1. Install the seal (7) so that the spring side is facing the
intake side of the case and press it in so that it is bottomed
out in the case.
2. Install the mechanical seal (8) into the case with the sealant
facing the intake side of the engine. Use the Seal
Installation Tool PN 2872010.
IMPORTANT: It is very critical to use the Installation
tool PN 2872010 to set the operating height of the
mechanical seal. Failure to do so will cause seal to
leak.
