Yanmar B05 Parts Catalog

Trace the blown circuit on the wiring diagram to confirm which line is affected. The machine runs a 10A fuse (page 33); match that rating to the correct fuse part number in the parts number list. Confirm your model variant on page 1 before ordering, as the L70ADEB designation may reference a different part number than the B05 family.

Open the hydraulic parts diagram and match each hose assembly to its assigned callout number in the exploded view. Cross-reference those callout numbers in the parts number list. The B05 has a max ground-level reach of 2370 mm (page 2), meaning boom and arm hose lengths are model-specific; verify your serial range on page 1 before placing the order.

Locate the sprocket assembly in the drivetrain parts diagram and note the callout number. Confirm tooth count at page 37 before ordering; the replacement must match the original 11-tooth configuration. Cross-reference the callout number in the parts number list, then check your model variant on page 1, as undercarriage configurations differ between the B05 and L70ADEB.

Pull up the wiring diagram and trace the joystick circuit to identify the connector designation. Confirm the fuse protecting that circuit is 10A at page 33 so the replacement connector is specified for the correct load. Match the connector designation to the parts number list, then cross-reference physical mounting hardware in the cab interior diagram.

Open the boom and attachment parts diagram and identify each pin and bushing by its individual callout number; the exploded view separates them even when they share an assembly group. Cross-reference callout numbers in the parts number list. The standard bucket is rated at 0.011 m³ (page 2) on the B05 base model; verify your serial range on page 1 before ordering to ensure pin dimensions match.

Match your serial number against the model and effective machine number columns on page 3 to identify the correct Munsell color code for each body section. Locate the corresponding paint part number on page 4. At 2400 mm long and 690 mm wide (page 2), this machine has substantial painted surface area; confirm that separate part numbers are ordered for each color zone shown on page 4.
