I am trying to remove the driven (secondary) clutch off of a 1970's ski doo jackshaft, but I am pretty inexperienced with these clutches. I have soaked the clutch in PB blaster for the past day and a half, but have no luck trying to get it to budge. Is this a thread off clutch like the primary? it looks like it is keyed onto the shaft, so I wouldn't think it would be.

What's the trick to removing the clutch from the jackshaft without breaking anything?

Try leaving the machine on it's side and let the PB soak in. What model is it?

Not sure the exact sled but I want to say an early 70s 377 (380?) I got it from a donor sled for a 440 F/C. I have the clutch and jackshaft out, just sitting upright in the vice now soaking in PB Blaster
