Workshop guide
Finding the correct hydraulic hose for Caterpillar 320CUL
Start with the machine and route
For Caterpillar 320CUL, identify the exact model and hydraulic system on the machine first. A part number or diagram pipe number is the fastest way to narrow a replacement hose; if neither is visible, compare the installation route and the existing hose.
Read the dimensions before cutting
Check whether a listed dimension is finished assembly length, hose-only length, or cut length. These are not interchangeable. Confirm hose specification and pressure rating, then compare both ends separately: thread, sealing seat, size, angle, and orientation.

Use the drawing as a location check
Where an installation drawing or manual figure is available, match its callout to the part number and physical route. A hydraulic circuit diagram explains connections but does not show the exact routing of a hose on the machine. Take the old hose or clear end-fitting photographs to the workshop if any dimension is missing.

Common Repair Questions
Questions appear only when a published record or linked PDF page provides the answer.
What is the hose length range for Caterpillar 320CUL?
Based on published records with valid lengths, the range is 770 mm. Open the individual record to verify its installation position and both end fittings before fabrication.
Which hose specifications are common for Caterpillar 320CUL?
The most frequent raw specifications in the current published records are: 13I (1 records). Verify the specification together with length, pressure, and fitting details.
How can I identify the left and right hose fittings for Caterpillar 320CUL?
Each record keeps the left and right fitting descriptions separate. Current examples: 5I-4396: left 13/16 0°（手写接头规格）; right 13/16 90°（手写接头规格）. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

I am checking hydraulic hose repair information for "Caterpillar 320CUL Hose Length & Fitting 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/caterpillar/320cul--33323043554c/ 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.
