Cam sprocket onto cam shaft.

Sometimes you need to hold your tounge just so, say a chant and the sprocket magically mounts in position. Generally happens after a good night sleep after wasting a whole day on the problem.

The Haynes manual says that when you're putting the tensioner in you pull it up and lock it into place to remove tension. I removed the head and the tensioner can be pushed up and down by hand with the nut in place. Something's not right. I'll take a closer look tomorrow.

[Bonez]

Was the upper bolt and o'ring fitted?

[Magua]

It was indeed.

Idea. Feeding rope beneath the tensioner and pulling up on it to reduce its effect upon the chain. We'll see how it works.

Hey that was my idea you idea thief!

[Magua]

I don't know what you're talking about.

update ?

If the tensioner has both a 10 mm head bolt (that comes out) and a 14 mm locknut then the secret is a 3 mm screw threaded into the inner part and then you can pull on it to allow a small amount of tension relief.
Then when all is in place let the tension off and tighten the back nut according to the torque spec.
PS , you may have to tap the 3 mm screw a few times to free the inner rod if it is semi siezed and a bit of CRC wont hurt.

You bloody rough bastard . use a bloody shovel and do it once ..... properly

I went over today (not just because I'm an exceptionally nice guy, but also to use a chain splitter that's there) and we scratched our heads and puzzled about it and managed to get it on.

Even with the tensioner fully backed off, it's still not going to go on with hands alone. So I got frustrated and rotated the engine 90 degrees around -- that way it was possible to get one bolt-hole lined up, but not the whole sprocket up onto the shoulder. G-clamp to hold one side on the shoulder, then crank the engine back over to TDC and it pulled itself on there.

I think Mr Magua is putting the whole lot back together as we speak.

sweeeet! get my car bacK!

What? What's wrong with that lol? Nothing was resting on any bearing surfaces or under any undue tension. The only thing that was being leaned on was the camchain itself, which needs to back off that far to run the engine anyway.
