ATV Timing Chain Replacement Part 2. (Raptor 660 Used) 

Could have broke the chain or it had too much slack that it disconnected from the crank sprocket that drives the timing chain. Either way sounds like you need to open it up and get it fixed!

Did you place the washer at 2:56 as well? That one should eliminate the play. The washers shouldn''t wear down at all, especially to cause a noticeable play

Yes you can, I just had mine out since I am rebuilding the bottom end

Absolutely, it's just to help hold the gasket while you assemble that starter cover

@@Hunters_Mechanics awesome thank you so much for the quick reply. I subscribed 👍

Is it just a bare material like this? www.bing.com/images/search?view=detailV2&ccid=T%2FXPFIC3&id=E8CD3D9DC4F303F5C60D1354DB137627C14FF221&thid=OIP.T_XPFIC3BR2e6tZLSe9CqgHaEX&mediaurl=https%3A%2F%2Fwww.sss-racing.co.za%2Fcontent%2Fimages%2Fthumbs%2F0002251_starter-clutch-raptor-660.jpeg&cdnurl=https%3A%2F%2Fth.bing.com%2Fth%2Fid%2FR.4ff5cf1480b7051d9eead64b49ef42aa%3Frik%3DIfJPwSd2E9tUEw%26pid%3DImgRaw%26r%3D0%26sres%3D1%26sresct%3D1&exph=453&expw=767&q=raptor+660+starter+clutch&simid=608022637754916289&form=IRPRST&ck=E2152AEB72523CF58D94C4F2EB545173&selectedindex=2&pc=EMMX01&ajaxhist=0&ajaxserp=0&vt=4&sim=11

Jesus thats a link and a half 😂

you dont gotta scrap it

Since the magnet sits on a key, the magneto will always show the position of the crank, so when the magneto is lined with the 'I", the piston will always be TDC

Hey dumb question. I think I already have the answer but I rather be safe than sorry. The magnet has a few markings. H l So I want to be aligned with the straight line all the way on the right (l). Not the (H)? Thanks for ur videos very helpful.

@@juandrfl that is correct, the "I" and the case should be aligned, not the H

I rebuild mine years ago and its still sloppy on mine too, but my swing arm is broke where the bushings sit lol I might buy a used one soon and do a video overhauling the entire suspension

​@Hunters_Mechanics man that would be great! I'm worried mine broke too but I didn't keep track of the order inwhich I took it apart like n idiot lol. But the side with the thrust bearing I think it's called on the chain side. I just keep crushing them washers. When I take it apart they aren't flat Amy more they are more bowl shaped what am I doing wrong?

@@bryantblackwell1339 I installed mine only once so I can't help on why it causes that, if yours is doing, I almost guarantee mine did too, when I do tear mine back down to replace it, I'll mention if I find a root cause for it

@@Hunters_Mechanics right on man thanks for being so quick to respond as well. i appreciate that! so upon tearing mine apart for idk 4th time or better lol, i i got a little more meticulous with it. i had pressed the bearings and bushings in but i didnt pres the thrust bearing i think its called or crush bearing lol not sure but the washers and bearing that they sandwich on the chain side. i pressed all that in and its night and day the difference! im still having some slight play from something when i get going down the road it wants to pull just a bit one way or the other every so often if that makes sense. so all the goofy pulling wasnt due just to the rear end but i think its the bearings in my a arms. food for thought is all i guess. love the content though im thinking its coming in for the winter and tore down to the frame and gone through so your videos will be verry useful then as well thanks man!!

Watch part 1, it goes in detail on how to get it off

Sometimes it can be rough getting it on I know, but as long as you are sure that it is sitting on the Key and you have it torqued to spec you should be alright!

I've never used them before so I wouldn't know

I hope it works! But I would go back to OEM cylinder. They sell cheap on eBay.

@@normanminer6165 It failed. Cylinder liner dropped in the casting and head gasket failed. I've since rebuilt it with good parts.

You may have your cam installed 90° off, that would cause it to look like its at top dead center but in reality the piston is only half way to TDC. Unless you mean you have the bottom end gear lined up with the line in the case and its at halfway to TDC, then something is wrong lol let me know more details

@@Hunters_Mechanics The bottom is lined up at the bottom, and the cam is in line with the marks on the cam shaft has th holes up with the compression bolt on the side just as in your video but if I stick a screwdriver or wire to touch the piston its mid stroke Or in the middle . Should I rotate the crank shaft a few more rotations?

@@rickrob7380 are you for sure that the piston isn't at top dead center since the spark plug hole is so deep itself? If the bottom is line up with the marking inside the case or the slit on the case, that has to mean its at top dead center. Unless there's the off chance that your magneto is not sitting on the key and has rotated but I don't know what you're lining up at the bottom

@@Hunters_Mechanics i was thinking the same thing, I can set it on the line and put the wire on the piston and turn the crank shaft and then piston will push it out. And it will be past the line by then. I will pull it back apart tonight and let you know if you would like

@@rickrob7380 can you send me pictures of what you're lining up on the bottom end and the top end at TDC to my email bacon626262@gmail.com , id rather give a quick look rather than make you do work when you don't need to

@@Hunters_Mechanics thanks I brought, but one question how tight do I squeeze it because too tight I think would break it

@@gamepower69. If anything it would just scratch the magneto some, It's pretty hard to "over-tighten" it lol but it's also gotta be snug enough to not slip when torquing that nut down
