1*2 Flywheel Step Height?

[Razmann4k]

Hi all, I'm in a real pinch. I bought my 182 in February with a ruined clutch kit and had it reconditioned (my mistake) so my clutch kit needs to be replaced again asap, this time with a proper OE matching part. As for my flywheel, that was also sent in for skimming at the same place that reconditioned (scammed) me, and they removed the step height completely. So this time I found a proper racing engineer locally who should be able to give me his opinion on whether my flywheel is still salvagable or FUBAR. I'd just like to know if anyone has the step height measurement for this flywheel as the engineer isn't a Renault specialist, so I doubt he'd have that info to hand.

I'm in South Africa where 1*2 parts are next to non-existent, and I'd prefer not to import from the UK/EU. Now I know according to NorthloopCup that these flywheels are not the strongest and removing material isn't ideal, but I've got little other option. If it is indeed FUBAR though, I would consider a secondhand good condition flywheel.

Thanks.

Hey, did you end up finding this out? Also in need of the step height

Hi, I managed to find an almost new unmolested flywheel a while ago now, and while I didn't write down the exact step height, it is definitely less than 1mm, far less than I expected, I believe it was 0.5mm. However, as NorthloopCup advised me, skimming the flywheel is not a great idea and a secondhand replacement would be advisable instead. I was lucky enough in South Africa to find one from a Renaultsport mechanic who had one off his 182's original engine (he swapped in a Megane turbo engine) after a lot of searching, so if you're in Europe you should definitely have an easier time than I.

Edit: I see you're an Aussie, so scratch that. Still, I'd imagine there should be a unicorn like the one I came across for you too, 172/182s are rare over there too from what I've seen but not impossible to find, even Mighty Car Mods had one on the channel 😂

I can definitely recommend Spareto for any other parts you need that you can't source locally, but it's best to buy a lot of parts to share the shipping cost. The rear main seal should definitely be replaced (I got a good Payen one off Spareto), and it's a bit of a tricky job, it mustn't be pushed in all the way, there should be about 3-5mm's sticking out evenly (check the original one if you haven't removed it yet). Some other tips from my nightmare experience is to never grease the spigot shaft AT ALL, only a bit of Litho HT grease on the guide tube's contact points with the pivot and clutch fork, otherwise the shaft will gum up and cause a VERY stiff pedal (ask me how I know🥲). The flywheel bolts can be reused according to the Renaultsport mechanic I spoke with but mine were only a few months old when I did redid the clutch job anyway after I bought them new for the the failed recon clutch. They must have plenty of blue locktite though not only to keep them from coming loose but also to keep oil from leaking out of the threads (yes, the threads are exposed to oil by design), I just vacuumed out the old locktite and the residual oil before drying with a paper towel as best as possible to get accurate torque readings.

*Never grease the spigot shaft OR the guide tube at all
*Grease the thrust bearing's contact points with the fork, and pivot, not the guide tube, sorry
