The seal and wear sleeve are installed as an assembly. Important to remember, if the wear sleeve comes out of the new seal, the new seal is junk.Ī small bead of threadlock 262 is applied to the crank flange and the outer circumferance of the seal is lubed with a 50/50 mix of dish detergent and water. First, removal of the old seal muust be done carefully to avoid damaging the rear crank flange as well as the seal bore - the rear cover is aluminum. The 6.0 has a seal that is installed in the bore in the rear cover (remember, the camshaft and HPOP drive are at the rear of this engine).
#MEDIUM DUTY 5.9 CUMMINS REAR MAIN SEAL INSTALL#
no lubricant necessary to install the 7.3 rear crank seal. The 7.3 has a seal carrier that bolts to the rear of the engine block. Hmmmm.I know you have probabley done more rear mains than I have in a VT.But I have done my share.When we Install a New rear main in a VT-365,We get the complete carrier with the seal installed in it.And I know for a Fact that you do not Use any lubricant.Just push the carrier on evenly and the plastic Installation sleeve will push itself out of the seal bore once it rides over the crank flange.If you are talking about removing the seal from the existing carrier and Installing a new one.The only thing you would do differently is put a Light film of silicone sealant around the outside of the seal before installing it in the carrier.Unless you are describing the style using the wear sleeve Then you would also have to put a few drops of loctite on the edge of the flange first.No dissrespect meant but You have me thinking which is not good /ubbthreads/images/graemlins/eek.gif /ubbthreads/images/graemlins/grin.gif
