To Reassemble
1. Fit oil feed connection to rocker shaft and secure with the locating screw, ensuring that the screw enters the locating hole in the shaft.2. Refit the support brackets, springs, and rocker levers in the correct order (Fig. E.4). The support brackets are interchangeable and when fitting them ensure that the securing stud/setscrew holes are to the right viewing the shaft from the front end, with each pair of rockers inclined away from each other at the valve end.3. Fit securing washer and circlip to each end of the shaft.Push Rods
Check the push rods for straightness. If any are bent, fit replacements.Valve Stem Oil Seals
Where oversize valves are fitted, always ensure that correct size valve seals or 'O' rings are used.
E3 1. Collets2. Valve Spring Cap3. Oil Deflector4. Inner Valve Spring5. Outer Valve Spring6. Valve Spring Seat7. Exhaust Valve8. Inlet ValveAll hydraulically governed engines and certain mechanically governed engines have rubber oil deflectors fitted to inlet valve stems only (see Fig. E.3). When fitting these oil deflectors, the open end should be towards the cylinder head.With the majority of mechanically governed engines, oil seals are fitted to both inlet and exhaust valves. Earlier engines had a shallow rubber oil deflector fitted to the valve stems and positioned above the conical valve spring seating collar, the open end of the deflector being fitted towards the cylinder head. Later engines have a thin valve spring seating washer and a rubber oil seal which fits over the integral valve guide protrusion. In some cases, this latter seal has a nylon insert. The later sealing arrangement, due to a change in the diameter of the valve guide protrusion, is not interchangeable with the earlier sealing arrangement.On some engines, the seals are manufactured from Viton or silicon rubber material and they have a garter spring fitted around their outer circumference.In manufacturing, some engines have a red coloured material for inlet valve seals and black for exhaust valve seals. The red seal may only be fitted over the inlet valve. It is unsuitable for exhaust valves but the black seal may be fitted to either exhaust or inlet.The 4.2482 engine has a valve stem oil seal on both inlet and exhaust valves. The seals have garter springs round the seal neck for improved oil control.To Re-Assemble the Cylinder Head
1. Lightly oil valve stems.2. Fit valve to its correct guide or bore.3. Fit valve stem oil seals.4. Locate spring seat washers, valve springs and spring caps in position.5. Compress each valve spring and fit the valve collets.
E11, Valve Cap Sealing Arrangement As from Engine No. LD-----U778518H, 'O' ring seals have been fitted in the valve spring caps under the collets. The valve spring caps have been changed which have a deeper body so that the seal can be fitted as shown in Fig. E.11. The new caps are fitted to both valves, but the seals are fitted to exhaust valves only. T4.236 engines have two 'O' rings fitted in each valve spring cap.Cylinder Head
