387-9886 12V Stop Solenoid Valve for CAT Skid Steer Mini Excavator Governor Control Solenoid

Product Overview

Part number 387-9886, also written as 3879886, is a vital 12V fuel stop and governor control solenoid built for Caterpillar heavy equipment. This solenoid receives power-off signals from the ignition switch or safety system, cutting off fuel supply rapidly to shut down the engine safely. Many CAT compact machines use diesel engines co-developed or manufactured by Kubota, so this CAT solenoid shares identical construction with matching Kubota fuel solenoids. It directly cross-references Kubota part numbers 1G772-60012 and 1G772-60010 for V3300, V3600, V3800 large displacement engines. It fits a wide lineup of CAT skid steer loaders, track loaders, small wheel loaders, mini excavators and asphalt pavers.

FAQs

Q: What CAT machines does 387-9886 stop solenoid fit?

A: It fits CAT skid steer & track loaders: 236D,236D3,242D,242D3,246D,246D3,262D,262D3,257D,257D3,259D,259D3,277D,279D,279D3,287D,289D,289D3; small wheel loaders 906H2,906K,906M,907H2,907K,907M,908H2,908K,908M; mini excavators 306E,307E,307E2,308E,308E2,308.5,310 series; asphalt pavers AP300,AP300F,AP355,AP355F.

Q: What cross part numbers work as replacement for 387-9886?

A: It can be replaced with Kubota 1G772-60012 and 1G772-60010, designed for Kubota V3300, V3600, V3800 engines installed inside CAT equipment.

Q: What are the failure symptoms of this 387-9886 governor control solenoid?

A: When the pull coil or hold coil burns out, you will see two typical issues. The engine starts but stalls immediately once you release the key back to ON position. Or the machine cannot start at all because the plunger sticks closed and blocks fuel flow.

Q: How does this CAT 387-9886 fuel shutoff solenoid work?

A: It receives the power-off signal from key switch or safety system. Once triggered, it closes the fuel path to shut down the engine quickly and securely.

Q: Why is this CAT solenoid compatible with Kubota part numbers?

A: Some CAT compact machines adopt Kubota-made diesel engines, so this CAT branded stop solenoid is the same component as the corresponding Kubota fuel shutoff solenoid.
