Fitting Pistons
Production and service pistons have same nominal weight and can be intermixed without affecting engine balance. DO NOT cut oversized pistons down as balance will be affected.
CAUTION:
To prevent possible cylinder block and/or main bearing damage, DO NOT
use attaching bolts to pull main bearing caps into position. Use a brass or leather mallet to tap main bearing caps into position. Tighten in proper sequence. See TORQUE SPECIFICATIONS
