Caterpillar 600-8815 is the proportional cartridge solenoid valve: a plated coil with a two hole mounting flange, a brown plug on the coil end and a long spool with O-rings and a fine screen. It is used on Caterpillar 740C and 745C trucks. This aftermarket valve has the same ports, mounting and coil connector as the original, so it fits where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Applications & use cases
Function will not work
If a hydraulic function is dead but the pump and controls work, the solenoid valve or its coil is the usual suspect.
Drift or creep
A valve that does not seal lets cylinders creep. A new valve restores holding.
Burned coil
A coil that reads open or short on a meter needs replacing; check the connector for water first.
Fleet spares
Keep the common valves for your machines in stock to cut downtime.

Frequently asked questions
Will it replace my Caterpillar 600-8815?
Yes, it is a direct replacement for the Caterpillar 600-8815 with the same fitting.
How often should I replace the Caterpillar 600-8815?
There is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
What are the signs the solenoid valve needs replacing?
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Should I grease the connector?
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
Does the voltage matter?
Yes. Many machines have 12 V and 24 V versions of the same solenoid valve. Check the old part or the machine plate before fitting.
Is this a genuine Caterpillar 600-8815?
No. It is an aftermarket solenoid valve made to replace the Caterpillar 600-8815. It is not made by the original manufacturer; the number only shows what it replaces.
