This instruction gives the procedure for using the 1U5753 Seal Starter to install the roller frame recoil bearing seal.The interference fit makes the seal difficult to start into the housing without distortion or damage. The 1U5753 Seal Starter allows the seal to be started squarely into the bore without the cocking or rebounding that can occur when using only a hammer. The 1U5753 Seal Starter may be used in the installation of many other large seals and sleeve bearings. The slotted plates adapt to a variety of diameters.Other Tools Required
* FT1965 Driver* 6V3009 Cross Bar (from the 6V3010 Puller Group): Use with the 1U5753 Seal Starter on the D10N, D9L and smaller track-type tractors.* The cross bar from the 8B7548 Puller Assembly: Use with the 1U5753 Seal Starter on the D10 and D11N track-type tractors.Reference: Service Manual and Tool Guide.Installation Procedure
