Based on current published data

Common Repair Questions

Questions appear only when a published record or linked PDF page provides the answer.

How many hoses are currently listed for Caterpillar CAT®245D Attachments?

There are 10 published records. 10 include a length, both end fittings, and a part number or diagram pipe number.

What is the hose length range for Caterpillar CAT®245D Attachments?

Based on published records with valid lengths, the range is 279–2,210 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Caterpillar CAT®245D Attachments?

The most frequent raw specifications in the current published records are: DN13;4SP-8;28Mpa (4 records), DN25;4SP-16;35Mpa (2 records), DN10;1SN-6;15.7Mpa (1 records), DN10;4SP-6;28Mpa (1 records), DN25;4SP-16;28Mpa (1 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Caterpillar CAT®245D Attachments?

Each record keeps the left and right fitting descriptions separate. Current examples: 7V-1038: left 美制内螺纹37°锥; right 美制内螺纹37°锥; 2V-0512: left 美制内螺纹37°锥; right 美制内螺纹37°锥; 3V-9375: left Heavy-series flange; right Heavy-series flange. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Caterpillar CAT®245D Attachments hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 39 (7V-1038), Pipe No. 21 (2V-0512), Pipe No. 17 (3V-9375), Pipe No. 18 (2V-1061). Open a record to compare its installation position with the linked manual page.
