Kubota D1402-BB, BBS-EC-1 1988 Parts Catalog

You’ve got a D1402-BB or BBS-EC-1 Kubota diesel on the bench and need to order parts. Pull up some generic online parts diagram and half the numbers don’t match. That’s because aftermarket sellers copy old scans and leave out the interchange tables. This 1988 factory parts catalog from Kubota gives you the original part numbers, exploded views, and the I.C. column that tells you whether a new part can replace an old one or not. Kubota D1402-BB, BBS-EC-1 1988 Parts Catalog is the real deal – 77 pages of factory-sourced data.

Cylinder Head and Valve Train: Factory Parts Breakdown

Section 3 covers the Cylinder Head – culasse / Zylinderkopf. You get the exact code numbers for valves, guides, seats, and springs. Section 8 breaks down the Valve, Rocker Arm assembly – soupapes et culbuteurs. Each part has a reference number tied to the exploded drawing. If you need a valve stem seal or a rocker shaft, you don’t guess – you match the number on page 2’s index. The manual uses three languages (English, French, German) so you can cross-reference if working with imported parts.

Does This Catalog Cover the Injection Pump and Nozzles?

Yes. Sections 12 through 15 cover Nozzle, Injector and Tubing, Fuel Filter, and Injection Pump. Section 25 even gives a separate breakdown of the injection pump with section parts – useful if you’re splitting the pump from the engine. Section 13 includes nozzle holders with part numbers for both D1402-BB and BBS-EC-1 variants. The I.C. column in the parts list tells you if a redesigned injector fits your serial number range.

77 Pages of OEM Part Numbers – Why Aftermarket Copies Fail

This catalog has 77 pages. Aftermarket versions usually strip out the interchangeability notes and the numerical index. Without the index, you can’t look up a code number quickly. The original also includes the S.No. column that indicates which serial numbers accept certain parts. That matters when you have an older engine and need to order a flywheel (Section 11) or a camshaft (Section 10). Aftermarket copies often omit that column, leading to wrong orders. This is the genuine Kubota print from November 1988.

Interchangeability Codes: Decoding the I.C. Column

Page 2 explains the I.C. symbols. A new part that can replace an old part is marked with one symbol; if they’re not interchangeable, you get a different mark. The catalog even shows two model variants: A for D1402-BB-EC-1 and R for D1402-BBS-EC-1. If you ignore the I.C. codes, you might order a part that doesn’t fit your engine’s serial number. For example, the crankshaft main bearing case (Section 5) has different codes depending on the build date. The factory manual spells it out.

Ordering Parts for the D1402-BB and BBS-EC-1

Use the numerical index at the back to find any code number. The catalog lists attached parts for air cleaner, radiator, and dynamo (Section 20 and 28). If you need a starter, Section 27 gives you the section parts breakdown. The front of the book shows how each group is organized – title number, components, point, reference number, serial number, interchangeability, and remarks. Follow that structure and you won’t order a water pump for the wrong side. For another Kubota diesel parts breakdown, check the Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown. Or if you need a larger tractor engine, see Kubota YU4210, YW0981 Parts Catalog – 274-Page OEM Parts Breakdown. Mower deck parts? The Kubota RCK60-27B Parts Catalog – 27-Page OEM Breakdown covers it.

The automotive industry standard for parts identification relies on factory catalogs like this one (Automotive Industry Overview). OEM documentation eliminates guesswork. Another note: this catalog is for parts ordering only, not service procedures – get the service manual for torque specs and repair steps (Automotive Industry Overview).

FAQ

Is this catalog in English?

The header and part descriptions are in English, French, and German. The part numbers are universal.

Can I use this to rebuild the engine?

No. This is a parts catalog, not a service manual. Use the separate service manual for torque specs and repair steps. This catalog is for ordering correct parts. If you need assembly torque values or clearance specs, you’re looking at the wrong document.

What does the I.C. column mean?

Interchangeability column tells you if a redesigned part can replace the old one. The instructions on page 2 explain symbols: a new part can replace an old part, but not always vice versa. If you ignore the I.C. codes, you might order a part that doesn’t fit your serial number range. The column also distinguishes between model A (D1402-BB-EC-1) and model R (D1402-BBS-EC-1).
