Clark-hurth 35C Parts Catalog – Factory OEM Parts Manual

I’ve been turning wrenches in San Antonio for close to three decades, and the one thing that burns my ass worse than a stripped Allen head is ordering the wrong part because some aftermarket cross-reference was pulled out of someone’s tailpipe. You’re here because you’ve got a Clark-hurth 35C wheel loader on the shop floor or in the yard, and you need part numbers that actually match what Clark built. This is the real deal — the Parts Catalog published by Clark Equipment, 260 pages of factory-issued part breakdowns, warranty terms, and serial-number-specific lists. No third-party guessing games.

Warranty and Serial Number Recording – Page 2 Matters

Right on page 2 of this catalog, Clark tells you to record your machine serial number. That’s not decoration — that’s the difference between buying a steering cylinder that fits and one that doesn’t. The catalog lists two engine options — Detroit 472D and Detroit 807B — and corresponds to Publication No. 3334. If you skip writing down that serial number, you’re asking for a return trip to the parts counter. The warranty section (starting page 4) lays out exactly what Clark covers and what they don’t: abuse, accident, failure to maintain, overtime labor premiums, transportation costs. Read it. It’s six months on parts and labor for new machines, six months on replacement parts after installation. That’s the factory line, not some retailer’s spin.

35C Parts Catalog: The Exploded-View Layout

This isn’t a repair manual — it’s a parts catalog. That means you get exploded-view illustrations of every major assembly: transmission, torque converter, axles, hydraulics, steering, brakes, frame, and operator cab. Each part is tagged with a reference number that links to a table of part numbers, descriptions, and quantities. You won’t find torque specs here (get the service manual for that — see CLARK 35C WHEEL LOADER PARTS MANUAL), but you will find the correct part number for that worn-out hydraulic seal or that cracked bucket tooth. The catalog breaks down by system — engine, drivetrain, work equipment — and each section starts with a general view then dives into sub-assemblies. For example, the torque converter section lists the stator, impeller, and turbine as separate parts with individual Clark part numbers. That level of detail stops you from ordering a whole assembly when you only need one bushing.

Engine and Drivetrain Coverage – Detroit Diesel Specifics

The catalog covers both the Detroit 472D and Detroit 807B engines. You get the full parts list for the engine block, cylinder head, fuel system, and cooling. If you’re rebuilding a 35C, you need the piston ring set part number that matches the serial number prefix. The drivetrain section includes the Clark transmission and axles — again, with serial number breaks. This is where OEM documentation saves you hours of cross-referencing. Aftermarket catalogs often combine multiple models into one generic list; Clark’s original separates the 35C from the 45C and 55C. If you need the parts breakdown for the larger models, check Clark Michigan 35C/45C/55C Tractor Shovel Parts Manual for a combined reference, but for strict 35C accuracy, stick with the 3334 publication.

Hydraulic and Electrical – Where Most Errors Happen

Hydraulic components — pumps, valves, cylinders, hoses — are notorious for being misordered because of minor revisions. The Clark catalog includes detail views of the hydraulic control valve stack, showing each spool, spring, and seal with its part number. Same for the electrical system: starters, alternators, switches, and wiring harness segments. If you’re chasing a parasitic draw or a no-start condition, having the factory wiring diagram (in the service manual) is separate — this catalog gives you the part numbers for the components themselves. Use it together with the service manual to pin down exactly what failed.

Source Validity – Why Factory Beats Aftermarket

I’ve seen “reprint” parts catalogs that have the wrong part numbers because they scanned a photocopy of a photocopy. This is a direct reproduction of Clark’s original Publication 3334. The warranty language, the serial number placement, the part numbering format — all match what came out of Clark’s print shop in the U.S.A. (page 3 says “Printed in U.S.A.”). When you compare this to a generic parts list from a third-party website, the differences jump out: aftermarket lists often omit serial number breaks, combine different model years, or leave out the isometric views that show how parts orient in the assembly. With the factory catalog, you know the part number you order will match what Clark installed on the assembly line. If you’re working on a later model Clark-hurth like the L320, see Clark-hurth L320 1991 Parts Catalog – 690 Pages OEM Specs for that specific machine.

FAQ – 4 Questions That Come Up Every Time

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values, clearance specs, and adjustment procedures are in the separate service manual. Use both.

How do I find the part number for a hydraulic pump on a 35C with a Detroit 807B engine?

Locate the machine serial number (stamped on the frame tag). Match it to the serial number range listed in the catalog’s index. Then flip to the hydraulic section — the pump is broken down into drive gear, cover, shaft, and seals. Each sub-component has a Clark part number. The exploded view shows the assembly order.

What if my 35C has a different engine than the two listed?

The catalog only covers the Detroit 472D and 807B. If your machine was repowered with another engine, you’ll need the parts catalog for that engine manufacturer. The rest of the loader’s parts (axles, hydraulics, cab) are still correct for the 35C chassis.

Are the warranty terms in this catalog still applicable to machines out of production?

The warranty language is the original factory warranty from the time of sale. Clark no longer honors it on machines decades old, but the terms help you understand original coverage and what might have been modified under warranty. For current parts support, contact a Clark-hurth dealer.

Parts catalogs don’t get the glory that service manuals do, but they save you from buying the wrong pump, the wrong gasket, or the wrong seal and then staring at it on the bench wondering why it doesn’t fit. This 260-page PDF gives you every part number Clark assigned to the 35C wheel loader — no guesswork, no aftermarket shortcuts, just the factory documentation. If you want to order parts with the confidence that the number you’re writing on the purchase order matches the machine under the lift, this is the file you need.
