The $20 LB7 Injector Cup Tool

[bullfrogjohnson]

I have talked about it before but I finally took some pics.

This is what you need:
3/4" concrete anchor with a 7/8" head thats 7" long
3/4" nut
Big 3/4" fender washer
A piece of pipe that has a minimum of 1 1/8" ID and a max of 1 3/8" OD around 3" long.

And here she is

I love diy tools lol have a whole toolbox full of them for random machinery this and that's that take "specialty" tools, I can't see spending the 100 bucks for a tool I use maybe twice, I definetly will be adding this to my custom box

You would spend twice that amount if you really needed it. Question do you have to use a new rock bolt each time or do you just tap the tabs back down? What kind of wear and tear do the do to the cup? IE can you reuse them?

I just used bullfrog johnson's anchor bolt special, and it worked perfectly! The inj cups came out just fine with no galling or distorsion to the cup. :thumb:

Great to hear!

Great to hear!

happy as shit, that it worked. I was worried that I would have a hell of a time getting the cups out.

Where would a guy find a 3/4" Concrete anchor wedge that has a 7/8's head and 7" long? Will be in the Billings Mt area today looking.... they only have a 8.5 inch long one @ Home depot. I suppose I could cut it to length a?

just cut the pipe longer to take up the space.

Injector Tool

Does anyone have one of these they would like to sell me? Suppliers around here do not have anything close to this. I have a stuborn cup and need some advice if possible. Does the tube on this kit allow the cup to come up in it once tight? I have the kent moore j45910 tool but it does not have the cup portion. Give me a shout if anyone can hook me up, Randy. 307-431-2482.

Not sure..is this a standard 3/4" diameter concrete sleeve anchor bolt?.. most of the ones i see are only about 6.25" long. - The original post says 3/4" nut... but a 3/4" anchor has a 5/8" nut..

Better yet...what is the inside diameter of the cup being pulled?

Trying to get all my tools together.. P0093 getting worse.. and worse... no leaks.. no fuel in oil...will check internal bypass.../ fuel return

Thanks!

That's pretty slick! I'll have to make one of these one day.

1 picture shows two nuts (one on the anchor itself and one with the fender washer).

I'm assuming only one nut is needed?
Also how tight do you have to get it and what keeps the inside from turning in the cup (initial setup to have it contact the inside of the cup)?

Thanks.

I just realized the first nut must "set" the fingers, and the second nut presses against the "sleeve" to lift the cup out......????
