XCMG ZL30G Parts Catalog

If you’re trying to track down a part number for a ZL30G wheel loader and you’re stuck with a generic parts book that lists the wrong seal or a different brake piston, you already know the frustration. That’s why I keep a factory XCMG ZL30G Parts Catalog on the bench. This is the OEM document—106 pages of exploded diagrams and part numbers straight from the factory in Xuzhou. No translation errors, no missing sections. You get the exact breakdown of the Engine system, Fuel tank, Brake assemblies, Transmission internals, and every Torque converter component with the correct Valve and seal specs. If you’ve ever bolted up a mismatched part because some aftermarket catalog used a superseded number, you know exactly what I’m talking about.

Engine System and Fuel Tank Assembly – Chapter 1 Breakdown

Section Z3G.1 covers the diesel engine system – every mounting bracket, gasket, injector line, and pulley. Z3G.1.2 diagrams the fuel tank assembly with all fittings and caps. For basic engine theory, you can check Internal Combustion Engine, but when you need the actual part number for that fuel return line, this catalog delivers. No generic cross-references.

Brake System and Transmission – Factory Parts Exploded Views

Chapter 6 covers the disk brake assembly (Z3.2.00) and the parking brake (Z3G.6.4.1). The transmission section (Z3G.6) breaks down every shaft, gear, and control valve assembly. If you rebuild a transmission without the right bearing numbers, you’re asking for a tear-down. This catalog lists them all, including the Torque Converter (Z3.3.00) and the Reducing Valve Assembly (Z3.3.00).

Torque Converter and Valve Assemblies – Critical Specs

The torque converter section (Z3.3.00) shows every vane, stator, and seal. The valve assemblies—single-stabilizer valve (Z3.9.00), control valve (Z3.10.00), and transmission control valve—are diagrammed with internal spring and plunger part numbers. When a valve sticks, you need the correct O-ring. This catalog gives you that.

Does This Catalog Cover the Electrical System?

Page 94 shows the electrical system (Z3G.14): wiring harnesses, sensors, switches, and the start motor. Not a wiring diagram for diagnostics—this is a parts list for ordering the right connector or relay. Pair it with an electrical service manual for troubleshooting. For related model parts, see XCMG 810S Series Chassis Assembly Parts Catalog.

106 Pages of OEM Data – No Aftermarket Guesswork

Factory data. Period. Every page matches the physical parts from the Xuzhou Loading Machinery Factory. You won’t find aftermarket substitutions or third-party crossovers. The brake system, steering cylinders, working hydraulic system—all original part numbers. If you need the left steering cylinder seal kit, it’s on page 65. For comparison, check XCMG LW500F Wheel Loader Parts Manual – Section: Frame And Accessories and XCMG GR215A Road Grader Parts Handbook. Both OEM, same factory standard.

For a broader look at equipment documentation standards, read Automotive Industry Overview – but for ZL30G parts, stick with the factory file.

FAQ

Is this the same as a service manual?

No. This is a parts catalog. It lists part numbers and exploded views, not repair steps.

Can I use this catalog to find the correct brake caliper rebuild kit for my ZL30G?

Yes. The brake system section (Z3G.12) includes the disk brake assembly (page 12), air master unit (page 88), and parking brake (page 92). Each diagram has numbered callouts matching the parts list. You can order the exact seal kit or piston for your year and serial number. I’ve used this catalog to find a hard-to-source air tank fitting on page 90. Worked first time.

Factory parts data is the only way to be sure. Access the Factory Manual and keep it on the shop tablet or print the pages you need.
