Operation 5-14

1  Drain the lubricating oil and remove the sump, see Operation 10-9.

2  Remove all necessary components to get access to the specific bearing cap.

3  Release the setscrews of the bearing cap and remove the bearing cap (A).

4  Remove the lower shell-bearing from the cap.

5  With a suitable tool, push the upper shell-bearing from the side opposite to the location tag to remove the

bearing tag from its recess in the bearing housing.

To fit

Operation 5-15

1  Clean the upper shell-bearing and lubricate the bearing surface with clean engine lubricating oil.

2  Fit the plain end of the upper shell-bearing between the crankshaft journal and the side of the bearing

housing which has the recess for the location tag. Slide the bearing into its housing until the tag on the bearing

is fitted correctly in its recess in the housing.

3  Clean the lower shell-bearing and the cap, lubricate the bearing surface with clean engine lubricating oil.

4  Fit the bearing into the cap with the tag of the bearing fitted correctly in the recess in the cap.

5  Fit the bearing cap with the location tags of both shell-bearings on the same side.

6  Lightly lubricate the setscrews with clean engine lubricating oil.

7  Fit the setscrews for the main bearing caps numbers 1 to 6, and tighten the setscrews gradually and evenly

to the specific torques shown below:

WK, WL, WM, and WN engines - 157 Nm (116 lbf ft) 16,0 kgf m

WK, WL, WM, and WN engines (from engine serial number 850000) - 176 Nm (130 lbf ft) 18,0 kgf m.

Caution: For WP, WQ, WR, and WS engines, new setscrews must be fitted whenever bearing caps are fitted.

For WP, WQ, WR, and WS engines:

Tighten each main bearing cap setscrew evenly and gradually to 135 Nm (100 lbf ft) 13,8 kgf m.

Tighten each main bearing cap setscrew to 177 Nm (130 lbf ft) 18,0 kgf m.

8  Ensure that the crankshaft rotates freely. If the thrust bearing (number 7) has been removed and fitted, check

the crankshaft end-float, see Operation 5-11.

9  For WP, WQ, WR, and WS engines, tighten all the main bearing cap setscrews a further 90°. To do this,

apply a mark (A1) to each setscrew head or socket spanner, and another mark (A2) at 90° clockwise on the

crankcase surface as shown. Tighten each setscrew until the two marks align (A3).

10  Fit all the components that were removed for access to the main bearing caps.

11  Fit the lubricating oil sump, see Operation 10-10.

12  Fill the lubricating oil sump to the correct level with an approved lubricating oil, see Chapter 5 in the User’s

Handbook.

Timing case and drive assembly

6

General description

The aluminium timing case, which is a two piece casting, contains the drive gears. There are two idler gears:

the lower idler gear (A4) and the upper idler gear (A2). The lower idler gear is driven by the crankshaft gear

(A5) and drives the upper idler gear and, if fitted, the compressor. The upper idler gear drives the camshaft

gear (A1) and the gear (A3) for the high-pressure pump. All of the gears have timing marks except the gear for

the high-pressure pump. There is a spline on the crankshaft nose to drive the lubricating oil pump. A power

take-off can be fitted to the right hand side of the engine. If one is fitted, it is driven by the lower idler gear.

The idler gears are mounted on taper roller bearings.

The camshaft gear rotates at half engine speed.

The timing case assembly has channels and ports for the coolant and for the lubricating oil. This reduces the

need for external pipes and improves engine reliability.

The camshaft rotates in four bushes that can be renewed.

Idler gears

To remove

Operation 6-3

Cautions:

l   The setscrew for the upper idler gear (C1) enters the water jacket. To prevent leakage of coolant, the

setscrew is supplied with a sealant on its thread.

l   The setscrew for the upper idler gear must be renewed when it is removed from the engine.

1  Set number 1 cylinder to TDC on the compression stroke, see Operation 8-1.

2  Drain the cooling system.

3  Remove the timing case cover, see Operation 6-1.

4  Measure and record the backlash of the upper idler gear (A). Measure and record the backlash of the lower

idler gear (B). Compare the results with the relevant Data and dimensions for the "Timing gears" on page 15.

Renew any gear that is out of tolerance.

5  Remove and discard the setscrew of the upper idler gear. Remove the upper idler gear.

6  Remove the setscrew of the lower idler gear and remove the lower idler gear (C2).

Caution: If the crankshaft is rotated with either of the idler gears removed, the timing of the engine will be

To fit

Operation 6-4

Caution: Ensure that the piston of number 1 cylinder is set to TDC.

1  Lubricate the bearings of the idler gears with clean engine lubricating oil.

2  Lightly lubricate the threads and shoulder of the setscrew for the lower idler gear with clean engine

lubricating oil.

3  Put the lower idler gear (A4) in position and in mesh with the crankshaft gear (A5) so that the timing marks

align (A).

4  Fit and tighten the setscrew to 637 Nm (470 lbf ft) 65,6 kgf m.

5  Ensure that the thread in the cylinder block for the setscrew of the upper idler gear is clean and dry.

6  The new setscrew for the upper idler gear (A2) is supplied with a sealant on its thread. Do not add more

sealant to the thread of the setscrew. Do not apply lubricating oil to the thread of this setscrew.

7  Put the upper idler gear in position and in mesh with the camshaft gear (A1), the lower idler gear and the

high-pressure pump gear (A3). Ensure that the timing marks (A) align on the upper idler gear, the camshaft

gear, the crankshaft gear and the lower idler gear.

Note: There are no timing marks on the high-pressure pump gear.

8  Fit and tighten the new setscrew for the upper idler gear to 332 Nm (245 lbf ft) 33,8 kgf m.

9  Check that the backlash of the gears is still within tolerance. Renew any gear that is out of tolerance.
