Shanghai Diesel Engine SC8DK 2008 Parts Catalog – Factory Specs That Don’t Leave You Guessing

I’ve been turning wrenches for twenty-eight years, and nothing burns my time like a missing part number. You pull a piston, find a cracked ring land, and then spend an hour chasing down which ring pack fits because the aftermarket catalog has three different options and no way to tell which one matches your build date. That’s exactly why this Shanghai Diesel Engine SC8DK 2008 Parts Catalog is sitting on my bench right now. It’s the OEM document, not a reprint from some data-scraping site. 96 pages, publisher is Shanghai Diesel Engine Co., Ltd., dated February 2008. If you work on the SC8DK series – whether it’s the 230Q3 or 260Q3 – you want this on screen or in a binder.

Engine Block Assembly and Gear Chamber – Page Layout and Order Numbers

The catalog opens with the SC8DK230Q3 engine and lists every assembly group by its official part assembly number. For example, the engine block assembly (D02A-000-800) starts on page 1 of the assembly sections. The gear chamber assembly (D02B-000-800) on page 7. Each assembly group has a figure number – Fig.3 covers the flywheel housing assembly and shows which models it fits. If you need the flywheel itself, that’s D06B-000-800 on page 27. The TOC is printed in both English and Chinese, and the page numbers refer to the PDF page order, not the original print pagination. Pay attention to that when you scroll.

Flywheel Housing and Rail Assembly: What You Need to Know

Flywheel housing assembly, D02C-000-800, is listed on page 10. The rail assembly (D02H-000-800) shows up on page 13. These are common failure points on high-hour engines – cracks around the housing bolt holes or rail damage from injector knock. The parts catalog gives you the exact part number for the housing, the fasteners, and the seals. No guessing if the aftermarket housing has the same dowel pin location. It’s the factory number. Use it.

Cylinder Head and Piston Assembly: Factory Numbers You Can Trust

Cylinder head assembly is D04-000-800a, page 17. Piston connecting-rod assembly D05-000-800, page 23. These are assemblies you don’t want to mismatch. The piston connecting-rod assembly includes the wrist pin, circlips, and rod bearings as a set. The catalog lists every component with its own sub-part number. If you need a replacement connecting rod, you look up D05-000-800 and find the rod part number there. I’ve seen guys order a rod for a different SC8DK variant and end up with a journal size that doesn’t fit. This manual kills that headache.

3 Reasons to Choose OEM Documentation Over Aftermarket Reprints

First, this is the actual Shanghai Diesel Engine factory scan. The file name on the source is ShanghaiDieselEngine_SC8DK_2008_Parts_Catalog_en-63914018761.pdf. That’s the original. Aftermarket “catalogs” often renumber parts or omit figures because the source was photocopied from a blurred copy. Second, the part numbers match the engine’s serial number range. The SC8DK230Q3 and SC8DK260Q3 have different intake and exhaust pipe assemblies – D12-000-804 vs D12-000-805 – and the catalog splits them cleanly. Third, the torque references for assembly (though not listed as torque tables) are embedded in the assembly notes. You can cross-reference with the service manual, but having the parts catalog alone keeps your order accurate.

Does This Manual Cover Both SC8DK230Q3 and SC8DK260Q3?

Yes. The table of contents shows two engine order numbers: DBK0812 for the SC8DK230Q3 and DBK0813 for the SC8DK260Q3. Both use the same base block and gear chamber, but there are differences in intake, exhaust, and some electrical components. The catalog lists each engine’s assemblies separately, so you see the D12-000-805 intake pipe for the 260Q3 versus D12-000-804 for the 230Q3. Also includes the turbocharger (D38-000-14) and control unit assembly (D88A-000-805). For the pre-heater, it’s LQT-000AZ on page 84. That’s a common wear part on cold-weather starts.

Control Unit Assembly and Pre-Heater: The Electrical Side

Control unit assembly (D88A-000-805) has its own section on page 82. Pre-heater assembly (LQT-000AZ) on page 84. If you’re wiring in a new ECM or chasing a no-start in freezing temps, these pages give you the connector part numbers and pinout references. It’s not a full wiring diagram, but it tells you which harness connector goes where. Pair it with the service manual for pin voltages.

Oil Pipeline Assembly and Fig.20 Components

Fig.20 in the catalog shows parts and components for the oil pipeline assembly, D19-000-40 on page 52. That’s the oil supply line from the block to the turbocharger and the oil cooler. If you’re replacing O-rings or the entire line, you get the exact part number for the banjo bolt, crush washers, and the pipe itself. No chasing a dealer for “that little copper washer that always leaks.”

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and assembly relationships. Torque values are in the separate service manual for the SC8DK series.

How many pages is the PDF?

96 pages. All scanned from the original 2008 print.

Will this help me order parts for a 230Q3 engine built in 2009?

Yes, as long as the engine is within the 2008 production run. The SC8DK series had minor revisions; check your engine serial number against the catalog’s applicability notes. The catalog covers both Q3 variants, but later engineering changes might not be reflected.

Can I use this to identify parts for a generator set using the SC8DK?

Probably. The base engine assemblies are identical for industrial and generator applications, but the application page (D00-000-805 on page 86) shows the engine as used in various setups. If the gen-set has a different flywheel housing or air compressor, verify with the gen-set manufacturer first.

Look, I’ve seen too many jobs stall because somebody ordered a piston set for the wrong SC8DK variant. Don’t be that guy. Grab the factory document, look up the assembly number from the engine’s data plate, and order the right part the first time.
