Stan's Neo Rear Hub Service

Video guide for disassembly, bearing replacement, and reassembly of Neo and Neo Ultimate Freehubs
==============
What you will need:
Smooth-jawed pliers or an axle vise
Blind bearing puller
Hammer
Punch
Bearing press with appropriate drifts
Small flat-tipped screwdriver
Assembly grease
Freehub grease
Cassette tool
Chain whip
Toothbrush
Gloves
================
Your freehub body should be removed a few times per year to be cleaned and lubricated. In this video, we will cover the complete disassembly and service of the freehub body.
Before removing your freehub body, remove the cassette from the wheel.
To remove the freehub body, grip the body with your hand and pull away from the hubshell.
The axle may pull out of the hub with the freehub body. If this happens, pull the axle out of the freehub body and set aside for later use.
The red freehub spacer may remain against the drive side hubshell bearing. If so, remove it and set it aside for later use.
If the axle remains in place, remove it from the shell and set aside along with the red freehub spacer.
If any of these pieces are too difficult to remove by hand, you may use an axle vise or smooth-jawed pliers to remove them
Remove the comolded seal from the hubshell with a small flat-tipped screwdriver.
Clean the drive ring, and co-molded freehub seal with isopropyl alcohol, and a clean rag and set aside for later use.
Wipe excess grease from your freehub body.
Using a small flat-tipped screw driver, pry the pawl retaining ring off of the freehub body.
Slide the pawls, and then pawl springs, out of their respective pockets in the freehub body.
Thoroughly clean the pawls, pawls springs, and pawl pockets in the freehub body with isopropyl alcohol, a toothbrush, and a clean rag.
To remove the bearings, start by removing the rubber seal adjacent to the outboard bearing with a small flathead screwdriver
Insert 15mm Sealed Bearing Extractor into one of the freehub bearings. Tap Extractor and bearing out of hub shell using punch and hammer. Perform this step over a rag as the bearing, extractor, and inner axle sleeve will fall from the hub shell when the bearing is removed.
Thoroughly clean freehub body bore, and freehub sleeve, with isopropyl alcohol and a clean rag.
Apply a thin layer of grease to the bearing bore
Press the bearings in, one at a time, using a bearing press and the appropriate drifts. Don’t forget to install the axle sleeve between the two bearings.
Reassemble the freehub by first installing the pawl springs, and then the pawls.
Install the pawl retaining ring into its groove in the freehub body.
Small grooves and burrs from the cassette's contact with the freehub will not affect hub performance, and can be gently filed down to allow easier cassette installation
Apply a thin layer of freehub grease to the drive ring and freehub pawls
Reinstall the co-molded seal to the hubshell
Reinstall the axle and freehub body spacer
Install the freehub body onto the axle and insert into the hubshell by gently pressing down and twisting clockwise
Lastly, reinstall your endcaps

Nicely done

[@sgtmurg]

Where can I buy that same bearing press that you have and how do I know what the appropriate drift is for the hub? I have Stans flow s1 wheels

[@CactusJackSlade]

I'd like to know too..... I ended up using a socket the correct size with all thread passed through the socket and washers on the other end and nuts on both ends.

[@blakee9690]

What bearings does this use?

[@maximilianofabriciovalleze119]

Tengo la misma pregunta

[@andrewc1058]

My free hub is completely stuck, any tips?

[@andrewc1058]

I was able to get it off by hammering the axle out of the hub.

[@jeffblau]

Did you get any tips? My axle and freehub are both much harder to get disassembled. I ended up having to bang it out with a mallet.

[@andrewc1058]

Jeff Blau No tips, just did the same thing as you.

[@allez6]

​@@jeffblau Same here. Mine was beyond tight. Freehub wouldn't come off. Everything was SO tight the free hub bearing actually came out when banging the opposite axle! I ended getting free hub off in the end but bearing was stuck on axle. I just pressed the bearing back into freehub using drifts and mallet. I then finally pushed the axle off the hub using mini crow bars for leverage. The axle and bearing was that tight. Now, I don't know how to reinsert. I'm thinking of using wet n dry sand paper to shave axle down a little. What did you do in order to reinsert the axle and freehub body back on without resorting to more malleting? I cannot do this with the free hub needing to engage with the hub splines.

And if you have none of the tools listed, you'll need a bike shop close by!

[@Soso64bit]

or $500+ to purchase said tools ... XD

[@m00nchildblues]

Vince i bought 35$ red press tool and that's all u need to buy. If u have at least a 100pc socket set, there's all the drift fittings u need! New bearings,grease,towels and some patience and TH-cam and I just saved over 200$ in LBS labor!
