Engine Building Tip
I am in the process of rebuilding a '88 TII engine. In the process of finding a new rear rotor and housing I came across something I have never seen on here before.
As you know, Mazda balanced each rotor at the factory. Due to slight variations in the balancing process, each rotors weight varies slightly. Mazda designates this variation by stamping a letter, (A-E), on the gear side of the rotor. According to Mazda the rotor weight should not vary more than 2 letters in an engine. Ideally, you should have matching rotors. I did verify this with Henry at Mazdatrix. If this is common knowledge, sorry to take up the bandwidth, just wanted to let everyone know.

i noticed the letter before, but never gave them any thought further than the acknowledgement ...

Make that 2. I never knew that either. I got rotors laying all over the place. I saw the letters, but I was more worried about the numbers for the side and apex seals. Thanks for the enlightenment.
