With the crankshaft, camshaft and auxiliary driveshaft in place, install the timing gear cover. Remove the injection pump cover (if installed) from the timing cover to allow access to the injection pump drive gear during injection pump installation. 1. Apply a light coat of Silastic to the timingcover mounting surface. 2. Position the timing cover on the cylinderblock mounting surface.
Some mounting capscrews cannot be installed until the injection pump is installed. 3. Secure the timing cover to the cylinder block using the mounting capscrews. Torque the capscrews to 40 lb-ft (54 N•m) using torque wrench J 24407, or equivalent. 4. Position the front pedestal mount on the timing cover and secure with the mounting hardware. Torque the front support bracket (pedestal mounting) capscrews to 70 lb-ft (95 N•m) using torque wrench J 24407, or equivalent. Figure 296 — Crankshaft Front Seal Installation 1. Front Cover Seal 2.
