Flywheel nut removal issues

Post by Biglozzer »

Ok so all day today I've been trying to remove the flywheel nut on my 2276cc engine. First easy issue was it isn't a standard 36mm nut. Mine is a 38mm which I've used a 1 1/2" socket that fits.
It's seized on there solid.
I've used a pry bar and a SNAP ON torque multiplier x 4 which would normally shift anything. No joy
I've tried a 6 foot scaffold pole over the pry bar and it's lifted the engine plus one adult off the floor. No joy.
I'm assuming the original engine builder used lock seal on the nut as some do and it's literally 13 years later glued it on.

I've got a worn leaking main seal behind it so need it off.

Any better ideas?
I'm thinking of heating it to burn off the lock tight. I don't possess a oxy set up though.

Next step is two more mates to hang off 6 foot pole and no doubt snap the pry bar!

Been a long wasted day. So any help appreciated
Thanks.

feel your pain. can only suggest heating as you mention. but when hot have the scaffold bar on it under tension with another person, and then hitting the bar with a sledge hammer to try and shock it off :(

Heat should soften the thread lock, if that's the cause.

Or take the engine and the socket to a tyre shop and ask them to put the air gun on it. Preferably a place that does truck tyres as they'll have monster guns.

I chiselled my old one off in the end. Took about an hour and obviously totally screwed the nut but it worked

We'll update for today. Brand new pry bar snapped. Heat made no difference. So arranging for a mobile plant machinery guy to come out in week to use heavy duty air tools and try that.

You need to borrow a torque meister.

I have one of these

If there's something to lever against i.e. somewhere for the bit with the holes in to jam against (a nut or a socket on a nut) this should take it off. It's a 64x multiplier.
Made short work of my hub nut that bent a 40inch 3/4" breaker bar with me jumping up and down on the end.

Well it's off! My mate in the Royal Engineers let me borrow a 4 foot very heavy duty breaker bar used on tanks! It still needed the 6 foot scaffold pole over top but with two of us hanging off it it gave in with a loud snap. As suspected a liberal application of lock tight was dried solid and present. So happy days. thanks to those who gave advice.

How on earth did you hold the engine still?

Best way to do this is to bolt a long steel flat bar to the flywheel using the clutch bolts, resting it on the ground. I have a thick bar drilled for clutch bolts, wheel nuts etc. Makes the job much safer and easier. Does the rear hub nuts as well without any dramas.
