Caltric Starter for John Deere 100-Series & L111 L118 Tractors — 16-Tooth Steel Gear, Direct Replacement

The Caltric starter is a direct-replacement electric starter engineered to fit select John Deere and Briggs & Stratton engines, featuring a reinforced 16-tooth steel drive gear for reliable engagement.

Designed as a drop-in replacement for a range of lawn tractor and small-engine applications, this Caltric starter is sized and configured to match common mounting patterns, electrical connections and gear profiles found on many John Deere 100-series tractors, Cub Cadet models and Briggs & Stratton engines. The unit simplifies swap-outs with clear dimensional specs and compatibility notes, making it a practical choice for do-it-yourself repairs or shop technicians who need a cost-effective alternative to OEM parts.

Which machines will this Caltric starter fit?

This starter fits a number of John Deere models (including many 100-series tractors and L111/L118 applications) as well as specific Cub Cadet and Briggs & Stratton engines. Compatibility is based on engine model, bolt pattern and starter gear teeth count.

• John Deere: many 100 Series (D125, D130, D140, D150, D160, D170), L111, L118, X330, Z225, Z235, Z255, Z525, Z535, Z665, S220 and others.
• Cub Cadet & Briggs & Stratton engine compatibility listed in product features (7HP–18HP ranges and specific 12–14hp engine variants).
• Cross-reference part numbers such as MIU13772, AM37352, LG497595 and Briggs part numbers (391423, 497594, 497595) before ordering.

How does the 16-tooth improved steel gear affect performance?

The starter’s 16-tooth steel drive gear offers stronger tooth engagement and improved wear resistance compared with softer or plastic gears. That translates to a longer service life under frequent use and better resistance to chipping during starter engagement.

• Steel gear resists wear and deformation better than plastic alternatives.
• 16 teeth match the intended flywheel ring gear profile for reliable engagement.
• Improved durability reduces the chance of premature starter failure.

What are the physical and electrical specifications to verify fit?

Confirming dimensions and mounting pattern avoids returns and fitment issues. This Caltric starter includes precise measurements and commonly used part numbers for cross-referencing with the OEM unit.

• Overall length: 170 mm (6.7 in); width and height: 78 mm (3.1 in).
• Mounting hole distance: 58 mm (2.29 in)—match this to your tractor’s starter flange.
• Compare electrical terminals and the starter picture to your existing unit before installation.

What comes with the purchase and what should I check before installation?

The starter ships as a single replacement unit intended to replace the original starter assembly. Before installing, visually compare the posted product image to your old starter and verify bolt pattern and electrical connector types.

• Order includes: 1 x Caltric starter unit with 16-tooth steel gear.
• Check compatibility lists and part numbers (Briggs & Stratton, Cub Cadet, John Deere cross-references) against your machine’s manual.
• Inspect flywheel ring gear condition; damaged ring gears should be addressed before installing a new starter.

Who is this for: This Caltric starter is aimed at homeowners, landscapers and small-engine repair shops needing a robust, economical replacement for failing starters on select John Deere garden tractors, Cub Cadet machines and compatible Briggs & Stratton engines. It’s best for users comfortable comparing part numbers and dimensions to their original starter and who want a durable steel-gear option rather than a plastic-gear unit. If you’re unsure about fitment, compare the photos and measurements provided to your current starter or consult a technician before ordering.
