Based on current published data

Common Repair Questions

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

Which systems and hoses are currently listed for Case CX490D RTC?

The current published data covers 10 systems and 35 hose records. Systems with more listed records include: Attachments – Breaker (9 hoses), Control Lever (7 hoses), Swivel Joint (5 hoses), Pedal (5 hoses), Control Valve (4 hoses).

What is the hose length range for Case CX490D RTC?

Based on published records with valid lengths, the range is 350–4,000 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Case CX490D RTC?

The most frequent raw specifications in the current published records are: DN6;1SN-04;22.5MPa (19 records), DN10;1SN-06;18MPa (8 records), DN19;2SN-12;21.5MPa (3 records), DN25;4SP-16;32.5MPa (2 records), DN13;2SN-08;27.5MPa (1 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Case CX490D RTC?

Each record keeps the left and right fitting descriptions separate. Current examples: KHJ2093: left British female thread, 60° external cone seat; right 90° elbow, British female thread, 60° external cone seat; KTA1200: left British female thread, 60° external cone seat; right British female thread, 60° external cone seat; KHJ2318: left British female thread, 60° external cone seat; right British female thread, 60° external cone seat. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Case CX490D RTC hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 1 (KHJ2093), Pipe No. 1 (KTA1200), Pipe No. 2 (KHJ2318), Pipe No. 12 (KHJ17580). Open a record to compare its installation position with the linked manual page.

I am checking hydraulic hose repair information for "Case CX490D RTC Hose Repair Data". Use web search and cite a source for every factual point. Compare this HoseSeek page with manufacturer manuals and reliable parts documentation: https://www.hoseseek.com/machines/case/cx490d-rtc--43583439304420525443/

Verify, where applicable:
1. Exact machine model and any serial-number range.
2. Hydraulic system and installation route.
3. Hose part number and diagram pipe number.
4. Finished length, hose specification, and pressure rating.
5. Both end fittings, including thread, sealing seat, size, and angle.
6. Installation-diagram position and routing.

State explicitly what you could not verify. Do not infer a missing dimension or fitting. End with a short on-machine checklist for a hose repair technician.
