Yanmar B37-2A 1998 Parts Catalog – 230 Pages OEM Factory Specs

You ever order a part that looked right in the aftermarket drawing but turned out to be the wrong casting? I have. Wasted half a day and a customer’s patience. That’s why when you’re tearing down a Yanmar B37-2A, you don’t guess – you use the Yanmar B37-2A 1998 Parts Catalog. This is the original factory-issued document, not a reprint or a third-party summary. It’s got 230 pages of verified part numbers, paint codes, and exploded diagrams that match Yanmar’s own production line.

Specifications: The Numbers That Matter

Page 2 of this catalog lays out the full machine specs – transport dimensions, bucket capacity (0.05-0.11 m³ standard), max digging force of 2400 kgf, and travel speeds for both rubber and steel crawlers. Need to confirm which undercarriage parts fit your serial number? The table lists machine numbers from M/# 00501 to 51279 and engine numbers E/# 01570 to 14364. That kind of data keeps you from ordering a track shoe that’s 370 mm wide when your variant takes a different width. No guesswork.

Paint Colors and Part Numbers: Why It Matters

You’re painting a boom or replacing a hydraulic tank? The catalog includes a dedicated section – “VEHICLE PAINTED COLOR” – with Yanmar’s official color codes (e.g., Yanmar New Permanent Yellow 5.9Y8.5/11, code 87). That page also lists the color codes for operational parts. If you’re matching a cab or canopy, you get the exact paint number without calling the dealer. Automotive Industry Overview standards apply here – factory paint means fewer callbacks.

Picturesque Index: Finding the Right Part

The catalog uses a “Picturesque Index” broken into three main groups: MAIN PARTS, HYDRAULIC SECTION, and FIGURE 01 through FIGURE 101. That’s 101 figures covering everything from the engine mounting to the blade assembly. Each figure corresponds to a clear exploded view with callout numbers that tie directly to the part number lists. You don’t flip through 230 pages blindly – you go straight to FIGURE 37-48 for the swing mechanism, for example. The index is organized by figure ranges, so even a beginner can find the hydraulic pump section without wasting time.

Understand the Catalog’s Limits

This is a parts catalog, not a service manual. It uses simplified illustrations – no torque specs, no step-by-step removal procedures. Don’t expect to diagnose a hydraulic leak from these pages. What it does give you is the exact Yanmar Genuine Part number for every bolt, seal, and hose. The preface on page 1 warns: “Be careful not to use the simple parts available in the market; otherwise their use in repairing causes such as an early breakage.” That’s real talk.

3 Model Variants Covered

The catalog covers six specification variants of the B37-2A: cabin with front lever (C)FRT, canopy with side lever (P)SID, overseas export versions (C)EX and (P)EX, and more. Each variant has its own part numbers for items like the ROPS frame and control cables. If you’re working on a machine that left the factory between 1994 and 1997, your serial number will fall within the range. Don’t assume all B37-2A parts are interchangeable – cross-check against the table on page 1 that lists model names and columns A through F.

Source Authenticity: OEM vs Aftermarket Parts

Yanmar produced this catalog themselves – not a reprint, not a scanned copy from a third party. The document number is 000Y00K3251, last edition published May 1998. Compare that to the aftermarket catalogs that combine multiple models into one PDF and miss the subtle differences between a canopy and a cabin version. With this OEM file, you get the same diagrams Yanmar dealers use. If you’re looking for related manuals, check the Ammann Yanmar B12 B17 Parts Catalog or the Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs. Another good reference is the Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM.

Can I use this catalog to look up repair procedures?

No. This is a parts catalog, not a service manual.

How do I find the correct part number for my machine?

First, identify your machine’s serial number (range M/# 00501-51279) and specific model variant from the table on page 1 – e.g., B37-2A(C)FRT or B37-2A(P)EX. Then go to the Picturesque Index and locate the figure number covering the system you need (FIGURES 01-12 for engine components, 13-24 for transmission, etc.). Each figure has callouts with part numbers listed on the corresponding page. Match the part number against the Yanmar Genuine Parts list – do not substitute aftermarket “equivalent” parts unless you want early failure. The catalog also includes paint color codes and hydraulic section index to narrow down the exact component.
