Typical example
Apply clean grease to Tooling (A) in order to prevent any swarf that is generated from entering the engine. Use Tooling (A) to drill three evenly spaced holes in crankshaft front seal (1).
Use Tooling (B) with care in order to remove crankshaft front seal (1) from front cover (3) and crankshaft pulley adaptor (4). Alternate the position of Tooling (B) from one hole to another. Alternating the position of Tooling (B) will allow the crankshaft front seal to be easily removed from the crankshaft.
If inner section (2) of crankshaft front seal (1) remains on crankshaft pulley adaptor (4). Use a suitable tool to remove the inner section of the crankshaft oil seal from the crankshaft pulley adaptor. Ensure that the crankshaft pulley adaptor and front cover (3) are not damaged as the inner section is removed.
