Furukawa Rock Drill JTH2A-210Z Parts Catalog

Ordering the wrong part for a Furukawa Rock Drill JTH2A-210Z means downtime on a job site. I’ve seen guys grab a seal kit from a generic bin and wonder why the drifter loses pressure after forty hours. This Parts Catalog from Furukawa is the only source for exploded diagrams with genuine part numbers. Skip the aftermarket photocopies – they miss the updates. This catalog runs 428 pages and covers every component except the engine.

428 Pages of OEM Part Data

Page 1 shows the external view of the JTH2A-210Z 2 Boom Wheel Jumbo with part callouts. The table of contents lists seven major sections: External View, Drifter HD210, Guide Shell Unit, and more. Each section breaks down into left and right assemblies – for example, Guide Shell (33L) and Guide Shell (33R) with separate part numbers. The manual’s page 4 states clearly: “When ordering parts, use genuine Furukawa parts” and requires you provide the machine serial number. That rule saves you from getting a center plate that doesn’t fit the boom mount.

Furukawa Rock Drill JTH2A-210Z Parts Catalog: Section Breakdown

Section 2 covers the HD210 hydraulic drifter – the heart of this jumbo. You get the complete parts list from the drifter’s own catalog (HD210Ⅱ-K101) integrated here. Section 3 lists every piece of the guide shell unit: front feeder, hose feeder, carriage, centralizer, sub-centralizer, and hose assemblies. If you’re rebuilding a guide shell, you need the specific ASS’Y numbers for the left and right side – 983301-010012 for left, 983301-010022 for right. The catalog gives you those numbers and the exploded view to match.

How to Order Parts Correctly

Don’t call your supplier with just a description. This catalog expects you to use the five-item order checklist: part number, part name, quantity, machine serial number, and machine name. The OCR excerpt even includes the exact Japanese and English warnings about optional parts not being mounted. I’ve seen a guy order a hose feeder ASS’Y(L) when he needed (R) because he guessed – cost him a week of waiting. The catalog’s page references, like 03-06 for Hose Feeder ASS’Y(L) and 03-07 for (R), eliminate that guesswork.

Drifter HD210 and Guide Shell Unit: Exploded Views

The drifter section uses a separate part number system – 900500-000070 for the hydraulic drifter assembly. The guide shell section has its own numbering: 983301 series. Each exploded diagram is labeled with figure numbers and callout circles. You trace the line from the callout to the part number in the table. For example, the carriage ASS’Y (983301-040051) shows every roller, bolt, and bushing. That level of detail is what separates a factory catalog from a reprint that skips the assembly breakdown.

Why Factory Documentation Matters

Aftermarket parts lists often combine years or omit revision notes. Furukawa prints updates as they happen – the catalog states “parts are subject to change without notice.” You get the latest part numbers as of the publication date. When you have a 2019 machine and a 2022 catalog, you cross-check the serial number range. This catalog is the real deal from FRD Furukawa Rock Drill Co., Ltd. No third-party guesses.

Does this parts catalog include torque specs?

No. This is strictly a parts catalog for ordering components. Torque specs, clearances, and assembly procedures are in the separate service manual for the JTH2A-210Z.

Can I use this to disassemble the drifter?

It provides exploded views and part numbers for ordering, but assembly procedures are not included. The guide shell unit section shows every nut and seal with part numbers – useful for identifying components during disassembly. However, for reassembly torque values and clearances, you need the full service manual. I’ve seen guys try to rebuild a drifter using only the parts catalog and end up with leftover parts because they skipped the manual. Don’t be that guy.

Is this the same as the service manual?

No. The service manual covers procedures, diagnostics, and specs. This parts catalog only gives you part numbers and exploded diagrams. Both are needed for a full overhaul.

What models does it cover?

You need this catalog if you’re ordering parts for a JTH2A-210Z or rebuilding any of its assemblies. The factory illustrations save you from the parts bin lottery. For other equipment, check the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide or the Futura Wear Technology Parts Catalog for wear parts. If you run other heavy machinery, the LANDTRAC TRACTOR Parts Manual Models 410-550 DTC – Section: Numerical Index might also be useful. For broader context on parts numbering standards in heavy equipment, see Automotive Industry Overview.
