Title: Tool - Remove Air Filter
Post by: dante53 on January 19, 2014, 11:25:57

What tools do you use to remove/reinstall BC or WRD air filter? I can't get enough room for ordinary wrenches (230 late IP).

There are some wrenches you can purchase that are very narrow and will fit to remove the air filter.  I don't remember the size, 17 or 19mm, but I took an older wrench I had extra to a grinding wheel to make it narrower.  Worked out fine.

Cycling wrenches are narrow and well built (and not particularly expensive).  They come in a variety of mm sizes, and I have used them for car repair in a number of cases like this (BMW fan clutch removal, for example) where spaces require a narrow tool.

Thanks for the hints. Tomorrow I will look for cycling wrenches. I know at least a couple of places where I should find a complete set.

Dante,

Your W113 should be 19mm (3/4" can be used), latter W113s used 22mm (7/8" can be used).

Didn't notice that you live in Italy......  Careful you don't return home with a nice bike along with the wrench !!

Ciao -- Roger

Mine uses 22 mm, I bought a regular wrench from Harbor Freight and grinded it until it became the same thickness as on the air filter nut. It worked fine.

Hello Dante, These pictures should give you some ideas on how to make your own wrench.  This wrench started life as a 14mm wrench.  After many trips to the bench grinder, it was opened up to 22mm.  Works great.

Check your progress often as you can't go back!

Get used to modifying your tools to do the job.  I miss-place tools a lot so I typically have 2 to 4 of everything, so it doesn't hurt me to cut or grind one.  Have a container of water handy to cool it off.

Grinding down an end wrench, which is what I did is a lot of unnecessary work. Buy a bicycle (what is called a cone wrench here in the US) wrench. Very economical and it works fine. Be sure it has a 19 mm opening.

I rarely open my original MB toolkit, but the original wrench is actually narrow enough for this purpose. It is also short enough to remove the BC - standard wrenches tend to be too long to fit.
