Step-by-Step Oil Filter Replacement Guide

Replacing the oil filter on your Kohler 7000 series engine is a straightforward process that most equipment owners can perform themselves. Follow these steps for a successful oil change and filter replacement.3,4

Tools and Materials Needed:

New Kohler 7000 series oil filter (12-050-01-S or equivalent)
SAE 10W-30 engine oil (2 quarts)
Oil drain pan
Socket set or wrench
Funnel
Clean rags
Gloves1,4

Replacement Procedure:

Warm Up the Engine: Run the engine for 5-10 minutes to warm the oil, making it easier to drain completely.
Position Equipment: Place the equipment on a level surface and engage the parking brake. For lawn tractors, raise the cutting deck to its highest position.
Drain Old Oil: Locate the oil drain plug on the bottom of the engine. Place the drain pan under the plug and remove it carefully. Allow all oil to drain completely.
Remove Old Filter: Locate the oil filter, which is typically mounted on the side of the engine. Use an oil filter wrench if necessary to loosen and remove the old filter. Be prepared for some oil to spill when removing the filter.
Prepare New Filter: Before installing the new filter, apply a thin layer of clean engine oil to the rubber gasket on the new filter. This ensures a proper seal and makes future removal easier.
Install New Filter: Hand-tighten the new oil filter until the gasket makes contact with the engine surface. Then tighten an additional 3/4 to 1 full turn by hand. Do not use tools to tighten the filter, as this can damage the gasket.
Reinstall Drain Plug: Clean the drain plug and reinstall it with a new washer if necessary. Tighten securely but do not overtighten.
Add New Oil: Using a funnel, add approximately 1.5 quarts of SAE 10W-30 oil to the engine. Check the oil level with the dipstick and add more oil as needed to reach the full mark.
Check for Leaks: Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any leaks. Turn off the engine and recheck the oil level, adding more if necessary.
Dispose of Old Oil Properly: Take the used oil and filter to a recycling center or auto parts store that accepts used oil.3,4
