BAJAJ BOXER AT DF04 MAGNET COIL PLATE ASSEMBLY (3LT 4 HOLE) 4+3 PIN

Bajaj Boxer At Df04 Magnet Coil Plate Assembly 3lt 4 Hole 43 Pin

The Bajaj Boxer At Df04 Magnet Coil Plate Assembly 3lt 4 Hole 43 Pin is a precision-engineered motorcycle magneto generator stator plate designed specifically for BAJAJ BOXER AT DF04 MAGNET (3LT 4 HOLE). Serving as the electrical power generation core of your motorcycle charging and ignition infrastructure, this heavy-duty assembly supplies alternating electrical current (AC) to keep your 12V battery fully charged while delivering exact pulse signals to trigger synchronized spark plug firing. Explore our comprehensive selection of high-grade motorcycle electrical components in the Coil Plate Assembly collection.

• Note: Flywheel rotor, mounting case screws, and engine case paper gasket are not included and should be inspected/reused from your motorcycle.

Installation & Electrical Diagnostic Tips

To ensure maximum charging efficiency and prevent premature electrical failures, follow these four mechanic-approved workshop installation procedures:

1. Rotor Taper Cleanliness & Flywheel Pulling: Always use a dedicated model-specific motorcycle flywheel puller tool to remove the rotor. Never hammer or pry the flywheel edges, as this cracks internal magnets. Clean the crankshaft taper and keyway thoroughly with solvent before installing the new stator plate to ensure solid seating.
2. Pickup Air Gap Calibration: After bolting the coil plate backing into the crankcase, measure the air gap clearance between the pickup coil metal tip and the raised flywheel reluctor lobe using a brass or non-magnetic feeler gauge. The optimal gap is between 0.50mm and 0.70mm. A gap that is too wide leads to misfiring, while a gap that is too narrow risks rotor contact.
3. Multimeter Electrical Diagnostic: Before reinstalling the engine cover, test winding resistance across the charging leads using a digital multimeter set to ohms (Ω). Confirm there is zero continuity between any charging phase wire and the engine ground (unless specified by single-wire grounded circuits). Test the pickup coil resistance to confirm it matches the factory service manual.
4. Crankcase Grommet Sealing & Harness Routing: Seat the molded rubber wire grommet firmly into the engine case notch. Apply a thin film of high-temperature oil-resistant RTV silicone sealant around the perimeter of the grommet to eliminate oil leaks. Route wires away from the flywheel rim and sprocket chain using OEM retaining clips.

Frequently Asked Questions

What are the symptoms of a failing motorcycle coil plate assembly?

Common symptoms of a defective stator coil plate include frequent battery discharge while riding, weak or intermittent spark at the spark plug, flickering headlamps, and complete charging failure where the motorcycle dies as soon as the battery drains.

Is this coil plate assembly wound with pure copper wire?

Yes. The Bajaj Boxer At Df04 Magnet Coil Plate Assembly 3lt 4 Hole 43 Pin is built exclusively with 100% pure electrolytic grade copper wire coated with high-grade thermal enamel. Pure copper winding offers superior electrical conductivity, minimal resistance heat loss, and longer operating life compared to cheaper copper-clad aluminum alternatives.

Can I install a 12-pole stator coil plate on an 8-pole motorcycle?

No. You must strictly match the stator pole count of your original factory setup. Installing a mismatched pole count alters the AC generation frequency, prevents proper synchronization with the flywheel rotor magnets, and can damage your regulator rectifier or CDI unit.

What is included in the package?

The package contains the complete factory-tested Bajaj Boxer At Df04 Magnet Coil Plate Assembly 3lt 4 Hole 43 Pin with integrated pulse pickup sensor, heat-resistant wiring lead, pass-through rubber grommet, and pre-crimped 4+3-Pin coupler.

Do you offer free shipping?

Yes. Free shipping across India.
