TRANSMISSION OIL

TM 9--2520--215--34 0002 00--2 EQUIPMENT DESCRIPTION AND DATA – CONTINUED 0002 00 DIFFERENCES BETWEEN MODELS--XT--1410--5A TRANSMISSION – Continued LUBRICATION. Low and reverse carrier lube pressure on the main pump from 28 to 40 psi and the lube has been restricted to the intermediate carrier, high clutch and turbine shaft. To improve oil quality, one set of trans- mission filters has been changed to use 25--micron filters and the converter housing has been modified to ensure that the 180--micron filters cannot be installed. A check valve has been added to the pressure side of the output pump to only allow oil flow in the forward direction. This will prevent back flow during reverse operation. OUTPUT REDUCTION UNITS. The output reduction unit brake lube/cooling has been improved by supplying oil to the brake unit continuously. The output reduction unit sprocket carrier uses attaching bolts rather than studs and nuts to secure the sprockets to the carrier and incorporates a keyway. New output shaft seals have also been installed to prevent damage to the seal during installation of lifting eye. LUBRICATING OIL. Lubricating oil used in the XT--1410--5A transmission is CAT TDTO (CAT 10) oil. TRANSMISSION OIL The use of the proper oil and attention to keeping the oil clean are of major importance. The proper oil level must be maintained in the transmission to obtain maximum performance. Check the oil level regularly. Clean filters at specified intervals. Be very careful that no foreign matter enters the transmission at any time. When changing or adding oil, refer to Oil Specification and Lubrication Order (LO 9--2350--256--12) or TM 9--2350--292--10.
