Longagribusiness 410 DTC, 450, 450 DTC, 470 DTC, 530 DTC 2002 Parts Catalog

If you’ve ever ordered a water pump for a 470 DTC and got one that didn’t fit because the parts guy used an aftermarket cross-reference, you know the pain. I’ve been wrenching on these Landtrac tractors since the early 2000s, and the difference between a factory Parts Catalog and a cheap reprint is the difference between a running machine and a lawn ornament. This 2002 OEM manual covers the 410 DTC, 450, 450 DTC, 470 DTC, and 530 DTC – all 377 pages of factory-sourced part numbers, exploded diagrams, and the exact sub-assembly breakdowns you need to order the right stuff the first time.

Cooling System: Radiator and Cooling System Parts (Pages 3-6)

Cooling system failures on these tractors usually boil down to a clogged radiator or a bad water pump. Page 3 gives you the full Cooling System layout – fan, pulley, belt, thermostat housing – with factory part numbers. Page 5 shows the radiator assembly for the 410 DTC through 530 DTC. Don’t waste half a Saturday matching up a Chinese radiator from NAPA; get the Longagribusiness OEM number from this manual and call it done.

Engine Section: Cylinder Head, Valve Mechanism, and Crankcase

Pages 7-26 are pure gold if you’re splitting the block. The Engine Section breaks down the Cylinder Head (7-8), Valve Mechanism (9-10), Rocker Cover & Camshaft (11-12), Crankcase (13-14), Timing Gear Case & Timing Gear (17-18), and Main Moving Parts (21-22). Every gasket, every bolt, every oil seal has a factory part number. When you’re ordering a head gasket for a 450 DTC, you want the OEM number, not some aftermarket “fits all” number that leaks after 50 hours. This catalog gives you that.

Fuel System: Injection Pump and Nozzle Assembly

Fuel system parts are where aftermarket catalogs really screw you. Pages 29-60 cover the Fuel System in detail: Fuel Injection Pump (General, pages 31-32), Injection Pump (33-36), Nozzle Assembly (37-40), Feed Pump (49-50), Fuel Filter (51-52), and Fuel Tank Assembly (53-56). There’s a separate Governor section for the 410 DTC/450/450 DTC (pages 41-44) and 470 DTC (pages 45-48). If you’re rebuilding a Roosa Master pump on a 530 DTC, you need the correct part numbers for the delivery valve and plunger. This catalog has ’em.

Governor and Injection Pump: 410 DTC/450/450 DTC vs 470 DTC

The governor linkage is different between the two groups. Page 41 shows the governor setup for the 410 DTC, 450, and 450 DTC. Page 45 shows the 470 DTC version. Don’t assume they’re interchangeable – I’ve seen guys install a 470 governor on a 410 and wonder why it revs to 3500 rpm. The exploded views in this Parts Catalog show every spring, lever, and screw. You’ll spot the difference in three seconds.

Audience Fit: When You Need This 377-Page Parts Catalog

You’re a DIY owner-operator who keeps a fleet of Landtrac tractors running, or a small shop that sees these machines regularly. You’re tired of calling Longagribusiness with a VIN and getting a “let me check” that takes 20 minutes. With this catalog on your bench, you look up the part number, call the dealer, and order. No guessing. No “this might fit.” The section for 530 DTC/550/550 DTC (pages 61-102) mirrors the earlier models but with different part numbers for the Cooling system, engine, and fuel system. Check the TOC for the exact page ranges.

Source Validity: Why This Is Not a Third-Party Reprint

This is the original 2002 factory document – PDF from LongAgribusiness, not scanned from a greasy photocopy. The file name “LongAgribusiness_410_DTC-450-450_DTC-470_DTC-530_DTC_2002_Parts_Catalog_Section_NUMERICAL_INDEX_en-97614017212.pdf” tells you it came from the OEM’s own archives. Aftermarket parts catalogs leave out sub-sections like the “ALL MODELS” sections starting page 103 (Air Cleaner, Exhaust System, Clutch, Clutch Housing, Brake and Clutch Controls, Gearbox). Those pages cover parts common across the entire line – you won’t find that in a cheap reprint. I trust this because the part numbers match the bolts I’ve pulled off actual tractors.

FAQ

Does this Parts Catalog include torque specifications for bolts?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. For torque specs, you need the factory service manual for your model.

I have a 530 DTC tractor. Do I need to buy the 530-specific section or does the whole catalog cover it?

The 530 DTC shares some sections with the 550/550 DTC (pages 61-102) but also uses common “ALL MODELS” sections from page 103 onward. The catalog covers all models 410 DTC through 530 DTC, so you get every part number for your tractor in one document. Just use the Table of Contents to find the correct page range – for example, the 530 DTC Cooling System is on pages 63-66, while the 410 DTC version is on pages 3-6. They share the same radiator? No – check the part numbers. The catalog shows the difference.

Ordering the wrong part costs you time and shipping. With this factory Parts Catalog, you match the exploded diagram to what’s on your bench. Access the Factory Manual now and stop guessing part numbers.
