- 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
Maybe I missed something but I’m curious what the purpose of removing the bearings from the freehub body. Is it implied that if the bearings were dragging you would replace them? Removing them just to grease where they sit in the shell is pointless if the bearing are running smooth correct? Also does Stans recommend removing the bearings and removing the seals, repacking and reinstalling when servicing?
Thanks for the great video and any additional info you can provide.
Removing the bearings from the freehub body is only necessary if the bearings need to be replaced. There is no need to regularly remove the bearings if they are still in good shape.
I installed the SRAM GX DUB Eagle Crankset full component set. In doing so I had to purchase a Stans Free Hub XD Driver. Everything is installed but the freewheel does not spin freely when I stop pedaling. Any thoughts?
Best way to remove thru axle in my stans freehub? I pulled out free hub but axle is stuck.i don't want to damage. Any ideas?
Tap with a rubber mallet
freehub grease rather than oil? Why some say oil rather than grease? kind of grease you recommend?
Hey m00nchildblues
, using oil in a freehub requires a lot more maintenance, so grease is preferred. We recommend using the lightest weight grease available.
So there is nothing that retains the freehub in place other than the QR axle? Every time I take my rear wheel off everything falls apart. Am I missing something?
The hub axle sleeve is what holds everything together. It's independent of the wheel mounting axle.
My free hub is completely stuck, any tips?
My free hub body will not come out no matter how hard i pull. What am I doing wrong?
Hey Nathan! If your freehub isn't sliding off the axle relatively easily, then it sounds like there might be something else going on. Get in touch with us at tech@notubes.com and we'll help you out!
Did the video skip where he greases the drive ring?
Hey Dustin! It's mentioned at 4:00 to apply a thin layer of freehub grease to the pawls and drive ring. Just enough to thinly coat everything will do! A little bit goes a long way!
can you use freehub oil instead of grease?
4:40 kinda looked like anti-clockwise to me, but great vid nonetheless.
You are absolutely right! We meant counter-clockwise!
My freehub has 3 bearings. Is this normal? I cant find that in the tech documents
The Neo SpeedSync and Durasync freehubs will have 3 bearing. This video has the original Neo 2 bearing freehubs. Same process to service them.
can you convert a boost 148 hub to a boost 141 qr with endcaps?
Hey David, you can convert a boost 148 hub to a boost 141 qr hub. All that is required is a set of end caps. ZH0780 - 6 bolt hubs. ZH0957 for - Centerlock hubs. Please contact tech@notubes.com with any questions.
