These tools are made by MATRA a German company. In addition I like to show the result of my transmission rebuild.

That is a beautiful transaxle you have there. Congratulations on your rebuild.

[rjames]

wow. Nicely done!

[Dr Evil]

Good job, Georg (IMG:style_emoticons/default/thumb3d.gif) What was the price for the tool? I have a similar one that does the same thing that was being sold for $400.

[914Gelb]

Hello,

the price was match more than 400. The tool is completely new, it's the configuration which is described in the transmission manual:

1 x VAG VW 385 /17, Messplatte d=50 mm 100.07EUR
1 x VAG VW 385 /15, Messuhrverlängerung 9,3 mm 13.06EUR
1 x VAG VW 385 /30, Universaleinstellmeister 490.61EUR
1 x VAG VW 385 /14, Meßstößel 30 mm 29.86EUR
1 x VAG VW 385 /4, Zentrierscheibe (2 Stück) 397.73EUR
1 x VAG VW 385 /1, Messdorn 827.68EUR

It' s a big investigation but I tried to work with dye.. contact pattern..not good, needs much time.
Just two service stations in Austria are up to the task to set the backlash and pinion depth. For the job they are asking 400 up to 1000€.

I have as second transmission I like to rebuild from my 2.0 liter 914.

An additional reason, the VW tools which start with number 3 will just produced until 2014. Afterwards these tools are not longer purchasable!!

I also like to do the job for other 914 and maybe 911 drivers.

Can you show your tool, where does it come from?




Ciao

Georg

....oh no....he wants to see the Doc's tool...... watch out....

[Dr Evil]

My tool is made out of an old differential and was sold on ebay. I will try to post a pic of it.

The time and cost it takes to set the R/P often exceeds the cost of just buying another core transmission here in the USA. Buying another core generally has the side effect of having extra parts and cutting the parts cost down in the end. As such, I have not had to use my R/P tool yet.
