Confirmed Compatibility

Registration year alone is not sufficient where an engine cover has previously been replaced. Compare the original cap, mounting pattern and sealing method before opening the package.

Do Not Order For

• Royal Enfield Himalayan 450 with the Sherpa 450 engine
• Royal Enfield Guerrilla 450
• Royal Enfield Scram 440 unless independently confirmed by the old part number
• Classic 350 Reborn, Meteor 350, Hunter 350 or new Bullet 350 J-Series models

Sealing Arrangement: Check Before Ordering

Royal Enfield 411 engines use more than one oil-filter-cap sealing arrangement:

• Earlier motorcycles: commonly use oil-filter cap O-ring 574301/B.
• Later motorcycles: may use flat oil-filter cap gasket 574672/B.

Inspect the removed cap and engine cover before selecting the seal. Do not assume that the O-ring, gasket or any other sealing part is supplied with cap 574300.

What the Oil Filter Cap Does

The cap closes the external cartridge oil-filter housing in the right-hand engine cover. When installed with the correct filter, spring, seal and fasteners, it helps retain the filter assembly and prevent engine oil from leaking at the housing.

A new cap will not correct a leak caused by a damaged engine-cover sealing surface, incorrect gasket, reused hardened O-ring, loose or stretched fastener, incorrect assembly or damaged threads.

What You Will Receive

1 × Genuine Royal Enfield oil filter cap / cover – SKU 574300

The oil filter, spring, O-ring, flat gasket, mounting fasteners, engine oil, right-hand clutch cover and installation labour are not included unless physically shown as part of the sealed manufacturer package.

When Should the Cap Be Replaced?

• The cap is cracked, chipped or physically broken
• The sealing face is scratched, distorted or corroded
• The cap has been bent through overtightening or impact
• The fastener seats or mounting points are damaged
• Oil leakage remains after confirming the correct new seal and proper installation
• The original cap is missing during an engine or oil-filter repair

Diagnostic Note

If oil is leaking around the filter housing, clean the area and identify the exact source before replacing the cap. Inspect the O-ring or gasket, filter spring, cap sealing face, engine-cover surface, fasteners and threads. Oil from above the housing can travel downward and appear to be a cap leak.

Installation Note

• Work only with the motorcycle secure and the engine cool.
• Perform the procedure as part of the applicable oil-filter service.
• Support the cap while loosening it because the filter spring sits behind the assembly.
• Record the filter, spring and seal orientation before removal.
• Clean the cap and engine-cover sealing surfaces without gouging them.
• Fit the correct new O-ring or gasket for the motorcycle's existing arrangement.
• Do not use excess sealant or stack seals unless the applicable service information specifically instructs it.
• Tighten fasteners evenly to the factory specification for the motorcycle; no universal torque should be assumed.
• Refill or correct the engine-oil level, start the engine and inspect carefully for leaks.
• Professional installation is recommended if the threads, engine cover or sealing surface are damaged.

Important Return-Prevention Check

Before opening or installing the part, confirm all of the following:

• The required item is an oil filter cap, not an oil filler plug
• The required base part number is 574300 or current revision 574300/E
• The motorcycle is a Himalayan 411 or Scram 411 with the 411-platform engine
• The old and new mounting patterns and sealing faces match
• The correct separate O-ring or flat gasket has been identified
• The leak has not been caused by the engine-cover surface, threads or incorrect installation

We do not offer exchanges. A correctly supplied item is not returnable or refundable after delivery, opening, installation, testing or use. Wrong model selection, confusing the filter cap with the filler plug, choosing the wrong seal or incorrect diagnosis does not make the supplied part incorrect. Record a complete unboxing video and report a wrong, missing or transit-damaged item within 24 hours with the required proof.

Frequently Asked Questions

What is Royal Enfield part 574300?

574300 is the oil filter housing cap fitted to the right-hand engine cover on the applicable Himalayan 411 and Scram 411.

Why do some catalogues show 574300/E?

574300/E is the current revision shown in later Royal Enfield parts references. This listing uses the base SKU 574300 while recording the revision for comparison.

Is this the engine-oil filler cap?

No. The threaded oil filler plug is a different part, commonly referenced as 574304/C.

Does the oil filter come with the cap?

No. This listing guarantees one oil filter cap only. The filter element is ordered separately.

Is the O-ring included?

No separate seal is guaranteed. Earlier motorcycles commonly use O-ring 574301/B, while later motorcycles may use flat gasket 574672/B.

Does it fit both BS4 and BS6 Himalayan 411?

Yes, the cap is catalogued in Euro 4/BS4 and Euro 5/BS6 Himalayan 411 right-hand-cover assemblies. Always compare the sealing arrangement before installation.

Will it fit the Scram 411?

Yes, it is used with the same 411-platform mechanical oil-filter housing. Confirm the old cap and seal arrangement before ordering.

Will it fit the Himalayan 450?

No. The Himalayan 450 uses the different Sherpa 450 engine and is not included in this fitment.

Can a new cap stop an oil leak?

It can correct a leak caused by a damaged or distorted cap, but it will not repair a worn seal, damaged engine-cover face, stripped thread or incorrect assembly.

Should the seal be replaced during installation?

Yes. Reusing a hardened, flattened or damaged O-ring or gasket can cause a leak even with a new cap.

Are the mounting bolts included?

No mounting fasteners are guaranteed with this listing. Inspect and order the correct fasteners separately if required.
