Twin turbo mentioned laser aligning a drivetrain and this would have saved me many hours of doing it the old fashion way.
The only way I knew at the time was dropping plumb lines from the front of the crank right behind the harmonic balancer, another on on the output shaft of the tranny, another on on the pinion yoke and finally one dropped from the center of the hole on the spring mount. The cover has a little hole drilled for the head of the through bolt on the spring to hold it in alignment.
I dropped these 4 plumb lines then took a string and with a large loop on the end put it around the front sway bar. I then used a set of folding steps out behind the car and tied the other end of the string to these steps.
I then had to juggle the string front and back so it just about but not quite touched the front harmonic balancer plumb line and the rear cover plumb line.
You move the front loop along the sway bar and at the same time the steps behind the car.
I wanted these 2 plumb lines about 1/16 off the centerline sting.
When that was done it showed the tailstock and the pinion nose plumb lines were not on the same plane and both needed rotating the motor towards the drivers side and the pinion also towards the drivers side.
We all see this with prying the tailstock over to start the bolts.
It would be so much easier if I knew how to do it with a laser, more accurate too. I have a laser but not the knowledge of how to go about using it for aligning the drive train???
Could you give me a rough run through Marck of how to go about this???
Thanks
