We got millions of them buggers around here and every once in a while I find the yellow jackets building a nest in or on one of the machines. I use the 20 ft range garden variety bug and wasp killer. The smell from it drives them out even if it does not kill them all from contact. A few years ago they nested in a canopy tube on a tracked T500 Int. log skidder. They went in thru a 3/8" bolt hole. I sprayed it up good at the hole and the next day there was hundreds of them on the ground by the hole. They got enough on them crawling out that they expired on the ground below. Another time they built a huge nest in my stickered pile of sawed black ash boards that was air drying in the shed. I sprayed them and in a couple of days they abandoned the nest completely. Good luck and let us know how you make out.
Old Iron Habit's 20 ft wasp spray is a good choice. Another option is to mix a soapy water solution and spray with garden sprayer. G
This reminds me of a situatuion many, many years ago, that I had. I was moving our D7 to another place to do some dozing. I drove past our orange grove and right near it were some bushes, grease wood, that had several wasp nests on them.
Well, since I could NOT let the situation go, I moved over to the bushes and lowered the blade to just above ground level. I put the D7 in 1st gear and started moving, full throttle. I lay down in the seat so I was not a target.
BOY did those wasps get MAD. Some were sucked through the radiator, others were trying the sting the exhause pipe. I cleared the area and then went on my way. I determind that they must be heat seakers since the only attacked the exhaust pipe. WOW, what a surprise they had. They'd land on it to sting but OUCH, their "feet" got hot. The didn't stay on the pipe long.
Boy did I enjoy pissing them off. They never even came close to me.

Walt don't let your bravado carry you away.I have done the similar as you and watched many a Yellow Jacket go to its death down the exhaust pipe. Working ground in the fall and spotted a nest were the next pass would be so I kicked into 4th gear with a down hill run at them,many got sucked up in the air cleaner and down the exhaust but several made it down my shirt as well.They were much more persistent than I had seen them before.So at your own risk.
Have read they are only able to chase bears and such off by going after there noise and eyes so they are looking for the warm breath to help find the target.
You would think bees would be put off by grease and oil,but has seen a number of old tractor carcasses with bees living in them.So Boots it just depends on if you have a warm fussy place for bees or don't care.Smoke should drive them out,or just wait until after dark when they are all home and spray can of bug fogger in there entree hole should take care of them.

Diesel fuel will kill them almost instantly if it gets on them. Dash some up in the track frame or better if you have an old fly sprayer to spay it up in there.
There's nothing inside the track frame that fire will hurt, but it may be hard to get it to draft through that long horizontal cavity. Much easier to spray in there with any of the aerosol bug killers. No need for the 20' spray in that situation, a fogger will do the job just as well but either one will work.
I would unstopper one end and quickly spray a healthy dose in there and then plug them back up. The vapors should penetrate and kill the whole bunch.
