Yale NR035, NR040, NR045, NDR030, NS040 1998 Parts Catalog

I’ve seen enough shops lose billable hours because someone ordered the wrong brake spring or a cylinder seal that didn’t match the mast type. That’s what happens when you rely on aftermarket parts lists or a generic PDF from some third-party site. The Yale NR035, NR040, NR045, NDR030, NS040 1998 Parts Catalog is the real thing—straight from Yale Materials Handling Corp, printed July 1998, 266 pages thick. Every part number, every exploded view, every revision flag is there because the factory stamped it. If you’re rebuilding a reach truck or a straddle unit from this era, you don’t have room for guesswork.

Brake System at Page 4-5

Page 4-5 covers the drive motor brake and the complete brake system. That’s the section you’ll tear out and tape to the bench when you’re swapping pads or replacing a brake solenoid. The catalog shows the exact part numbers for the brake assembly, the drive motor brake, and the caster wheel assembly (page 4-4). No hunting through an alphabetical index hoping the number is right. You flip to page 4-5, you see the diagram, you order the part. Done.

7 Major Systems in This Catalog

The index breaks down every major system: electrical contactors (pages 2-13 through 2-26), hydraulic cylinders (section 6), mast assemblies (section 5), drive unit (section 3), hydraulic control valve (page 7-8), and the hydraulic system itself (page 7-2). Each subsystem has its own page reference. The catalog doesn’t lump everything into one blob—it gives you separate listings for simplex cylinders, triplex masts, battery lift cylinders, and sideshift cylinders. You’ll find the exact part for your specific model variant, whether it’s an NR045 AC or an NS040 AD.

Who Needs This Parts Catalog?

You’re a home-garage mechanic who picked up a used Yale NR035 for the warehouse. Or you run a small shop and your techs are wasting time cross-referencing numbers on eBay. This catalog is for anyone who has ever held a parts manual and thought, “Is this the right seal or not?” With 266 pages of factory data, you’ll know. The alphabetical index runs from Alarm-Back-up (page 8-16) to Roller-Battery (page 1-6). If you need a back-up alarm, an amber revolving light, or a decal set, the page numbers are there.

OEM Yale Documentation vs Aftermarket

Aftermarket parts catalogs copy the diagrams but leave out revision numbers and supersession notes. This one has the original Yale logo, the part number structure from the factory, and the same exploded views the dealer uses. You get the brake system drawing exactly as Yale intended, not a redrawn version that misses a washer. For service specs, pair this catalog with the factory service manual for torque values and procedures. Check the Yale NR035 NR040 NR045 NDR030 NS040 1998 Service Manual for the full repair steps. And for earlier models, look at the Yale NR035 NR045 NDR030 1991 Parts Catalog if you have an older build.

Hydraulic System: What the Manual Covers

Page 7-2 starts the hydraulic system listing: filter, tank, control valve, lift pump, and motor. The index shows two separate entries for Hydraulic Tank (pages 7-14 and 8-16)—that’s because the tank also serves as a reservoir for optional lights. You’ll find part numbers for the hydraulic oil filter (page 7-2), the pump and motor-lift (page 7-8), and the steer pump assembly (page 5-8). No guesswork about which o-ring fits the NR030 AC versus the NS040 AD—the catalog splits them.

I don’t trust aftermarket documentation on principle. I’ve seen a third-party catalog call a 24-volt contactor a 36-volt part and cost a shop $800 in fried electronics. This Yale original doesn’t do that. You get the exact model breakdown: NR 035/040/045 AC, NDR 030 AC (A815), and NS 040/050 AD (A816). The nomenclature on page 2 explains how to decode the serial number to confirm mast type and voltage.

Before you order a brake motor or a contactor, check page 4-5 and page 2-13 (Contactor-Power Steering). Then cross-reference with the Yale NR035, NR040, NR045, NDR030, NS040 1996 Service Manual if you need the removal procedure. For a broader look at the Automotive Industry Overview, that’s fine, but this catalog is what you need on the bench. Automotive Industry Overview stays online; this PDF stays on your tablet.

Does this catalog include torque specifications for the brake system?

No. This is a parts catalog, not a service manual. It gives part numbers and exploded diagrams. For torque values and repair procedures, use the matching service manual.

How do I know which cylinder part number fits my NR035 AC vs an NR045 AC?

The catalog separates cylinders by model and mast type. For example, Cylinder-Lift (NR 035-045 AC) is on page 6-2, while Cylinder-Lift-Simplex (NR 040/045 AC) is on page 6-42. Cross-reference your truck’s serial number with the model nomenclature on page 2 to match the correct section. If you have an NDR030 AC, the battery lift cylinder is on page 6-43. The alphabetical index lists every cylinder variant with its page number. Start there, verify your mast height code (V for simplex, E for triplex), then order. I’ve seen guys order a triplex cylinder for a simplex mast and wonder why the hoses don’t reach. Don’t be that guy.

Access the Factory Manual and keep it on your tablet next to the service manual. You’ll stop cross-referencing eight different websites and start ordering the right part the first time.
