4 prong freewheel removal tools?

[PpPete]

I got rid of my last pronged freewheel (and associated tools) years ago, thinking that for the few remaining freewheel equipped bikes I'd only ever use splined (Shimano-style) freewheels.
Which of course has come back to bite me in the proverbials.
I just recently acquired a fixed-free flip-flop hub, built up the wheel, put a Sturmey-Archer single-speed freewheel on it, mentally adding "4-prong tool" to my shopping list as I wound it up tight...
But now I come to buy there seems to be a variety of 4 prong types...
Park website list various manufacturers - but not Sturmey Archer
They have three different models pictured:
FR-3 (4 notches approx 24mm diameter)
FR-6 (4 notches approx 40mm diameter)
FR-8 (4 notches approx 32mm diameter - but has a kind of inner projection which I'm not sure would fit...
So, out with the calipers....
This freewheel measures up at 36mm diameter (on the outside of the ring with the notches, and about 4 or 5 mm less on the inside) so I'm not sure it matches with any of the above.
Googling "Sturmey-Archer freewheel tool" comes up with images of a different beast with a kind of double-depth prongs - but that might just be a device to hold the thing aligned? - and no dimensions.
There also seems to be "Cyclo" branded ones which appear similar in shape to the FR-6 - but no dimensions given....

Any advice from the assembled wisdom on which tool to buy?

I had one of those but it was eaten by a big cat. It was a four point tool eater jaguar. Geddit? four point too .. oh never mind.

No I don't have any useful advice, sorry.

Sturmey are now Sunrace, do they do one?

Sjs cycles seem to have a few, including a sturmay archer one. Try asking them.

The Shimano BMX freewheels (you don't have to use them on a BMX...) take the Cyclo BMX freewheel remover. This is probably the most common 4-prong type. Measuring mine, the ID of the dogs is 31.5mm, the OD of the dogs is 40mm and each dog is 8mm long. This is with digital vernier calipers so should be accurate.

SA make their own tool which fits any freewheel they currently make: Amazon product ASIN B014WJANR4View: https://www.amazon.co.uk/Freewheel-Remover-removal-Sturmey-Archer/dp/B014WJANR4

My sturmey freewheels seems to use the same fitting as my shimano ones if that helps. This is the tool I use https://www.icetoolz.eu/en/icetoolz-freewheel-remover-4-notch-bmx-cp/a5307?c=3600

PpPete - Did you ever find the tool you needed? I also need a four prong tool about 36mm OD. See attached pic.

That's an odd looking freewheel, do you need to take the small cogs off to expose some splines like a Maillard?

No, I need to take the outer lockring off so I can get my pin spanner into the the pin holes (6 and 12 o'clock) to disassemble, clean, and re-grease the two sets of bearings. This guy disassembles an identical setup using random bits, but I would rather use proper tools if possible.

[OT] Why can't you take the left locknut/cone off and slide the axle out, to gain sufficient access to service the hub bearings? Or are you trying to service the freewheel bearings - a 'stretch target'?

 

[rdone]

I am going to service the freewheel bearings. It will not be more difficult than servicing the hub bearings. Perhaps more tedious, but not more difficult.

Always found wrapping cotton around the pawls a bit more tricky than hub bearings

 

[rogerzilla]

Last time I did one, I used SA internal hub grease. This is just sticky enough to hold 96 balls in place but won't stick the pawls down. Fiddly, though.

I bought the tool linked above by milkfloat - but TBH I've not tried it out yet, not even opened the packet.
I fitted the freewheel, but I've been using the fixed cog on t'other side ever since.
Just measuring it now I do wonder whether it will fit....It's 40mm outside diameter

OK, thanks for letting me know.
