impulse922 Posted March 7, 2013 Report Share Posted March 7, 2013 That disc is not DM. Not enough depth to the friction material. I posted the Spec disc for comparison, but the S60R disc has the same OD/ID and depth if friction material. EDIT: it is possible that it is a non-60R disc & pp, BUT until you can confirm it by either the LUK part numbers or physical comparison, you can't assume that's what it is. Steve, if you want to use the S60R clutch (good for 350whp) you may need a different flywheel. All the DM's are not the same size. His 01 probably has a different input shaft anyways.

Ghost Shadow Posted March 13, 2013 Author Report Share Posted March 13, 2013 i read omewhere about the trans having different input shafts too. whats the difference between luk, spec vs oem? whats better are they all the same? i want to do this once not twice Link to comment Share on other sites More sharing options...
GLTurboguy Posted March 13, 2013 Report Share Posted March 13, 2013 From what i hear, spec is garbage. OEM is Sachs, and I hadn't heard of LUK until i received my kit. But apparently it's mostly used overseas. Link to comment Share on other sites More sharing options...

If you're not going to be looking to bump the output significantly, no reason not to stick with Volvo. Your VIN should indicate which clutch to use, based on the spline count.

don kalmar union Posted March 17, 2013 Report Share Posted March 17, 2013 I now have a kit in stock comprising of a specially machined Kalmar Union single mass lightened flywheel combined with an AP Racing kit of cast aluminium cover and organic disc, presently just for the M 66 box. You can find it here on my website:http://kalmar-union.com/parts/volvo-s60_s80_xc70_v70_-transmission/ The price includes UK VAT of 20% which I do not charge for deliveries outside the EU.

ande0549 Posted March 18, 2013 Report Share Posted March 18, 2013 you're not looking to do crazy power. so, pull the trans, new clutch kit from Will (above), new slave cylinder, throwout bearing, master cylinder.....not sure how dual mass flywheels work, but highly doubt you need a new one....get yours resurfaced for about $10 and you're done. When I had my clutch done back in '05 the mechanic said he was unaware of any way to resurface a dual mass flywheel so we replaced it with a new one. Not a cheap part by any means at around $700+. Was my mechanic at the time correct or has any one had direct experiene with turning a dm flywheel? Link to comment Share on other sites More sharing options...
lookforjoe Posted March 18, 2013 Report Share Posted March 18, 2013 Definitely NOT $10 to resurface a DM flywheel. It's not a brake rotor, even those cost more than $10 to resurface, unless you have slave labor? Since it is a two part unit, with the disc surface 'floating' in the outer plate, it is NOT a straightforward operation. My machine shop wouldn't do it, I'm sure there are those that will figure a way to properly secure it for resurfacing. Link to comment Share on other sites More sharing options...
ande0549 Posted March 18, 2013 Report Share Posted March 18, 2013 Googled it and apparently there are shops that resurface DM flywheels in the BMW world, so thats good to know. Seems like the consensus is that replacement of a DM flywheel is recommended and more likely warranted when doing a clutch job but resurfacing can be done if the flywheel is within spec and hasn't been abused. I think the trick would be to find a shop with a solid reputation of turning DM flywheels for a higher volume vehicle and going with them if one wants to save some cash and retain the clutch feel of a DM setup.

phonsa Posted March 18, 2013 Report Share Posted March 18, 2013 Sorry to hijack, timing is right for my clutch replacement as well! Does anybody know the approximate HP limit of the 850R clutch before it starts slipping? Just got my 19T Billet wheel and ARD Blue tune on gasoline completed (E85 tune soon) and its making great street friendly power. ATM stock clutch is slipping from 4.5k+ RPM at WOT, and i'm leaning towards the 850R clutch. Beyond the 850R clutch what are the alternatives to support 350HP - 400HP? Thanks guys.

GLTurboguy Posted April 3, 2013 Report Share Posted April 3, 2013 850R clutch disk with Sachs 707 pressure plate should do the trick. Just get the Flywheel re-pinned. Ok so I have a question. Will the S60R clutch disk work with the SM Flywheel? The 850R clutch won't fit because i have one of the newer M56H with the larger input shaft.

fattmatt805 Posted April 16, 2013 Report Share Posted April 16, 2013 my question is, how do i know if i have a DM or a SM flywheel? without removing the tranny that is. i know i have an internal slave. i'm about to order my r clutch kit and i assume i need a new flywheel, so i'm trying to figure out if i should get a DM or a SM from the pick n pull. also, anyone have a P/N for the internal slave cylinder?

Volvo5.0 Posted April 16, 2013 Report Share Posted April 16, 2013 If you know you have an internal slave, then you have a DM flywheel. There are cars that have been manual swapped that might have an internal slave and a SM flywheel, but if you car is a '98 and is a true T5M with internal slave then it came with a DM flywheel from the factory. If you want to use the r clutch kit (272218) you need to get a SM flywheel. Link to comment Share on other sites More sharing options...
