Timing... Normal?

[dreded]

So I was checking valve clearances which seemed to be bang on the minimums but when the "T" is in the inspection window the timing chain pully doesn't line up perfectly with the "Arrow" on the case.. is it ok or do I need to fix it?

we wound need to see the crank gear also

knowing that the "T" is lined up with the arrow isn't enough?

Remember that the crank rotates twice as many times as the cam, per revolution, so even though the "T" might look like it is lined up, it could be a "shade" off. Which would make the cam gear be off, like your pics shows.

So in so many words, yeah it looks normal....

I guess that I could "flare up" somebody, and tell you that the arrow is supposed to point at the bottom of the line. :haha:

well what i was thinking is that even if I moved it one chain link over that would be to far the other way.. I very carefully lines up the "T" though it was dead on

ok so then I have it lined up with the bottom of the line.. PERFECT thanks for the tip I would have totally tried to line it up with the top LOL

It is fine. The Wolverine I just did recently was about the same with a new timing chain and stock gaskets. If I am thinking correctly that would be in the advanced position just slightly and as the chain stretches it will work back towards the mark.

:iagree::iagree:

If the chain stretches, even enough to notice with the eye and not a degree wheel, wouldn't the pic shown, actually have the cam gear a little farther off, in the same direction it is, already?

(Meaning the cam gear would be farther rotated to the clockwise position.)

And this is still rotating the crank in the direction of operation.

"Advancing" it is in the opposite direction, of center, as to what is shown.

 

[Rhyno]

Uh-oh..... let the arguments begin.........:haha:

 

['00 WO-YA!]

I've yet to see one line up just right. You'd really need an adjustable cam gear & a degree wheel & proper cam timing spec to get it perfect.

 

[dreded]

now i suppose the real question is when checking the valves should I lineup the line in the picture or the "T" in the inspection window?

 

[Gen1Pat]

Advancing is in the opposite direction. Because the crank runs in the counterclockwise direction so does the cam. So if the cam is set clockwise of center it is retarded, counterclockwise of center is advanced. Whenever you install a vito's +4 key you are turning the flywheel counterclockwise on the crank 4 degrees to advance the ignition timing. Same principal applies to the cam. Mine is just slightly more advanced of center becuase of the decked head and thinner gaskets. Timing marks very seldom line up 100%.

T in the inspection window. One or the other Will be off on these things w/o have an adjustable setup.

The rockers need to be on the "Base" of the Camshaft. The base is where there isn't any lift.

Uh-oh..... let the arguments begin.........:haha:

I couldn't begin to argue on this one because I don't know. If we were talking an automotive engine, I could tell you because I degree cams on them on a daily basis. I have never done one on a Warrior or any other ATV so I don't know. I think where I am getting messed up is engine rotation. On an auto engine if you are looking at a the front, the rotation is clockwise. On the Warrior it is the opposite right?

You are correct. The typical Auto engine (except, maybe a few weird/exotic ones) rotates, viewed from the front, at the crank, clockwise.

The Warrior engine, and most motorcycle engines, with a few exceptions, rotate towards the front of the bike, or viewed from the left side, counterclockwise, at the crank.

I don't know anything about Husabergs but because of their engine orientation, I'd suspect that the rotation is in the opposite direction of other motorcycle engines.

The "Joke" or Smart@ss comment of "let the arguments begin," wasn't directed at anyone specific. :tup:

It was a general invite..... There's been a few of "them," happening lately.....

Here's the motor that I was talking about.....
