a question about the clutch release arm

[theiceman]

ok so what am I missing ? either mentally or mechanically .

on the adjustment you are looking for 1.2mm between the lever arm and the clutch release arm. But what creates to stop or " resting" position of the lever arm. yes my omega spring was binding on the H/E so I had to make some adjustment to it , but the more adjustment I made the further and further back the spring would go . to contact it again and the further back the lever arm would go . Do I likely have an issue inside my clutch ? the car seems to be operating flawlessly, I eventually gave up, just put the cable on and cranked it to 1mm . throw is fine and I get the full 1 inch throw. it just bugs me that it doesn't seem right or I don't understand where that arm is supposed to stop.

so gents what am I missing ? just keep banging the exchanger ?

hi..this is your stop for the clutch arm on the trany.It has to be in right angle not open

ahhhhhh

Thank you , I think this may be the answer I am looking for. I will crawl under and have a look

Do you have a part number on that spring?

just noticed mine is broke.

[proporsche]

Hi..do you mean omega spring?
915 116 064 01

the L shape bracket has no part number i believe...

[WJL911]

yes thanks. Computers need me to ask exactly the right term, tried Omega nothing came up.

okay I MAY have found my issue. what part of the spring is supposed to hit that block ? on mine I think it may be slipping under or not catching the right part of the spring. I think it is hitting the the very tip of the small shaft that goes through the arm and the spring. its really difficult to see. The only way to know for sure is to take the exchangers off and see if it flies by.
the screws on that block are in real tight and I don't want to risk stripping them to tak eit off and make a new one

[theiceman]

okay I established the omega spring is going under the stop block piece

there is too much up and down play in the cross shaft to start off with id say 2-3mm that just cant be right as it allows the spring under the stop bracket and it hits the exchanger. that's the first problem.

if I force it back and tap it up it will stay temporarily. Is that all I need to do while I make my initial adjustment? because once I adjust to 1 mm that wont matter anyway and would never ever even go back there.

secondly the smaller lever that is splined to the shaft. when that goes to home and is pulled back by the small spring do I just adjust to that , I can take and push it further one full mm or so. I just had my engine out last year and the shaft really flopped around, not seized at all. if I push it back manually and set to 1mm as soon as I press the clutch and let go my gap is gone.

last question bentley says both levers are splined to the cross shaft I think its called. this is impossible as you pull one to contact the other so they cant both be splined, they would move together. should the bigger shaft move freely and independent of the smaller one with ease ? if I take the spring off should I be able to move it back and forth while holding the splined shaft with the smaller lever ?

thanks

what is exactly your problem???Yes the little bracket is a stop for the shaft on the omega spring.
Also do you have a stop on your floor board??That is there to stop the pedal so you do not put too much pressure on the TO bearing on the clutch pressure plate.

[theiceman]

Yes I set the floor board for exactly 25.4mm of play. My problem is when I set the 1mm gap and activate the clutch pedal and release my 1mm gap is gone. So im trying to set the gap properly.
Bowden tube is seated properly also.
But 1mm gap will come back lf I push small lever back by hand.

I am also trying to understand the system and how it works. My cross shaft is certainly not seized in the transmission housing, but if the clutch arm ( the long one with the omega spring), is supposed to move freely on the cross shaft, that may be seizing and not letting the small arm retract as the big omega spring will pull the large lever back and if its seizing to the cross shaft drag the small arm with it.

I hope I have explained myself correctly

i think at this point take a picture of the arm how do you have it installed i need to see it...

I had a similar issue with the long arm, the one the cable attaches to, being rusted to the shaft. see video. I had to remove the gearbox and soak it in oil in order to free it up and remove it.

[theiceman]

I cant get a good pic until I jack it up again later but it is all installed correctly.
I think I have established the clutch arm is seizing on the cross shaft. there is no rubber seal anymore between the cutch arm and housing on the cross shaft. \the next question is how do I get the clutch arm off for cleaning and lubing Is it held on with a roll pin or is that some sort of bolt ?

perhaps I might even be able to squirt some penetrating fluid at the gap where the seal used to be and let it run down inside. if I can free it up I will definitely be able to see if it is my route cause.

is that you simon

I wanted to ask you what is holding the clutch arm in place ? mine is not seized as bad as yours I don't think as I get some movement. is it a roll pin or some type of bolt ?

if I can get that out I might be able to devise a puller.

if I can pull it off it may save me pulling the whole thing out of the car

Thanks

[proporsche]

ok..if i understand correctly..have you ever remove the clutch arm(with the omega spring) from your shaft?
In your case there is a pin across the shaft half way up the shaft.Maybe you do not have it there anymore?You need to remove the pin.If it is frozen use a lot of wd40 and impact hammer .Put a big bar between the arm and the trany and while you are using the impact hammer it will slide down eventually..
First try punch and hammer but i doubt it will help

I think Ivan we are on the same page now. no I have never removed the arm from the shaft. that's what I want to do now as I think that's the problem. I see the pin but I wasn't sure if it was a pin or broken off bolt . oh its still there.. must drive that out first

Then I will try and remove arm

Thanks very much Ivan . I will report back.

[theiceman]

my theory is when the omega spring pulls the clutch assist lever back when you release the cutch. the clutch assist arm is seizing to the cross shaft so it turns the cross shaft and brings the smaller clutch actuator arm with it. overriding the small spring on that arm. that's why I have no gap after release, and I can push the small arm back into position ( as its not totally seized.
I think the stop bracket on the assist arm is an issue for another day.

[proporsche]

Just one thing..do not put the pin back, it has no use..Just lubricate the shaft with a lot of Bosch grease or Sachs grease nowadays...also do not forget to get those seals for up on the arm and between the arm and the little finger

Are you loading up the spring?
