Apply a small continuous bead of Tooling (A) to the inner surface of crankshaft wear sleeve (1) at position X. Apply the bead of Tooling (A) 5.00 mm (0.2 inch) from the flange end of the crankshaft wear sleeve.
Align crankshaft wear sleeve (1) with crankshaft (2). Position 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 dimension (Y) is 6.5 mm (0.26 inch). Note: Dimension (Y) is the distance from the edge of the crankshaft wear sleeve from the rear face of the crankshaft.
Remove installation tool (3).
Use a suitable tool to cut down to Scored Line (Z) on crankshaft wear sleeve (1) and remove the curved section of the crankshaft wear sleeve.Ensure that the crankshaft rear seal surface of the crankshaft wear sleeve is not distorted or damaged as the curved section of the crankshaft wear sleeve is removed. Note: Ensure that the crankshaft wear sleeve has no rough edges, if crankshaft wear sleeve has rough edges use suitable tooling to clean the rough edges.End By:
Install a new crankshaft rear seal. Refer to Disassembly and Assembly, "Crankshaft Rear Seal - Remove and Install" for the correct procedure.
