Title: Evo industries clutch hub
Post by: Coff 06 on December 09, 2021, 11:55:12 AM
When buying their hub would you go with the clutch pack they offer?
Or would you prefer the bandit?     Thanks.    Coff 06

The Bandit Sportsman clutch (which by the way is a proven great option) has a smaller diameter hub.  That's how they get more friction surface area by making the plates wider. You will have to decide what clutch pack you want to use first.  I believe when I bought my Bandit clutch I used the Bandit hub.  You can get the Evo basket with a choice of bearings, one of which can be bought at any bearing supply store.  The other is a Harley only bearing.  I went with the jobber option.  IIRC the machining is different in depth making the jobber bearing more robust.  My memory is not that great after this long but I do know that I spoke with Bandit and Evo Industries about the options before I made my choice.  They're both excellent with their service and freely share what they know.  I think I made my decision and gave California Phil the info and bought the parts through him.  That was also a good decision.  :teeth:

Thanks for the heads up KD. I hadn't looked into the bandit hub.I'll have to check it out and probably give Phil a call.I'm unsure of the teeth count options for my needs.       Coff 06

If you look at a Bandit disc you will see what I mean.  The surface area on the disc is larger and that is accomplished by using a smaller hub.  The basket OD is confined by the primary clearance restrictions so the only way is reduce the center and make the friction pads larger.

I wasn't aware the evo and bandit weren't compatible.So that makes the decision easier.I've always been looking to bandit when I replaced my clutch so I'll just go with their hub also.          Coff 06

I've not used the Evo Ind clutch, but hear that they're good quality. I guess what the clutch needs to hold power wise has some bearing on what's needed. What I mean by that is if you just need a good set of clutch plates or as KD said, a unit with a smaller diameter hub and wider discs. It the case of not holding that much power, it's just a money question on what you buy.

I have a Bandit and a Barnett Scorpion. Both great clutches in my opinion. My Barnett has over 50k hard miles, and still on the original clutch plates.

The evo unit only claims 120hp.I'm just over that at this point and of course never quite finished  :hyst: I had already been headed towards the bandit unit anyways so it makes the choice easy.And hey,what's another $1k  :dgust:

Guess what I'm looking at is the Barnett scorpion low profile complete assembly not the bandit.

It's worth looking into a good basket if you're getting a stout clutch.

I have an Evo Ind. 49 tooth setup, basket and all, and I have a Barnett basket to use on a OEM 46 tooth ring gear. The baskets look to be the same, as far as I know Evo does make most or all of most of them out there.

You were correct.Received the Barnett basket and it's branded Evo Industries.
Thanks,Phil. Clutch and hub are on back order so it will be a little longer before I tear into it.         Coff 06

Thanks for that.  I never had an opportunity to compare even visually to my Bandit.  The Barnett gets lots of good press and I see it has healthy width / area to the fibers.  I can see now how the Bandit smaller diameter hub used with their discs allows a bit more area.

All of the baskets are high strength Al, but no aftermarket billet basket for 99 - 06 TCs. Is there a reason that a basket could not be made out of forged steel ?

They make them for early TC as well.

I checked with them, and you have to purchase the whole drive assembly. They do not sell the basket by itself. Thanks for the response though.

One of the things that make a clutch perform better than the OEM is increased surface area of the friction discs. For example, the Bandit Sportsman clutch has a wider plate and requires a smaller diameter drive hub to accomplish that.  The rear of the basket is different because the rear surface has to be wider to accommodate the larger disc area. That's where my interest in seeing the Barnett disc came from (and I expect why FSG wanted to see an OEM clutch disc laying on top of it also). I think seeing that will form a clear picture.

Title: Re: Evo industries clutch hub
Post by: kd on January 30, 2022, 05:06:31 PM
This is an OEM fiber and steel attached together as a locking tool.  It demonstrates with a pretty clear visual the difference in the hub diameter of the Barnett steel discs.  The area of friction disc is pretty obvious too.  The Bandit has the same overall characteristics as the Barnett compared to the stock clutch.

Added later:  I'm getting a 500 error message and won't post the pic.  I will try again once I figure out my mistake.

I'm actually looking at Clutches also. Have already purchased Barnett billet basket PN# 321-30-02012. Was looking at Evolution because it appears as if Fuel-Moto says they are interchangeable. Didn't know they only hold 120ish though. I did however Find a good picture representing the difference between Evos and stock. To be honest they look the same as Barnett? It's hard to tell exactly but definitely more area of contact than stock.

You can run an EVO-Industries hub & plates (https://www.evolution-industries.com/shop/harley-davidson-motorcycle-parts/clutch-kits-baskets-assemblies-components/clutch-kits/stage-1-clutch-kits/) with the shell you have.

It appears the basket is sold with the starter gear and ring gear.  Each have optional tooth count available. If you change the starter ratio it comes with the appropriate starter pinion gear.  Changing the drive sprocket tooth count simply alters the drive ratio  but it will also change the chain length requirement.  You can use your own hub but require their smaller diameter hub if you choose to use the more robust clutch fiber disc setup that uses mere area as in Wookie's pics.

As Rigid stated, alternatively you can use your basket assembly and add only the hub and plates with the wider discs.  The basket dimension does not change but the Evo Industies unit is much stronger to avoid fracture when putting more power through it.

Post by: CarlosGGodfrog on January 31, 2022, 07:52:33 AM
The reason I was looking for a basket, is that I have already changed my drive ratio to 3.37 from the stock 3.16. Simple change of compensator and drive assembly from a Softail style to a EG style. No chain length change. Since I have a new stock drive assembly, changing the ring gear to an 84 tooth is a no brainer. I just want to use a stronger basket. My bud owns a fab shop, so drilling out the rivets on a basket and putting a stronger basket on, even if new holes must be drilled is not difficult. I am not familiar with clearance issues, etc. I even thought of shrink fitting a support ring on the stock basket like automotive transmission shops do on drag cars, or making one out of steel.
