xtzrick Posted January 16, 2011 Share Posted January 16, 2011 Alan Found your problem whilst brousing google so thought I'd join group & answer your question. Your head will bolt straight on to the mz bottom end. Personaly I'd mend the hammering. I had a similar problem on my '97 tenere, as have loads of people with szr660s & mz skorpions. The noise is caused by the balancer shaft drive gear becoming loose & banging against its' locating key, the key will eventualy shear & the balancer shaft will smash into your crank! Take your water pump off & you'll see the drive gear on the crank. If there is any play in it, that's your problem. Note the tab washer will probably be in place & undamaged, wear occurs between the 2 inner most washers which has the same effect as losening the nut. Yamaha appear to have solved the problem, the parts I bought had been made by a different process from the original ones. Let me know if you want to mend yours & I'll send you the part no.s from "oemmotorparts.com" & tell you what to do. Rick. 1 Link to comment Share on other sites More sharing options...

Alan m Posted January 23, 2011 Author Share Posted January 23, 2011 stripped the clutch cover off today wood ruff key was split in two on the balance shaft and the washers were worn down luckily the key ways are fine but new parts are a priority now the plus side is its not the crank so no new motor needed i hope see pics completly split lucky it did not seize badly worn away Link to comment Share on other sites More sharing options...
xtzrick Posted January 24, 2011 Share Posted January 24, 2011 Nice pics mate. I'll give you the part no.s from "oemmotorparts" again & as I said these are genuine yamaha parts but not yamaha part no.s. It might be cheaper to buy from a yamaha or parts dealer, in which case you need yamaha part no.s (look on their microfiche & point @ the parts you need). Then I'll explain why I used genuine yamaha, then a few tips. Go to "oemmotorparts" click on "yamaha" then "xtz660" then any year, theses parts are all the same. In the clutch section you need: no.2 key YA00245281 no.3 tab washer YA00243821 no.18 tab washer YA00243839 In the crankshaft piston section you need: no.15 plate washer YA00241764 2x no.16 washer YA00120022 no.26 key YA00245262 no.29 tab washer YA00243729 You also need a new gasket (cut new 1 or buy an after market kit). New oil & filter (your old 1 is full of swarf) When I got this problem I read lots of fixes on the 'net. Some, with experience in racing, say the only fix is to fit a solid balancer drive gear from "slipstream" I don't know when they last tried genuine yam replacement parts & I believe yamaha fitted a "cush drive" for a reason, probably vibration. I can't remember if they mention washer no.15 which on mine was the cause of the problem. Before I stripped my engine I had come to the conclusion part no.16 was too soft, I ordered a new 1 to use as a template so I could get new 1's made out of a harder metal. When it arrived, me & a blacksmith friend compared original with new. The original washer is plain in colour, has rounded edges & if you hang it from string & tap it with a screwdriver, the ringing doesn't last long. The new washer is mottled in colour (indicating it's been heat treated) has less rounded edges (indicating it's been machined) & in the ring test, it rang alot longer (indicating it's harder metal). We came to the conclusion yamaha have already addressed this problem. Washer no.15 was the cause of my problem, the original was warped by the stamping process that formed it, causing high spots that rub into washer no.16. I don't know if yamaha have addressed this, I flattened my original 1 on emery cloth stuck to plate glass. When you get your new 1, make sure it's FLAT ON BOTH SIDES! (If you use emery cloth, rotate the washer now & then to keep the sides parralell & make sure the washer's still thick enough to hold the nut off the crank boss when everything is assembled) To undo & tighten the clutch center nut, I put the bike in 1st & stood on the rear brake, I also put a screwdriver through the back disk, to lock the rear wheel (THIS METHOD IS LIKELY TO DAMAGE YOUR CHAIN, use an old one or buy a clutch tool, IT'S YOUR CHOICE!) To lock the crank, stuff cloth or leather between the balancer gears (official yamaha manual method) & make sure all 3 dots are inline when you reassemble. Before you attach the clutch basket, you might like to file down any notches in it. It might take 2 or 3 attempts @ replacing the clutch cover to get the clutch arm in the right place. Torque settings: Crankshaft nut 85 lbsft Balance shaft nut 43 lbsft Clutch center nut 65 lbsft Good luck Rick Link to comment Share on other sites More sharing options...

xtzrick Posted January 25, 2011 Share Posted January 25, 2011 Glad you're making progress mate 40 euros sounds alot cheaper than an engine. You have one dot (punch mark) on the balance shaft gear & two on the crank gear, as long as you haven't taken the crank gear apart, they will still be inline. Just make sure all three dots point toward each other when you reassemble, pic on page 4-75 in ya manual. Let us know if the inner plate washer has been updated, there are a few more interested parties. Rick Link to comment Share on other sites More sharing options...
