<<the DWB tool (four pins with a large flat tab sticking out) is needed for any of this.>>
I have that tool and it's a well make and designed tool.
Thanks for all the info. I am aware that Todd is short on parts.
It sounds like I should stick with ACS freewheels. We don't have hills other than riding up the levee. So, changing from the 17t freewheels isn't an issue for us. I haven't pulled the freewheels yet. I wonder if the model number will be visible if I pull the freewheels. Will I need any special tool other than the DWB tool to pull the freewheels? I have already pulled the intermediate shaft once, so I have a chain whip and a locking wrench.
