Nitrile (NBR) O-Ring Assortment Kit, Metric, ...: 
Universal Filter Strap Wrench for Oil, Fuel a...: Caterpillar 154-3064 is the cartridge solenoid valve: a threaded valve cartridge with its coil, and a green two wire lead to a grey two pin Deutsch style plug. It is used on Caterpillar 140H and 160H motor graders. 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.

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.

Yes, it was made for the Caterpillar 12H, and 7 more listed under compatible equipment. Check the old solenoid valve is marked 154-3064 or one of the cross references, because makers change parts between serial ranges.
On the Caterpillar 12H, 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.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
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.
Measure the coil resistance with a multimeter and check for supply voltage at the plug with the circuit on. An open coil reads infinite.
No. It is an aftermarket solenoid valve made to replace the Caterpillar 154-3064. It is not made by the original manufacturer; the number only shows what it replaces.
