Fitting Pistons

Determine cylinder taper, wear, out-of-round and piston clearance. For specifications, see CYLINDER BLOCK under ENGINE SPECIFICATIONS. If taper or out-of-round are not within limits, hone or bore cylinders for installation of new pistons.

NOTE: Bohn or Zollner pistons are used in 6.2L. Each require different clearance specification. Piston can be identified by letter stamped inside of piston skirt area. Letters "B" or "Z" are used for piston identification.
