PLATE 5169354 - Caterpillar

Preconditions For Trouble-Free Operation
Cleanliness: Ensure that the pipes, pipe connections and hoses as well as all other components are completely clean. Ventilation and venting of the oil reservoir via an air filter. Operating fluid: H-LP fluid acc. to DIN 51525, ATF type A SUFFIX A, HD-SAE motor oils, see SAUER-GETRIEBE-Manual SDFE. Oil level: (The inlet pipe and return flow port must always be below the surface of the oil). No funnel-shaped eddying at the inlet connection pipe. No formation of foam at the return flow pipe. The inlet connection pipe must be substantially above the bottom of the reservoir. A partition plate should be located between the inlet and return flow connection pipes. Filtration: Filtration grade = 10 ? m nominal. Inlet pressure of charge pump: 0.85 bar absolute (-0.15 bar) with a new filter element and at an operating temperature of approx. 50° C.A charge pump inlet pressure less than 0.75 bar absolute (-0.25 bar) is permissible for a short time with a reservoire temperature of less than 50° C on a cold start in order to warm up the system under no load.If frequent cold starts are to be made, the system should be warmed up by a reservoir heater.If the charge pump inlet pressure is less than 0.75 bar absolute (-0.25 bar) on operating temperatures higher than 50°C, the filters must be changed.A charge pump inlet pressure of less than 0.5 bar absloute (-0.5 bar) is not permissible. The filter requires changing or the operating temperature is too low. Venting the pump and motor housing as well as the connection lines and other components.The return flow to the oil reservoir must be free of bubbles. After venting the system, check the fluid level and fill to proper level if necessary. Carry out a leak test on the transmission (inlet line, filter, pipe and hose lines, valves, control elements, pump and motor) giving due consideration to the service life of the transmission, environmental protection and the reduction of oil consumption.Tighten up any leaking joints and other connections while the system is not under pressure. Pressure fluid temperature range: min. = -40° C, max. = +95° C. Viscosity range:max. = 1000 mm2/s (cSt) (for a short time only on a cold start).min. = 7 mm2/s (cSt).Recommended viscosity range: 12-60 mm2/s (cSt). Changing the oil: The oil should be changed after max. 80-100 hours of operation, but at the latest one year after first-time operation.The second oil change should be after max. 500 hours of operation but at the latest one year after the first change of fluid.Thereafter, the oil should be changed every 1000 hours of operation but at least once a year.It is not permissible to mix oil. Renew the inlet filter each time the oil is changed or when the inlet pressure of the charge pump falls below the permissible tolerance. Clean the air filter whenever too much dirt has accumulated. The max. speed is as specified in the SPVE 2 or SMFE 2 catalogue.
