Engine Assembly (0-02) Section 0 - Engine Disassembly and Assembly - Group 00 M11 Page 0-80 Gear Housing - Installation Caution: Avoid the use of excessive amounts of sealant which could result in blocked oil passages in the engine. Install a new o-ring, Part No. 3883150, into the rear of the gear housing at the oil jumper gallery (1) for the accessory drive support. Be sure to keep sealant from the hole. NOTE: Sealant requires assembly in ten minutes or less. It is best to apply the sealant and then immediately assemble the parts. Apply a bead of silicone sealant, Part No. 3823494, to the groove in the rear of the gear housing.
Completely fill the groove so that approximately 1/16 to 1/8 inch of the bead is raised above the block mounting surface of the gear housing. NOTE: Sealant requires assembly in ten minutes or less. It is best to apply the sealant and then immediately assemble the parts. Apply additional sealant in the area shown in the graphic. Install two guide pins, Part No. 3376488, in the cylinder block. Install the gear housing and 10 capscrews (M10-1.50 x 25) in the inner part of the gear housing. Install five capscrews (M10-1.50 x 50) on the outer surface of the housing. Remove the two guide pins and install the two remaining capscrews (M10-1.50 x 25). Tighten the capscrews in the sequence shown.
Torque Value: Step 1 - 20 [15 ft-lb] 2 - 68 [50 ft-lb] Measure the gear housing protrusion below the oil pan rail. The maximum allowable protrusion is 0.15 mm [0.006 in]. If the protrusion is beyond the allowable limit, remove the housing and check the idler gear dowel pin O.D.
