12V 1.4KW 11T Starter Motor S114-801 for Maxima Infiniti I30 I35

Overview of the S114-801 Starter Motor

The S114-801 starter motor is a 12V, 1.4 kW unit built for Maxima Infiniti I30 I35. It is a reduction-gear starter with a pre-engaged solenoid, assembled to the original mounting flange and terminal positions so it fits without adapters or wiring changes.

Every unit is bench tested at the factory for current draw, solenoid pull-in and pinion throw, because those three values decide whether a starter works in a cold engine bay as well as it does on a test bench.

Specification Summary

• Rated voltage: 12V
• Rated output: 1.4 kW
• Pinion: 11 teeth
• Type: reduction gear starter with pre-engaged solenoid
• Application: Maxima Infiniti I30 I35
• Net weight: approximately 3.5 kg
• Condition: new, direct replacement for the original unit

A 12V 1.4 kW rating is the output the motor can hold while cranking, not a peak figure. It is sized so the engine reaches starting speed on the first or second revolution, which is what makes a healthy start feel immediate.

A pre-engaged solenoid pushes the pinion into mesh before the main contact closes, which prevents the tooth damage that occurs when a motor spins up against a stationary ring gear.

Cross references are a guide, not a fitment guarantee. The same engine family was often built with more than one starter, and the pinion module or terminal bracket can differ between them, so confirm the number on the unit being replaced. This starter is listed with 16 references in total.

Where This Starter Is Used

The unit is listed for Maxima Infiniti I30 I35. Because manufacturers changed starter suppliers during the production run, the safest check is the number stamped on the starter body, not the model year alone. For the S114-801, the practical check is the number stamped on the housing.

If the number on the old unit falls outside the list above, send the engine code and a photograph of the drive end before ordering. A starter with the correct housing but the wrong pinion will grind on the first attempt and can chip the ring gear.

Why These Starters Fail

The brush plate is the second common failure point. Brushes shorten gradually, spring pressure falls, and contact becomes intermittent. Cranking speed drops a little every week until the engine refuses to start on a cold morning.

Most failures start at the solenoid contact. Each start switches the full cranking current through a copper disc, and after thousands of cycles that disc pits and burns. The result is the familiar single click with no rotation, or a delay before the motor turns. Where a S114-801 has been replaced before, check that the fitted unit still matches the reference list.

Symptoms of a Failing Starter

• Click from the solenoid with no rotation, sometimes clearing on a second attempt
• Cranking that has become slower over several weeks
• Grinding as the pinion meets the ring gear
• Starter that keeps running after the key is released
• Intermittent no-crank that appears when the engine bay is hot

Before replacing the starter, check the battery state of charge, the terminal clamps, the engine earth strap and the main cable. On vehicles of this age a corroded earth connection produces exactly the same slow-crank symptom and costs far less to correct. Owners of Maxima Infiniti I30 I35 should treat the S114-801 reference list as a starting point, not the final answer.

What to Check Before Fitting

• State of charge and age of the battery
• Corrosion on the earth strap and the engine-to-body bond
• Pinion tooth count against the ring gear
• Free movement of the new pinion before fitting
• That the signal wire connector seats fully on the solenoid

Fitting a new starter onto a worn ring gear or a marginal battery shortens its life. Check the simple items first, then fit the unit once and correctly.

Fitting the Replacement

Raise and support the vehicle where the starter is reached from below, disconnect the battery, and detach the main cable and signal wire. Note the cable positions before removal so the replacement goes back the same way.

Check the ring gear through the aperture before fitting. Install the new unit with the original bolts, reconnect the cables in the same order and tighten the main terminal without over-stressing the stud. Crank briefly and confirm the pinion releases as the engine fires. Fitting the S114-801 correctly takes less time than diagnosing the original fault.

Frequently Asked Questions

Can I test the starter on the bench?

Yes. Apply battery voltage to the main stud and the signal terminal and check that the pinion throws and the motor turns. A clamp meter reading against the rated current will show whether the unit is drawing too much.

Why does the starter work cold but fail when hot?

Heat raises solenoid resistance and reduces brush spring pressure. Both effects build up gradually and appear first on a hot restart.

Is a 12V and a 24V starter interchangeable?

No. The voltage rating must match the vehicle system; fitting the wrong unit will damage the starter and the wiring.

Does the starter need any maintenance?

No routine maintenance is required. Keeping the battery, terminals and earth connections clean is what extends starter life in practice.
