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

[@getoutside8202]

Thank you for your content tasks like this can be a lil daunting. With clear concise instructions like this it helps.

[@kasperrasmussen7929]

When you used the thing to hold the magnet 😂 "Left no marks..... that wasn't their before" fantastic And thank you so much for the helpful videos you make. I have problems to start, have changed so many parts, now i think it is my decompression valve/pin The little thing to realise pressure when starting

[@AdamUrbanski-on9kq]

Your video helped me a lot with this engine but I am afraid you might have done mistake fitting tenioner before head cover. This engine has camshaft positioned by head cover and in this scenario, right side of camshaft could have been lifted during tenionser installing , so putting head cover may lead to overtensioning chain.

[@gamepower69.]

Is a torch wrench a must because ive been avoiding buying one for awhile now

[@timbarbee9421]

Excellent video. I have a Massimo 500 that I am getting ready to get into. It cut off the other day. When I try to crank it turns real fast. I removed the side plate on the head yesterday and turned key. Timing sprocket didn't turn. What do you think? Thanks.

[@Hunters_Mechanics]

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!

[@zachburr2219]

My magneto and starter gear are both in good condition but after it has been torqued the starter gear has the smallest amount of in and out play. Must be the washer in between the starter gear and timing chain gear is wore? Should a guy replace the washer or could it be something else?

[@Hunters_Mechanics]

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

[@JessieGarcia-or2xh]

Where did you get the cam chain?

[@SamsonMotlhatlhedi]

How about the gear, is it in a neutral?

[@justinbeauchamp6236]

Mine didn't have a needle bearing under starter clutch, is that ok kinda looks like a copper bushing pressed into the starter gear or something, what's your input on that

[@Hunters_Mechanics]

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

[@Hunters_Mechanics]

Jesus thats a link and a half 😂

[@gamepower69.]

hi, my chain seems like it'll be too tight when on is that normal or ok.

[@adams12329]

should of set cam before you put cover on...the rest is great and a grest help for me with the bottom end...

[@Kevin_Yagoonie]

10:04 what's the purpose of that dowel pin? Im missing it. I didn't realize it until I put it all back together. Can I go without it?

[@Hunters_Mechanics]

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

[@Kevin_Yagoonie]

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

[@bryantblackwell1339]

Bro do you have a video of replacing the pivot bearings in the rear swing arm? I've done them 3 times now and every time it's still sloppy... I don't get it. I've got the pdf for working on it but it's jut not right somehow and your videos are great plz share what you got lol

[@Hunters_Mechanics]

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

[@bryantblackwell1339]

​@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?

[@Hunters_Mechanics]

@@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

[@bryantblackwell1339]

@@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!!

[@realtimez597]

To replace the timing chain can I do it easily still without removing the engine? 2003 660

[@Hunters_Mechanics]

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

[@Yng_Gaell]

How do you know the Eye on the magnet is lined up with the engine when trying to get top dead center does it just fix it’s self?

[@Hunters_Mechanics]

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

[@juandrfl]

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.

[@Hunters_Mechanics]

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

[@NittyOnTheBeat]

Hey bro how do I take the case off the flywheel ?

[@Hunters_Mechanics]

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

[@rickrob7380]

I have a question about position of the piston, its called top dead center but when you get everything done and lined up the piston is half way up or is it just mine?

[@Hunters_Mechanics]

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

[@rickrob7380]

@@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?

[@Hunters_Mechanics]

@@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

[@rickrob7380]

@@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

[@Hunters_Mechanics]

@@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 [e-mail] , id rather give a quick look rather than make you do work when you don't need to

[@timrogers9440]

My fly wheel and the magneto part came apart how do I get them back together?

[@gamepower69.]

you dont gotta scrap it

[@FPVSlacker]

Finished my rebuild. Leaving for a riding trip tomorrow. I did resurface the Niche cylinder and I used OEM gaskets. Cross fingers. Here's a video if it running. This was the 3rd heat cycle of the motor. kzbin.info/www/bejne/aKfFeHh-ftNgZq8

[@normanminer6165]

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

[@FPVSlacker]

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

[@ktr78130]

Is moose racing gaskets good quality ?

[@Hunters_Mechanics]

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

[@timrogers9440]

What's happen if the fly wheel don't just slide on there

[@Hunters_Mechanics]

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!

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

[@Hunters_Mechanics]

@@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

[@johnminyard1054]

The rhino 660 motor is not the same as raptor

[@jzsquad6866]

It has three skits on the flywheel .. idk which one to believe in

[@bryantblackwell1339]

So if im hearing some timing chain noise can i try this meathod i seen of losening the two outer bolts on the timing chain tensioner until i hear a click then tighten them? Will this hurt my valves or something?
