6204-61-1104 Water Pump for Komatsu PC60-5 PC60-7 PC75UU-2 PC120-5

6204-61-1104 Water Pump for Komatsu S4D95 4D95L

The 6204-61-1104 water pump is used for Komatsu S4D95 4D95L engine cooling repair. It is commonly searched for compact and mid-size Komatsu equipment such as PC60-3 PC60-5 PC60-7 PC75UU-2 PC80-3 PC120-5 PW60-3 references.

This product page should focus only on the 6204-61-1104 water pump group. The old page currently contains 4D94E, 4D94LE information, but those belong to a different Komatsu forklift water pump page and should be removed from this product.

Product Details for 6204-61-1104 Water Pump

Compact Komatsu Equipment Repair Coverage

Unlike the larger PC200 and PC220 water pump pages, this part is better positioned for compact Komatsu machines and smaller 4-cylinder engine applications. Buyers may search it from a PC60 excavator repair, a PC75UU compact machine, a PC80-3 jobsite unit, or a PW60 wheeled excavator cooling fault.

These machines are often old enough to have mixed maintenance records, imported used parts, or previous engine repairs. For that reason, the removed pump is more reliable than the machine model alone.

If the buyer only has a photo of the old pump, ask for the rear side, gasket face, shaft side and outlet direction. These views are usually more useful than a general machine photo.

Parts Counter Verification Notes

Field Use Cases for 6204-61-1104

For PC60-5 and PC60-7 excavators, this pump is commonly checked when the machine overheats during trenching, backfilling, grading, light demolition or long travel operation.

For PC75UU-2 and compact swing machines, the cooling system may run under tight engine-bay space, dust exposure and frequent stop-start cycles. A weak pump, blocked radiator or worn fan belt can show similar symptoms.

For PW60-3 or other wheeled references, check road-travel heat load, belt condition and coolant circulation before assuming the pump alone caused the temperature rise.

For PC120-5, confirm whether the actual engine and pump housing match the 4D95L reference before ordering, because used machines may have previous engine service history.

Remove the Mixed Pump Directory Content

The old Product Description includes a long list of unrelated pump numbers. Many of them are hydraulic pump or gear pump references, not Komatsu S4D95 water pump references.

Numbers such as 705-51-30290, 705-52-20240, 07400-40500 and 07448-66103 should be removed from this page. They belong to different pump categories and should not support this product's SEO signal.

This page should read like a focused compact Komatsu water pump product page, not a general pump list.

Installation Checks for Compact S4D95 Machines

Before installation, clean the engine-side mounting face and compare the gasket profile with the removed pump. Old gasket residue or corrosion can cause coolant leakage even when the pump is correct.

Check the fan belt, pulley alignment, radiator surface, thermostat and coolant hose condition while replacing the pump. Compact machines often show overheating from several small issues at the same time.

After installation, refill coolant, remove trapped air and check for leakage around the gasket edge, drain area, hose joints and pulley side.

During the first work cycle, monitor temperature under load, not only at idle. Some cooling faults appear only after travel, trenching or continuous hydraulic operation.

Can this pump fit Komatsu PC60-5 and PC60-7?

PC60-5 and PC60-7 are common application references for this water pump group. Final fitment should be verified by old pump number, engine model and machine configuration.

What should be checked before shipment?

Check the old pump number, rear housing shape, gasket face, bolt pattern, pulley side, outlet direction, engine model and machine model. Clear photos of the removed pump are recommended.
