Royal Enfield AVL drive nut removal

Wedgey not worky.

Leaving it in gear with the rear brake locked on, the chains are bowstring-taut and it's not for budging.

Time to buy an impact gun?

Hi Roger, bought myself a 4ft breaker bar, was the only thing I could shift the rear wheel nut and front sprocket on a vfr750,

[Rogerborg]

I don't think I can put enough torque on it to budge it without snapping or damaging the drive chains though. I'm just prevaricating about the bush a bit, I'm pretty sure I'll need to impact gun it.

On that, can anyone recommend an electric gun, or am I better off just biting the bullet (har har) and getting a compressor?

looks like a brass nut that jobbie , how about a bit of heat should warm up faster than the surrounding steel

[Pete.]

Not looks plated, not brass. Might be threadlocked though so getting it hot might help a whole bunch.

OK, I'll go and get some cannisters for my torch. Please continue the discussion in the best BCF traditions.

If it's anything like the front sprocket on my DRZ a 4' breaker bar won't work, I then bought an impact gun for £30 and it came off with two short blasts.

I'd be a bit leery of using heat on anything in situ on an engine
and try an impact gun/ breaker bar/ flogging spanner etc first

OK, heat did nothing except produce clouds of ATF smoke, and Pete was right (you'll be astonished), it's not a brass nut, it's just plated. Or was until I burned it off.

I don't want to snap my drive chain(s) by using a breaker bar, so I'll be impact wrench time. In my head this is more likely to rattle the nut free than to snap the chain, right?

I reckon I'll go with this un as claims up to 450Nm and I prefer mains, unless anyone can suggest something more suitable. 32mm deep impact socket is already ordered.

The drive chain can handle the thuds of an enfield engine, many times a minute, for many years. I doubt you'll snap it with a breaker bar.

Alternatively, use a chain strap (like an oil filter removal tool) or make one with some chain and some manner of bar. Your current method is putting more pressure than I would like on the engine casing.

An impact gun might not get it off. My compressor driven one gets annoying spinny things off usually - like lower cambelt pulleys on cars - but if it's really tight then I need to find a way of locking it and using the big breaker bar.

Have you spoken to Draganfly? There's a couple of dudes there who know a thing or two about Beezers.
Also the Beezer clubs/forums are a bit more specialised than some of the spazed out buffoons on here. 😀
The impact gun will still stress the chain whether you like it or not. 😀
It may be more efficacious/safer to undo the primary chain and lock the teeth directly.
Then get your bar on it.
If you exhausted your efforts with 1/2"drive then may I suggest Bills Tool Store and pick up a 3/4" bar and socket. Even a 3/4" drive ratchet will do it. Then you will have a 3/4" drive ratchet to impress the chicks with.😎

An impact gun is a good thing to have and should remove that without damaging the primary chain. They're also good for removing gorilla tightened wheel nuts and the like.

Hi Roger, I think definately with the chain tensioner out of the way and the chain off , would give you more room to wedge the two drives and not have to worry about breaking/stretching the chain

If you are near brighton rogerborg you can borrow my snapon battery one.

Bit late to the party but have you considered the manual style Hammer Impact Wrench?
I don't find them so friendly to the nut itself, but you already napalmed your current one and this way you have direct control over the impact/torque applied.
Almost every nut and bolt on my shitty bike was seized so I've gotten plenty of practice.

I wedge a folded piece of nylon webbing strap between the sprocket and primary chain to remove the engine sprocket on my bullet. This locks it up solid.

EDIT: There's another way of locking up a sprocket if you can get the chain off one end that's used for removing fixed gear bicycle cogs (which land up EPIC tight). So if you were struggling and can manage to wiggle the chain off the clutch basket then remove it, this ought to work (and at that point, you can use any scabby bit of chain that fits on the sprocket).

Never tried it, it's a thing I've been carrying in my head for if other techniques fail.

I've never heard of anyone breaking a drive chain with a bar on the nut.


Bet nobody else has either.
