    alpha one w/485 srt 4cyl alinement issue

    So if anybody would decide to chime in, I think I figured that I had to lower it because now it’s smooth as butter, but I’m almost all the way bottomed out lowering it. But I guess it is what it is correct me if I’m wrong.

    alpha one w/485 srt 4cyl alinement issue

    gimbal bearing was stuck. I freed it up before I went into work. I will grease the **** out of it. It is smooth but it just would not rotate. I will raise the motor back up and play with alignment tonight.

    alpha one w/485 srt 4cyl alinement issue

    thanks for the reply Scott, I just do not get it I guess, so it should move as I put the alignment tool in? Is it not set once a new bearing is installed to where the engine is set at?
