XCMG XZ16K, XZ50K Parts Catalog – Factory OEM Parts Breakdown

You’ve got a XCMG XZ16K, XZ50K Parts Catalog in your hands. If you’ve ever tried to order a replacement part for a crane chassis and ended up with the wrong bracket or a hydraulic fitting that doesn’t fit, you know the pain. That’s what this manual kills: the guesswork. It’s a 75-page factory document – not a reprint, not a translated summary. Every exploded view, part number, and assembly order comes straight from the Xuzhou Heavy Machinery line. I’ve seen too many techs waste an afternoon cross-referencing parts from aftermarket lists that don’t match. This catalog stops that.

Chassis Sections: What the 75 Pages Cover

The document splits into two chassis sections: XZ16K and XZ50K. Under the XZ16K section, you get 29 numbered chapters starting with the cab assembly (JSQ 驾驶室总成) and running all the way through the outrigger operation system (QY16K.72A). The XZ50K section mirrors much of the same structure but with different part callouts where the chassis differs. Need to find the foot relay valve assembly? That’s chapter 6 in both sections – XZ16K.41.1A. The pages are laid out with engineering drawing numbers, not generic icons. You see the beam wires? Chapter 3 covers the exact harness routing and the battery box shows up in chapter 4. If you’re replacing a radiator, chapter 11 (XZ16K.48A) gives you the radiator assembly and all its mounting hardware. Every part is indexed with the factory part number, not a vague description.

Torque Specs and Fluid Capacities – Where Are They?

This is a parts catalog, not a service manual, so don’t expect torque values for every bolt. But the component breakdowns include the hardware that holds things together – bolts, nuts, washers, seals. If you’re rebuilding a front axle (chapter 15, XZ16K.54A), you’ll see every bearing, shim, and flange listed. For fluid capacities, you’ll find the hydraulic oil tank (chapter 26, QY16K.66) and its support (chapter 27) with the tank part numbers. You still need a separate service manual for capacity specs and tightening sequences. But for ordering the right oil pump (chapter 13, XZ16K.51A) or transmission shaft (chapter 14, XZ16K.53A), this catalog is the only source you should trust.

Does This Manual Cover the Fuel System and Air Brakes?

Yes. The fuel tank assembly is chapter 9 (XZ16K.46A). The air reservoir assembly is chapter 5 (XZ16K.39A), and the air circuit pipe assembly is chapter 7 (XZ16K.42A). If you’re working on a brake system that uses relay valves, the foot relay valve in chapter 6 gives you the exact part numbers for the valve itself and the mounting plate. The air filter installation (chapter 22, XZ16K.67) shows the filter housing and element part numbers. These are the same parts you’d order from an XCMG dealer – no guesses.

Source Validity – Why OEM Beats Aftermarket

This catalog is a direct scan from the Chinese factory binder – the original file is named XCMG_XZ16K-XZ50K_Parts_Catalog_zh-106414018383.pdf. It’s printed by XCMG (徐州工程机械集团有限公司) and verified by their commercial vehicle division. I would not touch an aftermarket parts list for construction equipment. Aftermarket catalogs often renumber parts, combine assemblies, or omit the revision level. This one has the factory engineering codes like XZ16K.25A for the lighting system – a code that matches the physical stamp on the harness. That’s how you avoid ordering the wrong headlight bracket for a 2021 chassis.

3 Reasons to Choose This Factory Parts Catalog

• Every part in the cab, chassis, steering, suspension, hydraulic, and electrical systems has the original XCMG part number.
• The exploded diagrams show the assembly order – a must when you’re rebuilding a central revolving body (chapter 28, QY16K.70) or an outrigger operation system (chapter 29, QY16K.72A).
• 75 pages means you have complete coverage of both XZ16K and XZ50K chassis without flipping between separate books.

Who Should Use This Manual

If you own a crane with an XZ16K or XZ50K chassis and you’re doing your own parts ordering – or if you manage a fleet and need to cross-reference part numbers for multiple units – this catalog belongs on your bench. A beginner can use it: the tables are straightforward, and the diagrams label each item. But you still need to know basic tool handling and safety. For example, when replacing the muffler (chapter 10, XZ16K.47A), confirm the gasket part number before you order. The page for the muffler install includes the bracket and clamp. Do not substitute generic exhaust clamps – the factory bracket matches the frame hole pattern.

FAQ

Can I find torque specs for the suspension bolts in this catalog?

You will not find torque values here. This is a parts catalog – it lists the bolts themselves, but not the tightening specs. For that, you need the XCMG service manual for the chassis.

Does it cover the XZ50K model completely?

Yes, the second half of the 75 pages is dedicated to the XZ50K chassis. The chapter structure is nearly identical, but part numbers differ where the chassis was upgraded.

What if the part I need is not in the table of contents?

Check again – the catalog covers 29 chapters for XZ16K and a matching set for XZ50K. That includes the cab, lighting, beam wires, battery box, air reservoir, brake valves, air circuits, engine mounting, fuel tank, muffler, radiator, gearbox, oil pump, transmission shaft, three axles, two suspensions, steering hydraulics, steering system, air filter, transmission operation, A/C unit, carrier piping, hydraulic tank and support, central revolving body, and outrigger controls. If it’s on the chassis, it’s here.

Is this a reprint or a digital scan?

It’s a direct digital scan of the original factory booklet. The pages show the original Chinese headers and part drawings. You can zoom in to read the part numbers clearly.
