Dismantling of a head of the block of cylinders

Completely disassemble the block head.

Clamp the head in a vice on the bracket screwed to the exhaust manifold studs. Gradually and alternately on each side, unscrew the bolts securing the bearing caps number 1, 3 and 5 (see fig. 42). Also unscrew both bolts from the end bearing cover. Loosen the number 2 and number 4 bearing cap nuts by two turns, «criss-cross», and then unscrew. Remove both covers and remove the camshaft. Immediately inspect the earbuds and labels for correct installation. ledge «A», shown in Fig. 42 is located on the intake manifold side, and the numbers on the covers «IN» must be read when viewed from the exhaust manifold.



Take out the pushers. They cannot be interchanged and therefore should be marked, for example, with strokes on the inside (the first pusher - one stroke, the second - two, etc. - see fig. 43). The tappets should be placed with the surface in contact with the camshaft cam down so that oil does not leak from the inside.



For proper disassembly of the valve mechanism, a special tool is required, shown in fig. 44. With the rod of tool VW541 / 1, press on the upper plate, compressing the spring so that the crackers can be removed. To remove the valves, you can use a short piece of pipe that is installed on the top plate. Support the valve head well. Release the crackers with light blows of a hammer on the pipe. They will remain inside the pipe, so care must be taken that they are not lost.




Take out the plates and springs. Remove the oil seal and discard it immediately as it must be replaced with a new one. On fig. 45 shows the remaining components and parts of the cylinder head after removing the camshaft.
