NOTE:
During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE:
Remove the cylinder heads before removing the crankshaft. Failure to do so can result in engine damage.
NOTE:
If the components are to be reinstalled, they must be installed in their original location. Mark the components for installation into their original location.
NOTE:
Refer to the exploded view under the Engine Component View in the Description and Operation.
- 1.WARNING: Do not breathe dust or use compressed air to blow dust from storage containers or friction components. Remove dust using government-approved techniques. Friction component dust may be a cancer and lung disease hazard. Exposure to potentially hazardous components may occur if dusts are created during repair of friction components, such as brake pads and clutch discs. Exposure may also cause irritation to skin, eyes and respiratory tract, and may cause allergic reactions and/or may lead to other chronic health effects. If irritation persists, seek medical attention or advice. Failure to follow these instructions may result in serious personal injury.NOTE: Loosen the bolts evenly to prevent clutch pressure plate damage.NOTE: If the parts are to be reused, index-mark the pressure plate to the flywheel.
Remove and discard the pressure plate bolts.
