Re: syncro gearbox swop drh to dda;now clutch prob !!!

has anyone done this or know if it fits ok?

thanks for any info
i got this g.box swopped and its a good box
only difference is an arm to lift a rod to enable reverse from other linkage

but i now have a problem with the van creeping forward a little when stationary in gear.
also not easy to select gears when van is running,bit ok with ignition off.
clutch was checked when gearbox changed and was good
release bearing was also swopped from original box,clutch was fine when this box was in it.
have bled it a few times

can any one suggest what this could be?
or am i doing something wrong bleeding it from below?

cheers pete

What condition is the "release fork or arm" in? Sorry, don`t have the ETKA Term at the mo

The way I read U`r post it sounds like despite U pressing down the clutch the car howes forward, correct? What U are suggestion is that the clutch does not disengage? Correct?
It amazes me that U did not replace release bearing with a new one:(
Was the gbox oil replaced?

yes to the 1st 2,

i didnt do the swop
a gearbox specialist did
they put in the original release bearing and inspected the clutch
and renewed oil in g.box and transfer case.

the clutch was fine before the swop
so they just used the old bearing

i would bleed the clutch hydralic system TBH
In all honesty I would expect a spezialist being contracted with the work to do that. AFAIK it has been bled
System was fine before the box was replaced?:*
I am asking here
Could there be a different "stroke" (lenght) IF the cylinder has been replaced? I know from Audi 80 there was a loose rod that differed from box to box. Enought to cause a "hick up". What are U`r thoughts on that TONIC?T: Genuine Q :)

as an after thought
i looked at elsaweb,and it showed two stages of bleeding the system
1st higher up then lower down...
i dont know if garage bled it up high or not?
mayb there is some air still up high in lines,
i know they bled it down low from bottom of g.box as did i.

to me (from my limited experience of various vehicles, military, HGV) it sound like there is some clutch drag, hence me saying bleed the lines. Top tip for bleeding a system, start at pressure source then bleed the various points from nearest to furthest bleed nipples to the pressure source.
could be the friction plate being the wrong way round, all the friction plates i have seen have had something saying either 'face to flywheel' or something along those lines, if the wrong way round then it could move the friction plate closer to the flywheel.
What is the bite point like on the clutch?

Clearly some clutch drag, true
I would have thought the bleeding would be done by now...
Is there a loose ron on these boxes as described above`?
yes, a flipped clutch plate could cause a similar issue from what I have experienced

ok cheers,
will try again next week[have to go uk]
i would have expectd them to get it right as they are a gearbox centre only.
clutch bites a bit earlier than it used to.

thanks for replies,pete

Are the ratios not different between the two gearboxes also? so rear diff would need to match the gearbox, know of a 2.5 tdi for breaking,pm if interested
