Front Wheel Bearing & Seal Kit (Disc Brake) | Honda CB200 / CB350 / CB360 / CB450 / CB500 / CB550 / CB750
The front wheel bearings on a disc-brake vintage Honda carry your braking and steering loads, and most of these bikes are still riding on the bearings they left the factory with. This kit re-bearings the front disc-brake hub across the CB200 through CB750 family with a matched pair of European made bearings, both hub seals, and the dust-shield O-ring for your model.
Why You Need This
Front wheel bearings are pivotal to a bike's safety and handling, and they wear quietly — a crunchy feel when you spin the wheel, grease weeping past the seal, or lateral play (back-and-forth movement perpendicular to the axle) all mean it is time. Fresh bearings keep the front wheel running true for accurate steering.
The factory bearings are single-sealed — sealed on the outer face only — so once they are dry or notchy, replacement beats trying to repack them. This kit pairs the bearings with new seals and the correct dust-shield O-ring so the hub goes back together sealed up the way Honda built it.
What's in the Kit
- Matched pair of front wheel bearings (6302)
- Wheel bearing dust seal (22 × 36 × 8)
- Speedometer-drive seal (34 × 48 × 7)
- Dust-shield O-ring for your model — selected above

Also fits: The 6302 bearings in this kit carry across the front hubs of many later Hondas as well — CB650, CB750 C/L/F and later K, CB900 C/F, CBX1100, and the GL1000 / GL1100 Gold Wing and GL500 Silver Wing. The bearings and dust seal are shared; pick the closest dust-shield O-ring for your hub.
Pick your dust-shield O-ring above. The O-ring that seals the speedometer-gear retainer plate to the hub changes size across the family, so the kit lets you choose it:
- CB200 / CB200T
- CB350G / CB360 / CB350F / CB400F — 54 mm O-ring (OEM 91307-MB0-003)
- CB450 K3–K7 / CB500T / CB500K / CB550 / CB750 — 58 mm O-ring (OEM 91302-300-000)
Note: The O-ring is a dust shield — it sits sandwiched between the inner and outer plates bolted to the right side of the wheel hub, behind the speedometer drive. The bearing retainer itself is not part of this kit; it is staked into the hub and often gets chewed up coming out, so grab a fresh front hub bearing retainer if yours is damaged.
Installation
Difficulty: Intermediate
The disc hub is the most involved of the front bearing jobs — the bearing retainer is staked (peened) into the hub, so it takes a little drilling and heat to free.
- Pull the front wheel, take off the brake disc, and remove the speedometer gear box and outer plate to reach the bearing retainer.
- The retainer is staked in place. Drill the peen marks lightly with a sharp 1/8" drill bit — just past the surface — soak the threads in penetrating oil, then heat the hub with a heat gun and back the retainer out with the retainer tool. Drive the old dust seal out of the retainer while it is off.
- Drive the old bearings out with a long punch worked at an angle on the inner edge. A hot hub usually gives them up with light taps — if you are swinging hard, add heat.
- Note the distance collar that sits between the two bearings and keep track of it.
- Drop the new bearings in the freezer for a few hours beforehand — it shrinks them slightly for an easier fit. Install the bearing on the lipped-seat side of the hub first, then the collar; that first bearing and the collar set the depth so the second cannot be driven in too far. Drive each one in with a large socket or tube just smaller than the outer race — never press on the inner race or the dust covers.
- Fit the new dust seal into the retainer, put anti-seize on the retainer threads, thread it back in, and re-stake it with a center punch so it cannot back out. Set the dust-shield O-ring between the hub plates, fit the speedometer-drive seal, and repack the speedo gear with fresh grease.

Frequently Asked Questions
Which dust-shield O-ring do I pick?
Match it to your model: CB200 / CB200T use their own O-ring; CB350G, CB360, CB350F, and CB400F use the 54 mm O-ring; CB450 K3–K7, CB500T, CB500K, CB550, and CB750 use the 58 mm O-ring. The bearings and the other two seals are the same across all of them.
Does my bike have a disc or drum front brake?
This kit is for the disc-brake front hub. If you have a drum front, you need a different kit: the CB350 / CL350 / CL360 / CJ360 drum kit or the CB450 K0–K2 / CL450 drum kit. Drum-front bikes have a brake cable and backing plate at the wheel; disc bikes have a caliper and rotor.
How many bearings and seals come in the kit?
Two identical 6302 bearings (a matched pair), a wheel bearing dust seal, a speedometer-drive seal, and one dust-shield O-ring for your model. The bearings ride on a distance collar inside the hub.
Is the bearing retainer included?
No. The retainer is staked into the hub and usually takes damage coming out, so it is sold separately — grab a fresh front hub bearing retainer and, if you do not have one, the retainer tool that backs it out without galling the hub.
Where does the thin O-ring go?
It is the dust shield, and it sits between the inner and outer plates that bolt to the right side of the hub, behind the speedometer drive — not down in the bearing bore. It seals the speedometer-gear retainer plate against the hub.
What else should I do while the front end is apart?
If the caliper is off, a front brake caliper rebuild kit is the time to do it, and fresh front brake pads are cheap insurance (they vary by model). New tapered steering head bearings are another good job with the front end down.
