White Materials Handling Triplex High Free Lift Upright, Duplex High Free Lift Upright, Simplex Low Free Lift Upright, Simple Upright Parts Catalog

You need the right part number before you buy a seal kit or a lift cylinder. Guessing means ordering wrong parts, downtime, and freight charges both ways. This 67-page White Materials Handling Triplex High Free Lift Upright, Duplex High Free Lift Upright, Simplex Low Free Lift Upright, Simple Upright Parts Catalog gives you factory illustrations and exact OEM part numbers. No aftermarket re-draws. No third-party consolidations. This is the same book the dealer parts counter used.

If you are rebuilding a mast on a White Materials Handling forklift, you need to know which cylinder revision fits your serial number. The catalog breaks down every upright type into capacity ranges and includes variable parts charts for production changes. Page A-16 through A-18 cover Triplex Variable Parts Charts – those pages alone save you from ordering a part that was superseded in 1979.

Let me walk you through what is actually inside this book. The table of contents is laid out by upright style and capacity, so you do not flip through 67 pages looking for a carriage bolt.

Triplex, Duplex, Simplex, Simple – 4 Upright Types Covered

The catalog starts with Triplex Common Parts split into three capacity groups: 2000# to 3000#, 3000# to 5000#, and 5500# to 6000#. Each group gets its own exploded diagram and parts list. Then you get Triplex Carriages (pages A-11, A-12) and Triplex Lift Cylinder assemblies (pages A-13 to A-15). After the Triplex section, the Duplex, Simplex & Simple Common Parts section begins on page B-2, covering capacities from 2000# all the way up to 12,000#. Separate sections cover Duplex, Simplex, and Simple carriages (B-10 through B-16) and their respective lift cylinders (C-2 through C-8).

If you run a shop that sees White forklifts from 2000 to 12,000 lb capacity, this single catalog covers your upright parts needs. The Simple Upright Chart on page D-11 gives you the mast dimensions for the basic low-free-lift models. A Load Alert section on page D-13 covers the MA35-60 with Triplex, Duplex, and Simplex uprights – that is a safety bulletin you want on the bench.

Parts Breakdown by Capacity Range

Capacity matters because White used different rail sections and cylinder stroke lengths. The catalog groups parts by rated load, not by model number. For example, the Triplex Common Parts for 2000# to 3000# Uprights (page A-3, A-4) use different lift chains and wear strips than the 3000# to 5000# group. If you order parts for a 3000# truck using a 5000# diagram, you get oversized bearings. The catalog eliminates that risk.

Variable parts charts (pages A-16 to A-18) list every production variation with the corresponding part number and effective serial number range. You can verify exactly which part your upright assembly left the factory with. Need the Duplex Upright Chart for a 5500# to 6000# truck? Page D-4. The Simplex Upright Chart for 10,000# to 12,000#? Page D-10. Every chart references the original White part numbers, not aftermarket cross-references that might be wrong.

Cylinder Diagrams and Part Numbers

The lift cylinder sections run from page C-2 through C-8. You get separate diagrams for Duplex Lift Cylinder (2000# to 6000# on pages C-2, C-3; 6000# to 8000# on page C-4), Simplex & Simple Lift Cylinder (2000# to 6000# on pages C-5, C-6; 6000# to 12,000# on pages C-7, C-8). Each diagram shows the rod seal, piston seal, wiper, and backup rings with dimension callouts. If you are rebuilding a cylinder, you find the stack height and snap ring groove location. No need to disassemble and measure – the factory already did that. Compare your old part number against the catalog’s numerical index (pages E-2 through E-17) to confirm the revision.

Does This Catalog Cover Your Specific Model?

The catalog covers I-beam uprights on White Materials Handling trucks from 2000 to 12,000 lb capacity. It includes four upright styles: Triplex High Free Lift Upright, Duplex High Free Lift Upright, Simplex Low Free Lift Upright, and Simple Upright. Model references include MSB, MA, WC, MY, and others. The last page (D-12) lists mounting parts for MY60-70A Duplex and Simplex uprights. If your truck’s upright matches one of those configurations, this catalog has the parts data. If you are working on a different brand, look at our other OEM manuals: White Materials Handling MSB-20 to MSB-35 1967 Repair Manual, Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide, and Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs.

Factory Specs vs Aftermarket – Why It Matters

Aftermarket parts catalogs often combine multiple manufacturers into one generic drawing. That works for a standard bolt, but not for a lift cylinder with a specific gland design. White’s engineers designed the I-beam uprights with proprietary rail profiles and wear pad angles. The Automotive Industry Overview shows why OEM documentation matters for load-bearing components. If you use a wrong part number on a Triplex High Free Lift Upright, the free-lift mechanism could bind or drop the load. The catalog’s Load Alert section (page D-13) specifically warns about modifications. That is the kind of detail aftermarket books leave out. This is a direct scan of the original printed catalog – no re-drawing, no re-typing. You get the exact parts list White Materials Handling published.

FAQ

Can I use this catalog to order parts for a 1978 White MSB-20 with a Duplex upright?

Yes. The Duplex sections cover 2000# to 8000# capacity with specific pages for different capacity ranges. Check the Duplex Upright Charts starting on page D-2 to find the correct chart for your truck’s rated load. Use the Numerical Index (pages E-2 through E-17) to locate any part number.

Does this catalog include torque specs for cylinder bolts?

This is a parts catalog, not a service manual. Torque specs are not included. For assembly instructions, get the corresponding repair manual.
