Yale 1700, 1900 Parts Catalog – Factory OEM Parts Manual

You need a part for a Yale 1700 or 1900 loader. You order it from a catalog number that looks close. Three weeks later the box shows up and the bolt pattern is wrong. The bushing is a sixteenth off. Now you’re down another day, the machine is still sitting, and the customer is watching his hourly rate bleed out. That’s exactly why this Yale 1700, 1900 Parts Catalog exists. It’s the original OEM document from Eaton Construction Equipment Division, printed in 1975, and it’s the only way to land the right part the first time. No calling around, no cross-referencing three different websites. Just the factory drawing and the correct part number.

Accelerator Pedal and Linkage: GM vs PO Differences

This manual breaks out every system by engine type. The accelerator pedal and linkage has two separate entries: one for GM engines (pages 32,33) and one for PO (Perkins? – page 31). If you’re working on a loader with a GM power plant, you don’t want to order a part designed for the PO linkage. The catalog lists each part with its illustration and number side by side. You can look at the drawing and see exactly which bracket, which rod, which spring belongs. That’s the difference between a Friday afternoon job and a Monday morning reorder.

Axle Assemblies: Model 1700 vs 1900 – What’s Different?

Front axle assemblies for the 1700 start on page 124. The 1900 front axle starts on page 134. Rear axles follow the same pattern. The differential groups are separate sections, with their own page ranges: 1700 front differential runs pages 130 through 131A, 1900 front differential runs pages 144,145. If you’re trying to swap a ring and pinion from a 1700 into a 1900, you will find out fast that the part numbers are not the same. The catalog shows you the exact exploded view of each differential so you can match the serial number on your machine to the correct illustration. Yale 1700 1900 Loaders Parts Manual – Section: Floor Plates & Seat Support walks you through the cab and floorplate structure, which is a separate section on page 9.

Hydraulic Control Valve Assemblies: 2 Spool vs 3 Spool

The main hydraulic control valve is listed in two variants: 2 spool (pages 60-62) and 3 spool (pages 62B-62D). If your machine has a third spool for a grapple or a quick-attach, you need the 3-spool section. The manual also covers the bucket cylinder (page 56), lift cylinder (page 57), and steering cylinder (page 66). Each component is shown with its own exploded diagram and a parts list that includes the quantity per machine. Note the “A.R.” (As Required) notation for items like seals – you order what you need, not a fixed number.

Electrical System and Battery Wiring – Pages 46-48

Battery and wiring is covered on pages 46 through 48. The headlights are on pages 44,45. The gauges and instrument panel run pages 42,43. This is a parts catalog, not a wiring diagram manual, but it does show every connector, switch, and wire harness with a part number. If you’re rebuilding a 1975 loader that has been hacked together with 14-gauge automotive wire, you can use these pages to source the factory harness and get the charging system back to spec. Yale 1700, 1900 1975 Parts Catalog – Factory Specs for Loader gives you the same exploded view for the entire machine, including the torque converter assembly (pages 70-72) and the transmission control valve (pages 96,97).

Transmission and Clutch Groups – What You Need to Know

The forward, reverse, 2nd and 3rd clutch group is on pages 94,94A. The low clutch group is on page 95. These are separate assemblies, and the part numbers are not interchangeable. The clutch cut-out switch and system are on pages 119 and 101. The torque converter assembly runs from page 70 through 72. If you’re rebuilding a transmission, you need to order the correct clutch pack, piston, and seals from the exact page that matches your machine’s serial number range. The manual includes a serial number entry page (page 2) where you’re supposed to write your machine’s serial number – that’s the only way to guarantee you’re looking at the right revision.

3 Reasons to Use the OEM Parts Catalog Instead of Aftermarket

Aftermarket parts catalogs for old loaders often combine multiple model years into one drawing, and the part numbers are either wrong or superseded without notice. This document is the original 1975 print from Eaton (O&K). It was the last word for the dealer parts counter. The abbreviation “N.S.S.” (Not Serviced Separately) tells you when you have to buy an assembly because the component is only sold as part of a larger unit. The abbreviation “N.I.” (Not Illustrated) warns you that a part exists on the machine but is not shown in the drawing – you need to order by description, not by picture. Yale 1700, 1900 Parts Catalog – Factory Parts Manual for Loaders is the same document you’d pull off the shelf at a dealer in 1975. No reprints, no scanned copies with missing pages. This is the genuine 194-page OEM catalog.

How to Use the Index to Find Any Part Fast

The index at the front of the manual lists every system alphabetically, from “Accelerator Pedal and Linkage” to “Hydraulic Control Valve Levers, Main (2 Spool).” You find the system, you turn to the page listed, and you see the exploded illustration with callout numbers. The parts list below each drawing gives the part number, part name, and quantity. If you need a bucket assembly, it’s on pages 14 and 15. The bucket indicator is on page 20. The automatic bucket leveler is on page 155. The automatic hoist cut-out is on page 156. Every system is mapped out the same way. That’s the value of a factory document – you don’t guess, you look.

FAQ – Yale 1700, 1900 Parts Catalog

Does this manual cover both the 1700 and 1900 models?

Yes.

How do I find the correct part number if my machine has a different engine than the one shown in the illustrations?

The manual separates GM and PO (likely Perkins) engine components into distinct sections. For example, the air cleaner is shown on pages 36,37 for GM and pages 38,39 for PO. The engine and related parts section starts on page 22 for GM and page 26 for PO. You must match your engine type to the correct section. The manual also includes a page at the front (page 2) where you record your machine serial number, engine model, transmission part number, and axle part numbers. If you fill that in, you can cross-reference the index to the correct pages. The index is alphabetical by system, so for “Fuel Tank and Lines (GM)” you go to page 34; for “Fuel Tank and Lines (PO)” you go to page 35. Without this manual, you’re ordering blind. With it, you have the exact part number from the factory drawing. Automotive Industry Overview may give you context on why OEM documentation matters, but this manual is the specific tool you need.
