To dismantle and inspect

Operation 3-6

1  Remove the circlip from the end of the rocker shaft.

2  Slide all of the components from the shaft and put them on a bench in the correct sequence.

3  Inspect all of the components for signs of damage.

4  Check the rocker shaft, the rocker levers and the bushes for deep scratches or signs of excessive wear.

5  The bushes of the rocker lever have a groove to assist with lubrication, ensure that the grooves are free from

debris.

6  Measure the internal diameter of the bushes at two places 90° apart and record the readings.

7  Measure the external diameter of the rocker shaft at two places 90° apart where it contacts the bushes of

the rocker levers. Record the readings.

8  If the difference between the measurements is greater than 0,13mm (0.005 in), renew the worn component,

either the shaft or the bushes.

9  Ensure that all the lubricating oil holes and passages of the rocker shaft assembly are free of debris.

10  Check the plugs at the ends of the rocker shaft for leaks or damage.

11  Measure and record the free length of the rocker shaft springs.

12  Measure and record the length of the springs when a load of 31N (7 lbf) 3,2 kgf is applied. Compare both

measurements with those given in the relevant Data and dimensions for the "Rocker shaft springs" on page 12.

13  Renew any springs that are not within the tolerance.

9  For WK, WL, WM, and WN engines: tighten evenly and gradually all of the cylinder head setscrews as

follows:

l   150 Nm (110 lbf ft) 15 kgf m in the sequence shown in (B)

l   210 Nm (155 lbf ft) 21,5 kgf m in the sequence shown in (B)

l   225 Nm (165 lbf ft) 23,0 kgf m in the sequence shown in (B)

l   Then proceed to step 13.

10  For WP, WQ, WR and WS engines: Position the crankshaft at TDC for number 1 cylinder, and then rotate

the crankshaft 30° past TDC.

Caution: As the cylinder head setscrews are tightened to yield point, the setscrews must be tested for

extension by use of special tool (27610202). Renew any setscrew that fails. If the special tool is not available,

then all of the setscrews must be renewed.

11  The threaded special tool is fitted on to each cylinder head setscrew. The setscrew must be renewed if the

tool becomes tight on the setscrew thread. This tightness indicates that the setscrew thread is extended and

the setscrew must be discarded.

12  The cylinder head setscrews must be tightened as follows. Tighten evenly all of the setscrews in the

sequence shown in (B) to 135 Nm (100 lbf ft) 13,8 kgf m.

l   Tighten each cylinder head setscrew to 177 Nm (130 lbf ft) 18 kgf m in the sequence shown in (B).

l   Repeat this step to ensure even tightness.

l   Tighten the setscrews in the same sequence by a further 90°. To do this, apply a mark (C1) to each

setscrew head or socket spanner, and another mark (C2) at 90° clockwise on the cylinder head surface as

shown. Tighten each setscrew until the two marks align.

Caution: Chlorinated solvents must not be used on setscrews or crankcase tapped holes. Components should

be clean and dry, and free of any chemical contamination other than engine oil.

Valve depth gauge

1  Remove the cylinder head, see Operation 3-8.

2  Put a small amount of low viscosity oil, for example calibration fluid, into the inlet and exhaust ports then

check for leakage.

3  Wait five minutes, then check again for leakage.

Note: If no oil leaks past the valve seat, it does not need to be reground.

4  Ensure that the heads of the valves and the face of the cylinder head are clean.

5  Check the depth of the valves below the face of the cylinder head before the valve springs are removed. Put

the valve depth gauge on the face of the cylinder head and set the dial gauge to zero. Carefully put the valve

depth gauge in position over the head of each valve (A) and compare the measurement with the relevant Data

and dimensions for the "Inlet and exhaust valves" on page 10.

6  If a valve is below the depth limit, check the valve depth with a new valve in position.

7  If the valve depth is still below the limit, the valve seat insert must be renewed, see Operation 3-19.

8  Remove the valves and valve springs, see Operation 3-10.

9  Visually inspect the condition of the collets.

10  Visually inspect the valve springs for corrosion, for damage or distortion.

11  Check that the end faces of the springs are square and flat.

12  Measure the free length of the valve springs (B) and compare it with the relevant Data and dimensions for

the "Valve guides and springs" on page 11.

14  Check the valves for cracks. Check the stems for wear and correct fit in their valve guides.

15  Check that the seat faces of the valves are not badly burnt or damaged. Seat faces of valves that are

damaged can be ground on a special machine. Valves that have only a little damage can be lapped to their

valve seats. When new valves are fitted, the valve depths must be checked.

16  Measure the valve dimensions and compare them with the relevant Data and dimensions for the "Inlet and

exhaust valves" on page 10.

2  To test the operation of the rotator (A4), put a valve spring (A3), the valve rotator and a steel ball bearing

(A5) in a valve spring tester (A1).

3  Mark the rotator with a reference line (A2).

4  Compress the valve spring rapidly several times and check that the rotator rotates.
