The 1-13100-244-1 engine oil pump is supplied for Isuzu 6BD1 and 6BD1T diesel engine lubrication system repair. It is commonly searched as 1-13100-244-1, 1131002441, engine oil pump, lubrication oil pump or oil pump assembly for Hitachi EX200 series excavator engine applications.

This page focuses on 1-13100-244-1 as the main part number. 1131002441 is the compact no-hyphen format, while 8-94366-241-0 and 8943662410 may appear as cross reference numbers in aftermarket listings. Final fitment should be confirmed by the old oil pump number, engine model, pump body shape, gear design, mounting face and machine information before ordering.

Engine Application: Isuzu 6BD1 / 6BD1T

For engine-part SEO clarity, this product should be strongly connected with the Isuzu 6BD1 and 6BD1T engine. Buyers may search by engine model when the machine model is unclear, when the engine has been rebuilt, or when the old oil pump has already been removed from the machine.

The 6BD1 / 6BD1T engine direction is more stable than a long list of machine models. For this reason, the H1 should focus on 1-13100-244-1 and Isuzu 6BD1 / 6BD1T engine, while the SEO Title can cover Hitachi EX200 model search intent.

If the customer only provides an engine model, ask for the engine nameplate and old oil pump photos. If the customer only provides a machine model, confirm whether the machine is still using the original Isuzu 6BD1 or 6BD1T engine before quotation.

Machine Model Reference for Hitachi EX200

Common application references for this oil pump include Hitachi EX200-1, EX200-2 and EX200-3 machines using Isuzu 6BD1 or 6BD1T engine references. These model names should be treated as application references, not as the only fitment proof.

Older excavators may have engine replacement, previous overhaul history or non-original oil pump changes. The old pump and engine information are more reliable than machine model alone.

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

Part Number and Reference Notes

How to Confirm the Correct Engine Oil Pump

Engine oil pumps can look similar from the outside, but small differences in gear design, mounting face or oil passage layout may cause installation problems. Before ordering, check the removed oil pump carefully.

• Confirm whether the old oil pump number is 1-13100-244-1 or 1131002441.

• Check whether the engine model is Isuzu 6BD1 or 6BD1T.

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

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

• Confirm gasket surface, bolt hole pattern and drive gear arrangement.

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

Common Oil Pump Failure Symptoms

An engine oil pump may need replacement when the engine shows low oil pressure, oil pressure warning, abnormal bearing noise, poor lubrication, engine overheating, metal particles in engine oil or serious wear after long-term operation.

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

Before replacing the oil pump, inspect the lubrication system and confirm the root cause of low oil pressure. Installing a new pump without cleaning the oil circuit may lead to repeated engine damage.

Troubleshooting Before Replacement

Before ordering a 1-13100-244-1 replacement oil pump, check the related engine lubrication parts. This helps repair shops and equipment owners avoid unnecessary replacement or repeated failure after installation.

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

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

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

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

• Confirm whether metal debris or sludge is present in the oil pan.

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

Installation and Maintenance Notes

Before installation, clean the mounting surface and oil passages. Compare the replacement oil 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.
