Just for the hell of it flywheel and starter clutch 👍great video man
Good stuff man 💯
Question, i am new to the atv world. I recently had a 02 660 grizzly come included with my house purchase. Upon driving it.....it felt like the timing chain was slapping....was also having issues switching it into gear when on. I could switch it before turning it on, but it would be stuck in that gear. Also, please note,I recently changed the carboerater. So I have no idea if the clutch is not engaging, or if the time chain broke, or is just off by alot. Any help would be great
What sits on the needle baring thats on the shaft
I’ve watched your series on the 660 but missed why you are tearing it down again.
I have a cracked jug on mine as well.
Did you have any more problems related to the jug after you used the helicoil to fix the threads?
I’m about to tear mine down and expect to find the previous owner put the short bolt in the front but want to know if you think the helicoil is a good solution if the root cause of a cracked jug is indeed damaged threads on the lower case.
Great videos by the way, love all the Intel!
Tbh im moreso tearing it down for youtube purposes but also am curious to see what ill find in the bottom, so far I have found a but of CHUNKS of metal in a few places, bent shift shaft, and my oil strainer just clogged will all kinds of crap so that'll be a fun time replacing all of that
I have yet to have any problems with it but can assure that apparently everyone is against using a helicoil over a timersert (or however its spelled), ive yet to have mine come out but oml does it scare me when I put my bolt in because it gets tight, then loose, then tight, then loose then it'll torque down to spec. I honestly have no other clue what could have caused a cracked jug other than the short bolt issue or something flying apart on the inside
@Jake Propst that's pretty hard to diagnose and even harder to replace if it is, how did you come about that it might be that bearing?
Great video, do you have a list of all the parts you needed to do the timing chain?
I mean really all the parts you'd need is just a new chain, stator cover gasket, and new o-rings for the dowel pins, that is if nothing else is broke or worn lol
@@Hunters_Mechanics thank you for the quick reply. Did the valves on my 05 and there is still a pretty loud ticking noise which other videos have suggested to be the timing chain. Gonna order the parts and hope that’s all that’s wrong.
Are there gaskets that need to be replaced on the 660 engine when doing the timming chain
The starter cover, the stator cover (which is the large cover you take off) and you'll have to use gasket maker for the valve cover. I hope to get part 2 video'ed this weekend and show what needs to be replaced
currently int the process of doing my 2004 raptor 660
Let me know if you have any questions!
@@Hunters_Mechanics Mine did not have a washer behind the needle bearings on the Crank shaft and I can not find on the parts diagram where it calls for one, do you have a close-up shot of that area? it looks like a washer is on the timing chain gear there but it does not come off.
@@Hunters_Mechanics Im talking about the washer you remove at 9:45 in your Video BTW
@@justinnorton4308 I won't be able to take any new pictures till this weekend, but this is the oem parts list that has the washer if that helps drive.google.com/file/d/1w5gR33Y-DcvEpQzvBjNN0RyVNynEWvOZ/view?usp=sharing
Part Number: 90201-286K9-00
@@Hunters_Mechanics Awesome!!! Thanks brother. Part number is what I needed
Ive tried timing mine a few times and setting the valves it sounds like it wants to start but it won't. Idk what I'm doing wrong. timing is on according to marks.
Smell any gas while trying to start? Does it hit any when its turning over? Spark plug look good?
can you show me all the wiring that leads up to the battery my son took it all apart
I have my wiring completely different around the battery because I have a truck starter relay rather than the stock one, as far as I'm concerned if nothing was changed, should be easy enough to have the short cable going to the relay from the positive terminal, then a singular cable running from the relay to the top of the starter, then the ground from the batter leads to a bolt in the stator cover. The relay has a 4 pin connector that doesn't fit anything else and the cdi has 3 connectors that only fit it. If my wiring my was untouched then I would definitely send a photo but I dont want to confuse you more with mime
Do you need to separate cam from sprocket to install
You do not, all of the top end timing is explained in my timing tutorial on my channel and it shows installing the cam without taking off the gear
@@Hunters_Mechanics I saw the video and thats good one less headache as I am new to this overhead cam. I rebuilt my honda fourtrax420 top end and it was simple.
@@shawnmcnulty1549 surpringly enough, every single vehicle that came into my vocational center when I was still in school was a Yamaha and they're all pretty much the same top end design so I got accustomed to them quick. I have yet to get into a Honda
Yeah I have a question my 660 yamaha raptor wont engage second gear I change the cluth already all the gears are good but except the second gear
Can it skip 2 and hit 3 or any gears above it?
@@Hunters_Mechanics yes it does all the gears are ok just the second gear
I put in 1 gear I'm driving and the moment I hit secound it slips but kind that wants to go do I hit 3 gear and 4 and 5th all are smooth except 2 gear
@@albertocelaya8685 I don't know what all was inspected but did you check the shift drum for any excessive wear in the grooves, shift forks look worn? Check the bearings for any excessive wear? I'd assume that if the other gears are fine the clutch should be fine
What is the pattern for the clutch plates on a 660 yamaha raptor 2001 ...
How long did you get with that Niche cylinder?????
I've only gotten 20 hours on it and my fan went out and thermostat stuck closed and blew my head gasket 😒 it still looks brand new and no wear pretty much at all, still plan on using it after I get the bottom end back together
I can’t take off the fly weel I tested all I have in my possession I even made a flyweel remover, did I forget something
Tried applying some heat to the fly wheel to make it easier to come off?
@@Hunters_Mechanics yes right now I tried to heat it with a blowtorch for like 3 minutes was hot to touch but nothing happened
@@Hunters_Mechanics even tried with tapping it after heating and doing som puller works
@@ktr78130 I know its a horrible video but ua-cam.com/video/c8kIyG7trqQ/v-deo.html at time 4:50, have you tried hitting it with a hard rubber mallet like that one one the outside edges with puller tension on it?
I hope that you didn't remove the engine just to change the timing chain/ set the timing
I am rebuilding the bottom end, just decided to make this video while I had it out and while I am waiting on parts
Jammies screw drivers between machined surfaces.... Rookie shit
