Been trying tonight to shift this bolt on an 1800k without success, despite using 3ft bar on socket handle. Before I start using more 'persuasive' methods thought I'd better check that it IS a R/H thread - can anybody confirm?

Geoff.

It's a normal RH thread and you need a lot of grunt to get it off - i.e. an impact driver.
(The 12 volt ones out of machine mart work if nothing else is available )

That was quick! Thanks guys, look like I'll have to get angry with it tomorrow.

I came across one recently that had Loctite on it, had to get the torch on it (welding not maglite!)

Yup, pretty much every bolt on this engine is smothered in a blue/green coloured locking compound. Looks like this is the first stripdown, so I reckon they must have had a 50 gallon drum of it at the MG/Rover plant

1/2 impact wrench would make short work

They usually come off without any trouble.


On these engines its essential to use loctite on this and the cam sprocket bolts when building back up. These pulleys/sprockets are key less so also put the pulley back on and check there is no float on the D flat of the crank.

Also check the condition of the camshaft roll pins -- replace if unsure.

Said bolt finally succumbed today after applying a bit of heat, beating the hell out of it with the impact driver, and then a further attack with the 3ft bar finally did the trick. Thanks for the suggestions guys, BT your comments have been duly noted.

Make sure it is nice & tight when you refit it as they are prone to coming loose if undertightened.
It would make sense for them to be L/H thread then they would self tighten
