4. Fit the piston and connecting rod assembly into the
liner.
5. Fit the liner into the crankcase ensuring that the
arrow on the piston faces forward, and the oil hole in
the connecting rod faces rearward.
NOTE:
• Ensure that the pist()n/liner/connectlng rod
assembly aligns correctly with the crankpln

8. Align the connecting rod to the crankshaft and fit the
big end cap. Tighten the cap (using new nuts and
bolts) as follows:
Lubricate the threads of the bolt and the face of the
nut with molybdenum disulphide grease. Tighten
the nuts progressively in 2 stages;-
' " CAUTION: The torque characteristics of
~
the connecting rod nuts and bolts are
sensitive to the rate at which they are tightened. If
all the torque is applied in one action, the bolt may
be stretched and the nut may become loose when
in service resulting in an expensive engine failure.

using the Triumph torque turn gauge
3880105-T0301.
To accurately gauge the 120
0
turn, fit the tool
between the socket and the drive handle and locate
the socket to the big end nut. Pick an increment
point on the torque turn gauge which aligns with a
suitable reference point. Tighten the bolts until 12 of
the 10
0
gauge increments have rotated past the
chosen point.
