Need to know if its possible to swap my 05 snopro 440 with a zr600 tripple or zr800

I am just reassembling a p85 clutch from a 1996 srorm 800. I was just wondering if I need to use loctite on the spider and the jam nut. The manual that I saw online did not mention loctite , but it seems that some people use it for reinstalling the spider. It was a beast to take it apart.

I have a panther 570 that has I'm putting the chain case cover back on but I'm not sure about where everything goes such as reverse lever linkage and the reverse switch, is there a video showing how to reassemble? And would high pressure gear oil work as chain case oil?

I have a 440 fan engine out of an Arctic Cat serial number K44-101975 I need to know what year and model the engine is, any help will be appreciated. Thank you.

Can anyone help me figure out what model and year the following engine serial number is for? K44-101975. Thank you.
