Great gadget. I didnt know about it until I saw it in the catalog. Saved me a lot of time and labor.
Great service as ususal.
Must have tool if you ever need to replace the dry air pump.
Awesome tool, buy it and save yourself lots of time and aggravation..
I spent 25 years maintaining light aircraft. While I did have to get adept at grappling with that bottom inboard mounting nut, only now that Im retired did I purchase this wrench - 25 years too late! It is a really helpful tool that should be in every tool cabinet.
works great and makes the job very simple
If you are changing a pump GET ONE OF THESE, MANDATORY!!! It is a PITA getting the lower left nut on by hand and nearly impossible to tighten it with out this wrench.....
First time changing the vacuum pump and this wrench made it so much faster. Well worth it.
If you dont have one of these, you will spend hours and aggravation trying to change a vacuum pump. Perfect tool.
Works great in tight areas.
