Yale MP, MPB 040 AC A827 1998 Parts Catalog – OEM Factory Specs

Description

Every shop that works on industrial pallet jacks knows the frustration of ordering the wrong part because the number on the old component is worn off or because some third-party catalog used a generic substitute. That is why the Yale MP, MPB 040 AC A827 1998 Parts Catalog belongs on your workbench – not on a PDF pile you will never open. This is the OEM document that the factory used to assemble these units, and it is the only reliable way to match the exact part your customer needs.

Yale MP, MPB 040 AC A827 1998 Parts Catalog: Alphabetical Index Breakdown

Flip to the alphabetical index (page 2 in the PDF) and you will see every major assembly and component listed in plain English – no obscure engineering codes. Need the Solenoid Release Valve? Section 5-4. Looking for the Drive Motor Assembly to DIN 53405? Section 2-14. The index also separates Contactor-Control Panels by region: North American (page 2-2) and European (page 2-6). If you have a PMC control model, there is a dedicated section at 2-18. That level of sorting saves you from flipping through 164 pages blind.

Contactor Control Panel: North American vs European Layout

When a directional contactor fails on a job site, you do not have time to guess which relay configuration matches your truck. Section 2 gives you separate exploded views for the North American resistor panel and the European variant. The parts are not interchangeable in all cases, and the manual lists each part number with its specific callout. Using the wrong contactor can overheat the wiring – something I have seen cause melted harnesses more than once. Get it from the factory drawing first.

3 Critical Sections for Drive and Steering Assembly

Pallet jacks take abuse on the drive axle and steer handle. Section 3 covers the Drive Axle (page 3-14), Drive Tilt and Brake Assembly (page 3-14), and the Steer Handle Assembly for both PMC and resistor models (pages 3-6, 3-10). You also get the Sprocket Assemblies on page 3-17 and the Tire Assembly on page 3-16. If you are replacing a steer handle switch, the manual lists Switch-Handle-Resistor (page 3-3) and Switch-Brake (page 3-7) separately – two different part numbers that some aftermarket catalogs combine into one, which never fits right.

How to Use the Numerical Index for Part Numbers

Section 7 is a numerical index that runs from page 7-1 onward. When you find a part number stamped on a bracket but cannot figure out what assembly it belongs to, cross-reference it here. This is the same method I use in my shop: pull the number, find the page, then order directly from the exploded diagram. It beats calling a dealer and reading off a blurry photo. For example, the Diode-Battery assembly appears in section 5-2, but the numerical index will also list it if you have the diode part number from the supplier bag.

Hydraulic System and Lift Cylinder Parts (Section 5)

The hydraulic pump (page 5-3), lift cylinder assembly (page 5-6), and solenoid release valve (page 5-4) all have their own breakdowns. Note that the manual lists the Lift Pump Motor separately from the Hydraulic Unit – they are two different subassemblies. If you order a complete hydraulic unit expecting it to include the motor, you will be missing components. The parts catalog also includes the Spring-Battery and Battery Diode on page 5-2, small items that often get lost during a battery swap.

Source Authenticity: OEM vs Aftermarket Catalogs

I will say it plain: aftermarket parts catalogs copy the drawings but change the part numbers to cross-reference their own inventory. That introduces errors. This is a factory-issued Parts Catalog from Yale for the MP and MPB 040 AC A827 models, published in 1998 with 164 pages. The document shown here is the original PDF scan, not a retyped copy. Every part number in it matches the Yale parts numbering system used at the time. If you are maintaining a fleet of these pallet jacks, you want this document alongside the service manual.

Frequently Asked Questions

Does this parts catalog cover both the MP and MPB 040 models?

Yes. The model nomenclature on page 1 explains that MP is the base model (Motorized Hand Pallet) and MPB indicates a battery charger built into the power pack. Both are covered in the same 164-page catalog.

Are torque specifications included for assembly?

This is a parts catalog, not a service manual. It does list some fastener callouts on the drawings, but not torque values. You need the Yale service manual for torque specs.

Can I use this to rebuild a hydraulic pump?

You can use the exploded diagram on page 5-3 to identify every seal and piston part number, but the rebuild procedure is not described. Use it for ordering parts before you start the tear-down so you have everything on hand.

Is the PDF searchable or is it a scanned image?

It is a scanned image of the original printed catalog, so you will need to visually read the text. The alphabetical and numerical indexes make navigation straightforward.

Every minute you spend chasing the wrong part number costs labor and delays. The factory-issued Yale MP, MPB 040 AC A827 1998 Parts Catalog gives you the exact drawings and part numbers that Yale used on the production line. Access the Factory Manual and keep it on the tablet next to your toolbox – you will pull it out on every job that involves a pallet jack drive axle or hydraulic system.
