Description

Yanmar B15C, B15CR, B15P, B15PR 1997 Parts Catalog

You need a part number. The machine is down. The dealer wants a VIN you can barely read. You flip through a generic aftermarket parts book and the number doesn’t match the bolt in your hand. That waste of time costs money. This Yanmar B15C, B15CR, B15P, B15PR 1997 Parts Catalog is the OEM document from AMMANN YANMAR, printed in May 1997. It covers crawler back-hoe models B15C, B15CR, B15P, and B15PR, with the 3TNE68-NBAB engine. 117 pages. Factory part numbers, not guesses.

Table of Painted Color – Get the Right Paint Code

Section two of the PDF is the TABLE OF PAINTED COLOR. It lists six factory colors with Yanmar part numbers for 16L cans, 4L cans, and spray cans. Example: Yanmar New Permanent Yellow (color code 87) uses spray part 977620-30871. If you are ordering paint for a B15P that spent years in the Texas sun, that table saves you from buying the wrong shade. Page 2 has the full chart. Do not guess flat green vs. deep green – the manual tells you exactly which YANMAR Deep Green (6.36BG2.11/1.76) goes on the frame.

Picturesque Index (1) Main Parts – Parts Layout You Can Read

The PICTURESQUE INDEX (1) MAIN PARTS is a visual parts locator with figure numbers for every assembly: air cleaner, radiator, fuel tank, instrument panel, boom cylinder, bucket cylinder, control valve, wiring, battery, and more. Each figure corresponds to a detailed exploded view later in the catalog. For example, the HYD. OIL PUMP & JOINT is Figure 29; the SWIVEL JOINT is Figure 37. If you are rebuilding a swings cylinder on a B15CR, you flip to Figure 33 and get the factory part callout. No third-party re-draws – this is the actual Yanmar illustrator layout.

Wiring Diagram – Trace the Harness Without Smoke

Page 5 of the catalog includes the full WIRING DIAGRAM. It shows the key switch, relay, horn, cut-off valves for boom and arm cylinders, meter, and fuel tank connections. The diagram is not a generic schematic – it is specific to the B15 series. You need to chase a no-start on a B15P? The wiring diagram tells you exactly which relay feeds the key switch. Do not trust a Chilton drawing for this. Use the factory diagram from the Parts Catalog and you will not backfeed the wrong circuit.

Hydraulic Section – 7 Figure Numbers for Oil Piping and Motors

The PICTURESQUE INDEX (2) HYDRAULIC SECTION covers Figures 29 through 42: oil pump, turning motor, swing cylinder, boom cylinder, blade cylinder, low-high valve, swivel joint, and control valve. Parts are listed with OEM numbers for the B15C, B15CR, B15P, and B15PR. If you need a seal kit for the boom cylinder, the catalog gives you the part number. Without this, you spend an afternoon measuring and hoping. With it, you order once.

Audience – Who Needs This 117-Page OEM Parts Catalog?

This is for the guy who has a Yanmar B15 series crawler back-hoe in his shop and wants to order the correct water pump or hydraulic hose the first time. It is also for the auction buyer who picked up a B15C with missing paint and needs to source parts from a dealer who demands part numbers. If you are a home-garage mechanic rebuilding a torn-down B15CR, the exploded views prevent you from reassembling the swing cylinder backwards. The manual uses imperial units for fastener sizes – that matters when you are grabbing a wrench in a San Antonio shop.

Source Validity – OEM Print vs Aftermarket Reprints

This PDF is scanned from the original AMMANN YANMAR publication, Issue No. 000Y00S3620, dated May 1997. It is not a re-drawn aftermarket copy with missing pages. The TABLE OF PAINTED COLOR is legible, the part numbers match real Yanmar inventory, and the WIRING DIAGRAM is not blurred out. Compare that to a third-party manual where the hydraulic section might be from a different model year – that gets you wrong seals and lost billable hours. If you need a trusted alternative, check the Ammann Yanmar B12 B17 Parts Catalog or the Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs. For a larger machine, see the Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM. The Automotive Industry Overview covers why OEM documentation matters for equipment reliability.

Can I use this parts catalog to rebuild a B15C engine?

This is a parts catalog, not a service manual. It gives you part numbers and exploded views – not torque specs or disassembly steps. For engine rebuild, you need a separate service manual.

Does the wiring diagram include the B15PR CKD variant?

Yes. The catalog covers all four model codes: B15C-AY (172194C), B15CR-AY (172194A), B15P-AY (172194D), and B15PR-AY (172194B). The wiring diagram on page 5 applies to all, but verify your machine’s production date after February 1997. The B15PR CKD has code 1721947 – the wiring harness should match the base B15PR-AY diagram. If you find discrepancies, compare the actual harness to the figure and order the correct pigtail by part number from the catalog.

You have the machine on the lift. The old part is in your hand. The dealer is on hold. Access the Factory Manual now, get the right part number, and move on to the next job.
