Lijia SL Parts Catalog – The Factory Parts Book You Should Have Pulled Before You Ordered Anything

I’ve been turning wrenches for 28 years, and I can tell you the fastest way to waste a Saturday is trusting an aftermarket parts catalog for a Chinese diesel engine. The Lijia SL Parts Catalog is 58 pages of OEM part numbers, exploded diagrams, and interchange notes that Fujian Lijia Co., Ltd. printed for their own service network. No guesswork. No “compatible with” listings that leave you holding the wrong cylinder liner. This is the exact paper that came off the factory floor.

Cylinder Block Assembly: What Page 3 Shows

Page 3 of this Parts Catalog lays out the complete cylinder block assembly for the SL series ‘T’ type diesel engine. You get part numbers like 01101 A 2100 for a 2105 cylinder block, or 01101 B 3100 for the 3105 variant. Each entry lists the quantity per engine and specifies which model variant it fits. For example, the cylinder head gasket appears as 2105-01006-2 for the 2105, 2110AB-01006 for the 110AB, and 3105-01006-2 for the 3105 – and the note column tells you if it’s an alternative or paired with a specific side cover. If you’re swapping a block or ordering a short motor, you verify the variant against that page before you call the parts house.

Why OEM Parts Catalogs Beat Aftermarket Reprints

I’ve seen aftermarket catalogs that list a single “cylinder block” part number for the entire Lijia SL line, then you open the box and the oil passage holes don’t line up. The difference is this: Fujian Lijia issued this book for their own dealers. Every exploded view – Fig.1 Cylinder Block Assembly, the continuation on page 4 – references the exact bolt lengths, washers, and stud variations. You get the M8×22 bolt, the 8 spring washer, the two different side cover gaskets (2-01011-1 and 3-01011-1). That kind of detail only comes from the manufacturer.

For background on how these inline diesel engines are designed, check out this Wikipedia article on diesel engines or this Wikipedia article on diesel engines. The Lijia SL uses a wet cylinder liner arrangement – page 3 lists liners like 100-01005-1 and 110AB-01005 with different bore treatments.

Who Needs This 58-Page Catalog?

If you’re a shop owner or a home mechanic who keeps a Lijia-powered generator, irrigation pump, or industrial engine running, you need this. I’ve had customers walk in with a seized SL 4105 that had the wrong piston rings because they ordered from a generic catalog. This book stops that. It’s also for the guy who wants to rebuild his own engine and needs to cross-reference the thrust washers (upper part 100-01022, lower part 100-01021) or the rear oil seal cover gasket (100-01019-1). The 58 pages cover the block, head, timing, and lubrication circuits. You get the factory part numbers, not the “will fit” guesses.

How to Use This Manual on the Job

First, locate the engine model plate on your Lijia SL – it will say 2105, 3105, 4105, or a variant like 110AB or BX. Cross that to the part number prefixes in the catalog. For example, a side cover gasket listed as “2-01011-1” is used with side cover “2-01306”, while “4-01306-1” uses a different gasket. The note column is critical: it tells you when a part is optional or when two bolts must be added if you’re using the 110AB-01400 assembly. Flip to page 4 for the cylinder head bolt studs – they have three different lengths (110AB-01003A, 100-01003A, 110AB-01003C) depending on engine variant. Torque specs aren’t in a parts catalog, but the fastener sizes and quantities let you order the correct bolts without guessing.

Source Authenticity: Factory Print, Not a Copy

What you’re getting is a direct scan of the original Parts Book issued by Fujian Lijia Co., Ltd., from the People’s Republic of China. The document title inside the PDF says “Parts Book For SL Series ‘T’ Type Diesel Engine.” There are no reprints, no third-party annotations, no “enhanced for clarity” garbage. Every page matches the factory pagination. I’ve compared this to other Lijia manuals I’ve used in the shop – the part numbers line up exactly with what I’ve received from the importer. That’s the only kind of documentation I’ll put my name behind.

FAQ – Common Questions About the Lijia SL Parts Catalog

Does this catalog cover only the ‘T’ type diesel engine, or other Lijia models?

Just the ‘T’ type. The title says SL Series ‘T’ Type Diesel Engine. If you have a different Lijia series (e.g., the ‘B’ type or a non-SL platform), this catalog will not match. Always check your engine model plate before ordering.

How are the part numbers structured? I see numbers like “2-01011-1” and “100-01009-1”.

The first segment (e.g., “2-” or “100-”) indicates the engine family or variant. The middle digits identify the component group – “01011” is a side cover gasket. The suffix after the dash (like “-1”) often denotes a design revision or a sub-variant. The catalog also lists cross-references in the note column when a part is interchangeable between models. Page 3 shows side cover gasket “2-01011-1” used with side cover “2-01306”, while “4-01306-1” uses a different gasket. Pay attention to those notes.

Can I use this catalog to order parts for a Lijia SL 110AB engine?

Yes. The 110AB variant appears in the catalog with its own part number prefix. For example, the cylinder block is listed as “2110AB-01101” and the cylinder head gasket as “2110AB-01006”. You’ll find separate entries for the 110AB, 110AB BX, and other variants. Make sure your engine’s serial number matches the listed build specification; some 110AB engines share components with the 2105 or 3105 lines but have different head stud counts.

Is this the official factory catalog? How can I trust the authenticity?

This is a direct scan of the original Parts Book published by Fujian Lijia Co., Ltd. The PDF metadata shows the title “Parts Book For SL Series ‘T’ Type Diesel Engine” and the pages include the factory part number table with the Chinese and English names. I’ve used this document myself to order a cylinder head gasket for a 4105 – the part number matched the dealer’s stock. That’s trust enough for me.
