REPLACES ORIGINAL NUMBER 8-8000SV ON SV8000 REEL
Confirmed by www.mysticparts.com, does fit in SV reel as per Penn, even though the original SV gear had teeth on the tip of each end of the shaft and the CV gear does not.
Grinding Gears:
The quantity of shims required to tighten up the play between the
main gear and pinion gear varies by each individual reel.
Some reels will not require the use of any shims, while other reels may
require the use of up to three shims to achieve the desired result.
The shims used on the 8-8000CV main gear are part number 8A-8000CV.
See "Related Products" below to order the correct shims.
DISCONTINUED AND NO LONGER AVAILABLE
There is no other compatible Penn gear that fits the 8000CV reel
The SV reel could use the 8-8000CV, but that compatibility did not go the other way and the SV main gear wasn't compatible in the 8000CV reel
Later CV2 gearing also not compatible
