A hook spanner wrench is usually used on fittings with wings; which would be the opposite of the slots you describe. The threaded hose fittings on fire hoses are an example what you'd use a hook spanner on.

The other type of spanner is a pin spanner; they're used on fittings with two holes in them; like on the threaded collar that holds a grinding disc on an electric grinder.

Used for quite a bit more than that in industrial settings.............

I was wondering if anyone knew a good tool to remove the collar nuts on cartridge struts. I saw a socket with pins that fits right over the strut for BMWs, but it was $90. I remember looking at an OTC pin spanner set for about $50, but IIRC it was for holding cam gears so might not have the necessary strength.

At first I was thinking a pin spanner, but it doesn't have holes, it has two slots/notches across from eachother on the face of the ring. Maybe find a piece of bar stock about the same thickness? Money is tight, so I was hoping to avoid buying an expensive tool I'll only use a couple of times.

I used these type spanner wrenches on fire hose collars and nozzles. The fire hose threaded collars had wings on them, not slots.

I use them all the time for lockrings on this type of bearing. Wrench is struck with a mallet to a predetremined spec using a feeler gauge.

I noticed Armstrong has a hook pin spanner wrench too; I've never used those though.

Do they make a tool that looks like a pin spanner, except with flat "posts" instead of round ones? I think I need something like that.

I have a set for eccentric locking collars used on some bearings to lock the bearing to the shaft.

An adjustable hook spanner is the tool I have used for those type of nuts.

Ok guys, I don't have a picture (sorry) since it is put away right now, but I'd like to remove the retaining ring/nut on my Lincoln floor jack. It is a ring with 2slots cut out of it. I did some research on the net and I'm guessing that I need a hook spanner wrench for this, correct?

Are there any tips/hints so that I don't have to buy one. I don't want to use a chisel or anything that will mess it up. Thanks

You are correct. To use the proper tool you would need a spanner. I have rebuilt numerous jacks that had retaining nuts just as you described. I have used old blunt ended screwdrivers and blunted punches and the like to remove and replace the nut. I never used a cold chisel or anything like that. I think you will find that if you are careful in the tool you select an improvised tool should be no trouble at all. A bit of patience and creativity and you should have the nut off in no time. :thumbup:

I found a bunch more spanner wrenches here:

There's a good chance that the adjustable hook spanners they were giving us to use were not the optimum tool for the the job. :D

I second this, when I worked at a Kubota Dealership the fuel filters used a ring that had slots in it. Instead of buying the hook type spanner wrench I used and old flat blade screwdriver. Worked great at 1/100th of the cost of a new set of hook spanners. The jack may require more force but a blunt chisel should work just fine. IMHO

i would just use a screwdriver or punch.

Something like this

A pin spanner would be your best bet but a drift punch properly utilized would work as well

Elroy's picture reminds me very much of the threaded locking collar that's used to secure a Briggs & Stratton muffler to the cylinder. :)

Guess I should have read down the posts before posting my replies. If the nut is like Elroy's picture, you need a spanner socket similar to this...

Maybe find a suitable size piece of pipe. Take a grinder to it to leave two "pins" on the edge. Turn it with a pipe wrench.

Edit...
Another option is to sacrifice a socket. Hit the socket with a grinder to leave pins on the edge.

Yes, I think this might be the best tool for the job. In a perfect world I would order this, but it costs more than I paid for the jack.

Thanks for all the suggestions guys, I appreciate it. I think I'm going to improvise, as suggested.

I have often used one of those weak ass, tiny air hammers, and a brass tapered air punch. You only need to break the nut loose, then it will spin right off.

A brass pin punch close to the size of the slots would make a very good improvised tool. ;)

If it just a one time thing visit you local bicycle mechanic we deal with hook spanners and have pliers to do the job.

Not entirely true. What happens when you need to torque the nut back on?

I would like one of these tools, too, for using on Bilstein shocks. Seems as thought the newer Bilsteins shocks don't come with the tool they used to. Even when they did, the simple tool was kinda lousy and often slipped off. Not sometihng you want when your trying to avoid marring the strut tube.

For a strut, you can't use a socket, so you gotta use a wrench.

For farm equipment with fittings like that, we just torched out the rough shape, then got some key stock and welded it to it. Presto, custom wrench.

A adjustable hook spanner or fixed hook spanner wrench is what you need, measure the nut to determine the size wrench you need. You can pick them up on eBay for very little money. A spanner socket will work also but not a common as the wrenches and will probably cost you more. A lot of the machines I work on use spanner nuts. I have sets of the different type of spanner wrenches and sockets, a must when you don't want to damage the fastener or when making fine adjustments.
