ENGINE REASSEMBLY

Timing chain tensioner installation

Refit the chain tensioner (12) and its gasket. Tighten the two screws (13) using
an 8 mm wrench (10, Nm, 1.0 Kgm, 7.25 ft/lb).
WARNING
On TE and TCX models, the two retaining screws feature two different
lengths.
Screw 13A = L.25 mm
Screw 13 = L.20 mm
On assembly, position the screw (13a) at the uppermost position and fit the
ground rings (14) before tightening.
IMPORTANT
Do not confuse the screws and do not tighten the screw (13a) unless you
have fitted the ground rings; RISK OF CYLINDER FAILURE.
Release the chain tensioner (12) using a screwdriver (turn counter clockwise).
Water pump installation
Refit the water pump (1) with its gasket. Avoid using excessive force to engage
pump gear with intake camshaft gear. Tighten the screws (2) with a 4 mm Allen
wrench (5.5 Nm, 0.5 Kgm, 3.98 ft/lb).
