Sisu Diesel 44 CTA-2v, 61676, 76219, 90/2500 Parts Catalog – OEM Factory Spares PDF

If you’re ordering parts for a Sisu Diesel 44 CTA-2v and you’re working off a third-party list, stop. You’ll end up with the wrong gasket, a mismatched crankshaft bearing, or a cylinder head that doesn’t bolt on. I’ve seen it happen. That’s why this Sisu Diesel 44 CTA-2v, 61676, 76219, 90/2500 Parts Catalog exists. It’s the same 41-page book the dealer uses, straight from Nokia, Finland.

What’s Inside the 41-Page Parts Catalog

Every section in this catalog is organized by engine assembly. You get exact part numbers in Finnish, Swedish, English, and German. The table of contents lists 19 chapters: Cylinder block, Gear housing, Flywheel, Crankshaft (Kampikoneisto/Vevmekanism), Valve mechanism, Cylinder head, Inlet and exhaust manifold, Turbo piping, Oil sump, Oil filter, Coolant pump, Fuel pump, Fuel filter, EEM3 parts, Alternator, Starter motor, Bearings undersize, and Engine repair parts. That’s the full breakdown you need to order correct spares.

3 Reasons to Use the Original OEM Document

Aftermarket catalogs reindex parts, drop notes like “+Laakeriholkki” (bush included in assembly), and ignore engine number cutoffs. This original Sisu Diesel publication marks exactly when a part changes – for example, from engine number S 21860 onward on the 44 76219 U 1001 variant. You also get the OEM code for repair kits: “K = osat kuuluvat korjaussarjaan sivun lopussa” means the part is included in the repair kit at the end of the page. No guessing which bolts come with the valve cover gasket.

How to Cross-Reference by Engine Number

Page 2 of the catalog explains the drawing symbols. S1 and S2 designate parts in gasket set I/II. A star with slash (“/ *8”) tells you to see page 8 for torque or extra info. The engine number is printed right on the front cover: for the Hesston Windrower application, it’s 90/2500. You need that number to match your block to the correct cylinder head version. Without it, you’re rolling dice.

Cylinder, Crankshaft, and Valve Assemblies

The cylinder block section (chapter 1) lists part number 8367 66377 for the block itself. The crankshaft chapter (chapter 4) includes bearing undersize sets in chapter 18 – separate from the standard bearings. Valve mechanism parts are in chapter 5. If you’re rebuilding a head, you pull the part number for the valve guide from that chapter and order the corresponding seal from the repair kit list. No need to measure anything twice if the catalog says “L = pituus” (length) and you’ve got the right engine number.

Who Needs This Catalog

If you own a Hesston windrower with a Sisu 44 series, or you maintain a fleet of forestry equipment using the 61676/76219 engines, this is the only document that gives you the correct part for the job. Homesteaders and small-shop mechanics who buy aftermarket “will-fit” parts often find the oil sump gasket is 2 mm too short. The factory catalog eliminates that. You get the exact oil sump chapter (chapters 9/10), the coolant pump chapter (12), and the EEM3 electronic control parts (15). Use the OEM reference numbers when calling your dealer – they’ll ship the right box the first time.

Source Authenticity: Factory Sisu Diesel, Not a Reprint

This PDF is scanned from the original Sisu Diesel Oy publication printed in Nokia, Finland. The header on every page reads “SisuDiesel 44 CTA-2v” and the footer shows the phone/fax of Sisu Diesel Inc. Compare that to aftermarket reprints that omit the instruction page (page 2) or the Finnish/Swedish notes – those notes tell you which bolts are included in the assembly (“+Ruuvi = osa sisältyy kokoonpanoon”). The factory document is complete. If you need to verify the fuel pump part number, this Wikipedia article on diesel engines explains the injection system basics, but the actual part number is on page 12 of the catalog.

FAQ

Does this catalog cover the 44 CTA-2v with the EEM3 control system?

Yes. Chapter 15 is specifically titled “EEM3 osat / EEM3 parts” and lists all electronic control components.

How do I find the correct crankshaft bearing undersize?

Chapter 18 (Laakerien alikoot / Bearings undersize) lists available undersize sets. You need your engine number – the 44 76219 U 1001 starts at S 21860 – to match the crankshaft journal dimension. If the catalog says “L = pituus” for a bearing, verify the length against your measured journal.

What models are included in this 41-page catalog?

Three engine variants: 44 CTA-2v 61676, 44 CTA-2v 76219 U 1001, and 90/2500 for Hesston windrower application.

Can I use this to order parts for a non-Hesston application of the 44 CTA-2v?

Yes. The catalog covers the base engine. The only application-specific listing is for the Hesston windrower (90/2500), but the core engine assemblies – cylinder, crankshaft, valve, fuel system – are the same across all builds. Just confirm your engine number against the cutoff listed on page 2.

You need the right part numbers before you pick up a wrench. Access the Factory Manual and keep a copy on the shop tablet. Your engine – and your wallet – will thank you.
