Method B

WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
  1. Wipe all of the oil off of the balance shaft journal and the bearing surfaces.

    Important:  Do not rotate the shafts after the gauging plastic has been placed on the journals. If the shafts are rotated the gauging plastic will smear, making the readings wrong.

  2. Place a piece of gauging plastic across the entire journal surface.
  3. Assemble the upper and lower housings and tighten all the fasteners in sequence to specification.
  4. Disassemble the housing.
  5. Measure the flattened plastic at the widest point with the scale on the gauging plastic package. The plastic will be wider on the journal end away from the counter weight. This is because the journals are purposely tapered.
  6. Remove all of the gauging plastic from the bearing and or journal.
  7. Compare the measurements to engine specifications.
