Cilinderhead turns roughly HELP

[Rallye20vt]

I am in building an new engine.
New pists bored engine and stuff like that.

Butt my cams are turning pretty rough so i can feel.

How much Torque must is tighten the nuts ?

I did it by hand.
Can i have damaged the bearings now ???

Please lett me know asap/.

Gulp...

You might have put the cam caps on the wrong way round?

[Rallye20vt]

How did you mean that ??

There are 2 rings that needs to be at a special point it cant be done wrong is it ??

[Flat on my back]

Can you just see the edge at the join...

That means its on the wrong way round.

[Rallye20vt]

There are numbers on it.

If you loook closely i almost is impossible to do it wrong.

By the rings i meant if you look at the chain on the cams.
They have to be in one line with the head.
Accrosing each other


I did do it wrong in the beginning,
i but the bearings wrong.

i have put 6 in number 9 and te other way around,
then it was stuck,

I took a bette look and saw that it was wrong swithced it around and it was better.
But i think it needs to be smoother than wat it is know.

Can i have damaged the bearings by puthing them at the wrong number order in the beginning\.
Or by thighten them to much.
I didnt have a Torque wrench thats why ive done it by hand,.

Torque setting for the bearing cap nuts is only 15Nm so it would be very easy to over torque is your doing it by hand.

[Rallye20vt]

Would this damage the bearings ?

Ive heard sombody said its from alu if over torqued how can is solve this.

Buy knew cam bearings ?

I have to put some pressure when bolting down, to put the valve rocker in. is that normal ?

Sorry for my bad english

Its impossible to say if you've damaged the caps without knowing what torque you have applied. But stop until you get a torque wrench.

If you guess on assembling the engine it simply wont last.

[Rallye20vt]

Yeah its pretty stuped of me .

The other bolts i used a torque wrench but the garage i borrod it from need it back,


Tomorow i put the cams out and put them back on torque measruments.

Maybe then its over and turn moore smooth.
I hope so.

You can not over-torque these studs..... they simply snap when you apply much more then 15Nm. That happend to me 3x before.....

[Rallye20vt]

I have rebolted evertything.

Put it back and tighten it in the right order at 15 nm each.

It seems to be loosent up a bit.

But is it normal that it has one point where it turns a bit more difficult . ( looks like compression ore something )

I turned it by hand at the crankpoelie without spark plugs.

[Bram]

Yes, this is normal.
