Hi all,

ok im on the look for a solid flywheel for my mk1 superb 1.9TDI 130bhp model.

i need to stress that this is very important as my car is my livelihood with it being a taxi. and as such its clocking up the miles very quick.

does anyone have any knowledge regarding the solid flywheel conversion?

im unsure if this is correct but ive heard that the different bhp models came with different flywheels from factory.! can anyone confirm this?

i know that euro car parts have a solid flywheel conversion kit on there website,but i dont want to end up buying it to find out the flywheel is not right

oh and im starting to smell the clutch burning :(

HELP.

I've been thinking about this as well.

The Passat forums talk about a Valeo conversion kit with a double-sprung flywheel to absorb some of the vibrations that a DMF would normally, but I can't find out anything else??

if you do get some more info pelase post it

if i get any info i will post it up on here

but as it is i cant seem to find anything

if no information is available i may end up buying a new DMF and be done with it, but id prefer a solid flywheel.

there must be some skoda wizards on here that can enlighten us on this subject..??

come on guys, somebody must have some information regarding these conversions? :(

Solid flywheel will be fine as long as you don't drive the car at high load low revs at all times, where the bulk of torsionals come from on a diesel engine. Problem is a lot of people just drive all day at 1000-1300 rpm and the DMF and TV damper on the front of the crank just mask the amount of energy going into the system at those speeds which is why a lot of people just keep driving at those revs not realising the damage they are doing.

With the solid flywheel it will rattle around a bit at those low revs basically giving you a bit of feedback that you should not be doing that, and hopefully you will change down a cog.

I can't agree with the above. Crank torsional oscillation is very speed critical and will occur at several points throughout the engine's operating speed range.

As most vehicles will require only one replacement DMF per lifetime, I would suggest that departing from OE specification carries a needless risk. Fit a Sachs replacement flywheel and the vehicle will probably run to ground.

The transmission is also hammered by crank resonances - so a change to a solid flywheel could cause damage elsewhere.

DMFs were ONLY introduced as an NVH (noise-vibration-harshness) item, never a feature to improve the durability of transmissions. And I agree torsionals are a very complex subject, however, on a diesel engine, at low revs and high loads the firing is quite intense and due to lack of reciprocating system inertia relief much of the force gets transmitted into the crank, principally 2nd order vibrations (on a 4 cylinder). At higher revs the increased inertia relief tends to reduce the TV magnitudes.

so with a DMF if it bad to be driving at low rpm in any gear.?

i actually dont like the feel of the car when im driving below 1500rpm.

bumping an old thread but is there a single mass kit?
