Hero Genuine Exhaust Valve Rocker Arm for Xpulse 200 4V, Xpulse 200T 4V, Xtreme 160R 4V & Xtreme 200S OBD-II | 14440ABW800S

Hero Genuine Exhaust Valve Rocker Arm – 14440ABW800S

Replace a worn, damaged, scored or unserviceable exhaust-side valve rocker with the Hero Genuine Arm Comp., Exhaust Valve Rocker, part number 14440ABW800S. This precision valvetrain component is used in compatible Hero Xpulse 200 4V, Xpulse 200T 4V, Xtreme 160R 4V, Xtreme 200S and related four-valve engine applications.

The exhaust rocker arm transfers camshaft movement to the exhaust-valve mechanism so the exhaust valve opens and closes at the required point in the engine cycle. Correct rocker-arm geometry, movement, shaft fit and valve-clearance adjustment are important for stable valve operation, compression, engine breathing and long-term valvetrain reliability.

A worn or damaged exhaust rocker arm can contribute to excessive tappet noise, incorrect valve clearance, unstable valve movement, reduced engine performance, abnormal wear or difficulty maintaining the specified clearance. The complete cylinder-head valvetrain must be inspected because similar symptoms can also come from the camshaft, rocker shaft, valve, valve spring, adjuster, timing chain or lubrication system.

This is the exhaust-side rocker arm assembly only. It is not the intake rocker arm, rocker-arm shaft, camshaft, exhaust valve, valve spring, cylinder head or complete valve-train kit.

Fitment Note / Return Prevention Note

Before ordering, match the complete Hero part number 14440ABW800S or catalogue number 14440-ABW-800 with the motorcycle’s chassis/VIN-based cylinder-head and camshaft catalogue.

Confirm all of the following:

• Exact motorcycle model, variant and production generation
• Four-valve engine configuration
• Exhaust-side rocker-arm position
• Existing rocker-arm shape and shaft bore
• Camshaft contact area and rocker movement
• Rocker-shaft part number and condition
• Valve-clearance adjuster arrangement
• Part number shown in the camshaft/valve assembly diagram
• Part number printed on the original package, invoice or component reference

Do not confuse the exhaust and intake rocker arms:

• 14440ABW800S / 14440-ABW-800 — exhaust valve rocker arm
• 14430ABW800S / 14430-ABW-800 — intake valve rocker arm, sold separately
• 14451ABW800S / 14451-ABW-800 — rocker-arm shaft, sold separately

Hero publishes no detailed retail kit bill of materials for this rocker-arm SKU. The product is therefore supplied as the manufacturer-packed rocker-arm assembly under 14440ABW800S. No additional loose adjuster, nut, shaft, washer or valve-train hardware should be assumed unless physically present inside the sealed pack.

Excessive tappet or cylinder-head noise can also be caused by:

• Incorrect valve clearance
• Loose or damaged valve-clearance adjuster
• Worn camshaft lobe
• Worn or damaged rocker-arm shaft
• Low engine-oil level or incorrect oil
• Restricted cylinder-head lubrication
• Timing-chain or tensioner wear
• Valve, guide or spring damage
• Incorrect engine assembly

Replacing the rocker arm alone will not repair an unrelated camshaft, lubrication, timing-chain or valve fault.

Engine-component return protection: Confirm the exact part number and valve side before installation. A rocker arm showing shaft marks, valve or cam contact, adjustment marks, filing, polishing, oil contamination, heat damage or use cannot be treated as an unused return.

Technical Details

Installation Note

Cylinder-head and valvetrain work should be performed by a trained motorcycle engine technician. Incorrect rocker-arm installation or valve-clearance adjustment can cause noise, poor performance, valve damage or serious engine failure.

Before fitting:

• Compare the old and new part numbers
• Confirm that the part is for the exhaust-valve side
• Inspect the camshaft lobe for scoring, pitting or abnormal wear
• Inspect the rocker-arm shaft and shaft bore
• Inspect the exhaust-valve stem contact area
• Check the valve-clearance adjuster and lock nut
• Verify cylinder-head oil passages and lubrication
• Inspect the timing chain, guides and tensioner
• Check the valve spring and valve movement

During installation:

• Lubricate contact surfaces with the specified clean engine oil or assembly lubricant
• Install the rocker arm in the correct exhaust-side position and direction
• Do not force the rocker arm onto a damaged or incorrect shaft
• Use the correct rocker shaft and retaining arrangement
• Set valve clearance according to the exact model’s service specification
• Tighten the adjuster lock nut and cylinder-head components to prescribed torque
• Rotate the engine manually through the required cycle before starting
• Confirm free movement and correct timing

After assembly, start the engine only after confirming oil level, timing and valve clearance. Listen for abnormal cylinder-head noise and check for oil leakage. Recheck valve clearance after the service procedure’s specified inspection or running period where required.
