To much bend in the Bowden tube?

streetbuggy8804 · Posted: Thu Jan 24, 2013 8:54 am Post subject: To much bend in the Bowden tube?

Is it possible to have too much bend in the Bowden tube? Got the shorter from CMA and installed it. Have pressure but tried to adjust out the clutch last night while the motor was running. It's currently at the point where the clutch lever arm in no longer straight up and down but it is still not disengaging. I'm thinking the Bowden tube has a large degree of bend in it. Could this at least be part of my problem?

I will have to take some pics of the bowden tube. The difference now is that I went from a bug tranny to a bus tranny to accommodate my ej25. I'm thinking that maybe there is a shorter Bowden tube used for a bus tranny. The bend to me look a little extreme. I have enough adjustment in the cma shortner deal to be alright though. At least I think so.

Thinking that the bow is suppsed to be around 1/2". I had an issue with the current prioject where the bowden tube didnt fit through the retainer at the tranny far enough (couldnt even get the boot on). Cable seemed too short and the clutch efforts was high. Replaced the tube and all is right with the world. Something that you probably already know, but I didnt until a few months ago was to have the cable inside the tube before you install it to prevent kinking the tube.

well I am hoping that is the fix as that is a simple one. Here is a pic of the adjuster (I have this one on hand). I know the pic is kind of cocked, but you can see that the arm is not in a verticle position and still not engaging.

I don't see a bowden tube. Am I missing something?

Yeah that's what I said in my earlier post. I don't have a boden tube pic on hand. All I had was the clutch cable to pic which shows the semi moved position of the clutch. Bowden tube pic will be taken tonight when I get home from work.

I'm not sure what you have there but it doesn't look right.
Here is What a bowden tube should look like.

Seems to be a lot of "skimmers" here. That is not a pic of my Bowden tube. It's a pic showing the position of my clutch lever. The stain steel braided line is my throttle cable guide tube.

Engine turns. I push clutch in. Can not put in gear. Motor is not running. No problem putting in gear. Clutch lever at tranny is already adjusted to the point that it is not completely vertice when clutch is not depressed (pic.). Do not currently have a pic of the Bowden tub but the bend it more than what looks normal. I will try and mess with the Bowden tube tonight.

Doesn't sound like a Bowden tube problem. If the clutch isn't disengaging when you pull back the lever, you might have the wrong throwout bearing for your pressure plate, or your throwout bearing may have come off the throwout fork.

Your clutch guide tube may have also broke free in the tunnel. If its not securely mounted, it wil just flex around and not disengage the clutch.

No I can shift into gear with engine off and clutch depressed. Once engine runs and clutch pedal is depressed I can not shift into gear. In addition if I am trying to shift into first for example and I'm pressing the shifter twords that gear, with the clutch pedal depressed ( and engine running), the car starts to creep forward as if it was in gear and I was riding the point between letting off the clutch and pushing on the gas. Hope this makes sense. Clearly the clutch is not fully disengaging the spinning motor. Also just to clarify. I am clearly ( by feel) not in the gear.

What year 3 rib trans did you install? Did you do anything to the input shaft on the 3 rib?

OK - So starting at the top. How much free play in your clutch pedal before you start to feel resistance? How far from the firewall is the top of the clutch pedal?

You can have your pedal set up so there is not enough travel. You can also have too long (or a stretched) clutch cable if you cant adjust it far enough.

Is this new or you are just getting things put together. Its important to get this right - obviously you dont want to be grinding gears, but also you dont want to kill your throwout bearing.

Another thing to check is that the clutch disk can move fully in and out freely on the splines of the trans input shaft. If it binds it can prevent the clutch from releasing. http://www.thesamba.com/vw/forum/viewtopic.php?t=476770

Or the pilot bearing in the gland nut hasn't been lubed properly and siezed up making the input shaft turn regardless of what you do with the clutch.

Could also be from someone putting on a clutch release arm that is too long.

That is not a VW engine. What adapter plate, pressure plate and clutch disc are you running? Did you buy it all together in a kit form or piece it together?

You simply may be so far apart on the TO Bearing and the pressure plate that it is not depressing the pressure plate enough to free the disc.
