3208 Engines With Front Power Take-Off AdapterSUPPLEMENT: 01/11/82SERVICE MAGAZINE, OCTOBER 5, 1981, PAGE 5.In the last supplement on Page 5, the part number for the plated bolt is not correct. The correct part number is 5P4135 Bolt.--------------- END SUPPLEMENT ---------------A change has been made to the bolt torque specifications for the front crankshaft pulley and front power take-off adapter on 3208 Engines with 130 to 157 kW (175 to 210 hp). These engines when used in special applications where a front power take-off is used must have a strong pulley to crankshaft junction. The increased bolt torque will make this junction stronger.
The new torque specification for the crankshaft pulley bolt is 950 + 50 N m (700 + 37 lb ft). The new torque specification for the bolts that fasten the power take-off adapter to the crankshaft pulley is 55 + 7 N m (40 + 5 lb ft).
