Part of the Yanmar Parts Manuals.
Need the exact factory part numbers for your crawler back-hoe? This 103-page Yanmar SV08-1B parts catalog PDF (OEM #0CK50-M00230EN) breaks down every single component for both the SV08-1B and 1A variants. Inside, you get highly detailed exploded views covering the entire hydraulic control valve assembly, swivel joint, and travel motor. Match your physical hardware directly to the diagrams to find complete parts lists with precise OEM numbers, making visual component identification fast and accurate. Verify your undercarriage setup by checking whether your machine takes the 53.5mm Y-specification track roller or the 62mm S-specification roller before placing an order, and confirm your main harness requires a 40A fuse. Stop wasting days waiting for the wrong hardware to arrive. This bookmarked file opens instantly on your tablet, letting you look up numbers right beside the excavator.

Yanmar SV08-1B Common Problems This Manual Covers
Yanmar SV08-1B track derails constantly and the undercarriage wears unevenly on the lower side during operation
Inspect the lower rollers and measure the outer diameter. If the roller measures 53.5mm, check page 33 for the Y specification track roller assembly. Match the part numbers for the bearing, shaft, and seal kits to replace the worn components.
Manual Section: Track Roller(Y Spec.) p. 33Machine has weak starting or no-start behavior with a completely dead electrical system
Locate the main electrical harness and verify the 40A fuse is intact. Review the wiring components on page 29 to identify the exact replacement part numbers for the 40A fuse, 10A fuse, and the 2W resistor to order replacement components.
Manual Section: Wiring p. 29Work lamps fail to illuminate and instrument panel indicators remain completely dark during night operation
Remove the defective bulbs from the work lamp and meter assembly. Consult page 30 to find the specific part numbers for the 12V 27W work lamp bulbs and the smaller 12V 3.4W or 12V 3W indicator bulbs required for replacement.
Manual Section: Equipment p. 30Undercarriage makes loud clunking noises and the lower track tension feels excessively loose
Measure the lower track roller diameter to confirm your machine specification. If your roller measures 62mm, locate the exploded parts view on page 34 to find the correct lower roller assembly, shaft, and seal ring part numbers for the S specification undercarriage.
