Engine Removal (Fig. 13) 1. Remove engine mounting plate assembly from machine (see Engine Mounting Plate Removal in this section). 2. Loosen CVT drive belt guides. Rotate driven clutch and route drive belt over the driven clutch. Remove belt from the drive clutch (see Drive Belt Service in Service and Repairs Section of Chapter 7 – Drive Train). 3. Loosen hydraulic steering pump and remove pump drive belt from pulleys. 4. Loosen and remove three (3) remaining flange head screws and flange nuts that secure engine to engine mounting plate. Remove engine from mounting plate. 5. If needed, remove drive clutch from engine crankshaft (see Drive Clutch in the Service and Repairs Section of Chapter 7 – Drive Train). 6. If needed, loosen set screws and remove steering pump pulley from engine crankshaft. Locate and retrieve key. Engine Installation (Fig. 13) 1. Make sure that all parts removed from the engine during maintenance or rebuilding are reinstalled to the engine. 2. If steering pump pulley was removed from engine, position key into keyway of engine shaft. Apply anti– seize lubricant to shaft and key. Assemble pump pulley over key and shaft with hub on pulley away from engine. 3. If drive clutch was removed from engine, reinstall clutch to engine (see Drive Clutch in the Service and Repairs Section of Chapter 7 – Drive Train). 4. Secure engine to the mounting plate with three (3) flange head screws and flange nuts. The flange head screw position under the starter motor should not be used because it is used to secure the negative (–) cable to the engine. 5. Install steering pump drive belt to pump pulleys. Position pump pulley on engine so pulleys are aligned. Apply Loctite #242 (or equivalent) to pulley set screws and secure pump pulley to engine crankshaft with set screws. Adjust pump drive belt tension (see Operator’s Manual). 6. Place CVT drive belt around drive clutch. Rotate driven clutch while routing the belt onto the driven clutch. Adjust belt guides (see Drive Belt Service in Service and Repairs Section of Chapter 7 – Drive Train). 7. Install engine mounting plate to machine (see Engine Mounting Plate Installation in this section). Kohler Gasoline Engine Multi Pro 1200/1250 Page 3 – 15 Kohler Gasoline Engine
