Hope I'm in the right forum.
I have a Shimano two-notch 600 freewheel (13 - 26) on a Shimano "Sealed Mechanism" large-flange hub laced to a 26- inch Ukai rim. Early 80's stuff I think. The freewheel is in pretty good shape and works, but it will wear out eventually. Do any of you freewheel experts out there know whether I can replace this freewheel with a spline type (such as an IRD) when the time comes? I don't think it's going to be easy to find a Shimano 600 two-notch freewheel.
Thanks in advance for any input.

I don't think it should be a problem. Sounds like a standard British threaded hub, in which you can install any freewheel that you want. A splined freewheel is a lot easier to remove than any 2 notch one. The 600 ones were a bit touchy to remove.

I never found any significant difference between the two. You do hold the tool on the wheel using the QR skewer, right?
I replaced this very freewheel with one of the hard to find Shimano 11-28 ones. No problems.
A Regina two-prong freewheel tool will also work on the older freewheel.

A Shimano 600 freewheel likely has the proprietary Shimano Dura Ace/600 design. A 'normal' 2 pronged freewheel tool will not fit without modification. You need this tool, as shown on Velobase:

Thanks so much for the input. Thanks to input like this (and to the Park Tool Blue Book, and other sources) I'm learning about the tools I need and what can and can't be done. And I'm getting the info I need in order to talk intelligently with LBS pros. Much appreciated.
