Removing Shimano FFS cassette
#1
I'm (still) working on a 1984 Schwinn World Tourist, which has Shimano's Front Freewheel System.
Everything seems to work well on the bike already, so all I'm doing is replacing the brake cables & pads, cleaning, removing surface rust and overhauling the bearings.

The bottom bracket doesn't look like it'll be a problem, but I'm currently stuck on the rear cassette. I haven't been able to find any useful information. So far I've checked Sheldon Brown's site, Park Tools and Shimano. Other than some old catalog pages and Sheldon's personal opinion of the system, I've got nothing.

Has anyone here worked on one of these before?

Those last pictures really show how gunked up it is. I'll try to clean that out during my lunch break and see if anything useful shows up. Splines would be nice.

OK, I found the splines; I wasn't thinking too clearly and hadn't removed the nuts and washers when I took the pictures.

This shot's blurry, but there they are.

How many splines?

EDIT: Just wandering in case I ever come across this type.

12, very shallow. I may write to Park to see if they have a recommendation, but I'm going to drop by the LBS after work today. Hopefully they can get it off without destroying it. I'm trying to get this bike done and delivered to a friend's daughter this week.

Go ahead and write park and go to the LBS today but you may find that you will need a Bicycle Research CT-4. They sell them on ebay. Known as the Shimano boss. Let me know what it is. Here is a pic of the CT-4

It looks like it would do the trick.

Wouldn't settle for that though, I don't know if you saw the thread on how to measure spline to spline but that is how you know. If it is around 19.5mm-21mm then that is the tool you need. No I got mine from ebay, which was actually 15.00 cheaper. I actually got like 3 more after I got the first one. They are ok but as I said needed better design.
