3537424 Main Bearing 0.025 mm for Caterpillar

3537424 is a main engine bearing with a 0.025 mm undersize specification for Caterpillar equipment using 3054 and 3056 engine series. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The part is identified as a main bearing for the engine crankshaft assembly. The available application data specifies the Caterpillar 3054 and 3056 engine series; individual machine model numbers are not provided in the source data.

The bearing is supplied under the 3537424 part number and the equivalent hyphenated designation 353-7424. The 0.025 mm value is part of the bearing specification and should be matched with the engine service measurements and the required crankshaft journal size during parts selection.

Fitment

• Caterpillar equipment fitted with 3054 engines
• Caterpillar equipment fitted with 3056 engines
• Engine bearing application: main bearing position

The listed fitment refers to the engine series rather than to a complete machine model list. The source data does not identify specific Caterpillar tractor, excavator, loader, or other machine model numbers. Compatibility should therefore be checked by the engine series and the required bearing size.

Cross-reference numbers

3537424 and 353-7424 are two number formats identifying the same bearing reference in the available product data. The source description identifies this reference as the Caterpillar equipment part number. No additional supplier cross-reference numbers are specified.
