Upon re-install of cam?????????

[Fearthepack]

This is the cam and dot location prier to tear down...


Getting ready to install and here is dot location...




cam lobe touching #2 valve bucket



Some guidance is in order....

I'm thinking this maybe no big deal, that big 22 mm nut on the cam itself might be there for fine tuning the cam (aligning the dots)once the caps are torqued down...anyone care to second that?

[LoHo]

Yep, that's what it's for, but don't move it with the sprockets attached. Also, pay attention to the little tabs on the screw holes of the sprockets so that both are on top when the arrow and cam dot are aligned.

[Fearthepack]

When i rotate the cam and align the marks will it stay in place or will it rotate back?

[Orange4]

Whoa. That is definitely one tooth out. Don't move the crank. Take the chain off the sprockets, realign the cam dots with a wrench on the cam hex and put the chain back on. Make sure you keep tension on the chain at the intake side while you put the chain on the sprockets. That's the side it pulls from.

Okay, just in-case anything above confused you, follow this:

DON'T MOVE THE CRANK!

Remove the cam chain tensioner and cam bridge. Remove the chain from the sprockets, or at-least one sprocket. Rotate that 22mm hex on the cam and align it with the dot. Make sure the cam sprocket notch is in-line with the dot.

Next, pull the chain off the other cam and align.

Now, pull the slack out of the chain TIGHT from the crank sprocket, and pull over the intake cam. Now pull over the exhaust cam. Insert CCT and cam bridge. Rotate crank by hand a gazillion times to make sure dots align.

Orange4 take a closer look the cam caps are't even installed or sprockets... the cam is just sitting there

[Fearthepack]

So moving forward I can install cam caps and torque the bolts then rotate the cam to aligns the marks and they will stay aligned while I move onto the sprockets and chain?

[DiverRay]

YES, or very close to it. What little bit it MAY move is easily put back when you install the chain.

[Bartman]

And make sure that you torque with the correct spec!

7.2 cam 14.5 sprockets

Thanks guys

Just an FYI, unless your torque wrench is sensitive enough at that low of a torque spec, I'd take Steve's recommendation and use an inch pound torque wrench. It's amazing how little past hand-tight those cam caps need to be.

I hope I'm not too late with this news.........



I'm shocked that no one noticed what's wrong with this photo.
To fit the cams, you have to have the crank pointer at the "T" mark! Not the "C" mark.
The T is the mark for top dead centre.
The C is the mark for adjustment of the cam chain tensioner.

Lift the cams back out, rotate the motor to the T mark then fit the cams and align the dots and hope that you haven't bent any valves yet.

If you've got a Clymer manual, open to page 66 and read the installation procedure carefully

[IanDMacDonald]

Huh, lol? His pointer is on the "T" mark . . .
