Speedometer driver disassembly

[Coyote]

Attempting to disassemble and clean Schwinn speedo drive unit to degrease gunk.
Now I am having a difficult time removing the black plastic cap to get the worm shaft out.
Is it a threaded cap?
If so, is it a clockwise or counterclockwise turn to remove?
Would love to hear experienced technicians' advice - thanks!

That cap is threaded. Try using some pliers on it, they get a little sticky with age.

Make sure you are in a warm environment when you do it. Plastic, especially old plastic, cracks easily if you work in an unheated area like my garage.

I've had bad luck with them things. Be gentle.

I'm wondering if a small strap wrench might not be the best choice here. The rubber band grasps the entire circumference of the part.

Strap wrench - The rubber band grasps the entire circumference of the part.

Yep, that was what was needed.
I "thought" the cap was threaded, but it was tighter than finger-tight and a metal tool would scuff the surface.
Using that, it came right off, it was just gunked up.

Thanks to all that responded!
