1945603 is a hydraulic cylinder seal kit for Caterpillar equipment. The part is used with Caterpillar 426C, 436C, 438C and 3054 applications listed for backhoe loaders and engine-machine assemblies.

This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts). The kit is supplied under the part designation KIT-SEAL and is identified by the Caterpillar-style number 194-5603 as well as the numeric designation 1945603.

The product belongs to the Hydraulic Cylinder Seals Kits category. Its application is associated with hydraulic cylinder and rod sealing, while the available product data does not specify the individual seals included in the kit, their material, or the cylinder position on the machine.

Fitment

The available fitment information identifies the following Caterpillar equipment models and machine applications:

• Caterpillar 426C backhoe loader
• Caterpillar 436C backhoe loader
• Caterpillar 438C backhoe loader
• Caterpillar 3054 engine-machine application

The model references above are taken from the supplied application data. The description does not provide additional serial-number ranges, production years, cylinder identification details, or machine configuration codes. Compatibility should therefore be checked against the equipment model and the part number before installation.

For the 426C, 436C and 438C references, the part is listed in connection with Caterpillar backhoe loader equipment. The 3054 reference is listed as an engine-machine application. No other equipment brands or additional Caterpillar models are specified in the available data.

Cross-reference numbers

194-5603 and 1945603 identify the same seal-kit application in the supplied product information. The number 1945603 is the SKU for this product. No additional supplier numbers are specified.

Specifications

The dimensions provided are 11.8 cm in length, 5 cm in width and 12 cm in depth. The available data does not identify whether these measurements refer to the packed kit or the component itself, and it does not provide a cylinder bore diameter, rod diameter, seal profile, material specification, thread information, or a list of kit contents.

When identifying the required part, use the complete number 1945603 or the hyphenated designation 194-5603 together with the Caterpillar equipment model. The model and part-number check is required because the available application data is limited to the listed models and does not include serial-number or configuration coverage.
