How do you use these?

How do you use crowsfoot spanners?

 

[Chequeac]

And what situations would you choose them over a normal spanner

 

[hangfirew8]

Usually, at the end of a long extension from your ratchet. The situation would probably involve lack of clearance for a conventional socket or wrench.

or hydraulic lines

there is a picture somewhere where an astronaut has one on a ratchet at an odd angle. Nevermind found ti:

Weight reduction

Looking at that instruction sheet, I still have no idea how they would be used. Seems like you would have little to no leverage.

And, where can I get an Infinite Length Breaker Bar as shown in that instruction sheet?

 

[CutterFarms]

Surprisingly you do have leverage with them, and they are very valuable in tight situations. I have even cut down a wrench and welded the 12 point side to a extension to get starter off of a John Deere tractor.

 

[ebonyswan]

the only way I could get the EBPS (exhaust back pressure sensor) out of my ford 6.0 diesel was with one....

If it is not clear, they mount onto a socket wrench - or a socket wrench extension - which was what I had to do.

You actually have a shocking amount of leverage with them, but you do have to reposition them regularly as they rotate if you are working in tight quarters (and why the heck are you using one if you are not in tight quarters...).

 

[dutchgray]

They are for when there isn't room to get on a fastener with a normal wrench or socket, then you absolutely need them as they may be the only option that will work.
Most of mine were bought used and many are Snap-on, they are one of those tools that are generally little used and go very cheap second hand.
A must if you work on hydraulics a lot, but I have used them on domestic plumbing as well.

 

[monkeyspanners]

I have used them on these, though in this case i made do with a ring spanner to hold the bolt head. I have a 7/16 crow foot and long extension for doing these but don't keep them on the truck now, used to change one or two a week but can go six months now without seeing one.

This is on a 500 gallon bulk milk cooler based on a design by Dec international from Wisconsin.

3/8" 90 degree connector FZ1

1/4" 90 Degree connector TZ1

Be warned, these connectors are designed for low-medium torque.

Yup, and I have noticed the majority of crowsfoot are usually 12* point Flares or 6 point flares. The open ended are also plentiful, but less needed for tubing.

I needed to replace the throttle cables on my '07 Kawasaki KLR 650. The way they were attached to the carburetor precluded the use of a wrench, next try was cutting cable off so I could slip a deep well socket over the hex on the cable end. That was no go either, the walls on socket would have had to be paper thin to work. I picked up a nos 1994 Snap-On 12mm 1/4 drive crowsfoot somewhere for like $2 used that on a 1/4 spinner handle to do the job.

Power steering hose fittings on my old Corvette. If any other tool works for
this, i'm not aware of it.

 

[atomicpunk]

I used them replacing fuel lines on 2 stroke Detroit Diesels.

 

[Whiskeymike]

Very common for jam nuts on adjustable control arms and track bars. Attach them to a torque wrench where a socket can't go.

 

[Bagherra]

Used them all the time when making pitch change adjustements on helicopters.

I've used mine twice or three times in the past couple years; in each instance it was on a power steering rack. Ssmtimes it the only thing that will work
