Toyota 6BNCU15, 6BNCU17, 6BNCU18, 6BNCU19, 6BNCU20 1999 Parts Catalog

If you’re ordering parts for a Toyota electric stand-up lift truck from the 6BNCU line, you don’t get second chances on part numbers. One wrong digit and you’re waiting a week for the wrong seal kit. This 1999 Parts Catalog covers the 6BNCU15, 6BNCU17, 6BNCU18, 6BNCU19, and 6BNCU20 models shipped after June 1, 1999. It’s the factory document, not an aftermarket reprint. 151 pages of exploded diagrams, Toyota part numbers, and quantities as each.

I’ve torqued enough head bolts to know that using aftermarket parts lists is a gamble you don’t take on customer equipment. This catalog gives you the exact Toyota part number for every component from the battery gates to the traction motor cooling fans. That’s the difference between a job that goes together and one that sits on the hoist because the lift cylinder seal was wrong.

7 Major Systems Covered

The table of contents breaks this catalog into nine major groups: Frame, Drive, Brakes, Steering, Operator Controls, Lift & Auxiliary, Elevating, Electrical, and Options. Each group is subdivided by subassembly. For example, under Elevating you’ll find V-Mast, FV-Mast, FSV-Mast, QFV-Mast, and standard carriages. Each mast type includes separate sections for lift hydraulics and internal reeving. That level of granularity means you won’t be flipping through generic pages wondering if the part number for a 6BNCU20 is the same as a 6BNCU18.

Drive group covers the drive unit (2.01.01 and 2.01.03), drive wheel and tire assembly (2.02.01), and encoder assembly (2.03.01). Brakes gets its own group – brake actuator assembly (3.01.02), brake pedal assembly (3.02.02), and disc brake unit (3.03.01). Steering includes the tiller/encoder assembly (4.04.01) and steer fork assembly (4.02.01). Each of these sections has a corresponding exploded view with callouts that match the Toyota part number listed in the table.

Mast Assembly: Which Section Covers Your Lift?

This manual has a dedicated Mast Serial Number Identification section (7.00.01) before the mast assemblies. That matters because Toyota changed internal reeving configurations across production runs. You’ll need the serial number off the plate in the operator compartment – the manual tells you exactly where to find it. Then you go to V-Mast (7.01.01), FV-Mast (7.02.01), FSV-Mast (7.03.01), or QFV-Mast (7.04.01). Each one lists lift hydraulics and internal reeving separately. If your truck has a side-shift carriage, there’s a section for integral sideshift (7.08.01) and hang-on sideshift (7.08.02). Don’t guess – use the serial number.

Check the Serial Number Plate First

Before you order anything, locate the model and serial number plate. The manual states it’s inside the operator compartment. The model number example on page 2 tells you how to decode it. All quantities are listed as “each” unless otherwise noted. Items marked with a checkmark in the COMMENTS column are recommended spare parts – Toyota dealers are supposed to stock those. If you see that checkmark, order two. Otherwise you’ll be waiting on a part that should have been on the shelf.

A common mistake with these stand-up trucks is ordering the wrong control handle mechanism (5.03.01) or dual-axis assembly (5.05.01). The catalog includes both the standard and replacement options (5.04.01). If you’re rebuilding a 6BNCU19 that’s been modified, the Multi Lever assembly (5.06.01) might be different from the base 6BNCU15. The exploded views show the differences.

Electrical Schematics: Factory Pin Designations

Chapter 8 covers the electrical system: chassis electrical (8.01.02), control harness pin designations (8.02.02), contactor and fuse panel (8.03.02), resistor assembly (8.04.02), control electronics (8.06.01), and electrical interconnect (8.07.01). The pin designations are critical if you’re replacing a harness or diagnosing an intermittent fault. Aftermarket pinout charts often swap wire colors. This catalog gives you the Toyota factory pinout – no guessing.

For the lift hydraulics, the chassis hydraulic assembly (6.01.03) and auxiliary chassis hydraulics (6.02.01) include the manifold (6.03.02) and a full hydraulic schematic (6.04.02). That schematic is worth the price of the catalog alone when you’re tracing a leaky fitting.

Options Chapter 9 – Work Lights, Impact Sensor, Brush Wear Indicators

Options are often the first thing aftermarket catalogs skip. This manual devotes a full chapter to them: mast-mounted work lights (9.01.01), overhead guard work lights (9.02.01), flashing lights (9.03.01), brake/tail light (9.02.01 again – note the bookmark is duplicated, but the page numbers differ), operator compartment fan (9.04.01), impact sensor (9.05.01), brush wear indicators (9.06.01), and traction motor cooling fans (9.07.01 and 9.07.02). If your truck came with any of these from the factory, the part numbers are here.

For official Toyota technical bulletins and owner manuals, check Automotive Industry Overview and Automotive Industry Overview. That site gives you access to current service campaigns, but it won’t give you the 1999 parts catalog – that’s what we have here.

One last thing: this is a parts catalog, not a service manual. It doesn’t include torque specifications, repair procedures, or safety operating instructions. You need the corresponding service manual for those. But when you’re ordering parts, guessing the part number costs you time and money. This 151-page catalog eliminates that guesswork.

Does this catalog cover the 6BNCU23, 6BNCU25, 6BNCU28, and 6BNCU30 models?

Yes. The second page explicitly lists those models as included, but the primary focus is on 6BNCU15 through 6BNCU20. It also covers the 6BVNCU13. All built after 06/01/99.

How do I find the correct part number for a mast assembly?

Start with section 7.00.01 – Mast Serial Number Identification. Your serial number tells you which mast variant you have. Then go to the appropriate assembly section (V-Mast, FV-Mast, etc.) and find the exploded view. The part numbers are listed in the table alongside each callout.

Are torque specs included in this catalog?

No. This is a parts catalog. You need the separate service manual for torque values, adjustment specs, and repair procedures.

Can I use this to rebuild the drive unit?

You can order all the seals, bearings, and components using the part numbers from sections 2.01.01 and 2.01.03. But you’ll need the service manual for disassembly and reassembly instructions. The catalog only gives you the part numbers and quantities.

Don’t waste a week waiting for the wrong part. Access the Factory Manual now and start ordering with confidence that you have the exact Toyota part number in hand.
