TM 9--2520--215--340002 00--2EQUIPMENT DESCRIPTION AND DATA – CONTINUED0002 00DIFFERENCES BETWEEN MODELS--XT--1410--5A TRANSMISSION – ContinuedLUBRICATION. Low and reverse carrier lube pressure on the main pump from 28 to 40 psi and the lube hasbeen 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 ensurethat the 180--micron filters cannot be installed. A check valve has been added to the pressure side of the outputpump 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 oilto the brake unit continuously. The output reduction unit sprocket carrier uses attaching bolts rather than studsand nuts to secure the sprockets to the carrier and incorporates a keyway. New output shaft seals have alsobeen 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 OILThe use of the proper oil and attention to keeping the oil clean are of major importance. The proper oil levelmust be maintained in the transmission to obtain maximum performance. Check the oil level regularly. Clean filters atspecified intervals. Be very careful that no foreign matter enters the transmission at any time. When changing oradding oil, refer to Oil Specification and Lubrication Order (LO 9--2350--256--12) or TM 9--2350--292--10.
