How the heck do you remove that last Vacuum Pump Bolt!

It’s all going smooth until you miss the nut with the screwdriver and ding the threads on the end of the stud and then with the nut jams up on the end of the stud, keep hitting it with a screwdriver until it bends  the stud and then it really won’t come off and  end up hammering the shit out of it was a 3 pound hammer for an hour until the stud snaps off. Yes.

That’s the way many of us were taught.  The youngsters in maintenance schools are told to get a special tool, not a hammer and chisel.

Get the tool, damn the torpedoes. 

the Rapco Vacuum Pump Wrench is absolutely a must.  My A&P let me struggle to get mine off (I used a drift to loosen the last nut, then spun it off with my fingers) but he gave me the tool to put it back on.

I resemble that remark but although far from a youngster, I was taught to use the right tool for the job and never take destructive tools like a chisel and a hammer, or even vice grips, to an airplane. 

Here is how I torque the vacuum pump back on using a snap-on vacuum pump crow foot. They make one for TCM fuel pump nuts which is also helpful.

 

 

 

But of course you old timers could teach me plenty!

I have that crows foot wrench which does work well.  It lives in a drawer with a number of other modified and welded wrenches for various jobs.

VP crow foot? Kinda like iPhone to rotary dial! :-) :-)

I got the special "Rapco tool" and it did the trick.  Still hard but no hammering required.  It will be a trick to get the new vacuum pump back on.  Now I have a new problem and I'll start a new thread for that...

But thanks guys for your recommendations.
