Yanmar B37-P, B37-PR, B37-C, B37-CR 1994 Parts Catalog

If you’ve ever tried to order a replacement hydraulic line for a B37-PR without the factory part number, you know the pain of guessing and getting the wrong piece. This 1994 Yanmar Parts Catalog is the document I’d throw at any junior tech before they touch a crawler backhoe. It covers the B37-P, B37-PR, B37-C, and B37-CR models with European specs. At 148 pages, it’s the last edition published for the European market, superseding earlier versions from 1989 and 1991. The mounted engine is the 3TN84L-RBS — you’ll find that on page 3 along with transport dimensions and engine type. No repair steps here, just the part numbers you need to keep a machine running.

Model Code Breakdown: B37P, B37PR, B37C, B37CR

Page 2 lays out the model code table. Each variant gets a specific code reference. For example, B37C (SW) is cabin configuration for Switzerland, while B37PR (FA) is a canopy model with rubber crawlers for France. The catalog uses abbreviations like UK, AY, and EP to flag which figure applies to which country. That matters when you’re ordering parts for a B37-CR that came from England vs. one from Germany. Check the table on page 2 before you pick a part number.

3 Paint Colors Specified: Saffron Yellow, Cream White, Charcoal Gray

Paint codes are listed on page 1 with Munsell numbers and spray can references. Yanmar Saffron Yellow is 1.0Y7.5/11, paint code 933110-91603. Cream White is 5.0Y9/1, code 981101-09614. Charcoal Gray is N2, code 981101-09516. If you’re doing a repaint or touching up a used machine, these are the factory numbers — not some aftermarket approximation. The catalog also notes that for common specs shared across all destinations, no country indication is given.

Engine Specifications: 3TN84L-RBS

The engine section on page 3 lists a vertical 3-cylinder water-cooled diesel. Transport length is 4830 mm, width 1520 mm, height 2360 mm (canopy models 2385 mm). No torque specs here — this isn’t a repair manual — but knowing exact engine model and dimensions helps when ordering mounts, gaskets, or cooling system parts. The OCR excerpt confirms the engine is the 3TN84L-RBS, so that’s the base for all B37 series machines in this catalog.

Publication History: Three Editions from 1989 to 1994

Page 1 of the preface shows the revision timeline. First edition (Ammann) issued August 1989 (pub no. 000Y00S2950). First edition for England/Australia was April 1990 (000Y00S3020). Second edition (Europe) April 1991 (000Y00S2951). Third and last edition June 1994 (000Y00S2952). That’s the edition you get here. If you have an older machine from the late 80s, this catalog still covers those parts because each revision incorporated design changes up to 1994.

Use the Fig. Number System to Find the Right Part

The preface explains how figure numbers correspond to country models. When multiple figures exist (e.g., Fig. 19 for UK, Fig. 18 for Ammann), the catalog shows which figure applies to which destination. If only one figure fits all countries, it’s marked with a circle. This system eliminates guesswork — you look at your machine’s serial tag, find the country abbreviation, and pick the figure. No more ordering a B37-PR part meant for Switzerland when you need one for the German spec. That’s the value of an OEM parts catalog over a generic cross-reference.

Frequently Asked Questions

Does this manual cover repair procedures or only parts?

Only parts. This is a parts catalog, not a service or repair manual. No torque specs, no removal instructions.

Can I use this for a B37C with cabin?

Yes. Model codes include B37C for cabin variants in Switzerland, Germany, France, and Europe. Check the table on page 2 for your country abbreviation.

What years does this manual cover?

The last edition is 1994, but it supersedes earlier editions from 1989 and 1991. This means parts for machines built up to 1994 are included. However, if your machine is a later model after 1994, this catalog may not reflect any subsequent design changes. The preface states the 1994 edition is the final one for the European standard specification.

Is this the same as the operator’s manual?

No. Operator’s manual is separate.

If you need the exact part number for that hydraulic hose or track roller, do yourself a favor and Access the Factory Manual before ordering a single piece. One wrong number can cost you a week of downtime.
