Driven Clutch dis-assembly help

[easygoin4]

I have our first father/son FL250, never heard it run but going thru all parts first. Engine is free and should not be an issue.
I am on the clutchs now- I have the motor out with drive clutch still on- my problem is the rear driven clucth.
I have it on the bench off of the reduction gear- lossend the spring by turning off the boss inside helix, snap ring is off.
Cant get the helix off- I have been soaking with PB Blasters for 2 days- Should it not just slide off the shaft connecting the pully halfs?

I have tried a little heat from a gun to see if I can expand the metal and get the blasters to go down but not sure if any plastic inside to damage with alot of heat.

I have a puller on it now with a little pressure on it too- but DO not want to break the soft metal.

Any help would be great- Thanks in  advance.

After I get this done I plan to disassemble the Drive clutch to inspect and clean up.

Are you referring to the ramps when you talk about the helix? I assume you got the outside ramps off,but the section against the movable face is stuck?

ok I got the rear (driven) clutch apart ,cleaned and back together.  Now I am on to the Drive clutch on engine- got all apart and cleanedd but now have to order a puller to get off crank- cannot get spider back on using clutch bolt into crank I think the spider is not only splined but tapered. what a pain.

[girth first]

it is tapered but not splined. i use a 7/8 nf bolt about 5 inches long i believe to get the stock one off of the crank if ya cant find a bolt  you can use a piece of althread and weld a nut to the one end, then use an impact wrench to rattle it off. good luck

thanks for the input- I have ordered a puller and will have in couple days- my bigger problem is getting the spider back on the clutch shaft- it has splines and when I get entire clutch off crank I will use a threaded rod of some sorts and make a spider installation cup of some sorts to press back on clutch.
any trick on this?

You don't say what drive clutch you have, but the Skidoo I've pulled apart was just splined, but a tight fit that was tough to get just right to slide back together. Rigging up a holder while using your threaded rod should make it a bit easier.

I would assume it is original clutch not sure brand- but there is a spline around the shaft about 1/2" long cleaned the groves out and greased up- she is a bear to press back on- made a tool to stradle the shaft and press down on the spider, yet to try it.
Thanks

May the force be with you!

And the Force was- Got the spider back on now both clutches are free and hopefully work fine.
Used long threaded rod in vice- homemade cup to install spider- worked great.

On to finish assembly- thanks for all the help...
