Figure 7. Installing the Chain
1.
Wrap the chain (T18) around the drive (T5) and driven (T26) sprockets
making sure everything meshes and then lace the joining ends togeth‐
er using the connecting pin set (
see Figure 7
).
2.
Insert the connecting pin rocker partway through the holes in the join‐
ing end links being careful of orientation (
see
Figure 9
). The connect‐
ing rocker must be on the side of the guide link opposite the joining
end with the connecting rockers wide curved surface towards the
center of the hole.
3.
Insert the connecting pin assembly along side the connecting rocker.
The two wide curved surfaces of the connecting pin and connecting
rocker must face each other.
4.
After the connecting pin assembly and connecting rocker have been
pushed all the way through the joining ends of the chain, insert the spirol
pin into the open hole at the end of the connecting pin assembly (
see
Figure 9
). Make sure the spirol pin overlaps the connecting rocker.
5.
Tighten cap screws connecting the driveshaft housing to the chain
case mid-section. Check chain for proper tension. Check deflection
half-way between the drive sprocket and driven sprocket (see chart
below for maximum deflection). Replace chain if deflection is greater
than those displayed in the chart below.
6.
Loosen drive shaft housing cap screws for installation of lower case.

Cap and Driven Shaft Assembly
1.
Make sure faces of flanges are clean and free of nicks and burrs.
2.
If applicable, clean shims (T99) and / or spacer(s) (T100).
3.
Install applicable dowel pins into mid-section (see appropriate SPL draw‐
ings). Apply a bead of silicone to mid-section flange inside of bolt holes. If
shims and spacers are required, install at this time. (For extended drop
cases built before 8/05/96, apply a bead of silicone between each spacer
inside of bolt pattern.)
4.
Apply a bead of silicone to the top surface of the last shim (T99) and
spacer (T100).
5.
Position previously assembled cap and driven shaft on dowels in the top
flange of the mid-section or spacer and tap down into contact with shims.
Install fasteners with lockwashers and tighten evenly.
NOTE: Fasteners used vary between models. Refer to the table in the
appropriate service parts lists for location and correct fasteners.
6.
Invert mid-section and cap.
