White TRIPLEX MULTI LIFT, TRIPLEX TRI-LO, TRIPLEX HIGH FREE, SIMPLEX TWO-RAIL, KNICKERBOCKER 1974 Parts Catalog

If you’re chasing a part number for a 1970s White forklift, you already know the headache. Aftermarket lookup charts are full of cross-references that don’t cross anything except your patience. I’ve stood at a parts counter with a broken mast cylinder and a customer breathing down my neck — a wrong part means another week of downtime. This White TRIPLEX MULTI LIFT, TRIPLEX TRI-LO, TRIPLEX HIGH FREE, SIMPLEX TWO-RAIL, KNICKERBOCKER 1974 Parts Catalog is 66 pages of factory-issued part numbers and exploded views. No guesswork, no third-party reinterpretation. This is the same binder that sat on the dealer’s shelf back when these lifts were new.

TRIPLEX MULTI LIFT Mast Assembly Breakdown

Page 2 of this catalog lays out the triplex mast for the Multi Lift model (2500# capacity, built by Knickerbocker). You get the outer rail assembly (50A1169), center and inner rails, wear pads welded to the rails, and the chain roller setup. Part numbers like 35P1614 for the cylinder assembly and GM120384 for the 1/2″-13 x 2-1/2″ twelve-point bolt are listed with exact quantities. If you’re rebuilding a mast, you need to know that the lock roller shaft (35P667) and the chain anchor turnbuckle assembly are separate items — this catalog keeps them straight. I’ve seen guys order the wrong wear pad because they eyeballed it; the factory calls out 35P653 and 35P1617 depending on position. Don’t guess.

KNICKERBOCKER Cylinder Parts: What You Need

Turn to page 4 for the lift cylinder breakdown of the Multi Lift. The cylinder assembly (35P1614) includes the shell with base, the piston rod (35P1626), and the snap ring (35P1634). There’s a wiper ring for the piston (35P1631) and a head cylinder (35P1627) with two retaining rings. If you’re resealing, note the packing kit (35P1638) — it covers the O-rings and the cap wiper. That kit saves you from sourcing individual seals. The catalog also lists the vent fitting and hose clamp (50A3573). For a 1974 machine, these parts can be tough to find, but with the correct OEM numbers you can cross to NOS or aftermarket equivalents that actually match.

Why OEM Parts Catalogs Beat Generic Lookups

I get asked all the time: “Can’t I just use the serial number and an online decoder?” Sure, if you trust a website that hasn’t seen a forklift in 20 years. Factory parts catalogs like this one were printed from the manufacturer’s database. The illustrations match what you see under the hood. For example, the chain roller (35P656) uses a 3-inch diameter bearing and a specific grease fitting (Alemite 1668). Any generic replacement might not have the same bore or thickness. This catalog eliminates the return trip. Compare that to third-party manuals that list part numbers without confirming fitment. For a shop that charges by the hour, that’s lost money.

Torque Specs and Fastener Details (Page 2 Reference)

This catalog isn’t a service manual, so it doesn’t spell out torque values for every nut. But look at page 2 — it gives you the exact fastener specs: 1/2″-13 x 2-1/2″ twelve-point bolt for the outer rail, 3/8″-24 x 1-3/4″ hex bolt for shaft supports, and 3/4″-16 jam nuts for the anchor rod. If you know the bolt grade (most are Grade 5 or 8 on lifting equipment), you can derive torque from standard charts. The catalog also lists lock washers (50A4239, 5/8″) and plain washers (50A4205, 3/8″). Missing a washer? You’ll get it wrong. Always use the OEM spec for thread pitch and length — aftermarket bolts may have different head heights or thread engagement. I’ve seen a tilt cylinder pin walk out because someone used a cheap bolt; the factory pin (35P1776) is chrome plated and 1.242″ diameter for a reason.

Working with 1970s White Forklifts: Real-World Challenges

These White forklifts — TRIPLEX TRI-LO, TRIPLEX HIGH FREE, and SIMPLEX TWO-RAIL models — use a White MY20, MY25, MY30, MY40C Parts Catalog – OEM Forklift Part Numbers that shares some components but not all. You need this specific 1974 catalog to avoid mixing up parts between the Knickerbocker-built Multi Lift and later White models. For instance, the tilt cylinder pin (part 35P1776) is unique to the Multi Lift; the Tri-Lo uses a different pin length. White MA20B, 25B, 30SB 1979 Parts Catalog – OEM Factory Specs covers later builds, but the 1974 catalog is the only source for early Knickerbocker components. The SIMPLEX TWO-RAIL mast is simpler, but its wear pads and chain setup are documented here too. If you’re also servicing other White models, pair this with White MA20, A25, A30S Parts Catalog – OEM Forklift Part Numbers for complete coverage.

Safety is non-negotiable. This catalog helps you identify the correct NHTSA Safety Guidelines for lifting attachments, but remember that forklift modifications require engineering review. The parts listed here are as-built from the factory — if you swap a chain roller, use the 3-inch diameter bearing with the specified inner race (35P1134) and bearing retaining ring (35P1146). A mismatched roller can cause chain misalignment and sudden load drop. I’ve seen it. Also, when dealing with multi-link mast systems (like the triplex), the geometry is critical; refer to Multi-link Suspension principles to understand load paths, but always use OEM parts for wear items.

FAQ

Does this catalog include torque specs for assembly?

No. It’s a parts catalog, not a service manual. You get fastener sizes and part numbers, but not tightening torque values. Use a separate factory service manual for torque specs.

Can I use this for the TRIPLEX TRI-LO model?

Yes. The catalog covers TRIPLEX TRI-LO, HIGH FREE, SIMPLEX TWO-RAIL, and KNICKERBOCKER variants. Each model has its own exploded views and part numbers — just check the page headers.

The catalog says 66 pages, but the PDF has only 66? Is it complete?

It’s a complete scan of the original 1974 printed catalog. All 66 pages are present, including the fold-out mast breakdown and cylinder assembly sections.

How do I know which part number applies to my lift’s serial number?

Many sections note “Order parts for lift by serial number of mast plus MFH and OAHL.” That means you need the mast serial, model family, and overall height. Without those, some parts may not fit. The catalog gives the part numbers; you provide the serial info to your supplier.
