Signal12 Posted August 2, 2023 Report Share Posted August 2, 2023 Ladies and Gents.. 76 B210 Sedan Coupe here and I’m having an issue with the front hub. Took it all apart and now I can’t get the rotor to separate from the hub. The rear mounted bolts came off easy enough, but its the damn thing almost appears as though it’s 1 piece. Thoughts?

datzenmike Posted August 2, 2023 Report Share Posted August 2, 2023 Yes it does come apart. Clamp the hub in a vice and tap around the circumference of the rotor forcing it off to the right. If keeping the rotor avoid damaging the pad surface. Round and round and it will slowly work it's way off. Quote Link to comment

datzenmike Posted August 2, 2023 Report Share Posted August 2, 2023 Use a brass hammer or something softer than steel. Quote Link to comment

Over time, rust and corrosion can cause the rotor to stick to the hub. Try using a penetrating oil or rust penetrant spray around the edges of the rotor where it meets the hub. Allow it to sit for a while to help loosen the bond. Applying gentle heat to the area where the rotor meets the hub can help expand the metal slightly, making it easier to separate the two. Be cautious not to overheat the components, as excessive heat can cause damage. Quote Link to comment
jagman Posted August 5, 2023 Report Share Posted August 5, 2023 I have used two wedges between the rotor and hub to separate them. gentle tapping on the wedges will normally put enough pressure on them to get them apart. Quote Link to comment
datzenmike Posted August 5, 2023 Report Share Posted August 5, 2023 You could use a lot of heat if you want. Rotors are used to it. Quote Link to comment
yenpit Posted August 6, 2023 Report Share Posted August 6, 2023 Use penetrating oil to soak, as Nikkil suggested. Then heat around the inner area of the ROTOR with map gas (yellow bottle, hotter than blue bottle propane). Be careful to NOT breathe the fumes of the burning penetrating oil, as they are caustic! Try NOT to focus flame on the hub...........you want to heat the rotor to expand it ever so slightly. I prefer to PRESS the hub out, as beating it with a hammer CAN damage the lip of the hub. As datzenmike suggested, use a BRASS hammer! I have seen MANY 510 hubs beat to snot on that lip, a few damaged so badly it was scrap metal to me! Quote Link to comment
thisismatt Posted August 6, 2023 Report Share Posted August 6, 2023 Probably could have left it all soaking in some phosphoric acid and been done by now 😛 Quote Link to comment
datzenmike Posted August 6, 2023 Report Share Posted August 6, 2023 As with my Maxima hubs, last summer I stripped a set of '81 zx hubs. I tapped around and around on the top hat of the rotor. Not too hard, just kept going and it slowly split apart and slid off. No big deal. Quote Link to comment
Signal12 Posted August 16, 2023 Author Report Share Posted August 16, 2023 I ended up taking them to the machine shop… They were rusted rusted….but they’re apart. Thanks for all the advice….I’m sure ill be back for more. Quote Link to comment
