Stagger piston rings so that no ring gap is directly over wrist pin bore, and no ring end gaps are aligned over each other. Identification markings on rings should face top of piston. The keystone ring goes in the top ring groove. Follow the directions on each piston ring packet. Refer to Figure 5-15. 1. To prevent distortion, use the proper size piston ring expander (PT6587) to place rings in piston grooves. Figure 5-16 — Ring Gap Locations [212 LP & NP] CONNECTING ROD ASSEMBLY TO PISTON Refer to Figure 5-17. 1. Install a retaining snap ring in one of the piston pin retaining grooves. 2.
Position connecting rod in piston assembly. Make sure that the side of the rod marked FRONT is facing forward. Ensure that two- piece piston identification marks and connecting rod identification marks indicate that piston and rod are matched. They must be returned to same cylinder from which they were removed. Figure 5-15 — Piston Ring Expander PT6587 Page 5-17 200 BENCH PROCEDURES
