Hi;

 

What's the correct way to remove the CamShaft nut, the one that holds the timing gear on?

 

I have removed the Flywheel and split the engine but don't know the best way to stop the Cam from rotating to hold the nut.

 

Is it a 1 and 5/16th Nut?

 

Many thanks

block of wood between crank and block. same as steering wheel nut, crank bolt. hub nuts and big subframe bolts.

I tend to tighten/loosen them while the flywheels still on and lock the ring gear.
If flywheel is off - as nick suggested.

Screwdriver through a hole in the gear and lever on one of the 3 cam plate nuts. Saw it on a minimania video and used that trick ever since.

What he said 

 

Always use the most direct method. Wedging the crank with a block of wood is putting the strain through the timing chain .

Electric rattle gun also works wonders on a tight camshaft nut. And as long as chain is in place you don't need to wedge anything.

 

Because the nut is so thin find it best to use a very close fitting socket.

What size is the nut?

I never over-tighten that nut because of the grief it would give if the thread stripped. I just 'nip' it up, using Loctite and the lock washer.

The only time I had a problem doing this was quite recently when an after-market sprocket had the slot for the key too wide and the sprocket moved slightly on the cam causing a nasty rattling noise which alerted us to the issue.
