2-25 1955 BUICK ENGINE MOUNTING ADJUSTMENT

The 1955 Buick engine and transmission assembly must rest in a normal position which does not impose any side strain on the three rubber mounting pads. The following procedure may be used to obtain proper adjustment of the 1955 Buick engine mountings.

  1. Tighten the 1955 Buick engine front mounting pad stud nuts, under the supports on frame, and tighten the mounting bracket to crankcase bolts. Loosen the upper bracket to mounting pad bolts.
  2. Disconnect torque tube from torque ball.
  3. Tighten transmission support to frame bracket attaching bolts.
  4. Tighten transmission mounting pad to transmission support and to the transmission rear bearing retainer.
  5. Tighten thrust pad to thrust plate stud nuts (rear) and loosen thrust pad to transmission support stud nuts (front). Remove shims located between thrust pad and transmission support. See figure 2-41.

  7. Tighten thrust pad front stud nuts and connect torque tube to the torque ball.
  8. Tighten the front mounting pad to bracket bolts.

 

2-26 1955 BUICK FLYWHEEL REPLACEMENT

Replace 1955 Buick Flywheel and Check Run-out on Dynaflow Engine

  1. Remove the Dynaflow transmission then remove the flywheel which is located in a definite position on the crankshaft flange by means of one dowel.
  2. Inspect flywheel. If ring is damaged replace flywheel because the ring is welded in place and not furnished separately. If flywheel is cracked at crankshaft bolt holes refer to subparagraph c. below.
  3. Check for burrs around drilled holes in crankshaft flange and face of flywheel to be installed; remove any burrs with a mill file, then install flywheel and tighten bolts evenly to 50-55 ft. lbs. torque.
  4. Mount Dial Indicator KM0-30-B with Sleeve KM0-30-K and clamp KM0-30-G as shown in figure 2-42, so that stem of indicator bears against the ground surface of flywheel at inner side of the large holes.
