REMOVAL
1. Turn the crankshaft to bring the 0° mark in line with the timing mark (top dead center for No. 1 and No. 4 cylinders) and remove the camshafts (all
valves are closed in this position). Place a cover over the timing-cover aperture to prevent collets or seals falling inside.
2. Using magnetic tool 83 91 401, or equivalent lift out the cam-followers.
NOTE: Place all valve parts in order in stand 83 93 787, or equivalent to ensure that they are refitted in their original positions.
3. Fit protective sleeves 8393746 over the valve springs to prevent the tappet guides from being scored. Note how the sleeves are fitted.
