M-tech....

[MattBrown]

Is this stuff any good?

Its for an xe, then hopefully a let in many years!

Will they break?

Or are they worth the cash??

[djbrowney]

i presonaly dont like the m-tech shafts being slightly thinner than the ones that chris ashley sells in certain places, the hubs are just the same as any other's though !

sorry i forgot to reply to your text the other day lol

[sparkie1401]

i have M tech shafts, they look decent quality but i cant really tell you anything else sorry

i hope they are good, or i will be pissed

[Adam]

I think its M-Tech stuff that a few people have said about they break easily (shafts and hubs)

[MattBrown]

Ohh cock!

I hope not:(

I may have a set coming my way, and they will get the sh!t kicked out of them!

Especially if the car goes on track/drag strip:)

So the hubs, are they standard nova carriers, with the stock bearings, with machined down hubs pressed in??

[Benn]

I wouldn't touch them with your co*k.

Seen 4 set of their hubs break my self. Badly machined.

Hubs are Cav hubs machined down to fit Nova bearings.

[Adam]

There we go/\

TBH just stick with OE shafts.
Thats all i use and its not like my car gets driven softly

[sparkie1401]

oh dear

TBH one of my hub flanges has play in it and it "brand New"

they are basically look like factory nova flanges with the splines suited to big block CV joints so u can use them from your donar astra GTE

so should i get some more flanges from IE chris astley

and what should i do with my shafts? i have no others i cut throught mine way back in 2003 when i stripped my astra as i already had the M tech kit ordered?

my xe is only 150 - 160 BHP so i should maybe see if they last first? then have some made maybe?

[Mike]

Spark, it might pay to invest in another set just in case chap, or at least contemplate getting some spare's if your planning +powerz on your XE motor.

[Graeme]

I run both for nearly two years without any problems and even had an unexpected incident with a kerb and held up OK, only sold them due to acquiring an equal length set up with out the Astley headaches. I was going to keep my existing (mtech) hubs but got my new ones free due to being modified to use rose-jointed track rod ends. I think when I bought my Mtech conversion kit from Pvd it was the first full kit available and had to wait for weeks for it to arrive, this was long before they were available from an UK suppliers/manufacturers

thats what most of them are though :thumb:

chris ashley buys his in brand new and machines them down !

[Graeme]

Slighty of topic but are the only alternative modified knuckles like the ones in your thread Browney? How much safer are they for fast road use?

these one you mean ???

they run a full size hub flange and havent ever hurd of anyone breraking a set yet :thumb:

[sparkie1401]

mines exactly like your mr dixon

came from PVD direct form the land of weed and waited quite a few weeks

so can i use a stabndard shaft with a standard nova flange and F20 g/box?

or is it cut and shut option only

[Graeme]

I think the options are 22 spline with changed inners, the current machined hubs like what Chris/Mtech sells, or what Browney has posted above, which admittedly are porn but a little bit too pricey for me

[djbrowney]

im sure they could be done cheaper but i refuse to use cheap bearings mate :thumb:

im sure if 5 people wanted them then i could get them done at a lot less but that probaly not going to happen lol

will look at the link later but its extar slow at the mo

is that Nova TD shafts or sommat? with cav mk2 16oo inner cvs?

i never actually counted the splines on my M tech jobbies or on my standard 1200 spi nva flanges

[MattBrown]

Hmmmm, Im having second thoughts about the shafts now:(

If the 22spline stuff (I already have) is better, then its just a waste of money:(

will look in to it mike or sourcing OE shaft set up

i doubt ill up the nova power but ive not driven mine yet so im not sure if itll bore me or not

and i have the Evo as a big brother, and i really have spent enough money on my XE (not engine wise) and i want a house this month

[Adam]

Wouldnt really say better but its not like oe shafts snap all the time....

[Graeme]

I'm not critising at all mate they look fantastic quality, If Royal Fail pay up I'm nearly half way there, all of a sudden doesn't seem that dear, result

[Benn]

If you wanna run std hubs then yes use gte/gsi 22 spline shafts.

My old ones took about 3years hard abuse and where fine, people have run them for ages.

After seeing a friends Corsa with the wheel hanging off cause the hub snapped and looking at the hub the machining wasn't well done.

New or old hubs that doesn't really matter it's how the machining is done. If done right they'll last for ages.

and you just change the inner CV's?

i will try source some then for spares incase my M=Tech are poopoo

cheers Benn

[Benn]

Yes, if you run the gte/gsi shafts then you just need the mk2cav 1.6 (88year) cv join (inner) but they are very hard to find, i tried 6-7 different makes and none where right.

oh right, u work at a motor factors dont you? so are you refering to new ones?

[Benn]

I do, we sell "new" being rebuilt ones, as there's no such thing as a new new one now.

[sparkie1401]

yeah i understand

new as in recon

i have a good friend in a motor factors through my old work, so i best get him to find some

what do i need to look out for to get the correct ones

[Iain]

Their defining feature over other Nova CVs is that the part where they join the boot is thinner than the main body of the CV joint. Not sure if that differentiates them from other Cav CVs tho. And obviously 22 inner splines and ??? outer to suit an F20 (check a std one for how many).

[Benn]

34iirc spline outer (in to the box) 22 for the shaft.

Remy,
Delco,
Firstline,
Q&h,
drivetech,
And a few others i tried where all wrong. They where big block both ends.

[Lee H]

I have some brand new Chris Astley shafts I'm willing to part with if anyone wants to upgrade from their MTec ****e?

our factors had them on the shelf the other day. Shaftec PJ16.

[MattBrown]

So the issue is the shafts?

Darcey told me this, he was running 300bhp through them with no issues, then the circlip broke, the shaft slid out slightly, and snapped the end off:(

hmm, seriously thinking of not having them, but why would they make them if they're crap??

[discoinferno]

i run chris astley shafts (equal length) and have no problems up to 382ft lbs i know g8wcc old nova turbo ran over 400bhp with mtech shafts and had no issues at all!

[mayhem]

mtech sucks.

i dont know if you guys have the same stuff as we have, but here the shafts are welded! and he's f*cking expensive.
for instance:

gasket for powercap. Mtech sells them for about 5 euro. only problem is that we know it's just the gasket from a c20let tophat, costing 0.90 cents at the Opel dealer....

Ah not heard of them, i'll have a look in to that. Cheers dude.

What issue are you talking of?
I broke a custom shaft when the circlip came off and it snapped the end off too.

Do you know how much they were/are?

[sparkie1401]

Benn will no doubt come up trumps finding these

ill ask my bud to

[Lee H]

Do you know how much they were/are?

Andy bought some. Think they were £42 plus an old CV but could be wrong.

[Benn]

Benn will no doubt come up trumps finding these


You know if i can as i'll put up a for sale thread..lol

[John]

A freind of mine also ran m-tech stuff. I liked it tbh, the shafts have ridges on to fit the gaiters correctly, instead of a (poor imo) straight shaft. He drove it like he'd stolen it for 2 years and never once had any problems.

[Benn]

I've never seen their shafts, so cant comment to that.

[mayhem]

http://i30.photobucket.com/albums/c341/mayhem22/SP_A0706.jpg


my mtech kit from about 2 years ago, as you can see, the shafts are welded... i'd never use them again, seen to many break (normal c20xe of even NE use)

[Benn]

I ran a cut an welded short shaft for about 3years with no probs. Wasn't mtech tho.

At the risk of sounding pedantic, i can't see where they're welded?

[Benn]

See the big lump in the middle John? That's the sleeve and where its welded.

[John]

Just looks like it's been machined?

[djbrowney]

from the shafts i have seen there machined, not welded :thumb:

[mayhem]

mtech shafts are welded, there's a reason we all buy Cris ashtley of 22 spline shafts ;)

[Lee H]

Can't see why they'd go to the hassle of machining that lump in as it doesn't serve any purpose and seems to make a weak point for the shaft to snap.

[Benn]

Have they not been welded then they've machine around the welds to make them look tidy? As Lee said they wouldn't machine then leaving a bit lump in the middle..

[djbrowney]

that does make perfect sence :eek:

[sparkie1401]

i was told the lumps were to balance things up/weight distribution

was that nonsense/kidology? PVD told me that

[John]

I'm sure the weights (big bits in the middle) in the shafts are for counterbalance. I've just looked at some pics iof some i sold, in my pb account. If they have been welded, the welds must have been fookin massive, then machined down.

[Lee H]

Wouldn't they be sleeved and welded and then machined down, hence the lumps are the sleeves?

[djbrowney]

has somebody not got a picture of a broken one ???

[sparkie1401]

has somebody not got a picture of a broken one ???

good idea that man

[craig green]

What does it matter, they shear off so part of it is left in the bearing & the other half is bolted through the back of the brake disc. You lose drive.

I know of 3 cases where this has happened & MTECH/LMF claimed each case was the 1st they had known to break.

[Graeme]

I've just sold a set of theem shafts today and the were from a blank, there were no welds

[craig green]

The Nova shafts have a balancer weight on the long one, I believe the Astra GTE 16v & Cav 16v big block shafts have a machined in weight or bulge, pretty normal it seems to me.

[Benn]

I know of 3 cases where this has happened & MTECH claimed each case was the 1st they had known to break.

Phil from Cs lives near me and after me to give him a hand, the wheel was almost comming off. He got trucked home, when we jacked it up the only thing holding the wheel on was the disc.

The hub has snapped, snapping the end of the cv off to.

When he rung the mtech dealer they said " oh again? We'll get you two new ones out, best to change the other way too" So they know it happends. And will again. I had heard things about them before, this finished it off for me..

[Benn]

that does make perfect sence :eek:

Tbh if i was cutting, welding and sleeving a shaft to sell its what i'd do to make them look tidy. The shaft i used you could see the welding at the end of the sleeve.

[Mazz]

What about this poor bugger who broke his M-tec shafts at PVS09

Not sure who is though, apart from pissed off m-tec customer :confused:

[sparkie1401]

oh dear, thats pants

[Lee H]

Exactly where it would be expected to break though, that's why I don't understand the machined in lump.

[Mazz]

iirc he said it was the second one that had broke too :(

[Benn]

That must be the most outer weld(join) guess its the weakest part.

[sparkie1401]

could this guy re weld/repair that and re sleeve it or is that asking for trouble?

[Benn]

Asking. I want a longer sleeve too.

[mayhem]

the all break at that point. i've even seen new mtech shafts with corrosion damage! imo just old shafts from the scrappy who are blasted and welded and sold for a stupidly high price. (1 mtech shaft is the same price as 2 proper astley shafts).

overhere mtech also claims that he never heard of it, while there are a few guys on opel-forum.nl who had this.. i just looked up that thread (early 2005 lol) and in the first 5 pages there are about 10 guys with shaft problems
(keep in mind, in those days mtech also had a version with big gearbox side and small wheel side, so you didnt need different hubs, he stopped with those as the snapped every 2 miles)

http://members.lycos.nl/corsa2000/forumplaatjes/gebrokenas-5.jpg

and the "new" mtech shaft he got

http://members.lycos.nl/corsa2000/forumplaatjes/nieuwe%20as%20-----5.jpg


i'm anti mtech, i even sold my mtechpowercap and bought a Mantzel one, cause i dont want mtech on my car lol
the guy rapes you in the a$$ with his prices imo.

[Benn]

Eek^

[djbrowney]

once a bodge always a bodge !!! just imagen if thats snaps doing 120/130 + the damage that would do :confused:

[MattBrown]

Im so glad I aint bought them!

They look crap!

If ive manage to go through 2 cvs in a 1.0, I can only imagine the heart ache with them!

However, Spoke to a nw member tonight, he ran them for 2 years, kicked its head in, and no problems?

Could be the problem of running too low? Cv's constantly not streight?

[Benn]

Scarey enough at 50ish.. (thats snapping the end tho)

How have you done that in a 1lt? What do you drive like? Either that or youve had knackerd ones to start with..

Can see you've running anyway near as low as some Nova's on here.. Plus that's a mith.

[Lee H]

A shaft with any cuts or joins in at all is going to snap if you drive the car hard enough. I'm sure of it.

[mayhem]

as said, these pics are from 2004/2005. mtech has improved his quality. the shafts i had looked good, but the better price and the fact that there not welded is reason enough for me to run cris astley shafts.

with street use mtech's will hold, but i dont want to do a proper burnout on slicks with mtech shafts..

[Count Vaux Alot]

I ran mtech on my 1.7td corsa with 200 lb ft its still in the family now and has done 20k on those hubs and shafts (the corsa ones don't have a bulge in the middle though). Some of those shafts look fooked though!

[deniz]

I couldn't contact with cris astley and I bought couple parts from M-tech. They look fine to me.
