Sisudiesel 620 DSRE Parts Catalog – OEM Spare Parts Guide

You’ve got a SisuDiesel 620 DSRE on the stand, halfway through a rebuild, and you need the right piston ring or a cylinder liner. Generic aftermarket catalogs give you fuzzy drawings and part numbers that don’t match. That’s a waste of time and money. This Sisudiesel 620 DSRE Parts Catalog is the exact same binder the factory hands to its parts counter. 30 pages of exploded diagrams, OEM part numbers, and cross-references to gasket sets and repair kits. No translation errors, no reprints – just the original Finnish/Swedish/English/German document scanned from SisuDiesel’s own archives.

I’ve used these catalogs for years in my shop. When a customer brings in an old diesel, you don’t guess the part. You pull the catalog, read the reference numbers, and order once. That’s professionalism. This manual covers the cylinder block group, cylinder block with equipment, and includes the notations for gasket set I/II and repair kit components. Page 3 alone lists every bushing, screw, and O-ring in the block assembly. Need a lagerhylsa (bushing)? It’s right there: part number 8368 66069. Don’t rely on memory – use the factory spec.

What’s Inside the 30-Page Catalog

Every page is a dense table of part numbers, quantities, and descriptions. The first two pages explain the symbol system: S1/S2 for gasket sets, K for repair kits at the end of the page, and the “+” sign for parts included in an assembly. The manual is multilingual – you’ll see Swedish, Finnish, German, and English. If you’ve never decoded a European parts list, take five minutes to read page 2. It saves you from ordering a plug when you need a stopfen.

The main content splits into two major sections. First, the cylinder block (page 3) shows the block itself, bearing covers, guide sleeves, cylinder liners, and all fasteners. Second, the cylinder block with equipment (page 4) adds the front cover, oil pan details, and accessory drives. Each row gives you the order number (tilaus nro), quantity, part name in four languages, and a reference column for notes like “see page 8” or “from engine number M 7059”. That engine number cut-off is critical – some parts changed after serial M 7059.

Cylinder Block Assembly – Page 3 Breakdown

Start with reference 1: the cylinder block assembly itself (part 8368 66110). From there you trace down to the bearing caps (lagerlock), guide sleeves, and the six cylinder liners (8366 66990). Each O-ring has a separate part number – S2 indicates it belongs to gasket set II. If you’re replacing liners, you need both O-rings (ref 13 and 14). Don’t forget the plugs on the block – ref 15 and 16. Page 3 also lists the shaft (8361 29709) and gear (8361 29863) for the balance shaft drive. All screws are called out with thread size: M10 x 55, M14 x 65.

Gasket Sets and Repair Kits – Notations You Can’t Ignore

Look at the top of each parts list. You’ll see symbols like S1, S2, and K. Those tie directly to the gasket set I/II and repair kits at the back of the catalog. If you order a top-end gasket set, verify the part numbers in this catalog match the S1/S2 items. The repair kit (marked K) includes the specific bushings, seals, and small parts needed for a major overhaul. Without this catalog, you might buy a generic kit and find out the hard way that the oil plug is the wrong thread pitch. this Wikipedia article on diesel engines explains the basics, but for part numbers you need factory documentation.

Does This Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. It lists what to buy, not how to install. For torque values, you want the separate SisuDiesel 620 DSRE service manual. But that doesn’t make this catalog useless – if you’re rebuilding, you need both. Use this catalog to order the correct bolt, then use the service manual for the torque sequence. Don’t skip either step.

7 Tips for Using This Catalog Effectively

First, check the engine number on page 1. If your engine is after M 7059, some part numbers changed. Second, always look at the “Huom.” column – that’s where notes like “pituus” (length) or “X” (as needed) appear. Third, when ordering, quote the 10-digit order number, not the figure number. Fourth, if a part has a “+” sign, it’s included in a higher assembly – don’t double-order. Fifth, use the K-marked repair kits for full overhauls rather than buying individual pieces. Sixth, confirm O-rings are from the correct gasket set (S1 or S2). Seventh, keep a printed copy at your workbench – digital screens get greasy.

One more thing: cross-reference with other SisuDiesel models. The cylinder block on the 620 DSRE shares components with the SisuDiesel 645 DSBIE Spare Parts Catalogue and SisuDiesel 634 DSBIE Spare Parts Catalogue. If you’re swapping parts, verify the order numbers match. The SisuDiesel 420 DSRE Spare Parts Catalogue might also have common fasteners.

Why OEM Beats Aftermarket Parts Catalogs

Aftermarket catalogs re-draw the diagrams and often miss critical notes like “see page 8” or “from engine number”. They also drop the multilingual descriptions, which hides important specifiers like “lagerhylsa” vs “bushing” – they mean the same thing, but the aftermarket might mix up the thread. This catalog is a direct scan of SisuDiesel’s own 30-page document, including the original logo and contact info for Sisu Diesel Oy. No reprints. No copy-paste errors. You get the exact data the factory uses.

FAQ

What is the difference between a parts catalog and a service manual?

A parts catalog lists every component with order numbers, quantities, and cross-references to gasket sets. A service manual gives you removal/installation steps and torque specs. You need both for a full rebuild.

Does this catalog include torque values?

No. Only part numbers and assembly references.

Is this catalog available completely in English?

The part names appear in four languages: Finnish, Swedish, English, German. The column headers and notes are also in those languages. If you can read basic English, you’ll be fine. The gasket set notations (S1, S2, K) are universal.

Can I use this to rebuild my engine?

Only for ordering parts. The catalog does not tell you how to install them. Pair it with the official SisuDiesel service manual. But without this catalog, you risk buying wrong O-rings or missing a $2 plug that causes an oil leak. I’ve seen it happen.

This isn’t a generic PDF obtained from some forum. It’s the factory parts list for the SisuDiesel 620 DSRE – 30 pages of verified OEM data.
