Clutch bite almost at floor

HI,

Re: dispatch 2004 1.9D

I've started to find engaging first gear quite hard esp. when cold.  with the clutch to the floor i can gently grind the reverse gears together which proves (to my mind) the gearbox input shaft is not 100% free running, but still getting a bit of drive from the engine. The biting point is very close to the floor.

I've been told these are  hydraulic clutches and therefore not adjustable

Any thoughts or experience on this issue would be most welcome!

Re: Clutch bite almost at floor

Before wasting good cash on a new clutch kit when was the fluid last changed? I changed the brake and clutch fluid in my convoy as it was black and had water in it. The difference was staggering. If you have no history then i would try that first. Unsure where you bled the clutch fluid but i would look at the slave cylinder first.

Re: Clutch bite almost at floor

My gearbox is smooth as any apart from getting reverse from standstill.  I have to partialy release and re engage the cluch and all is ok.  It can be easier just snicking into reverse while just as it's rolling to a standstill on mine.  But from stationary, it needs caressing in.

Another cluch problem I had was when the pedal would randomly loose all tension and go right to the floor without pulling at all on the cluch.  As if the cable had snapped.  Turned out to be the self adjusting mechanism on the cable was letting go.

btw... anyone else find the angle of the cluch pedal a bit awkward?  I feel like I am pushing forwad almost as much as down on mine.  I have to be careful with muddy boots or my foot can slip right off the front edge of the pedle.  Can be very unerving.  Might be due to my seat position and the extra height from swivels.  Although it is quite far forward and the height should mean I am pushing down more.

Re: Clutch bite almost at floor

my 2005 van has hydraulic clutch our 306 with a DW8 (van has DW8B) is Cable............

Looking down in area of air filter box on front of G/box (Nearest front panel) you should see slave cylinder and IIRC there is a bleed nipple visible on it Also............

Renewing the fluid is an excellent idea!    I can clearly see the bleed nipple on the gearbox, but am struggling to find and identify the slave cylinder (no idea what it would look like
) a little help would be good!

Question1: Does this circuit share the brake fluid reservoir ?
Question2: Purge technique?  OPen nipple, depress clutch, close nipple - ie, same as a brake system?


Thanks

Re: Clutch bite almost at floor

Bleeding may help , but all sounds like the clutch is nearly worn out.  As the clutch wears usually the pedal pressure increases and the clutch releases right at the full extent of pedal travel .

I did wonder if it was a sign of clutch wear... My brains logic made me think the biting point would get nearer the top until finally slipping.

I will still try bleeding system - it won't take long and I don't have anything to loose!

Re: Clutch bite almost at floor

Mine is a 1998 Mk 1 van, and I have just had clutch number 3 fitted for the same reason, ie clutch bite almost at floor.

The test is can you engage gears relatively easily when the engine is stopped? Is it more difficult when the engine is running?

If the answers are both “YES”, then it is likely the pressure plate has reached the end of it’s life. OK, mine is a mechanical linkage, but when the first clutch caused the problem, I got the selector cables replaced. That worked for a couple of weeks, then it got really bad. I had to stop the engine, select gear, then start the engine. Interesting as you can imagine. Had the clutch replaced and all was fine until recently, when the same symptoms appeared. So I anticipated the failure, and had it changed. It’s like a new van now. As it has done 275,000 miles, I think nearly 140k per clutch is a reasonable life. It’s a case of bite the bullet I think. My outlook is if it works it is a useful tool for doing the job, if it doesn’t it’s a heap of junk. OK, the clutch costs more than the van is worth according to the insurers, but spending £2000 a year to keep it running is £40 a week, which is not bad, and up to now I am way under this. Additional benefit, it isn’t one of the fancy electronic thingys, so it mostly works, and is easy to fix when it stops.
