TM 5-3895-374-24-27. Clean housing flange surfaces on both halves,making sure not to nick or scratch flange face. Placea new bead of gasket eliminator on flange face andspread evenly over entire flange leaving no barespots. Place other housing half into position and tapwith a soft hammer (rawhide not lead hammer) untilhousing bolts can be used or draw housing halvestogether. Torque housing bolts per torque valueslisted below.8. Place output hub seal carrier in position without shimsand install two carrier screws diametrically opposed.Torque each screw to 25 lb.-ins. Rotate the outputhub to roll in the bearings and then torque each screwonce to 50 lb.-ins. Do not retorque screws. Againturn output hub to roll in the bearings. With a feeler ortaper gage. measure the gap between the housingand the carrier, clockwise from and next to eachscrew. To determine the required shim thickness.take the average of the two feeler gage readingsRemove carrier and install the required shims. Note:Total shim thickness per carrier should not includemore than .009" plastic shims and each plastic shimshould be inserted between two metal shims. Place a1/8" diameter bead of Dow Corning RTV732 sealanton the face around the I.D. of the end shim (sealantis to be between reducer housing and shim) andinstall carrier on reducer housing. Torque carrierbolts to value shown in Table 4. Output hub shouldhave an axial end play of .001" to .003".9. Adjust the countershaft bearings using the samemethod as in step 8 above. The axial end play shouldbe .001" to .003".10. Again using the same procedure as in step 8, adjustthe input shaft bearings, except the axial end playshould be .002" to .003".11. Apply sealant to the input shaft cover gasket andinstall input shaft cover in right-hand housing half.Install input and output seals. Extreme care shouldbe used when installing seals to avoid damage dueto contact with sharp edges on the input shaft oroutput hub. The possibility of damage andconsequent oil leakage can be decreased bycovering all sharp edges with tape or paper prior toseal installation. Fill cavity between seal lips withgrease. Seals should be pressed or tapped with asoft hammer evenly into place in the carrier applyingpressure only on the outer edge of the seals. Aslight oil leakage at the seals may be evident duringinitial running in but should disappear unless sealshave been damaged.12. Install bushing back-up plate and snap rings onTaper Bushed reducers.(page 3 - 1285)
