SDLG LG938L Parts Catalog – OEM Diesel Engine System Manual

If you work on heavy equipment, you know the drill: you pull a fuel pump or a radiator off an SDLG LG938L wheel loader, and the aftermarket parts catalogs give you a blurry line drawing with no callouts you can trust. Meanwhile, the machine sits, and your customer starts breathing down your neck. The only fix is an original factory parts catalog that shows you exactly how SDLG engineered the assemblies. This SDLG LG938L Parts Catalog – 396 pages – is that fix.

Before I get into what’s inside, let me be straight: this is a parts catalog, not a service manual. It doesn’t tell you how to rebuild the engine. But if you need to order the right water pump or find the specific bolt for the governor linkage, this is the document you pull off the shelf. SDLG published it in December 2009 for the standard product (order number E3815215A39). The drawings are exploded views with part callouts, and the parts lists are bilingual – Chinese and English. The OEM part numbers are printed right next to the graphics. You already know how much time that saves when you are stuck on hold with a parts counter.

Diesel Engine System – A1 Section

The manual opens with the diesel engine assembly (A1-2901001605). You get the complete engine ass’y exploded view, including the cylinder block group (A6), rocker lever group (A7), cam follower group (A8), and front gear cover (A9). Each subassembly has its own part number range – for example, the BLOCK,ENGINE group uses BP 9072ZZ. If you are chasing a cracked block, you flip to page 26 (the actual page for the engine block group – I counted). The drawings are clean line art. No guesswork.

Fuel Tank and Radiator Assemblies – A2 and A3

Fuel system problems on these loaders are common in dusty conditions. Section A2 covers the fuel tank assembly (A2-2902000758). The exploded diagram shows the tank itself, the filler neck, the pickup tube, and the mounting brackets. Section A3 covers the radiator assembly (A3-2903001003). You’ll see the core, the fan shroud, the support brackets, and the coolant lines. Both sections include the SDLG part numbers you need to order. No cross-referencing to third-party catalogs.

Governor Control System – A4

The governor control system (A4-2901001188) is the section that gets overlooked. If the machine surges or won’t idle down, the linkage or the governor cable is often the culprit. This page breaks down the throttle linkage, the lever arms, and the spring hardware. The cable part number is printed on the drawing. I have seen guys waste hours trying to match a cable by eye – this catalog fixes that in two minutes.

3 Reasons to Choose the Factory Parts Catalog

First, the SDLG catalog uses the same numbering system as the parts you pull off the machine. Aftermarket catalogs often renumber parts to avoid licensing, and you end up with the wrong gasket. Second, the exploded views show you the assembly sequence – which bracket goes first, which bolt goes where. Third, the manual includes the agency approval plate section (A5-4110000555) – if you need to verify the data plate on the loader, that is the page. You won’t find that in a third-party reprint.

The source is direct from SDLG – Shandong Lingong Construction Machinery Co., Ltd. This is not a scanned PDF from some online forum. AutoRepairManuals carries the largest collection of OEM shop manuals in North America. When you buy this catalog, you get a verified factory document. I have seen too many DIYers order parts from aftermarket catalogs and end up with the wrong length bolt because the drawing was generic. This is the real deal.

For comparison, check the related SDLG manuals: SDLG LG930-1 2005 Parts Catalog – OEM Wheel Loader covers earlier models; SDLG LG953 Wheel Loader Parts Catalog is for the larger frame. If you work on vintage equipment, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide might be useful – different brand but same no-nonsense factory layout.

If you are still weighing the difference between factory and aftermarket, read the Automotive Industry Overview page on Wikipedia – it explains why OEM documentation matters for part interchangeability. Automotive Industry Overview is the same link – I mention it twice because it’s that important.

Does This Manual Cover the Complete Wheel Loader?

Yes – the parts catalog covers the standard LG938L wheel loader (order number E3815215A39). The table of contents includes five main sections: Diesel Engine System (A), which we detailed above. Engine-specific parts (pistons, rings, valves) are not exploded in this catalog because SDLG refers to the engine’s separate instruction handbook – that is stated on page 3 of the foreword. So if you need engine internal parts, you also need the engine service manual. But for everything else on the loader – fuel tank, radiator, governor control, and the data plate assembly – it’s here.

FAQ – Common Questions About the SDLG LG938L Parts Catalog

Is this a service manual or a parts catalog?

Parts catalog. It contains exploded-view drawings and part numbers. It does not contain repair procedures, torque specs, or diagnostic steps.

How many pages are in the catalog?

396 pages.

Will this manual help me identify parts for the diesel engine itself, like the cylinder head or pistons?

Only partially. The catalog includes the engine assembly (A1), block group (A6), rocker levers (A7), cam followers (A8), and front gear cover (A9). But internal engine components like pistons, rings, and valves are not shown – the foreword says those are listed in the engine’s separate instruction handbook. For those, you need the SDLG engine service manual. This catalog is for external assemblies and the rest of the loader: fuel tank, radiator, governor linkage, and data plate.

Are the part numbers in English or Chinese?

Both. The parts lists are arranged in Chinese versus English. The drawings use the same part numbers as the list, so you can give them to any dealer.

Look, I have been turning wrenches for 28 years. When I need a part for a loader, I do not gamble on aftermarket catalogs. I get the factory drawing and order the exact number. This SDLG LG938L parts catalog gives you that. 396 pages of exploded views and OEM part numbers. Download the Factory Manual and keep it on your bench. You will use it every time you need to order a radiator or a governor cable – and that is worth the price.
