Illustration 2 g01408564
204-0712 Bolt (B) 30 mm (1.18 inch)The two bolts that are Type 1 are 30 mm (1.18 inch) long. Marks on the head of the bolt represent the grade of the bolt. These markings can be seen in Illustration 1 and Illustration 2. The 6V-2317 Bolt is being replaced by 204-0712 Bolt . The 204-0712 Bolt has a torque value of 40 8 N m (30 6 lb ft). 13 bolts are required for the installation of the front housing.Note: Check availability of the kit which includes the gasket and the bolts.Type 2
Illustration 3 g01408555
6V-5219 Bolt (C) 40 mm (1.57 inch)The 6V-5219 Bolt is 10 mm (0.39 inch) longer than the 204-0712 Bolt . The longer bolt is needed due to a deeper counterbore and the tapped hole. Do Not use the 204-0712 Bolt or the 6V-2317 Bolt . This could result in damage to the threads. The torque on the 6V-5219 Bolt bolt is 35 8 N m (26 6 lb ft). 13 bolts are required for the installation of the front housing.Remanufactured Engines
