Important Part-Number Revision Note

Royal Enfield has catalogued earlier versions 575515/A and 575515/B. Parts documentation shows that the earlier plug may be replaced or alternated by later revisions in applicable 650 Twin assemblies.

This listing is specifically for 575515/C. Match the full part number and verify current Royal Enfield supersession information before substituting another suffix.

Important Washer and Pack-Contents Note

This listing is for the magnetic plug assembly only. The M14 drain sealing washer is separately catalogued as 575630/B on current 650 Twin lubrication-system diagrams.

A sealing washer should be replaced whenever required by the workshop manual or when the existing washer is flattened, damaged, hardened or leaking. Do not assume a new washer is included unless it is physically present inside the supplied genuine package or clearly shown in the product photographs.

Technical Details

Purpose of the Magnetic Tip

The magnetic tip attracts fine ferrous particles produced through normal contact between steel engine and transmission components. These particles can then be removed from the plug during an oil change.

A light paste of very fine material may be seen during routine servicing. Large flakes, chips, sharp fragments or an unusual increase in metallic debris should be inspected by a qualified engine technician and must not be dismissed as normal wear.

Installation Note

Installation should be completed during an engine-oil service by a qualified Royal Enfield or motorcycle technician.

• Allow the engine to cool sufficiently before removing the drain plug.
• Use the correct tool to avoid rounding the hex head.
• Clean the magnetic tip and inspect the collected debris.
• Inspect the plug and sump threads for damage.
• Fit the correct sealing washer where required.
• Start the plug by hand to prevent cross-threading.
• Tighten only to the applicable workshop-manual torque specification.
• Refill with the correct grade and quantity of engine oil.
• Run the engine and inspect the drain-plug area for leakage.

Overtightening can damage the sump threads or plug. Undertightening, reusing a damaged washer or cross-threading can cause an engine-oil leak.

Buyer-Focused FAQs

Is this the engine-oil drain bolt?
Yes. It is the magnetic plug installed in the engine lubrication-system/oil-sump assembly.

What does the magnet do?
It attracts fine ferrous wear particles so they can be inspected and cleaned away during an oil change.

Does it fit the Interceptor 650 and Continental GT 650?
Yes, on applicable 648cc parallel-twin models specifying the 575515-series plug.

Does it fit the Super Meteor, Shotgun, Bear and Classic 650?
Yes. Current lubrication-system catalogues list 575515/C for these 648cc parallel-twin model families.

Is the drain washer included?
No. The current M14 washer is separately catalogued as 575630/B unless it is explicitly present in the supplied package.

Can I reuse the old washer?
Follow the workshop manual and inspect it carefully. A flattened, damaged or leaking washer should be replaced.

Is 575515/B the same as 575515/C?
They are different suffix revisions. Some parts documentation permits alternation on applicable 650 Twin assemblies, but the complete part number and supersession must still be confirmed.

Will this fit the Continental GT 535?
No confirmed compatibility. This listing is for the 648cc parallel-twin platform, not the older 535cc single-cylinder model.

Order Verification

Before ordering, verify the motorcycle model, engine family, original plug dimensions, sump application and complete part number. Correctly supplied service parts are not eligible for return due to incorrect model selection, incorrect diagnosis, cross-threading, overtightening or installation damage.
