Title: Clutch slipping Post by: uberranger on October 22, 2012, 09:08:49 AM So, my clutch is beginning to slip when shifting and gassing it hard. It won't slip after it gets all the way in gear.
So, simple fix, new pressure plates, right? Well, what about doing a wet-to-dry conversion, because that's actually pretty close in terms of cost. I've seen the DIY guides, and it really looks like something I could do. My question, I suppose, is this: Is there any really good reason not to do this? I heard a couple dry clutches in person and didn't really like the sound a whole lot, but it was really cool to be able to see all the spinning shiny bits. Title: Re: Clutch slipping Post by: Slide Panda on October 22, 2012, 09:55:47 AM What model monster? But I'm assuming it's a wet model - so what oil are you using?
If your clutch pack is worn, then yes it'd need to be replaced. Not the pressure plate that generally never wears out. Obviously I don't know your background/skill set, but a wet to dry conversion is going to cost A LOT more than a set of new set of friction plates. If you're capable of doing all the labor and machine work, it's still an expensive thing. You'll need (at least) Dry clutch engine case, seals etc Dry clutch, hub, basket, pressure plate and clutch pack You're looking at $150-200 in parts vs $750 or so in parts - labor not included. Title: Re: Clutch slipping Post by: uberranger on October 22, 2012, 04:27:34 PM Well...I'm not a mechanic by trade, but I bought the bike savage in pieces and rebuilt it (motor out, fixed mount, new wheels, replaced valve/rocker arm, swingarm out to powder) and some other odds and ends. That's where I'm at skills-wise.
As far as the parts are concerned, I was gonna use parts from a 748 (thought they'd fit [oh, and the bike's a 2006 S2R 800, wet clutch]), and I see those running a bit lower than what you say (though there might be a reason). a quick search on fleabay yields the following: INFO ------------------------------------------------------------------------ related thread: http://www.ukmonster.co.uk/monster/showthread.php?t=37403 (http://www.ukmonster.co.uk/monster/showthread.php?t=37403) It is a 620, but I was under the impression that the parts were of similar dimensions; if not, I imagine one of the suberbike pieces would work...or from an S2R 1000. ------------------------------------------------------------------------ PARTS ------------------------------------------------------------------------ case: http://www.ebay.com/itm/DUCATI-748-CLUTCH-CASE-/250944651657?pt=Motorcycles_Parts_Accessories&hash=item3a6d778189&vxp=mtr (http://www.ebay.com/itm/DUCATI-748-CLUTCH-CASE-/250944651657?pt=Motorcycles_Parts_Accessories&hash=item3a6d778189&vxp=mtr) basket: http://www.ebay.com/itm/Ducati-748-916-996-Clutch-Basket-OEM-/320724006996?pt=Motorcycles_Parts_Accessories&hash=item4aaca3f854&vxp=mtr (http://www.ebay.com/itm/Ducati-748-916-996-Clutch-Basket-OEM-/320724006996?pt=Motorcycles_Parts_Accessories&hash=item4aaca3f854&vxp=mtr) + a couple more items, and some machining - I have a buddy for that XD ------------------------------------------------------------------------ Does everything look in line to do it for sub-$250 at least? I was getting hopeful there for a second. Title: Re: Clutch slipping Post by: Slide Panda on October 22, 2012, 04:52:28 PM That basket looks like the one I tossed in the trash... it's probably usable... for a bit. But it's seen a good bit of action
From that UK thread - there's some important questions you need to answer - really one and that's what year Monster is yours/Is it equipped with an APTC clutch? If it's got that clutch, then you probably can't use the hub, pressure plate, springs etc. Search around there should be a thread in here from a while back documenting this process on a APTC equipped 620 Title: Re: Clutch slipping Post by: uberranger on October 22, 2012, 05:20:23 PM Yeah, that was just a quick search. ;D
I know the 5-speed 620s are not APTC, while the 6-speeds (2004+?) are. The OP on that other posts mentions needing nearly the entire 748 clutch, so I imagine you're spot-on there. Mine is a 2006 S2R 800, which I'm fairly sure does have the APTC. I've just about convinced myself to do this, as it's really cool. I've seen a few in person and like how it looks. I know that's about the only good point (that and maintenance maybe), so I'm still a bit on the fence. I'll look around a bit for the thread you mentioned. Title: Re: Clutch slipping Post by: Slide Panda on October 22, 2012, 05:27:26 PM yes, yours is APTC equipped. I don't recall if the change over was 04 or 05... But I know the wet monsters from 05 on had it for sure. Nearly all the clutch? I think you're going to need it all. Pack, pressure plate, hub, basket, springs, spring retainers and bolts... soup to nuts I expect.
