60. Measure the thickness of gasket (B) with mi-
crometer 9999701.
61. Measure the height of flange (C) on the adapter
housing.
Example:
a) When distance (A) is measured, we obtain a dis-
tance of 5.70 mm in this case.
b) Gasket (B) thickness is measured as 0.30 mm.
c) Flange height (C) is measured as 3.85 mm.
A + B – C = shim thickness
5.70 + 0.30 – 3.85 = 2.15
Shim thickness = 2.15 mm

62. Install the calculated thickness of shims and gas-
ket on the division plane of the lower gear housing.
NOTE! The text on the gasket must face upwards.
The hole pattern in the gasket only fits one way round.
63. Install the adapter housing with rubber sleeve on
the lower gearing housing. Apply MoS

Volvo Penta part no. 1161029-2 to the socket cap
screws. Put washers on the six socket cap screws
and use a torque wrench to tighten them.
Tightening torque: 30 Nm (22.13 lbf ft).
NOTE! Torque the screws diagonally, then re-check
their tightening.
Install the cooling water tap on the port side. Apply
sealant, Volvo Penta part no. 1141570-0 on the
threads.
NOTE! Check that the adapter flange has entered the
gear housing and presses the shims down, so that
there is no end float in the vertical shaft. Also check
the flank clearance.
