Flywheel

[dex130]

Hello,
In august I had my gearbox rebuilt in my sport pd130 as it broke and I had new clutch put in. At the time the mechanic said I could do with a new DMF however as the time i could not afford it so i didnt bother getting it changed.

I recently took my car in for some other work to a different mechanic. The mechanic commented on the amount of vibration the engine was producing due to the knackered DMF something to do with is being grease packed and the grease thats escaping causing an inbalance till it warms up.

Im hoping to get the DMF changed at the same time as i have my timing belt changed as it is annoying me as i want re-map. I was just wondering what my options are ?

Im considering a SMF but im unsure how much vibrations that will give and if it will be a worthwhile investment or should i stick with a DMF.

IM also considering a uprated clutch so i may aswell get it done at the same time to save labour. I was wondering if a uprated clutch comes with a new flywheel or if ya have to buy them seperately and if i go with the SMF will i have to get a different clutch if I decide to stick with the standard one?

If anyone could suggest a good DMF and uprated clutch combo or a SMF and uprated clutch combo that would be great.

Finally has anyone an idea of the labour charge for a job like this or if it is possible for a diy mechanic to do (although my dad who used to be a qualified mechanic will be helping).

Im really confused so any help will be appreciated!!

DMF to SMF is available from Valeo and Sachs i think (have to check on tdi)

but driven 3 now and they are a little harsher but not 'in ya face' and might just be me expecting em to be

once bedded in a bit its a job to tell

 

[dex130]

What yea mean by harsher mate?

 

[Fl@pper]

just feel about 10% ish more vibration

probably best described as feeling the difference between a normal road and new smooth tarmac very similar effect and i only really noticed when actually on the pedal

Labour would be about £200 to replace a clutch. Doing it yourself is the usual story of if you have the tools and knowledge then yes its a simple job as the uprated parts are the same design and fitted in the same way as the stock clutch. Sachs and Helix are the two main clutch makers in England, Sachs is slightly cheaper then Helix but Helix holds more torque. As long as you get a clutch with an organic disc not a cerametallic disc you will not go wrong with either company. If you fit a SMF you will get a rattle when the gearbox is in neutral and unless you are aiming to have a hybrid turbo fitted later on there is no point just stick with the DMF the the clutch/gearbox was designed to have.

Cheers mate, love the magazine write up !

I agree with Devonmikeyboy. Don't go down the SMF route. That's a painful memory for me. Back with the DMF now.

Original or some other brand?

My DMF is knackered, it shakes and vibrates the car at low revs when accelerating. I have now stopped accelerating at low revs but its taken the fun out of my diesel . Does anybody know if i can send it in for just a SMF to be fitted with my current sachs uprated friction plate?

Original SEAT DMF.

Cheers for the help everyone just wondering if i will need to get an uprated pressure plate and friction plate or do i only need the friction plate and is it ok to run these with a standard dmf.

ph2858 just out of interest how much was your friction plate mate and where from?
Cheers

I'm running a Helix clutch with standard DMF. Admittedly can't use the power below 2k revs.

 

[dex130]

What type of torque are you running mate? Did you just get the uprated friction plate?

I haven't had it rolling roaded since my latest remap so I can't tell you.

I don't know what they did tbh. I think they replaced the whole clutch. Cos i learnt after that I could've just changed the friction plate and saved me £££s! I'll go get my last rolling road printout and let you know what the torque was then.

 

[dex130]

Cheers mate i really want a remap but dont know if i could trust myself with not flooring it below 2k

They did two runs and messed them both up. One run read at 242ft/lb and the other at 255ft/lb. But the power curve was all wrong as they reckoned it was spinning on the rollers. But it's been mapped again since then.

 

[Tall-Paul]

Mines got 290lbft at 2k revs, the clutch+fitting was just over £700

To bring the thread up again...


How does the OEM DMF cope with a hybrid turbo on an tdi (220-230hp)? Would it last or would it start to vibrate relatively soon?

And has everybody who has gone hybrid changed to an SMF?

 

[Tall-Paul]

Should be able to let you know soon

 

[devonmikeyboy]

The DMF should be OK with a hybrid turbo running but like everthing else the more power you put though it the more likely it is to brake. If you intend to stick to 220-230 bhp i would just stay with the DMF. I am running 330bhp with no DMF issues.
