Confirm that both of the Ring Seals are not protruding in any direction.
NOTE: If the reduction gear shaft is not going to be immediately installed, the
Split Ring Seal Cover (#J-52595-4) can be slid over both Ring Seals to prevent
damage.
CAUTION: in the following step use extreme care when installing the final drive and
reduction gear assembly.
The machine cut seals are VERY delicate and will damage easily if forced.
The reduction gear assembly should seat without any additional force.
If the reduction gear assembly does not seat, remove it and confirm that machine cut
seals are in place and centered in their grooves.

IMPORTANT:
Confirm that the mating surfaces are clean before applying sealant.
Make sure that the starting point and the ending point of the sealant is
between two bolt holes. Overlap both ends of the bead by 3 – 5 mm.
If the Guide Pins were removed to clean the case surfaces, reinstall them
now.
CAUTION: Be careful not to contact or contaminate the sealant. If the sealant has
been disturbed or contaminated in any way before case assembly, remove the
sealant completely and re-apply.
