some of these clutch covers look like they met the drill press in a high school shop class.

I notice no serial number in the cover. That’s odd cuz the last year or so there have been serial nums in the cover and stickers that say the part num and date.
If the customers are confused, it’s actually the company that is confused.

Yes that is the ACTUAL CAT part number but WHAT IN THE ACTUL FAKKK is going on here!? You are the first clutch to post in this thread with the ACTUAL CAT part number stamped on your clutch! All others posted including mine from my 2020 has a made up part number from the 90’s that doesn’t actually exist all clutch part numbers posted have been a 0725 part number series
KaneDog is asking for your SN# it should have a SN# stamped on the clutch and a green quality control sticker. Also I’m curious to know how many balancing holes your clutch has drilled into it?
Cross reference guide that I posted before:
2020 part number is CAT part #0746-895
2018 and 2019 is CAT part #0746-885
The part numbers we have on our clutch covers are a very old arctic cat part number 0725 series was from the 90’s the part numbers we have on our clutch covers make absolutely no sense at all? WHY do we not have the Cat part numbers stamped on our clutches? When you enter in the 0725 part number that most clutches have stamped on then nothing comes up?
CLUTCH,DR.UNCAL-TEAM-HDI33MM (423460) is the team cross reference part number for the newest 2020 clutch CAT part number 0746-895
CLUTCH,DRIVE-UNCAL-HDI33MM (423215)
Is the team cross reference part number for the 18-19 CAT part number of 0746-885 (which replaces/supersedes part number 0746-876)
CLUTCH,DRIVE-UNCAL-TEAM-HDI33MM (423031) is the team cross reference part number for 0746-876 (this part number is more then likely the original part number that got recalled)
2020 part number is CAT part #0746-895
2018 and 2019 is CAT part #0746-885

The KBI clutch investigation division has narrowed the cause to three possible scenarios.
1. Turbo or supercharger power applied to stock secondary spring and helix. Or incorrect spring and helix. Primary yanked open the secondary and made the belt slip. Major belt slip evidence present.
2. The secondary clutch bolt has backed out due to engine harmonics. The bolt vibrated itself loose but not enough for the bolt to fall out. Just enough to let the sheaves spread apart and not quite enough for the sheaves to fully squeeze the belt.
The clutch is now partially open and loose and the belt dropped down low into the sheaves. Under WFO, the primary yanked the belt way down in the secondary. The belt slipped like a mofo in the secondary and wore a few holes in the sheaves. Dude prolly rode it a while hoping it might fix itself. We all do that sometimes. No biggie.
3. The dude incorrectly assembled the secondary.
The Team Boss secondary clutch design is not good. When and if the bolt comes loose, the outside sheave can come right tf off and now there’s an 8000 rpm 11” disc of death bouncing around in the clutch area. This can be veddy skeddy.
Just smoked a fatty and now the bolt and washer bother me. The bolt and washer are two different types of metal treatment. It looks funny. Don’t know if it affects affects anything tho. Oh, and the washer hole is too big. Notice how the washer is off center. The component rotates at 8000rpm. It’s important to have tight tolerances on rotating components or vibration may result.
Crappy clutches stress me out. I gotta go to bed, this is much too stressful.
KBI investigation is now concluded. No guarantee of accuracy or correctology.

I am thinking the 0725-978 is the latest and greatest and was changed after the parts books were made. If that is not the case it does not make any sense or we don't have all the facts yet.
