Two numbers appear on the box, and only one of them is a Caterpillar part number. Getting that straight saves a workshop from quoting the wrong reference into their own system and losing traceability on the part.<\/p>\n
265-4925 is catalogued as a Gear Motor<\/strong>, and the parts book item name is more specific still: MOTOR GP-GEAR -HYDRAULIC FAN, listed under the hydraulic system section of the 938H and recorded as part of the radiator and fan group. So the function is not an inference from a supplier title. Caterpillar’s own literature says this gear motor drives the cooling fan.<\/p>\n The unit in our photographs carries a maker plate reading PT. NO. 7029210020, serial 0001, dated 2025.09.28, with the housing cast 8002-902-OEM. That is the producing manufacturer’s own part reference, the number they use internally and the number that appears on Chinese marketplaces alongside the Cat number. It is useful for tracing which factory built a unit and for ordering a seal kit from that maker. It is not a Caterpillar cross-reference, and it should not be entered into your system as though it were equivalent to 265-4925.<\/p>\n We print both on the packing list, labelled, so your stores team can book the part against the Cat number and keep the maker code for warranty traceability.<\/p>\n CAT 938H wheel loader and IT38H integrated toolcarrier, parts literature covering machine prefix MJC from 00001 with the Cat C6.6 engine. The 938H is a smaller machine than the 980H, and the difference matters here: the 938H uses a engrenagem<\/strong> fan motor, while the 980H uses a pist\u00f5es<\/strong> fan motor, 255-6805. Same job, different construction, and no interchangeability between them.<\/p>\n A gear motor is simple: two meshing gears, a housing, a seal. It has no regulator, no valve plate, no slipper interface. When it under-performs, the cause is almost always wear from contamination or heat, or a shaft seal that has been pushed out by case drain back-pressure. That means the diagnosis is short and the repair is usually not just the motor.<\/p>\n Nosso guia de diagn\u00f3stico de motor de ventoinha hidr\u00e1ulica<\/a> covers the tests in detail, and o artigo sobre v\u00e1lvula de reten\u00e7\u00e3o<\/a> covers the case where a loader still runs hot after the fan parts have been replaced.<\/p>\n Match shaft form, flange bolt pattern and port thread sizes against the removed motor. Prime before cranking. Fit a new return filter element and clear the suction strainer, holding cleanliness around ISO 4406 18\/16\/13 as the working target for piston components sharing the circuit. Confirm rotation direction with the fan restrained, then prove full fan speed under thermal load.<\/p>\n Minimum order one piece. New aftermarket units carry a three to six month warranty as stated on your proforma invoice. Bench tested, photographed against your order before the wooden case closes, delivery 5 to 8 working days from payment subject to stock.
