Not Happy with Clutch Feel?
#21
No, I'm in MD. I know of Zeckhausen by reputation. He was the one that came up with the solution for the BMW clutch delay valve that lots of folks were grumbling about. Dave's been extremely willing to help on this issue with the torque peak limiter (same type of device, different name).

Now that I am wrapping up phase one of my project with VMax, it's time to focus on the clutch issue.
Buckingham, Lizzardo, and anyone else not satisfied with the grip of your MT clutch, please take the issue to your dealer and ask them to elevate it to their regional rep. This problem can be fixed, and if enough of a commotion is made, Jag may step up with a (for some, marginally satisfactory) solution like they did for the Meridian issues. If not, and like what some of the audiophiles on this forum have done, I'll have performance professionals address the problem.

2. There is also free flow in both directions between the long tube (that goes through the bell housing and connects to the throw-out cylinder) and the bleeder chamber. (both air flow and visible light).
3. There is relatively free flow towards the tube and restricted flow in the reverse direction when the bleeder opening is capped.
4. If the flow is rapidly reversed, you can hear either a flapper or valve ball flap back and forth.
5. Looking down the pressure line fitting, it looks like the valving mechanism begins within an inch of the fitting face and most like takes up some space in the elbow.
5. Construction of the part body is done in 2 longitudinal sections that are bonded together after the valving mechanism is inserted.
6. Based on the fittings, it seems the only way to remove this device is to remove the transmission to uncouple the tube from the throw-out cylinder.
I have a thought on next steps and will advise when I have further results to report.

However, I think I figured it out. I believe the valving is done with a small sliding piston that can easily be drilled through with a 1/8" drill bit. I now have a fitting with no restriction in either direction.
Now. if I can just figure out how to drill that hole while the TPC valve is in place. If I only had a dentist drill.

I got mine for about $60 delivered from the UK (www.brit-car.co.uk).

Right-angle attachments can be had, along with flexible ones. Does the drill go in through the master cylinder side or the bleed valve side?

90 DEGREE ANGLE DRILL KIT 9885 - Cleaveland Aircraft Tool
What I've found from quick searching is that this sort of thing is more common in the aircraft mechanic's world.

Amazon.com 21 bucks!
Drat, saw it was for a screwdriver bit... might keep searching...

Maybe this... for 7 bucks... Looks to be designed for wood... 3/8 inch though... and its 4 feet long....
3/8 in. x 48 in. Flex Drill Bit
1/4 inch and only 24 inches long...

This gets a little closer, but still not in your ballpark.

Here's the project at hand:
The first picture is a downward view under the back of the engine cover. There is sufficient room to get in there with a wrench to bleed the clutch hydraulic line, so it should give adequate access to the right angle drill (shown in the 2nd and 3rd picture) after the hydraulic line is disconnected. That drill will arrive on Tuesday.

I would be concerned about drilling the torque limiter in the car without
removing it. The drilling operation will bring chips or plastic crumbs to
the hydraulic system of the clutch.
Most probably the plastic material contains some fibre reinforcements so
the crumbs won't be very gentle to the slave piston fitting as well as
to the piston sealing. Because density of plastic material is higher than
the density of the hydraulic fluid of the clutch system it will go down to
the slave cylinder for sure. As a result you might get a slave cylinder leakage.
Perhaps its worth to think about an alternative how to modify the torque
limiter unit in the car. Bisectioning a sample part to see how it works in
detail might help to find a smarter solution.

Next time the transmission has to come out, I'd replace the clutch kit with a decent performance clutch in any event.
