Reassembly Install Closure Plate Assembly 6. Install closure plate on crankcase. Carefully seat camshaft and crankshaft into their mating bearings. Rotate crankshaft to help engage oil pump and governor gear meshes. 7. Install screws securing closure plate to crankcase. If a thick fl at washer was used on one of screws, install it in number 10 location. Install silver plated (ground) screw in its original location (normally number 4 or 6 location). Torque fasteners, in torque sequence shown to 24.4 N·m (216 in. lb.). Closure Plate Sealant Pattern Install Cylinder Studs Piston/Connecting Rod Details NOTE: Do not reinstall or attempt to reuse any cylinder studs that have been removed.
Discard any removed stud(s) and replace with new. If any of cylinder studs were removed, install new stud(s) as follows: 1. Identify longer threaded end of new stud containing Loctite ® Dri-Loc ® . 2. Tighten nuts together on shorter threaded section, with identifi cation mark on end. 3. Thread end of stud with Loctite ® into crankcase, until an exposed stud height of 75 mm (2 61/64 in.) is obtained. End with dash mark must be out. When threading in studs, use a steady tightening motion, without interruption, until proper height is obtained. Frictional heat from engaging threads may otherwise cause locking compound to set up prematurely. Remove two nuts. 4. Repeat steps 1-3 for each of studs.
Torque Sequence RTV silicone sealant is used as a gasket between closure plate and crankcase. Always use fresh sealant. Using outdated sealant can result in leakage. 1. Be sure sealing surfaces have been cleaned and prepared. 2. Check to make sure that there are no nicks or burrs on sealing surfaces of closure plate or crankcase. 3. Apply a 1/16" bead of sealant to sealing surface of closure plate. 4. Make sure end of governor cross shaft is lying against bottom of cylinder 1 inside of crankcase. 5. If alignment pins were removed previously, install them in their respective locations in crankcase. 62 KohlerEngines.com 66 690 01 Rev.
