Jinma 600, 604 Parts Catalog

If you’ve ever tried to order a clutch disc for a Jinma and got the wrong size because the aftermarket catalog showed a generic picture, you know the pain. You end up with a box of metal that doesn’t fit, the tractor sits, and you lose a Saturday. This Jinma 600, 604 Parts Catalog is the factory document – 110 pages of exploded views and OEM part numbers pulled straight from Jinma’s engineering department. Not a reprint, not a scan of a scan. I’ve been torquing bolts for 28 years, and I can tell you: without the right part number, you’re guessing. And guessing costs money.

Air Filter Assembly (I) Through (III) – Three Different Configurations

Look at the table of contents. You’ll see Air Filter Assembly (I) on page 3, (II) on page 4, and (III) on page 5. That’s not redundancy – that’s three distinct filter setups used on Jinma 600 and 604 tractors depending on the build year and emission requirements. One uses a dry element, another an oil-bath, and the third a pre-cleaner stack. The catalog shows each with a separate exploded diagram and callouts. If you order by eye instead of by these pages, you’ll end up with a filter that clogs in 50 hours. I’ve seen it.

Cooling System and Exhaust System: Gaskets and Manifold Parts

The cooling system assembly (page 6) covers the radiator, fan shroud, hoses, and water pump with individual part numbers. The exhaust section (page 8) includes the manifold, muffler, and flange gasket – note there are two different manifold gasket part numbers depending on whether you have a 600 or a 604. The catalog distinguishes them by a suffix in the part number. You won’t find that in a generic parts list.

Single Stage vs Dual Stage Clutch – Know Which You Have

Pages 11 through 16 break down both clutch types. Single stage (page 11 and 12) uses one driven plate for direct drive. Dual stage (page 14 and 16) has two plates for independent PTO and transmission engagement. The part numbers for the release bearing, pressure plate, and disc are different between the two. Order the dual stage disc for a single stage tractor and you’ll have a clutch that won’t disengage. Page 11 and page 14 show the differences in the hub spline count. Measure before you call the supplier.

Front Axle Arm, Front Wheel Hub, and Steering Tie Rod

The front axle assembly (page 20) gives you the kingpin, bushings, and steering arm parts. Drag link and tie rod (page 22) includes the ball joint ends – and there’s a separate page for the four-wheel drive tie rod (page 25). If you have a 604 with front-wheel drive, you need that section to get the correct tie rod length. The front central drive (pages 27 and 29) and front final drive (page 31) cover the differential and axle shafts for the 4WD model. That’s 110 pages of this kind of detail.

Source Authenticity: OEM Print, Not Aftermarket

I’ve seen aftermarket parts catalogs for Jinma tractors that combine the 600 and 604 into one generic list – then you get a part number that doesn’t exist. This file is the original factory PDF from the Automotive Industry Overview, but sourced directly from Jinma’s distributor documentation. It’s the same binder the dealer uses. No reprints, no third-party edits. If the part number is on page 34 (Directive Wheel), it’s the same number Jinma stamped on the casting. Automotive Industry Overview

Frequently Asked Questions

Will this parts catalog tell me the torque specs for the cylinder head?

No. This is a parts catalog, not a service manual. It shows part numbers and exploded views. You need the separate Jinma repair manual for torque values.

Does the catalog cover both two-wheel drive and four-wheel drive models?

Yes. The 600 is 2WD, the 604 is 4WD. The catalog has separate sections for the front central drive (page 27, 29) and front final drive (page 31) that apply only to the 604. Also the tie rod page 25 is specifically for the four-wheel drive version.

How do I know if the part numbers are still current?

Jinma uses a consistent numbering system. The catalog was published for the 60 hp range. Some parts may have supersessions, but the exploded diagram shows the exact assembly. You can cross-reference the number with a dealer.

I need a part for the engine control mechanism (page 9). Does the manual show the throttle lever and linkage?

Page 9 covers the engine control mechanism assembly – throttle lever, rod, spring, and mounting bracket with separate callouts for each piece. The part numbers for the 600 and 604 are identical for that assembly. If you need the hand throttle cable, the part number is listed with the control mechanism, not the chassis section.

You can keep guessing with aftermarket photos, or you can use the same factory parts catalog the dealers rely on. Access the Factory Manual now and get the right part the first time.
