Tune Up & Oil Change Kit for John Deere 100 Series Tractor, Fits D105 D110 D125 D130 D140 E100 E140 S130 S140 Z315e Z335e, Maintenance Kit, Includes AM125424 Oil Filter & MIU14395 Air Filter

What It Is

This is a complete tune-up kit for John Deere 100 Series lawn tractors and compatible zero-turn models. It includes an oil filter (AM125424), air filter (MIU14395), and often a spark plug and fuel stabilizer, designed to simplify routine engine maintenance.

Fitment & Compatibility

Before buying, confirm your mower’s exact model and engine type. This kit fits John Deere D105, D110, D125, D130, D140, E100, E140, S130, S140, Z315e, and Z335e models, but only those with the 19–22 HP Briggs & Stratton or Kohler single-cylinder engines. Do not use on Kawasaki or twin-cylinder engines – filter sizes differ. Check your owner’s manual for engine displacement (e.g., 540cc, 725cc) and verify the oil filter thread size (3/4"-16) and air filter dimensions (roughly 5" x 3.5"). The kit is aftermarket, not OEM John Deere, but uses equivalent parts. Measure your old filters against the kit’s specs if unsure.

Key Things to Know

• Quality: Filters are generally well-made, but some users report the air filter foam may be slightly thinner than OEM. Inspect for fit before installing.
• Installation: Easy for DIYers – requires basic tools (socket wrench, oil drain pan, screwdriver). Allow 30–45 minutes for oil change and filter swaps.
• Gotchas: The kit may not include a spark plug (check product description). If it does, verify it matches your engine’s gap (usually 0.030" for Briggs). Also, drain oil when warm but not hot to avoid burns.
• Compatibility risk: Double-check your mower’s engine model number (e.g., 31C707) – the kit is listed for specific 100 Series tractors, but variations exist. Cross-reference with OEM part numbers AM125424 and MIU14395 on John Deere’s site.

Should You Buy It

Buy this kit if you own a common John Deere 100 Series with a single-cylinder Briggs or Kohler engine and want an affordable, all-in-one solution for routine maintenance. It’s ideal for DIY homeowners who don’t need OEM branding and can verify fitment before purchase. Avoid if you have a twin-cylinder or Kawasaki engine, or if you prefer exact OEM parts for peace of mind.
