Kyokuto Kaihatsu PH14-52 Parts Catalog

If you’re ordering parts for a Kyokuto Kaihatsu PH14-52 concrete pump and you don’t have the factory parts catalog open on your bench, you’re working blind. I’ve seen too many guys swap a seal with a p/n from a third-party list only to have it fail at 2000 PSI. This isn’t a service manual – it’s 156 pages of exploded-view parts breakdowns from Kyokuto Kaihatsu. Every bolt, every bushing, every hose section is listed with its factory part number. No translation needed – the diagrams are universal. The catalog number is PA-PHO2060M, clearly marked on the cover. You get the same document the dealerships use.

Unit Assembly (Section 2-1): Where the Pump Starts

The core of the PH14-52 is the unit assembly – that’s section 2-1 in the catalog, spanning pages 6 through 9. You’ll find all the main pump components, including the squeeze tube mechanism and the drive assembly. Each item is numbered, cross-referenced to a parts list. Need the hydraulic motor for the planetary gear? Look at section 3-3, the oil motor assembly. The catalog won’t tell you how to rebuild it, but it will give you the exact part number to order. Pair this with a factory service manual and you’ve got a complete solution.

5B Pipe Boom Assembly – Get the Right Sections

Section 2-2 covers the 5B pipe boom assembly. If you’re replacing a bent boom section or adding a new one, you need these pages. The boom is a multi-stage fold – get one wrong part and the whole geometry shifts. The catalog lists each boom piece, the pins, the retaining hardware. Check the parts list for quantities: often you need multiple of the same bushing or spacer. Don’t assume you can reuse old hardware – order new from the factory numbers provided. The Automotive Industry Overview on Wikipedia gives context on why OEM parts matter for safety-critical equipment like concrete pumps.

Hydraulic Piping Layouts: Boom and Chassis

Sections 2-11 and 2-12 cover the hydraulic piping for the chassis and boom. These are not generic diagrams – they’re specific to the PH14-52. You’ll see every fitting, every hose, every clamp. If you have a leak in the boom swing circuit, the drawing shows exactly which hose assembly connects where. The parts list includes the hose part number, length, and fitting type. For the concrete piping, sections 2-13 and 2-14 show boom and chassis piping separately. That’s critical when ordering replacement pipes – the routing differs.

Planetary Gear and Roller Assemblies (Section 3)

Section 3 breaks down the roller assembly (3-1), planetary gear assembly (3-2), and oil motor assembly (3-3). These are high-wear components. The planetary gear section lists the sun gear, planet gears, carrier, and bearings. Don’t try to match aftermarket bearings by dimensions alone – the catalog gives you the factory part number. Same for the roller assembly: the rollers and their support brackets are unique to this model. Speaking of aftermarket, I’ve had more problems with non-OEM wiring diagrams than any other part. That’s why this catalog is factory-original, not a reprint from a third party. If you want another model, check the Kyokuto Kaihatsu PY21-50 Parts Catalog – 240 Pages of Factory Specs or the Kyokuto PH11-50 1987 Parts Catalog for older units. Also the Kyokuto PY120-36 Parts Catalog covers a different chassis.

Control Wire, Hopper, and Oil Cylinder – Getting the Numbers Right

The catalog doesn’t stop at major assemblies. Section 5 covers the control wire assembly – those cables that run from the remote to the boom controls. Each cable end, each clevis, each spring is listed. The hopper assembly (section 4) includes the agitator motor (4-1) and all mounting hardware. The oil cylinder assembly (section 5) shows the hydraulic cylinders used for the boom folds. Every seal kit part number is in there – you just need to find the cylinder section and look for the seal kit reference. The Automotive Industry Overview page on Wikipedia explains the standards for hydraulic components, but that’s background – the real data is in this catalog.

Source Authenticity: Why OEM Beats Aftermarket Every Time

This is a genuine Kyokuto Kaihatsu parts catalog – not a scanned copy of a copy, not a compilation from third-party databases. The OCR excerpt from page 1 shows the official catalog number PA-PHO2060M, the company name (極東開発工業株式会社), and their service partner network printed on pages 156-158. Aftermarket catalogs often misnumber parts, omit supersession updates, or use generic images. With this factory document, you get the exact revisions Kyokuto released. The preface warns that parts may change without notice due to chassis modifications – an aftermarket reprint won’t carry those updates. For a machine that pushes concrete at high pressure, you bet part accuracy matters.

FAQ – Parts Catalog Questions

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Use the factory service manual for torque values.

How do I decode the part numbers in the catalog?

The part number format is explained in the preface: catalog number PA-PHO2060M, then main item number, symbol, part number, part name and size, and quantity per machine. For example, on page 3, item 11 shows part number PC19-E7009B – a hole cover with quantity 6. You must include all this when ordering. The catalog uses Japanese text for names, but the numbers and diagrams are straightforward. If you can’t read Japanese, you can still identify parts by matching the exploded view and the part number list. The key is to cross-reference the section number (e.g., 2-1 for unit assembly) and the index number within that section. It’s standard OEM catalog practice.

Can I use this catalog to rebuild the entire pump?

Yes, if you have the service manual alongside. The catalog shows every sub-assembly – from the unit assembly (page 6-9) to the control wire assembly (page 76-77). You can identify every part needed for a full rebuild. But you need the service manual for clearances and hydraulic specs.

What if my machine has serial number variations?

Kyokuto Kaihatsu warns that parts may change without notice due to chassis spec modifications. Always verify your chassis model and use the latest catalog revision. The dealer network is listed on pages 156-158. If in doubt, call a factory-authorized dealer with your chassis serial number.

Working on a PH14-52 without the OEM parts catalog is like trying to navigate San Antonio without a map – you’ll eventually find the highway, but you’ll waste time and money. Access the Factory Manual now from AutoRepairManuals and keep a copy on your tablet or printed out. You won’t second-guess a part number again.
