hoona6 Posted January 14, 2010 Report Posted January 14, 2010 So the Hairnet needs new clutch plates. These I have. I'm also going to get new springs and gasket. Thing is I've had a look in the Haynes and it reckons 3 spanners of mechanical knowledge. I'm a spanner alright but not quite three. Sooo, anyone in the Southampton area who meets the bar fancy helping me out? I'll reward you with bacon sarnies with home made bread, cups of tea/coffee/hot chocolate and of course a healthy dollop of mana* Pretty please? * you DO remember pbmagforum.com doncha?
jollygiant Posted January 14, 2010 Report Posted January 14, 2010 Can you move to norfolk and I'll help!! If you can't get any takers it shouldn't be to hard really just take it slow and take pics as you take it apart so if you are not sure where a certian bit goes on the rebuild you have a pic. Sorry I don't live closer cos I like bacon sarnies and I love em if they are FREE!!
millerich Posted January 14, 2010 Report Posted January 14, 2010 It might not be as hard as you think. I did one last year, admittedly not on a hornet, and it was just a matter of taking case off, undoing the bolts, taking springs and plates out then revering the whole process. Remember to soak your new plates in oil first. I felt very pleased with myself for ages having done mine. Mind you I had wasted most of an Enduro race with a slipping clutch the week before when I knew the plates needed changing and I thought oh they'll be alright for one more event. Doh!
lorenzo Posted January 14, 2010 Report Posted January 14, 2010 Your only issue will be stopping the clutch turning while you undo the centre nut. Stick the bike in gear and then stick a big bit of wood in the back wheel against the swingarm. Also, if you've got a big cushion/matress thingy, or simply have no regard for your bike, you can just push it over onto its side and undo the clutch covers etc without any worries about the bike leaking oil etc. Get a sandwich bag and put a cupful of oil in it to soak your new clutch plates overnight before you do it, and job's a good un. Allow about 2 hours to do it and you'll be just fine.

I thought that held the clutch basket in place. Shirley you only need to undo the bolts holding the clutch springs in place, and whip the clutch plates out, without having to touch the centre nut? edit: Hoona, have a look at this thread http://pbmagforum.co.uk/index.php?showtopic=7523 there's a handy hint for using a cardboard template for the bolts that hold the clutch cover, saves a lot of 'which bolt goes where' fannying
Pete Posted January 14, 2010 Report Posted January 14, 2010 Hoona6, I'd say its probably 3 spanners due to the consequences of getting it wrong, but don't worry, the actual job itself is simple enough. The most difficult bit is getting the old gasket of the engine/ clutch casing. I did my gs500 hack a little while ago and the job in total took 2 hours (30 minutes of which was scraping the old gasket off FFS!!!!!) Like the above post, take it step by step, oil out, casing off, pressure plate off (careful with the thrust washer), old plates and springs off, new clutch plates on in correct positions with pressure plate back on using new springs torqued up as Haynes direction , old gasket off casing, new gasket on, bolt up, fill up, run for 10mins and check for leaks. However, if you really don't feel able and you can't get anyone local to help, take it to your local bike shop, its just not worth the worry otherwise. Pete
rusty Posted January 14, 2010 Report Posted January 14, 2010 A digital camera's your friend! If you're not sure about anything, take pictures before/after each stage then you can refer back to them when you're rebuilding it. I've done this a couple of times and it's got me out of some potentially sticky situations!

dodgy_tom Posted January 14, 2010 Report Posted January 14, 2010 Can you bring it in the car this weekend?
hoona6 Posted January 14, 2010 Author Report Posted January 14, 2010 Can you bring it in the car this weekend? The bike? In the A3? Doubtful!
Gregorious77 Posted January 14, 2010 Report Posted January 14, 2010 Clutches are easy, I live in gosport if you really need a hand. as said above you dont need to undo this big nut unless you take the basket off and you need a special holding tool for that like a giant mole grip which I have. You only need to undo the 5 or 6 bolts then take all the friction and metal plates out and replace with the new ones then bolt it all back up again. Very easy job.
TKDMitch Posted January 14, 2010 Report Posted January 14, 2010 You'll be fine hoona. I'm no mechanical genius and I did the clutch on my DR (now Tom's) with no problems at all. It's really not a big job. If your happy doing an oil change then you're competent enough. Take notice (or photos) of what goes where as you pull it apart and be methodical, you'll be fine. Mitch
porter_jamie Posted January 14, 2010 Report Posted January 14, 2010 the worst bit is scraping the old cover gasket off. major ball ache.

I had a **vague** idea that I needn't remove the clutch basket just to change the plates but my Haynes seemed to suggest otherwise...that said it covers overhaul of the clutch rather than simply plate replacement. I guess the only thing to do is to whip the lot off and see what's occurin'. What could possibly go wrong?

Gregorious77 Posted January 14, 2010 Report Posted January 14, 2010 Found this Linky Follow steps up to removing the plates. then reverse, make sure you remember the order of friction and metal plates thats it.
dodgy_tom Posted January 14, 2010 Report Posted January 14, 2010 Oh and don't forget to soak the new plates in the old engine oil overnight before fitting them...

I guess the only thing to do is to whip the lot off and see what's occurin'. What could possibly go wrong? hopefully, not much Glad it's of help. I'd definitely say you should give it a go - it's really not that technical and it will give you a deep inner glow of satisfaction once you've done it. It's definitely worth having a soft faced mallet to hand; even once all the clutch cover bolts are removed, it will probably need some gentle persuasion - keep an eye out for any dowels which might stay in the cover or the engine case. And don't forget to get a new gasket for the cover. The trickiest part I found was getting the pull rod to re-engage with the clutch cover - it's not technical, just fiddly. Just make sure that the pull rod is fitted into the pressure plate before you fit the springs and tighten up the bolts that hold it and the springs in place. on the R1, you can get away with removing the clutch cover without having to drain the oil first; due to the stacked gearbox the clutch is well up above the sump. But you could always combine it with an oil change anyway, that never hurts
