Crank not rotating

[alexdecker]

Just connected to the halves of the bottom end. My crank seems to be stuck though. Checked the gears before installing and they were fine.

Is it supposed to be able to rotate free at this point?

Something is put togerher wrong, should turn easy

[alexdecker]

It happens when I torque the 10 main bolts down. 17 foot pound is my spec. Why is this??

[alexdecker]

Just went down to 14 foot pound. Still seizes when I tighten.

Wrong shell in wrong location?

Check nothing under the shell making it stand prouder.

My thoughts.
1.Is it in neutral.
2.Is the cam chain free.
3.Did you Plastigauge the mains.
4.Are the conrods free.

[alexdecker]

Everything is free. I didn’t plastic gauge, as I marked the location of each bearing and put them back in the same place.

How big was the hammer you used to remove the rotor? ......
I'm scared of you.

You did put the shells into the cases with cases and back of shells dry didnt you,mixing up shells would not normally lock it up, i have built with all tightest shells before now with no problem.
Primary shaft needs to be fitted and cam chain free but should turn by hand.
You havent tried to miss match cases?

Crank seal located correctly?

[Oddjob]

A black in a yellow location might lock it Bryan but I was more thinking of something behind the shell making it bind onto the crank.

I assume the upper half case was upside down when you started assembly. Did the Crank rock freely when sat in the Crank mains with assembly lube applied? I am assuming it not significantly different to a 400/4. I
Can the Crank be fitted in the wrong way round.

Oh god, I hope I didn’t do what you are referring to!

I did exactly that. Pretty sure I mounted it the right way. And yes, it moved freely.

I only lubricated the crank contact side of the shells. I fear that the crank might have gotten bent when I put the hammer to the rotor puller to get the rotor off.

Still - I didn’t have the crank in a vice when I did that, so it could move freely, and the rotor puller and rotor contact point seems too small to be able to bent the crank like that. But it’s the only possible thing I can think of happened. Everything else is in its right place. When I torque it down with my drill, it still rotated freely. But with the torque wrench it seizes up 😕
