Additional Notes
- The Shibaura SD series power steering system holds a capacity of 1.8 liters across all four model variants covered in the 1985-1988 specifications, spanning the SD 3200 through the SD 5000.
- A 1.8-liter capacity in a compact utility tractor power steering circuit is a relatively modest reservoir volume, consistent with the scale of hydraulic assist systems found on machines of this class.
- The SD 3200, SD 3240, SD 3600, and SD 3640 share identical power steering fluid specifications with the larger SD 4500, SD 4540, SD 5000, and SD 5040, indicating no variation in system capacity across the displacement range within the series.
- The fluid check interval is set at 50 hours of operation under normal use conditions, which in hour-metered equipment corresponds to a relatively frequent inspection cycle intended to catch early fluid loss or contamination.
- The fluid change interval is specified at 600 hours under normal use conditions, meaning a full drain and refill of the 1.8-liter system is called for after 600 hours of accumulated operation.
- The ratio between the check interval and the change interval is 12 to 1, meaning the fluid level is inspected twelve times before a full fluid change is due under normal operating conditions.
