new rear rotor + old front rotor = I need opinions
Ok so I have recently discovered that my rear rotor got damaged by a piece of an apex seal and crushed my corner seal. Long story short, the rotor is not useable. I'm going to order a new one from Mazdaspeed motorsports as I'm a member and get some pretty good discounts.
Questions: 1) is there going to be a problem with using a new rotor in one housing and a used rotor in the other housing? 2) Do new rotors come with rotor bearings already installed? thanks guys, Jeremy |
You need to make sure the weights are within spec of each other. Rotors have different weights, A, B, C, D, E I think.
If you have a B rotor, you can use an A, B or a C. if you have a C you can use B, C, D. etc. maybe someone else can give a more precise answer, but the important thing is the weight of the rotor. Rotor age should not matter - if you are rebuilding the motor, I am assuming all apex seals, side seals, coolant seals, etc are going to be replaces. The wear items are the seals themselves, not necessaily the rotor, because the rotor does not actually make contact with the housing, but rather the seals are what gives you compression and forms a tight seal between the rotor and housing |

Luckily the housings were fine but the seal and rotor were both damaged. I've sourced a replacement seal from Hurley (the same seals that I used for the rest of the motor). I am going to be ordering the new rotor today but I wanted to make sure that I order the correct one. I'll see what the weight is on the damaged one. Do new rotors have the bearings already installed or do I have to buy one and the tool and do it myself? |
got any pics of this damaged rotor?

Cant see how you badly damaged the rotor by turning it by hand???

No sense in spending a lot on a new rotor, an engine rotor is one of the few internal pieces that I tend to buy used as long as it's not damaged.....they last forever.
