Here are some tips for looking after your HTZ Hubs
Let’s start by looking at what you need for the job, and today I’m gunna be using;
*A 12mm Allen Key
*A 17mm Cone Spanner
*A torque wrench and 17mm crows attachment
*A bearing press kit
*A long and thin zip tie
*A soft faced hammer or mallet
*A medium sized drift
*Whatever you need to remove your cassette
The replacement bearing sizes are 6902 for the front hub, and 6903 for the front hub.
- Rear Hub -
The first thing you wanna do is remove the cassette to give full access to the hub. You could also remove the disc rotor to minimise risk of contamination with grease, but it’s not necessary. Then you wanna remove the non drive side end cap. It’s not threaded so it should just pull right off. Then, insert the 12mm allen key into the axle to hold it steady, and use a 17mm cone spanner to remove the drive side end cap. It’s got left hand thread, so you’ll need to turn it clockwise. Now you can pull the freehub body off and put it somewhere safe.
Now you’re ready to remove the axle and bearings using a soft-faced hammer.
Tap the non drive side of the axle first to push out the drive side bearing. Pull the bearing off the axle and put it back in to tap the non drive side bearing out. Now that it’s fully disassembled, give all parts a good clean and inspect for damage or wear. Once you’re happy that everything is ready to go, it’s time to start reassembly. Lightly grease where the bearings are going to sit inside the hub, and then use the appropriate bearing press spacer to install the non drive side bearing.
Remove the press, lightly grease the axle, and slide it in from the drive side making sure it’s the correct way round. The short end goes to the non drive side. Now you can slide the second bearing over the axle and use an over-axle kit to press it into place.
Now it’s time to prepare and grease the freehub body, and we recommend Dumonde Tech Pro X freehub grease or similar.
Slide the freehub body over the axle. Rotate the freehub anti-clockwise as you push it on the last few mm. Check the freehub seal is seated correctly and reinstall the drive side end cap using the 12mm allen key and 17mm crows foot attachment on a torque wrench.
The number you’re aiming for is 5-7Nm.
Once that is done, push the non drive side cap back into place, refit the cassette, and you’re good to go.
- Front Hub -
Start by removing both end caps. They’re not threaded so should just pull off. Then you wanna get a medium size drift to tap the bearings out. Use the drift to push the axle sleeve out of the way and make sure you get a nice surface to tap against. Remove one bearing, pull the axle sleeve out, then tap out the second one. Now that it’s fully disassembled, give all parts a good clean and inspect for damage or wear.
Once you’re happy that everything is ready to go, it’s time to start reassembly.
Lightly grease where the bearings are going to sit inside the hub, and then use the appropriate bearing press spacer to install the non drive side bearing. Pop the axle sleeve into place, and then install the second bearing. The last thing to do is to push the end caps back into place and you're good to go.
