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®312D Solenoid Valve?

There are 3 published records. 3 include a length, both end fittings, and a part number or diagram pipe number.

What is the hose length range for Caterpillar CAT®312D Solenoid Valve?

Based on published records with valid lengths, the range is 850–1,400 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Caterpillar CAT®312D Solenoid Valve?

The most frequent raw specifications in the current published records are: DN10;1SN-6;10.4Mpa (2 records), DN10;-6;10.3Mpa (1 records). Verify the specification together with length, pressure, and fitting details.
