Clean all metal components in a solvent.
Housing mating surfaces are best cleaned us-
ing a combination of
LOCTITE CHISEL (GASKET
REMOVER) (P/N 413 708 500)
and a brass brush.
Brush a first pass in one direction then make the
final brushing perpendicularly (90°) to the first
pass cross (hatch).
NOTICE
Do not wipe with rags. Use a new
clean hand towel only.
IMPORTANT:
When beginning the application
of sealant, the assembly and the first torquing
should be done within 10 minutes. It is suggested
to have all you need on hand to save time.
Use
LOCTITE 5910 (P/N 293 800 081)
on mating sur-
faces.
Use a plexiglass plate and apply some sealant on
it. Use a soft rubber roller (50 - 75 mm (2 - 3 in)),
available in arts products suppliers for printing,
and roll the sealant to get a thin uniform coat
on the plate (spread as necessary). When ready,
apply the sealant on housing mating surfaces.

Do not apply in excess as it will spread out inside
housings.
NOTE:
It is recommended to apply this specific
sealant as described here to get a uniform appli-
cation without lumps. If you do not use the roller
method, you may use your finger to uniformly dis-
tribute the sealant (using a finger will not affect
the adhesion).
Install all other screws on right housing then the
O-ring and the distance sleeve on end of output
shaft. Chamfered bore of distance sleeve has to
face the engine.

sequence to following specification.
