1. Bearing protrusion in cylinder block notch
Apply engine oil on all bearings, in the bottom area
of the cylinder bore and also on the band of the
piston ring compressor tool.
For proper installation of pistons, refer to PISTON/
CONNECTING ROD in this section.
NOTE:
Before installing the crankshaft, make sure
that the timing chain is on the crankshaft and the
chain guide has been installed first. Those parts
cannot be installed after as the crankshaft is in
place.
Clean oil passages and make sure they are not
clogged.
Clean all metal components in a solvent.
cylinder block mating surfaces are best cleaned
using a combination of the 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).
CAUTION:
Do not wipe with rags. Use a new
clean hand towel only.
IMPORTANT:
When beginning the application of
the crankcase 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.
NOTE:
It is recommended to apply this specific
sealant as described here to get an uniform appli-
cation without lumps. If you do not use the roller
method, you may use your finger to uniformly dis-
tribute this sealant.
Use the silicone-based Loctite 5910 (P/N 293 800
081) on mating surfaces.
CAUTION:
Do not use other products to seal
crankcase. Do not use an activator with the
Loctite 5910. Using other products or non sil-
icone-based sealant over a previously sealed
crankcase with Loctite 5910 will lead to poor
adhesion and possibly a leaking crankcase.
NOTE:
Refer to the product label for the sealant
curing time. Respect the manufacturer's recom-
mendations prior to start engine.
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 printmak-
ing) and roll the sealant to get a thin uniform coat
on the plate (spread as necessary). When ready,
apply the sealant on crankcase mating surfaces.
F12R17A
Do not apply in excess as it will spread out inside
crankcase.
Tighten cylinder block screws as per following pro-
cedure:
Apply Loctite 243 (blue) (P/N 293 800 060) on
screw threads.
