Fork drain 13 mm tool?

I'm having a hard time finding a wrench that will allow me to remove the 13 mm nut while holding the 4 mm Allen.

I can use a socket in a pair of vise grips, is there a better way.

I thought I found the right wrench but the offset isn't enough.

Thanks.

I will have to weld up a socket like that next. I just drained my forks yesterday to replace the seals. I used vise grips on the socket like you said and it worked just fine.

I bought an individual 3/8" drive 13 mm socket then used a grinder to make flats so that a 17mm end wrench fits the end. The socket is then a 'custom BMW special tool' and put in a labeled zip lock bag with the BMW motorcycle tools.

The flats are ground at the drive end of the socket the height of the wrench. Gravity holds the socket to the wrench. Good luck!

Or just grind a relief on the backside of the box-end to give clearance. It'll weaken it a tad, but how much torque is needed from a 13mm?

I bought a Snap-On wrench that works perfect just for that job.

Craftsman offset box end wrench (bought back in 1970) works great with no mods.

Just get a cheap 13mm offset wrench from your local auto parts store. The cheaper the better. The cheap ones tend have a skinnier "elbow".

Grinding flats on a socket works but can be kind of a hassle because you have to hold the socket, wrench and allen key. You'll probably end up dropping one or more pieces more than once.

Socket and A pairof vice grips works every time for me.

How often do you do this in the lifetime of your bike, once every couple of years I would guess, there might be better things to spend your tool budget on!

He who dies when his over full Craftsman toolbox falls on him during an earthquake... not so much.
