Perkins 1106D - Crankshaft Rear Seal and Crankshaft Wear Sleeve (Remove and Install)

Crankshaft Rear Seal

Removal Procedure

Remove the flywheel housing.



The assembly of the crankshaft rear seal is nonserviceable. If the assembly of the crankshaft rear seal is removed, the assembly must be replaced. Remove the torx screws (1) from the assembly of the crankshaft rear seal (2).
Use Tooling in order to remove the torx screws (3) from the assembly of the crankshaft rear seal. Remove the assembly of the crankshaft rear seal (2) from the cylinder block. Discard the assembly of the crankshaft rear seal (2). It is not necessary to remove the adapter for the engine oil pan in order to remove the crankshaft rear seal.

Installation Procedure With Oil Pan in Position



Ensure that the crankshaft palm (1) is clean, dry and free from damage. If the crankshaft palm is worn or damaged, install a crankshaft wear sleeve. Ensure that the mating face of the cylinder block is clean and dry. Ensure that the mating face of the isolating frame (7) is clean and dry.

EEnsure that the plastic sleeve (3) is squarely installed within the new crankshaft rear seal (2). The plastic sleeve (3) is included in order to protect the lip of the seal as the crankshaft rear seal is pushed over the crankshaft palm (1). Do not attempt to install a crankshaft rear seal without the plastic sleeve.



Place the assembly of the crankshaft rear seal over the crankshaft palm (1). Align the dowel (5) with the slot in the crankshaft rear seal (2). Ensure that the plastic sleeve (3) is engaged on the crankshaft palm (1). Push the crankshaft rear seal (2) squarely onto the crankshaft. Ensure that the crankshaft rear seal is seated against the cylinder block.

During this process, the plastic sleeve (3) will be forced out of the crankshaft rear seal. Discard the plastic sleeve. Ensure that the dowel (5) is engaged in the slot in the crankshaft rear seal. Use Tooling in order to install the two outer torx screws (6) at the base of the crankshaft rear seal (2). Tighten the torx screws (6) to a torque of 15 Nm (11 lb ft).

Install:
- two torx screws (4) to the crankshaft rear seal (2) at position (X). Tighten the two torx screws (4) to a torque of 22 Nm (16 lb ft). Use Tooling in order to unscrew the two torx screws (6) at the base of the crankshaft rear seal (2) one complete turn.
- the remaining torx screws (4). Tighten the torx screws (4) to a torque of 22 Nm (16 lb ft). Use Tooling in order to install the remaining torx screws (6). Tighten all torx screws (6) at the base of the crankshaft rear seal to a torque of 22 Nm (16 lb ft).
- the flywheel housing.

Installation Procedure Without Isolating Frame for the Oil Pan

TThe crankshaft rear seal and the housing for the crankshaft rear seal are manufactured as one assembly. The crankshaft rear seal is lubricated during manufacture. Do not lubricate the seal or the crankshaft palm before installation. Never install a used crankshaft rear seal.



Alignment tool

To install the crankshaft rear seal without the isolating frame for the oil pan in position, Tooling must be used. The tool should be fabricated from 8 mm (5/16 inch) steel stock. The dimensions for the tool are given in Illustration. All dimensions are shown in millimeters.



Ensure that the crankshaft palm (1) is clean, dry and free from damage. If the crankshaft palm is worn or damaged, install a crankshaft wear sleeve. Ensure that the mating face of the cylinder block is clean and dry. Ensure that the plastic sleeve (3) is squarely installed within the new crankshaft rear seal (2).



Place the assembly of the crankshaft rear seal over the crankshaft palm (1). Align the dowel (5) with the slot in the crankshaft rear seal. Ensure that the plastic sleeve (3) is engaged on the crankshaft palm (1). Push the crankshaft rear seal (2) squarely onto the crankshaft. Ensure that the crankshaft rear seal is seated against the cylinder block. During this process, the plastic sleeve (3) will be forced out of the crankshaft rear seal. Discard the plastic sleeve. Ensure that the dowel (5) is engaged in the hole in the crankshaft rear seal.

Install:
- the Tooling to the cylinder block and to the crankshaft rear seal (2). Tighten the four M8 setscrews to a torque of 15 Nm (11 lb ft).
- two torx screws (4) to the crankshaft rear seal (3) in position (X). Tighten the two torx screws (4) to a torque of 22 N·m (16 lb ft). Unscrew the two M8 screws of Tooling that are installed to the base of the crankshaft rear seal (2) one complete turn.
- the remaining torx screws (4). Tighten all torx screws (4) to a torque of 22 N·m (16 lb ft). Remove Tooling.

Crankshaft Wear Sleeve (Rear)

Removal Procedure

Remove the crankshaft rear seal. Wear sleeves are used to reclaim worn seal surfaces or damaged seal surfaces. Wear sleeves are not original equipment.



Use a sharp tool to score a deep line across the crankshaft wear sleeve (1). Take care to avoid damaging the crankshaft. Insert a thin blade between the crankshaft wear sleeve (1) and the crankshaft (2) below the scored line. The crankshaft wear sleeve will separate along the line. Remove the crankshaft wear sleeve (1) from the crankshaft (2). Discard the crankshaft wear sleeve.

Installation Procedure

EEnsure that the crankshaft is thoroughly clean and dry.



Apply a small continuous bead of Tooling to the inner surface of crankshaft wear sleeve (1) at position X. Apply the bead of Tooling 5.00 mm (0.2 inch) from the flange end of crankshaft wear sleeve.



Align the crankshaft wear sleeve (1) with the crankshaft (2). Position the installation tool (3) that is provided with the crankshaft wear sleeve over the crankshaft. Use a hammer to drive the crankshaft wear sleeve onto the crankshaft. Ensure that the flange of the crankshaft wear sleeve is 0.40 to 0.60 mm (0.017 to 0.024 inch) from the cylinder block.

Measure the distance (Y) between the flange of the crankshaft wear sleeve (1) and the cylinder block in two places that are 180 degrees from each other. Remove the installation tool (3). Ensure that the crankshaft wear sleeve has no rough edges. Install a new crankshaft rear seal.
