for the taking apart part, watch out for the spring tension after you remove the 3 12mm head bolts. as for assembly, there are certain holes the spring needs to go in on both the sheave and the helix. place each end of the spring in the proper hole and push down while twisting clockwise to align the studs to the holes. an extra set of hands for the nut to stud installation will be handy for someone who hasnt played with one much.
Just to add to that. The holes are numbered, if you add the numbers up that is the degrees x 10 of tension. (1+6x10=70) The higher the number the higher the tension. To tighten the tension change the spring holes. (2+6x10+80)

how much pre-load should there be on a p-85 its 1/4 turn counter clockwise i did that out of habit and it does'nt seem like enough

a p-85 would be your primary,made by polaris, and there would be no preloading it has there are alignment marks on the cover. you lost me there somewhere. your secondary should be at 80*(6-2), with a red spring.

sorry about not making sense the sping is black/red it is in the 6-2 position what i'm wondering is while pushing the helix in how much do i twist while puting together on the polaris secondary its 1/4 turn

on the yamaha secondaries, the amount of "twist" is proportionate to the chosen degree. in other words, and for simplicity, if you setting it at 6-2, you will end up twisting nearly 80*, or line the pointy part of the helix up ahead of the pointy part of the sheave and twist until the bolt holes line up, which should be around your desired degree angle. the more angle chosen, the harder you have to twist both the helix(clockwise) and the sheave counter clockwise. sometimes three hands help with starting the nuts, which should be torqued to 17 ft lbs.
FYI Polaris runs their secondaries alot tighter then Yamaha does.
