When, and only when.. reving high in 1st then changing to 2nd.. it always crunches

any reason why?


box is quaife and has just been rebuilt by bernie.. clutch is a low mileage alcon 6 paddle


any reasons casuing this?

 

you changing gear faster then the syncro?

 

Learn how to shift you c*nt!





















































No idea mate....

 

Adam,

 

no, deffo not changing too fast.. tried a slow change at high revs and still the same

almost like its not engaged the clutch properly...

 

Have you asked Bernie? Would be the 1st person i would consult!

 

My first thoughts were the clutch was not clearing 100%

RW

 

You've bought a shonky box........................

pants pulled proper!!

 

shouldnt your head be buried in your manuals!

RW, hmm.. yes. Others are fine though ...

 

Smart arse!!

I actually though it might be you changing too quick & beating the syncro's, but alas.................You bought the cadbury's quaife box

 

maybe raise your burberry baseball cap up abit so you can see where second is you c*nt

 

who threw you a buttered biscuit you scrawny little c*nt!

 

My sides!!

Thats why he doesn't want to come to saffend tonight.............

people will realise his caps fake!!!

 

i really cant wait to meet you franco

 

It's probably because Dave's tyres aren't very good in the wet

 

True battle of the giants!!

I'll call it a truce & buy you a big mac meal....................Butter in my hands

 

tone, its ok.. ive got proper ones now!


pm received btw skip

 

What oil did you put in the box Dave?

 

Bet its the Alcon clutch. I had a six paddle on my fiesta and it fucked up . Was shagged from the start as it was noisey but i didnt know it was the clutch as i thought its new so couldnt be . It started to get crunchy one day then all of a sudden i was stuck at the lights on the fucking a406 at rush hour

XFactor replaced it though so credit to him cause i dunno whther he has been able to get the money back from Alcon yet.

Cars off the road at the mo with suspected clutch problem again so i will be getting something different next time as i had the flywheel refaced and it was fitted correctly just like the first time and its fucked. I dont no for sure its the clutch yet though cause i cant be fucked to sort it at the mo but im pretty sure its going to be.

Heres a pic of it

 

Wes, the car has ford spec oil in the diffs and transfer, but some quiafe reccomended oil in the box.. i shall find out but i dont think thats the prob

 

I cracked up when I heard


No probs, you get Darrens number ok too?

 

yes mate.. cheers

 

 

Thats your problem i reckon, as Quaife sell Silkolene Syn5, they recommend it, it's not what you should use in your gearbox, trust me, been there done that with that oil in an MT75! Don't get me wrong, it's good oil, just not suited to the MT75 with syncros.

The crunching will be because the oil is too slippery, the syncros can't slow down fast enough, syncros go CRUNCH!

Goto Ford and buy 2 litres of their MT75 oil, job done, if you haven't mullered the syncros already.

 

aah really wes? thats a bit shoiddy then as Oilman told me to use that oil to spec


did you get the probs im experiencing then?


to be fair.. ive avoided fast changes etc.. so its only happened anout 3 or 4 times (crunching that is)

 

Nice one Wes about the MT75 oil!!

 

Clutch aint clearing.......IMO....Wes is right to a degree but i wouldn't think it would make the change crunch......

 

love you c*nt

hope you get it fixed

 

well it cant hurt to take the oil out and replace with ford...

pain in the arse though!


wouldnt mind oilmans thoughts on this!!!

 

I use the same oil in gearboxes and diffs................

Silly question time - clutch cable? Not touching the heatshield or melted through in any way is it? I had similar clutch clearing issues albeit 2wd when the cable was mullered.

Should have hydrailced the clutch when it was out anyway

 

Yep, except mine crunched from 1-2 + 2-3. If your clutch was dragging, surley it would crunch when you put it into 1st from Neutral.

I had an R+D bigtooth gearkit, after getting the gearbox rebuilt twice by R+D using the oil they recommended (Syn5, and everytime the syncros were changed because they were kaput), i went to another gearbox builder (around the corner from Quaife), his exact words were "don't use that shite in an MT75, use the Ford MT75 oil", which i did, hey presto no more crunching

 

You haven't got a Hydraulic clutch conversion???

I'm surprised, your attention to detail and prep on the car is normally superb....

 

cheers Wes, ill drop the oil out and put some new in...


anyone want some silkolene syn 5? only done 145 miles! roflol!!!



Pon, i will check the cable.. pretty sure its ok though

 

Thats great Richard, but 4WD's use don't use the same oils as 2wd

 

I didn't say I used that in a 2wd gearbox - I said I used it in gearboxes and diffs.......... not just my car

 

I just hope it's not too late Dave, MT75 gearboxes have been the bain of my cosworth ownership, i can remove / fit them on my own in 20 minutes now

 

whats a hydraulic clutch conv?

do i need one???

 

Hang on Wes - you don't even have an MT75 in there any more do ya?

 

they arent easy are they!

luckily my engine was out when i fitted mine! still a pain though!

out of interest, how can you remove/fit so quickly? amy set methods?

 

Ask Mike what the BEST mod he ever made to his car was
