Cam chain removal?

[Honda#4]

So in order to get the cam chain out so I can put in a CRF one I have to take off the whole clutch basket? or do I just have to take off the oil pump gears?

Then it says that the clutch nut is staked? whats that mean?

[drew416ex]

Yes you have to take all of that off. You will notice a spot on the nut where it is staked. After being torqued it is hit with a punch or something bening the lip on it so it wont come off. You have to grind out this part to get the nut off. A dremmel or air grinder with a small grinding tool works great.

then after you grind it do you repunch it so the nut dont fall offor what?

[j450rking]

yes if you can

I just went through the same process. It seemed like a lot of work just to change the little cam chain, but it wasn't overly difficult. Fortunately, I was able to repunch the clutch nut again. Good luck!

[Honda#4]

Could you just take a file to it or is it to much for that? What if you cant re punch it then what?

Is the nut a reverse threaded nut?

[dustin_j]

The nut is right hand thread, and I just torqued it a little past the area I ground off. You would be filing for a long time; I'd recommend a dremel!

Ok J/W. I got my Cam and my gaskets today but I have to wait a bit till everything clears on my credit card then she's getting riped apart.

I dont like over or under torquing anything. The nut is just $4. Just get a new one.

Yea I think your righ i'll just do that just so im safe.


Anyone by chance have a real pic of it? looks so blury in the manual. Thanks

[dustin_j]

Yeah that'd be a good idea. A fancy clutch holder tool would be cool too (you could easily make one with a vice grip) would be nice too. Smart idea getting info and reading the manual before diving in; I've gotta work on that :ermm:

[Honda#4]

I plan on buying a clutch holder tool also.

I want this to be a one time thing so im reading the manual alot. It doesnt pay to go cheap whenit comes to the motor.

I didn't use a clutch basket holder. I used an impact gun to remove and reinstall the basket and main gear nuts.

[Honda#4]

Hornet, did you put it in a gear so the motor stops or how did you hold it?

[bdtoady22]

i also used an impact to remove mine i put a rag around the clutch basket so it wouldnt cut my hand. i didnt unstake mine it threaded right off with the impact and didnt screw the threads up or any thing. grinding in side of an open motor? i wouldnt recommend it but hey its yours do what you want

[Honda#4]

Well I just ordered my CRF cam chain and a new clutch lock nut. If I screwed up the threads on the shaft i'd be screwed but if the filings get in the motor that aint good either but if I put a rag or towels in there I dont think it will be a problem.

[hornetgod13]

The impact gun took the nut right off. I didn't unstake it either. The quad did not need to be in gear.

when they talk about it beeing staked all it amounts to is this. on the clutch shaft there is a machined groove 1/8 in. wide the nut is basicly flat spotted in to the machined groove to prevent premature looseination (just thought it would add some humor). it is no different than a rocker arm nut on a small block chevy or any thing else for that matter. just prevents it from working loose but isnt impossible to remove. but which ever way you do it it really isnt a bad job. i spent extra time checking out my clutch, tranny shafts and bearings etc.
