I have a set of Hazet and Hyco wrenches; both are about the same. I also have a set of Arthritic hands, wrists and so on.

Yet, I cannot see comfort as being serious issue during 1 Valve Adjustment.

However, I am a big Fan of Butter.

Either way this thread is about a new source for valve wrenches...

At least you know of the new source, they are made by a trusted member of the forum and they work well.

My set arrived the day after Christmas and they seem to be exactly as
Allan described. I wish I could run a welding bead as smooth as these. One didn't even have any touchup grinding. I'm not due for a valve adjustment yet so it will be awhile until I can report back. I expect them to work as designed.

However, I did encounter one major problem that I should alert others about. My wife saw these in the utility room prior to me putting them in the tool box. She was certain I had cut up her knives and was quite hot about expressing her objections. I had to print off part of this thread before she agreed I was innocent.

Hmmmmm...... Uh oh.. That just gave me an idea!

I have a nice set of really thick knives with the hammered finish. I may have to mail those off to him.

They would look sick!

Well, that is certainly in my offering. If you have something in your kitchen or garage that you would like as handles on your custom MB wrenches feel free to send them to me. As long as they are weldable I should be able to handle it. Hey I made a joke. Handle it. Thanks

Has anyone looked up monstercraftsman. He has a really nice set of wrenches. Plus a trap ox replacement pipe - for test purpose of course.

I bought a pair of wrenches from him. They worked quite well when I adjusted my valves.

I filed down the edges on one wrench so the " bite" i guess of the wrench was a little wider. I was having trouble getting the wrench onto the bottom locking nut.

This is from 2004 as the overall view....

Ok,, just for reference for others in the future who find this thead... or do a search ....
The valve adjustment on these old overhead cam diesels is done by adjusting the position of a nut which is threaded on the actual valve.... the valve has a slot in it and a wider nut at the bottom of the adjustment stuff but above the valve seals...has a tang which fits into this slot..... it can rotate with the valve rotators fitted in most of these engines.. but allows a way to ' clamp ' the valve rotation for adjusting purposes...
In the event that the top nut or the next lower nut ( which is used to lock the top nut at the proper height ) are stuck... the wider, slotted nut is used to hold the valve from rotating so the upper two can be set and locked together...
That is why you sometimes see people post saying that they have never had any problems and don't need any way to hold the lowest nut. But , IF just ONE valve adjuster nut is STUCK.. then you need that lower one to get it loose enough to move.
Most people find that the bought lower wrench, due to it haveing a ' stand' which holds it at about the right position.. plus some combination of to bent wrenches ( I got Crasftsman and bent them myself ( being cheap ) are very helpful for doing the valve adjustment.... But I bought the lower one after trying and failing to make it ...
I am sure we will have several posts now saying basically " you wimps" ' I have always used plain wrenches and have never needed to hold the bottom nut'..... LOL

I recommend saving a coin jar for a set of Hazets. I got a set for Christmas (you should of seen the look on my face) and they make actually make valve adjustments fun. The retainer wrench is incredible

The retainer wrench is basically the ' third hand' some people have expressed a desire for when doing this job... since it has that little stand to keep it in place while you use the two top wrenches for adjusting and locking the nuts while using the feeler gauge at the same time...

You wimp. I do my valve adjustments with my fingers with the valve cover still on!

Now a real mad man would try to adjust his valves with his teeth

I bent my wrenches with my teeth...so I do not have anything else to prove by adjusting the valves with them... the veneers were expensive but now they look nice again...

The first time I adjusted mine I held the valve and rotated the car. Biggest problem was tire smoke as I rotated it sideways. Thanks
