This is the common "rotor-over-hub" conversion listing of parts for our 90-93 Accords.
98-99 Acura 2.3CL front hub assemblies
90-93 Accord wheel bearing assemblies
98-02 Accord or 98-99 Acura 2.3CL front rotors
90-93 Accord pads (for Akebono or Nissin front calipers)
retain stock caliper
Now, there was speculation on www.accordinglydone.com on this large thread they had dedicated to this and the 11.2" front brake upgrade. Anyhow, just to clarify things, the 1998-2002 Accord front hub assemblies will NOT work for this conversion. I ordered these 98-02 Accord front hubs, thinking it was a cheaper alternative to the 98-99 Acura 2.3CL front hubs to see if they would work. Well, I ended up ordering the 98-99 Acura 2.3CL hubs and now have them side by side.
The differences and why the 98-99 Acura 2.3CL hubs work:
- both have same bolt pattern
- both have same hub flange outer-diameter
- both have same set screw hole pattern
- both appear to have same spline count & pattern from outside of hub, looking in
- differences lie in the turned shaft that is pressed into the wheel bearing
98-99 Acura 2.3CL hub:
- inner spline side is wider
- turned shaft outer-diameter is 1 15/16"
- turned shaft length is 1 5/8"
98-02 Accord hub:
- inner spline side is not as wide
- turned shaft outer-diameter is 2 1/16"
- turned shaft length is 1 9/16"
* If I get time, I'll take a few comparison pics. *
ROH with 11.1/282mm Rotors
Just did this DIY for my local forums here in Australia and did a search on here to see if there was one done. Couldn't find one done already which I couldn't believe. Anyway, if there is already one done just point me to it and I'll get rid of this. Suggestions welcome. Hope this comes in handy to someone. It was alot easier than I was expecting it to be. Mainly because of no ball joint separations.
Aim: Rotor over hub conversion with prelude 282mm rotor and caliper upgrade.
Required:
- New or re-use CB Accord front wheel bearings. (If re-using your old ones they need to be pressed out from the hub)
- 98 Acura CL 2.3 front wheel hubs (pressed onto bearings)
- 94 Prelude VTIR 282mm front brake rotors
- 23T Prelude caliper brackets
- 97 Prelude calipers/92 Accord wagon calipers with brake pads to match
Steps:
1. Jack up the car safely and remove the front wheels.
2. Remove the axle nut and push the drive shaft back through as far as it will go. You need this clearance to get the bolts off that hold the bearing onto the knuckle.
3. Remove the 12 point bolts holding the bearing to the knuckle from behind the knuckle. You'll probably need to use a ring spanner because its pretty tight in there.
4. Ideally you would now use a slide hammer to get the bearing off the knuckle. It isn't pressed in but it is pretty tight. We just used a big screw driver and bashed it in between to wedge it out. Once loose remove it from the knuckle.
Old vs New bearing pressed into new hub.
5. Fit the new bearing and hub to the knuckle and screw the bolts in from behind the knuckle again. The bearing will be tight again so use the bolts to tighten it in, in a criss-cross pattern.
6. Slide the new rotor on over the hub and tighten the set screws.
Old Vs New
7. Fit the new caliper bracket, pads and caliper.
Finished. (Ignore the writing the calipers are from a BB6 Prelude)
8. Fit the brake line to the new caliper and bleed the system.
