I’m Clint Bowers with Brace Tools, and today I’m going to assemble a two and seven eights brace tool motor head just to give you an idea of how they go together. So I like to start with the circulation sub. I've pre-installed all my O rings and shear screws and everything just to speed up the process.
For our circ-sub, I've build myself a spacer that’s 2.6508 inches long. Just set it inside the tool and that’ll help me align my circulation piston. So grease my O rings, install the piston the small end down, press it into place. I have a piece of brass that helps me tap that down.
Once that’s down to where the stopper is, we can screw our shear screws in. For this application, I’ll just screw in a couple of them all the way just to hold the piston in place. You can put in as many shear screws as you want for your shear value.
We’ll set that to the side for now. Then we’ll take our piston for our collet for the disconnect. And we’ll install the top piston,were the ball seats into, thread that on, slide our piston through our collet, install the shear piston, then clamp that in a vice, use a crescent wrench to tighten all our parts together, take an allen wrench and screw in all of our shear screws.
You just want to screw them in until they touch the bottom of the groove. Don’t torque them or push the fingers of the collet out. Once those are all screwed in, we can install that into our release sub. The release sub has an octagon shape in it so that when you install your collet in there, you line it all up, turn it and it locks into place and it can’t rotate.
Take that release sub in the vice, take our circ sub, install it into there, hold your collet piston and everything from being able to travel down for the rest of the assembly, install our fishneck.
At this point, you torque your fishneck to spec onto your release sub. Then we’ll take our next sub and slide it to the top of there. There’s two O rings on here so it takes a bit of force to get those over. We want to give it a good shock to make sure that’s seated in there so that our threads will start on our release piston. You’ll feel a vibe if they don’t.
And if it goes all together good then they’ll just thread together. Once that’s snug, we’re set there, we take our top sub and our dual flapper sub and install our top sub onto there, turn that upside down. Your flapper cartages, you make sure you put them in the right direction so that when you're flowing through it, your flappers are going to open.
That should sit pretty flush there. Set that up, put that end, torque that end to end to spec and you're ready to run in the hole. If you choose to go with lower shear values, you will remove the shear screws from your circulation sub or your disconnect piston as desired. Thank you.
