4. Setup and Installation
Follow these steps to install the kit components into your John Deere D or E170 lawn mower. Refer to your mower's service manual for exact locations of components if unsure.
4.1. Air Filter Installation
- Locate Air Filter Housing: Identify the air filter housing on your John Deere D or E170 mower. It is typically a plastic casing near the engine.
- Remove Old Air Filter: Open the air filter housing cover. Carefully remove the old air filter element. Note its orientation.
- Clean Housing: Clean any dust or debris from inside the air filter housing using a clean cloth or compressed air.
- Install New Air Filter: Insert the new air filter into the housing, ensuring it seats properly. The green foam side should face outwards.
- Secure Cover: Close and secure the air filter housing cover.
4.2. Fuel Filter Installation
Caution: Fuel is flammable. Work in a well-ventilated area and have a fire extinguisher nearby.
- Locate Fuel Line: Identify the fuel line running from the fuel tank to the carburetor. The fuel filter is typically inline on this hose.
- Drain Fuel (Optional but Recommended): If possible, drain the fuel tank or clamp the fuel line before the filter to minimize fuel spillage.
- Remove Old Fuel Filter: Use pliers to loosen and slide back the existing hose clamps (if present) on either side of the old fuel filter. Carefully twist and pull the old filter off the fuel lines. Expect some fuel to leak.
- Install New Fuel Filter: Note the flow direction arrow on the new fuel filter (if present). It should point towards the carburetor/engine. Push the fuel lines onto the new filter's inlets/outlets.
- Secure with Clamps: Slide the provided new hose clamps over the fuel lines and position them securely over the connections to the fuel filter. Tighten the clamps with pliers or a screwdriver until snug, but do not overtighten.
- Check for Leaks: After installation, allow fuel to flow and check for any leaks around the new fuel filter connections.
5. Operating After Installation
Once the kit components are installed, perform the following checks before operating your lawn mower:
- Visual Inspection: Double-check all connections for tightness and ensure no tools or loose parts are left on the mower.
- Fuel System Check: Confirm there are no fuel leaks around the new fuel filter.
- Start Engine: Reconnect the spark plug wire. Start the mower and allow it to run for a few minutes. Listen for any unusual noises or observe any performance issues.
- Test Operation: If everything appears normal, you may proceed with normal operation.
6. Maintenance
Regular maintenance of these components ensures optimal performance and extends the life of your lawn mower.
- Air Filter:
- Inspect the air filter every 25 hours of operation or annually, whichever comes first.
- Clean the foam pre-filter (if applicable) with warm, soapy water, rinse thoroughly, and allow to air dry completely before reinstallation.
- Replace the air filter element if it appears excessively dirty, damaged, or clogged.
- Fuel Filter:
- Inspect the fuel filter annually or every 50 hours of operation.
