Serial 35601766 falls in the 3056E 35600001-up engine range. Use Cat publication RENR2400 for the component procedures and SENR3130 only where no specific torque is published. Relevant values are 78 N·m for the cam gear bolt, 44 N·m for the idler retainers, 115 N·m for the crank pulley bolts tightened evenly, and 22 N·m for the water-pump and front-cover bolts. Idler end play is 0.10–0.20 mm and cam-to-idler backlash is 0.052–0.107 mm. Before removing the injection pump, set No. 1 at TDC compression and lock both the crankshaft and pump according to the FIP procedure. Because different pump arrangements use different mounting values, follow the attached FIP sheet for that torque rather than assuming a standard value. Nige’s answer is fundamentally correct: those component-specific sheets take precedence over a generic bolt chart. “perkapillar” is an appropriate nickname: the Caterpillar 3056E is essentially the Cat-branded version of the Perkins 1106C-E60TA.
