Length comparison 915-shortnose G50

[Sandeep]

Hi Wally,

I have a question about the LUK annular TOB. The bearing has an internal spring that keeps the bearing at maximum extension. I am not sure if this changes when hooked up to hydraulic lines (my next step after machining the bellhousing shorter) but would this mean that the bearing would always be engaged to the pressure plate fingers ?

I am not sure if this spring needs to be removed as I don't have any documentation on its operation / servicing. Can you please comment ?

Thanks

Sandeep

I left the spring in and it works fine. Spring still works the same when hydr.lines are on. There's just no real pressure on the bearing from the spring. I think thios was done intentionally by Luk. Just leave things stock if can be is my feeling

Maybe i missed it, but which throw-out did you use?
Do you have the part number?

You are still using the SACO master, right?

How did the travel/pressure ratio work out using that throwout?

(Send me a bill for the consulting..)

No part number, but its a VW Passat unit from Luk. Think its from a 3B/3BG model. Sandeep uses the same one I noticed.

Yep, amazingly its still leak free and works extremely well with all the porsche trannies I used.

Apperently, it just works. I don't know by what yardstick you want me to describe/measure this?
I think I just got lucky with ratios and travel lengths and such or maybe its just not as critical as one would think

After digging around a bit, i came up with LUK part# W0133-1841866
It also fits Golfs and Eos of a similar era.

Once it comes in, i will be copying your (brilliant) idea.
I hope it works out on my 923...

By the way,
How do you bleed that sucker, anyway?
You don't have to take the motor out to bleed the clutch, do you?

I would not be too sure about that as the 915 bellhousing has less room then a G50.
I looked back then and no porsche tuner I could find including wevo iirc supplied a kit for this...

External bleeding with a T-piece where a bleed nipple is screwed in the 3rd hole

Wally - do you have the workshop manual for the G50? Just picked up a G50/01, and need to disassemble it, to shorten the bell housing.

Thanks!
