Sakai SW770HF Parts Catalog – The Only OEM Source for Part Numbers

If you’ve ever had a job stop dead because the part number you ordered didn’t match the machine’s chassis number, you know the cost. That wasted time, the wrong parts sitting on the shelf, the double shipping. I’ve seen it happen more times than I can count. The Sakai SW770HF Parts Catalog is the factory document that kills that guesswork. 105 pages of OEM part numbers, exploded diagrams, and chassis-specific callouts. This is what Sakai technicians use when they order parts for a SW770HF vibrating roller. Not a third-party cross-reference. Not a scanned copy of something that got passed around the shop. The original file from Sakai.

Before you pick up the phone to order a fuel filter or a steering cylinder, you need to know your chassis number. Page 2 of this catalog lays out exactly where to find it stamped on the frame and on the identification plate. That number determines which parts apply to your machine. The catalog lists parts by chassis range – No.10007 or No.10008~. Skip that step and you’re guessing. This document does not let you guess.

Engine System on Page 1 – When the Engine Mounts Need Replacing

The catalog’s first section, Engine System (page 1), covers parts like engine mounts, brackets, pulleys, and belts. Note: the internal engine components (pistons, rings, gaskets) are not in this book. Sakai publishes a separate parts catalog for the ISUZU AI-4JJ1XYLB-02 engine. If you need a head gasket or injector, you will want that separate manual. For everything else – the stuff that bolts the engine to the frame, the exhaust pipe connections, the fan shroud – this section gives you the correct part number and quantity. Each exploded diagram shows key numbers linking to a parts list with descriptions and quantities.

Fuel and Cooling Systems – Two Sections You Need for Routine Service

Section 2 covers the Fuel System, and section 3 is the Fuel System (Filter). I’ve watched guys try to cross-reference a fuel filter element from a generic chart and end up with the wrong thread pitch. This catalog gives you the exact Isuzu filter part number and shows the assembly – banjo bolts, washers, lines. Section 4 is the Cooling System: radiator, fan blades, hoses, coolant reservoir. If you’re swapping a water pump or fixing a hose leak, you get the factory clamp part numbers and hose routing. The torque specs? Not listed in a parts catalog – those are in the service manual. But the part numbers are correct. Use these sections to order exactly what the factory intended.

Does This Catalog Cover the Electrical Equipment?

Yes. The Electrical Equipment sections (7 through 10) break down the panel, fuse and relay box, battery, and lights. Need a fuse box cover? A specific relay? A headlight assembly with the correct SAKAI part number? It’s in there. The panel section shows the dashboard switches, wiring harness connectors, and control units. If you’re chasing an electrical issue, you can use these pages to identify the exact relay or sensor without disassembling everything and matching aftermarket parts. That alone can save hours of diagnosis time. Keep in mind: these are parts catalog illustrations – schematic diagrams for circuits are in the service manual. But for ordering, this is gold.

7 Systems for the Hydraulic and Steering Setup

The steering and hydraulics occupy a big chunk of this catalog. Sections 11 through 24: Control System (Reversing), Steering System (Wheel and Cylinder), Steering Hydraulic System, Hydraulic System (Pump Mounting, Drive 1, Drive 2), and Hydraulic System (Vibrating 1 and 2). Each section includes multiple pages with part numbers for seals, O-rings, hoses, cylinders, and valve assemblies. Section 22 covers the Vibrating Roll itself – eccentric weights, bearings, shaft. If you’re rebuilding a vibratory assembly, you need the factory bearing part number and the shim kit designation. Generic bearings might fit, but the tolerance spec is not something you want to guess on a machine that shakes 2,000 times a minute. Use the OEM numbers from this catalog.

Get the Correct Part Number – Use the Chassis Number Guide

The first few pages of this manual (pages 2-3) explain how to read the chassis number, where to find it, and how the parts application works. Sakai’s system marks each part with a chassis number range in the remarks column – No.10007 or No.10008~. If you ignore that and order from a later serial, you might get a part that doesn’t fit because the supplier changed. The guide also explains abbreviations: LH, RH, Dom., Exp., N/S. That’s not fluff. When you call the parts counter and say “LH steering cylinder”, you need to know which side is left. This catalog defines LH as the left-hand side when viewed from behind the vehicle – consistent with industry standard. Don’t assume.

FAQ

Does this parts catalog include torque specifications or repair procedures?

No. This is a parts catalog, not a service manual. It contains exploded views, part numbers, quantities, and chassis number application data. For torque specs, fluid capacities, and overhaul procedures, you need the Sakai SW770HF Service Manual.

Can I use this catalog to order engine internal parts like pistons or cylinder head gaskets?

The engine internal parts are in a separate engine parts catalog for the ISUZU AI-4JJ1XYLB-02. This catalog covers everything else on the roller – engine mounts, cooling, fuel system, hydraulics, electrical, frame, etc.

How do I find the correct part for my machine if the catalog shows multiple part numbers for one description?

Check the chassis number. The remarks column will show something like “No.10007” or “No.10008~” – that tells you which serial range the part applies to. If your chassis number falls within that range, that’s your part. Always verify before ordering.

Is this the same document a Sakai dealer uses?

Yes. This is the factory parts catalog published by Sakai. The file is identical to what a dealership parts counter would reference. No aftermarket re-draws. No third-party interpretations. 105 pages, original OEM.
