Home made Valve adjustment wrench info - PeachParts Mercedes-Benz Forum

These are the valve adjusting wrenches that I made. I started with two cheep 14mm wrenches. I cut the box end off the wrenches and bent them then brazed flat stock to them. To make the third wrench I cut 1/4" off a 30mm socket then brazed that to 1/8" flat stock and then cut a 20mm slot in the end.
Hope this helps someone

Total cost was less than $10 and I have been using them for about 2 years with no problems.

Oh yea, you want the two wrenches to nest so that the upper one can pass over the lower one when you are turning them.
I just added some info on the valve spring retainer wrench. With these dimensions and the photo it should make sense.

Totally state of the art! Thank you Phil for setting the standard by which all valve adjustment wrenches oughta be judged.

Well done!

Nicely done Phil. While I too have bent my own wrenches I had never thought to make a "hold down" wrench from a socket. Unfortunately when I down load the file it's blank. Has anyone else had this problem? I get the pop-up massage "Unable to load graphics conversion filter" for windows 97. Could you try a e-mail or ...someone know a fix.
Thanks in advance

I just added an easier to use copy of the dimensions.

Thank you Phil -
I've been working so I have not visited in awhile. How nice to log -on and not have to look for this post. I'm off for the next few days so I'll try to make the "nut holder"

Thanks again and have a great day

When I was in my teens, I worked at a Porsche/Audi dealer washing cars.

I got to watch the mechanics work on cars too. Some of them had their own specially made tools. As I looked at the wrenches above, it reminded me of some of the tools they made for special situations.

I've always wonderd this, but have never asked anyone. I'm sure there is a simple answer....

When making the tool, why was brazing used instead of welding?

I brazed because I felt it would be strong enough and more importantly I had a torch but no arc welder at the time and it has worked fine and I like gas welding better.

Fantastic, Phil!!! You have made such a tremendous contribution that I hope everybody in this forum is going to realize...
I have seen similar wrenches sold for $89 and $99... Your instructions here make it accessible to all for just a few bucks... I already have old stuff I'll be making the wrenches from... it's going to cost me maybe 2 or 3 bucks altogether...

Thanks you so much!!!

Should this be a sticky?

vstech · #11 03-13-2007, 02:46 PM

if not a stickey, perhaps the OP could rename the title of the thread to valve-wrench so the one word search we have will always find it.
John
heh, never mind, my post triggers the search!

Done on the title but it doesn't show that way on the forum list, any idea how to change that?

vstech · #13 03-14-2007, 12:10 AM

I don't think it can be changed once replies have been posted... and it's not important anyway, due to my post having the hyphen in it, a search for "valve-wrench" always turns up this thread!

Do you find it nice that the heads point different directions? I have the factory tools, and I organized the factory tool group buy. Its a very nice job, sometimes I make tools too, when I am in a bind.

These are best looking out of many that people have shown.

By having the heads pointing in different directions it can make it easier to get on to the nuts on the valve stems but remember the valves are floating so you can turn the whole thing a bit for better access if necessary.

A note on the third wrench - After the first time I adjusted the valves on my car I have not had to use this wrench again.
