Figure 3–3. Measuring Turbine-Driven PTO Backlash
On PTO assemblies that require pressure lubrication, install the lubrication
tube and fittings. The lubricating fluid comes from the line returning to the
transmission from the cooler. Fluid should be directed to the PTO lubrication
circuit after passing through a 0.032 inch (0.81 mm) restriction. (Usually, the
restriction is already located in the PTO.)
