4935792 Oil Pump Ass'y for Cummins 6BT Komatsu PC200-6 Hyundai R210LC

4935792 Oil Pump for Komatsu PC200-6 and Hyundai R210LC

The 4935792 engine oil pump is supplied for heavy equipment engine lubrication system repair. It is commonly searched for Komatsu PC200-6, Hyundai R210LC and other equipment references using Cummins 6B, 6BT or 6BTA 5.9L diesel engine applications.

This page focuses on 4935792 as the main part number. 3926203, 3918212, C4935792 and 1011N-010-A2 can be used as checking references, but final fitment should be confirmed by the old oil pump number, engine model, gear design, mounting face, oil passage layout and machine information before ordering.

Engine Application: Cummins 6B, 6BT and 6BTA 5.9L

For this engine oil pump page, the strongest engine search direction is Cummins 6B / 6BT / 6BTA 5.9L. These engines are widely used in excavators, loaders, industrial equipment and heavy-duty diesel repair markets, so buyers may search by engine model even when the machine model is not clear.

The SEO Title should cover machine search intent such as Komatsu PC200-6 and Hyundai R210LC, while the H1 should reinforce the Cummins 6BT 5.9L engine direction. This gives the page broader search coverage without turning it into a general oil pump catalog.

If the buyer only provides a machine model, ask for the engine nameplate and old oil pump photos. If the buyer only provides an engine model, confirm the old pump number, gear side and pump body details before quotation.

Machine Reference for 20-Ton Excavator Repair

Komatsu PC200-6 and Hyundai R210LC are useful machine references for this product page because buyers often search engine oil pumps by excavator model during repair. The page can also naturally cover related 20-ton class equipment using Cummins 5.9L engine references, but those should remain application references rather than guaranteed fitment claims.

Older machines may have engine replacement, previous overhaul history or non-original engine parts. For this reason, the machine model alone should not be used as the only fitment proof.

For accurate ordering, compare the removed oil pump with the replacement unit before shipment. Photos of the old pump number, gear side, mounting face, oil passage area, pump housing and engine nameplate are useful for confirmation.

Part Number and Cross Reference Notes

4935792 is the main part number of this page. It should stay as the strongest signal in the SEO Title, H1, product description and image ALT text.

3926203 and 3918212 are common checking references for Cummins 6B / ISB / QSB oil pump applications. C4935792 is a common prefixed writing format, while 1011N-010-A2 appears in DCEC / Cummins 6BT 5.9L oil pump references. These references are useful for buyer matching, but the removed pump and engine information should still be checked before shipment.

I do not recommend putting every nearby number such as 3937404, 3941742, 3906414 or 4939587 into the top parameter area unless you have supplier confirmation. Some of these numbers appear in broader Cummins 5.9L oil pump listings, but adding too many references can dilute the 4935792 page signal and increase wrong-part inquiries.

How to Confirm the Correct 4935792 Oil Pump

Cummins 5.9L oil pumps can look similar, but small differences in gear design, body thickness, mounting face or oil passage layout may affect installation. Before ordering, compare the removed pump carefully.

• Confirm whether the old oil pump number is 4935792 or one of the listed checking references.

• Check whether the engine model is Cummins 6B, 6BT, 6BTA, ISB or QSB 5.9L.

• Compare the helical gear side, pump body shape and mounting face.

• Check oil inlet, oil outlet and internal oil passage positions.

• Confirm gasket surface, bolt hole pattern and timing gear fitment area.

• Send machine model, engine nameplate and old oil pump photos before quotation if you are not sure.

Why Gear Side and Lubrication Circuit Checking Matter

The 4935792 oil pump works inside the engine lubrication system, so gear side matching and oil passage alignment are important. A pump with a similar housing may still differ in gear profile, drive engagement or passage design.

For repair shops, the best confirmation method is to photograph both sides of the removed pump. If the pump has already been removed from the engine, photos of the timing gear area and engine nameplate can also help confirm the correct replacement direction.

This step is especially important for used excavators and rebuilt engines, because previous repair work may have changed the engine configuration or installed a different oil pump version.

Common Oil Pump Failure Symptoms

An engine oil pump may need replacement when the machine shows low oil pressure, oil pressure warning, unstable lubrication after startup, abnormal bearing noise, engine overheating, metal particles in oil or serious internal engine wear.

On 20-ton excavators and heavy equipment, low oil pressure may appear after long working hours, poor maintenance, oil sludge buildup, overheating or internal bearing wear. The oil pump should be checked together with the complete lubrication system.

These symptoms are not always caused by the oil pump itself. Blocked oil passages, dirty engine oil, worn bearings, damaged pickup tube, clogged strainer, pressure relief valve problems or incorrect engine oil viscosity can create similar problems.

Troubleshooting Before Replacement

Before ordering a 4935792 replacement oil pump, check the lubrication system and the real reason for low oil pressure. This helps avoid replacing the pump when the root cause is oil contamination, bearing wear or blockage.

• Check engine oil level, oil grade and oil contamination.

• Inspect the oil filter, oil strainer and pickup tube condition.

• Check whether sludge or metal particles are present in the oil pan.

• Inspect crankshaft bearings, camshaft bearings and related lubrication surfaces.

• Confirm whether the pressure relief valve is stuck, worn or contaminated.

• Clean the oil circuit if the old pump failed due to contamination, sludge or engine wear.

Installation and Maintenance Notes

Before installation, clean the timing gear area, mounting surface and oil passages. Compare the replacement pump with the removed unit, including gear position, pump body shape, bolt holes and gasket surface.

Use a proper gasket or sealing method according to the engine repair requirement. After installation, check oil pressure during startup and confirm that oil circulates normally before putting the engine under load.

For longer service life, use clean engine oil, replace filters on time and avoid running the engine with low oil pressure. If the previous failure was caused by sludge, bearing wear or contamination, those causes should be corrected during repair.
