hello, is there any way to remove Freewheel REGINA (20 spline) without tool?

JohnDThompson 

Non-destructively? No.

The splined tool should be readily available, e.g.:

There ‘might’ be. A 20mm hex head bolt, 20mm Allen wrench, or a maybe a socket that has a 20mm hex fitting on the outside of it fit snugly enough into a Shimano freewheel for removal. If the 20mm bolt/allen/socket doesn’t fit in the Regina freewheel…try other sizes.

Why do you want to proceed without the proper tool?

If it has a ring with 2 indented holes, you can spin this off by spinning it around using a screw driver and light taps of a hammer. You can then remove the gear set but be warned that dozens of tiny ball bearings will then fall all about. Once the gears are off you can use a pipe wrench to remove the remaining part.
THere are instructions on you tube on doing this and if you're careful you can re assemble without damage.

Don't know where you are, but if you want to preserve the freewheel and be able to remove it later, get the appropriate spline tool. In the US, you can order it and it appears the next day at your door, but I realize that if you live in some areas it may take longer.

thanks, i saw the video but unfortunately the one I have does not have the 2 indented holes :-|

Local bike shop near you? They'll probably loosen it for you if you take them the wheel. Maybe even for free. You don't need a tool to put it back on the wheel.

I managed to remove the sprocket but I can't unscrew the final part, it's too hard.
I'll post the photo in the next post

i have worked on machines from every Continent except Antarctica.. i have NEVER seen a 20 mm hex head bolt or fitting... ever.
Standard open/box end Wrench sets include a 19 and 21 mm Size.. Why is there no 20mm size wrench? Because They Aren't NEEDED.
the oddest Fitting size i've run into is a few Kubota models, and a couple other brands of tractors, that used a 26mm Fitting on ONE of the Front loader hoses at the junction block... i then had to grind away part of my shiny new Snap-On Wrench to gain clearance and allow a 1/6th swing per pull....

You CAN buy a 20mm allen wrench, (Special Order,McMaster Carr) but it costs about as much as THE PROPER TOOL used to Remove Regina Freewheels, and you'll pay whatever shipping they decide to bill you ..... all to realize that BUYING THE CORRECT TOOL would be faster, easier, and safer.

or someone could try using a 13/16" allen socket on it, then decide to BUY THE PROPER TOOL anyway... .

Regina Freewheels are notorious for getting stuck on hubs... I've resorted to Cutting the center portion of the freewheel in half to salvage a valuable hub before.. it is a lengthy and nerve wracking job since cutting into the threads of the Hub is NOT an option... you cut carefully with a disc cutoff tool, inspecting every few seconds for ANY HINT of thread grooves showing, then use a chisel to split away the freewheel piece..... or hope the HEAT from the grinding loosens the Regina death grip on the hub....

do yourself a favor.. get the correct tool... and apply heat if it doesn't work on the first try.

I have an Easy Out, Hnason EX-8, that I've used for a few freewheels. It's tapered section is aprox from 20mm to 25mm in diameter. But I've used a bench vice, a pipe wrench and a 1/4" die grinder to remove the inner body more often. Andy

OK…I guess it is 21mm. Point is, either a hex wrench, the hex on the ratchet end of certain deep sockets, or the head of a 21mm bolt fits perfectly into Shimano freewheels. Placed in a vise, they can be used to remove the freewheel without damage.

In just about every activity that I've ever been involved with I have always been amazed at the lengths some people will go to rather than simply doing something the proper way. That would be AMAZED !

SkinGriz

Now that I think about it, I never see a 20mm either. I see 19mm often for which I can’t tell the difference from a 3/4. Same with 24mm / 15/16.

_ForceD_

Concur. But I don’t know what the OP’s financial/time situation is. If you don’t have access to a fully stocked shop, are on a budget, have time constraints, or otherwise just can’t get your hands on the tool made specifically for the job in a timely manner, etc., and you have the necessary materials readily available…why not use a, safe, suitable alternative to get the job done?

I've seen way too many results of alternative methods to be much sympathetic to your suggestion. And none of the above suggestions seem to me to be any more convenient than just getting the proper tool. Freewheel tools abound. Not many bike shops don't have them and they're available from a multitude of sources for a couple dollars.

But, of course, people are certainly free to use any legal means to solve their problems.

Best of luck

Yes, that can work, but it requires removing the hub axle, and seating it properly may destroy the hub dustcap behind the freewheel. And I'm not sure what might happen to the remover splines on the freewheel body; I've only used this with notched-type freewheels. Schwinn sold a version of this tool that was truncated so that it would extend only as far as the dustcap, thus preventing damage to the dustcap.

I have about 15 different freewheels and for some of them I have been trying to identify the correct removal tools for for several years. Just Identify them, much less source and buy them.
some of them - like the 600 CE - have no obvious (to me) slots or splines into which I would even stick a tool if I knew which one i needed.

Park FR-4 is good for Regina CX-S?

sorry for bad photo

pstock

thank you.
But there is a question mark at the end of your sentence.
did you mean to ASK me ID a FR-4 would work on a Regina CX-S? (I have no idea)
or are you telling me it will work (which would be a great help)

It's possible to successfully reassemble a freewheel, after disassembling it and using a pipe wrench to remove the body from the hub. Just don't lose the bits, and be careful where you place the pipe wrench. Of course it's generally not worth the effort, unless it's a particularly good freewheel.

I did as grumpus mentioned and was surprised and pleased that the freewheel worked great, and still does. I had to file down one spot where the pipe wrench bit into the remaining bit on the hub a little too much.

glysolid

yes that was a question. however I think FR-4 is ok because it has 20 splines.but what is the difference between Regina and Regina Extra?

pstock

yes, this is where I am completely lost. on the oddball freewheels
