| The shims can be fitted either way up. When the valve clearance is correct, refit the sprocket assembly and locate the sprocket nut finger tight. It may be necessary to centralise the thrust washers between the camchain case and head when inserting the camshafts, using a small screwdriver. Do not forget to turn back any jacking screws before refitting the bearing housing, and use silicone RTV sealant on the mating faces. | |
VALVE TIMING. If the valve timing has been lost by dismantling the sprocket assembly, or when the crankcase timing gears have been disturbed, proceed as follows: |
|
| Position the engine so that one piston is at TDC on the firing stroke, (check the marks on the alternator). Fit the camshaft timing tool (8016) onto the cylinder head to hold the camshaft in place, (page 21). If both camshafts are removed, it is necessary to fit the sprocket assembly to the exhaust camshaft first. | |
| Fit the woodruff key and sprocket retaining plate to the camshaft. Offer up the sprocket, moving it round in the chain until the plain hole in the retaining plate aligns exactly with a sprocket hole. | |
