Ensure your engine’s lubrication system is operating reliably with the genuine Royal Enfield 1570103/D Oil Pump Assembly (with PRV). This OEM pump is the factory-specified unit that delivers oil flow and pressure control through its built-in Pressure Relief Valve (PRV), ensuring proper lubrication under all operating conditions.

This pump is confirmed in Royal Enfield’s parts catalog as the exact same unit mounted originally in their motorcycles. 1570103/D is used in Meteor 350, All New Classic 350 / Classic Reborn, Hunter 350, and Bullet 350 models. If your pump has worn out, shows signs of low oil pressure, or you suspect internal damage, replacing it with this genuine unit restores factory oil delivery, improves reliability, and helps prevent engine damage.

⚠️ Important: This is an engine part. Always verify your current pump’s part number and housing port alignment before ordering, as slight variations can exist across model years / variants.

FAQs:

1. What does “with PRV” mean?

   → ❓ No ONLY J SERIES BIKES LIKE HUNTER METEOR REBORN

3. Is this OEM or aftermarket?
   → ✅ OEM — a genuine Royal Enfield spare listed in the official parts catalog. 

4. What are signs a pump needs replacement?
   → Low oil pressure warning, engine noise under load, oil starvation in critical parts, inconsistent oil pressure gauge reading (if applicable).

5. Can I install it myself?
