CV TECH PB 80 primary clutch (Apex & Vector)

[Redbeard]

The riding season is over for me. Post season inspection reveals the PB80'S in both sleds are good to go for next year.

Sometimes the governor cup is difficult to nudge loose by hand, mainly because it's such a snug fit on the shaft. As a result, I fashioned some rolling-wedge pry bars to gently loosen the cup. I doesn't take much; just a wiggle and off it comes. I used some key stock and old bearing races that were laying in my pile. I cut the races to shape, then tig welded them to the key stock. A dash of powder coat and that's it!

Good night until December!

This is all great news and a rally helpful write up. Did some pto noise stay but ALL the clutch rattle went away by the end of your experimenting?

I'm going to experiment with different weights in the pucks for my Apex this winter. Unfortunately, there was no room left for additional weight; maxed out.

I contacted CV Tech and they sent me the pictured heavy slugs. They are machined to fit inside the hole on the face of the puck and extend beyond the normal slug bearing area, giving me the extra weight capacity.

I updated the current calibration figures, for both sleds, in post 17 above.

Hi,
What a GREAT review!!!
I know this is an older post, but do you have the CV-Tech part numbers for the deep dish weights for your Apex? I have two sleds running the CV-Tech clutches: one in a 1992 Polaris RXL 650 EFI and another in a 1993 Arctic Cat Prowler 440 LC. Both work very well with minimal tuning. Now, I'm looking at this clutch for my 2006 Apex ER.
Thanks and Merry Christmas.

I found these part numbers on the umatek.com site.
