Ford Boss 302 Engine Safety Wiring Procedure - Oil Pump, Main Cap & Pan Baffle
Service manual page explaining engine safety-wiring procedures with arrangement figures.
This is a single page from a vintage engine maintenance manual, headed "MAINTENANCE," covering the topic of safety wiring on engine fasteners. The text instructs that whenever safety wiring is removed it must be replaced to help prevent loosening of attaching nuts and bolts, specifying the use of .032 inch diameter stainless steel annealed safety wire installed as shown in the accompanying figures. Three black-and-white photographs illustrate the procedure: Figure 51 shows the safety wiring arrangement for the oil pumps and rear main bearing cap on the underside of an engine block; Figure 52 shows the safety wiring arrangement for the oil pan baffle inside the oil pan; and Figure 53 shows a special safety-wiring tool (twisting pliers) in use, with the note that the wire must be turned to the right — in a tightening direction — around the bolt head. The page gives no year, model, engine, part numbers, or torque values, but from the album context it is part of a multi-page performance/racing engine maintenance document (other album files reference "inline B302"). It teaches a reader the correct wire gauge, material, locations, and wrapping direction for safety wiring critical bottom-end and oiling-system fasteners.
