Xuzhou Construction Machinery GR.1, GR. 1. 21, GR. 19, GR. 9. 1, GR.2 Parts Catalog

If you’re rebuilding a Xuzhou Construction Machinery GR.1, GR. 1. 21, GR. 19, GR. 9. 1, GR.2 Parts Catalog grader, you need factory part numbers. Aftermarket cross-references get you halfway – then you’re stuck with a bolt that’s two millimeters too short. This is the original Parts Catalog from Xuzhou Construction Machinery. 164 pages of exploded diagrams and code listings. I’ve seen techs order the wrong steering axle because they used a generic list. Don’t be that guy.

Engine System Coverage – GR. 1 and GR. 19

Page 7 kicks off with the main engine system (GR. 1) – includes the block, mounts, and attached components. GR. 19 (page 17) covers the engine operate group: throttle linkages, support brackets, and fasteners. The Engine section also includes the engine mantle (GR. 2) on page 24, which is the outer sheet metal and insulation. If you need a water pump gasket or a crankshaft pulley, this catalog gives you the exact OEM code. No guessing.

Cooling System: GR. 1. 21 Fan Assembly

The fan drive and Cooling system live on page 11 under code GR. 1. 21. Diagram shows the fan blade, hub, pulley, and belt routing. If your GR. 1. 21 is overheating, the part number for the fan clutch or shroud is right there. This isn’t a service manual – don’t expect torque specs – but for ordering the correct replacement fan, it beats any aftermarket catalog I’ve seen.

Hydraulic Systems – Are They Covered?

Yes, multiple sections. GR. 6 (page 42) is the work equipment hydraulic system – pump, valve bank, cylinders. GR. 8 (page 53) is steering hydraulics; GR. 15 (page 57) is braking hydraulics. Later pages (128–164) cover the GR215A variants with front wheel assist and fan drive hydraulics. For a primer on how these systems interact, check Hydraulic systems background. But for part numbers, this catalog is the source.

7 Major System Sections in This 164-Page Catalog

Engine, Cooling, Steering, Braking, Electrical, Attachments, Transmission. Each section has multiple subsections. Electric system (page 66) includes instrument box (page 70) and control box (page 73). Transmission system appears as GR. III. 20 on page 124. The rear scarifier (GR. 25, page 104) and front dozer (GR. 26, page 107) are covered, plus snow-sweeping equipment (GR. 11, page 110). That’s a lot of ground in one book.

Get the Right Part: Why Factory OEM Specs Matter

This catalog comes directly from Xuzhou Construction Machinery. Aftermarket parts manuals often merge multiple models into one blurry diagram. Here, each model – GR.1, GR. 1. 21, GR. 19, GR. 9. 1, GR.2 – has its own code prefix. Look up the steering axle on page 76 (GR. 17) and you get a unique part number for the tie rod, kingpin, and wheel bearing. If you need a part for a different Xuzhou machine, see Xuzhou Construction Machinery Works YL16, YL20 Parts Catalog – 151 Pages or the Xuzhou XS160 XS190 Parts Catalog – Factory Specs. For a broader view of how construction equipment is built, the Automotive Industry Overview is helpful context.

Audience Fit – Who Needs This Catalog?

If you own a GR series grader, run a small fleet, or work in a rental yard, this saves hours of hunting for part numbers. It also includes optional attachments: snow-sweeping equipment, rear scarifier, front dozer. The control box diagram (page 73) is gold for electrical troubleshooting. Another related manual that pairs well with this is the Xuzhou XSM218 XSM220 Parts Catalog – OEM Factory Specs.

Does this catalog include torque specifications for assembly?

No. This is a parts catalog, not a service manual. Torque spec data is not listed.

Are the part numbers in this catalog interchangeable with other brands?

Factory part numbers from Xuzhou Construction Machinery are designed for GR series machines. Using cross-references from aftermarket suppliers can lead to mismatched components. For example, the steering axle GR.17 includes specific seals and bearings that generic substitutes may not match. The catalog provides the exact OEM code, so you order from the manufacturer or authorized dealer. If you are attempting to fit a part from another brand, you will need to verify dimensions yourself – this catalog does not provide that data.

What pages cover the cooling system?

Page 11 covers GR. 1. 21 cooling fan device. Additional cooling components appear in the engine system section starting page 7.

Can I use this catalog for the GR215A models?

Yes, the catalog includes sections specific to GR215A. See pages 128-164 for hydraulic and electrical system parts for that variant.

When you need to rebuild a GR grader, start with the right part numbers. Access the Factory Manual from AutoRepairManuals and keep it on your bench.
