4C-9612  Silicone Sealant 

Note: Inspect the crankshaft rear seal and replace the assembly if there is the slightest sign of damage to the seal.

Note: The following procedure assumes that the crankshaft rear seal is a replacement assembly.


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.

    Typical example

  1. Clean the rear face of the cylinder block (1) and the back plate (6). Inspect the dowels (3) for damage. If the dowels are damaged, use new parts for replacement.

  2. Ensure that the crankshaft flange (4) is clean, dry and free from rough metal edges.

  3. Remove the packaging from the new crankshaft rear seal (5). Ensure that the plastic sleeve (not shown) is squarely installed within the crankshaft rear seal. The plastic sleeve is included in order to protect the lip of the seal as the lip is pushed over the crankshaft flange.

  4. Apply clean engine lubricating oil to the crankshaft flange (4) around the running surface of crankshaft rear seal.

  5. Place the crankshaft rear seal (5) over the crankshaft flange (4) and engage the plastic sleeve onto the crankshaft flange.

  6. Ensure that the plastic sleeve is engaged onto the crankshaft flange (4). Push the crankshaft rear seal (5) evenly and push the crankshaft rear seal smoothly onto the crankshaft flange until the crankshaft rear seal is against the cylinder block. During this process, the plastic sleeve will be forced out of the crankshaft rear seal. Discard the plastic sleeve.

  7. Apply a continuous bead of Tooling (A) to the rear face of the cylinder block around the mating surface of the crankshaft rear seal and around the rear core plug for the camshaft (2).

  8. Align the back plate (6) to the dowels (3) and install the back plate to the cylinder block (1).

  9. Install the setscrews (7) that fasten back plate (6) to the cylinder block (1).

    For the C0.5 and C0.7 engines, tighten the setscrews to a torque of 15 N·m (11 lb ft).

    For the C1.1/3011C and C1.6 engines, tighten the setscrews to a torque of 50 N·m (37 lb ft).

    For the C1.5/3013C, C2.2/3024C and C2.2/3024CT engines, tighten the setscrews to a torque of 25 N·m (19 lb ft).
