Can't Loosen Drive Shaft Bolts

[Anonymous]

I'm removing the engine from one of my 1100GLZ's and have run into a bit of a problem. I can't loosen the drive shaft bolts. I have pulled hard as I can and not one of them is budging. I don't have a very long wrench, so I'm thinking of buying a longer one so I can get more leverage. I'm also thinking of trying some Aero Kroil and hope it won't have an adverse effect on the lubrication. I'm wondering if any of you have any suggestions.

hammer! or use another wrench looped with the first for leverage, that is what I had to do.
those bolts are pretty tight, be carefull, when they come loose, they come all the way loose in a instant, easy to smash fingers.

They will be dificult to break loose. They are installed with a thread locker & should be reinstalled with same (locktight) Double the wrench as sugested

Thanks. I'm a bit concerned about breaking the bolt (though I do have a spare drive shaft). I've had enough broken bolts.

Impact driver? Mine has never failed me.

Cheater Pipe!

Just get a bigass (2-4') pipe that barely fits over the handle of your wrench, then you'll have some vicious torque at your disposal.

That was the only way we were able to get the front sprocket off my buddy's bandit.

Swearing helps a bunch too.

You just need to get the bolt to move a bit to break the grip of the thread lock compound.

Place a box end wrench (ring spanner, if you live on a damp island just north of France) on the bolt and tap the end with a hammer to get things started. Try to find a six point wrench or at least use a good quality 12 point wrench.

It will take a bit of impact, but try to work up to the amount of force needed gradually so you reduce the risk of stripping the wrench.

Once they break free, they'll come out easily.

Hard to loosen bolts

Hello
The safest way to loosen bolts that have locktight on them is to use a hand held impact screwdriver that u can reove the head and expose the socket conector and mount an impact socket. Hit the end with a big hammer as you turn the handle. Make sure the driver is n the remove mode, the end turns on or off. allowing the user to choose to use the tool to tighten or remove tight screws or bolts.
This too can be purchased at any hardware store for under $10.00.

Good luck ! Archie

There is no way to access those particular bolts with an impact driver, so that advice is fairly useless in this case. On my 850, I couldn't even get a socket in there -- only a wrench.

We're talking about four fairly small bolts (8mm or 10mm thread, I think) that hold the driveshaft flange to the gearbox output flange. We are NOT talking about the giant front sprocket nut familiar to all you neanderthals with chain drive. :twisted:

Once the Lok-Tite bond is broken, you can remove the bolts with your fingers.

One caution I might mention is that you need to secure the rear wheel to prevent the driveshaft moving suddenly when you start to apply force. Putting the bike in gear is not enough!
