Balancer unit

To remove and to fit Operation 5-18
To remove
1 Drain the lubricating oil from the sump and remove the sump, see Operation 10-3.
Warning! The weight of the unit is approximately 25 kg (55 lb).
2 Provide a support for the balancer unit before the setscrews are released from the engine.
3 Release the setscrews and lower carefully the balancer unit. Make a note of the positions of the setscrews
of different lengths.
To fit
1 Ensure that the contact faces of the cylinder block and of the balancer unit are clean and that the two
thimbles (A1) are fitted correctly to the cylinder block.
2 Set the piston of number 1 cylinder to TDC, see Operation 8-1 or Operation 8-2.
3 Before the balancer unit is fitted, ensure that the flat faces of the balance weights are level with each other
(B1) and the weights hang down away from the cylinder block (B2). The timing of the balance weights to the
drive shaft is correct when the large hole and small hole in the front of the drive shaft gear are in the positions
shown in the illustration (B).
Note: If the gear position shown in (B) cannot be obtained, then the balancer must be partially dismantled and
the timing corrected, see Operation 5-19 and Operation 5-20.
4 Fit the balancer unit to the cylinder block with the correct screws in the centre positions of the balancer frame.
Ensure, when the idler and crankshaft gears are in mesh, that the flat faces of the balance weight are level
with each other and that they are towards the cylinder block. Check that the balancer unit is fitted correctly on
the thimbles and fit the remainder of the setscrews in their correct position. Tighten the setscrews to 54 Nm
(40 lbf ft) 5,5 kgf m.
5 Rotate the crankshaft through two turns to ensure that it is free to rotate.
6 Fit the lubricating oil sump, see Operation 10-3 and fill the sump to the correct level with an approved oil.
