Where does the fluid go? One source of discrepancy.
If the hydraulic fluid is between the marks on the dipstick before I de-mount the backhoe, the dipstick will be dry after the BH is off. I knew I lost an ounce or two disconnecting the hoses, but the first time I was consternated. Then I realized that an extended cylinder holds more fluid than a retracted cylinder owing to the displacement of the rod. When de-mounted the stabilizer and boom cylinders are extended versus their position in the mounted, travel position. It's possible that the manual isn't accounting for all the factors, such as oil in the filter or residual oil that didn't fully drain. I’ve seen similar discrepancies in other models too. If you're trying to understand how this might relate to maintenance practices or technical standards, checking out some well-researched materials could be helpful. For instance, the
best literature review writing services offer great insights into research methodologies that might deepen your understanding of such technical details. But for now, I'd suggest keeping an eye on the oil level and not overfilling, as that can lead to other issues.
