Sealing Compound Application
NOTE:
Unless otherwise specify, the procedure
to apply the sealant is the same for right or left
cover.
Clean all metal components in a solvent.
Gearbox housing mating surfaces are best
cleaned using 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
the gear housing 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 mm - 75 mm
(2 in - 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 gear housing mating
surfaces.
F12R17A
Do not apply in excess as it will spread out inside
gear housing.
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).
Left Cover
Apply sealing compound on mating surfaces of
central housing. Refer to
