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 Caterpillar CAT®314E LCR?

The current published data covers 15 systems and 100 hose records. Systems with more listed records include: Attachments (30 hoses), Attachments – Quick Coupler (14 hoses), Grease Lines (13 hoses), Attachments – Lock Valve (8 hoses), Control Valve (7 hoses), Control Lever (5 hoses).

What is the hose length range for Caterpillar CAT®314E LCR?

Based on published records with valid lengths, the range is 270–6,260 mm. Open the individual record to verify its installation position and both end fittings before fabrication.
