Ford CVH engine camshaft removal and refitting - is a part of Ford repair manuals: Ford CVH Engines. This part contains the detailed description and diagrams for Ford CVH engine camshaft removal and refitting.
Ford CVH engine camshaft removal:
- disconnect the pipes and remove the windscreen washer fluid reservoir from the engine compartment;
- disconnect the HT leads from the spark plugs, then remove the distributor cap and secure it to the left-hand side of the engine compartment;
- unscrew the three bolts and withdraw the distributor from the cylinder head; note that the distributor body is marked in relation to the cylinder head;
- unbolt and remove the fuel pump, complete with coil spring;
- withdraw the insulating spacer and operating pushrod;
- unbolt the throttle cable bracket at the carburettor and then disconnect the cable by sliding back the spring clip;
- remove the timing belt cover-to-cylinder head attachment bolts;
- remove the rocker cover;
- unscrew the securing nuts and remove the rocker arms and guides;
- keep the components in their originally installed sequence by marking them with a piece of numbered tape or by using a suitably sub-divided box;
- withdraw the hydraulic cam followers, again keeping them in their originally fitted sequence;
- slacken the alternator mounting and adjuster link bolts, push the alternator in towards the engine and slip the drivebelt from the pulleys;
- unbolt and remove the timing belt cover and turn the crankshaft to align the timing mark on the camshaft sprocket with the one on the cylinder head;
- slacken the bolts on the timing belt tensioner, lever the tensioner against the tension of its coil spring (if fitted) and retighten the bolts;
- with the belt now slack, slip it from the camshaft sprocket;
- pass a rod or large screwdriver through one of the holes in the camshaft sprocket to lock it and unscrew the sprocket bolt;
- remove the sprocket;
- extract the two bolts and pull out the camshaft thrust plate;
- carefully withdraw the camshaft from the distributor end of the cylinder head.
Ford CVH engine camshaft refitting:
- refitting the camshaft is a reversal of removal, but observe the following points;
- lubricate the camshaft bearings before inserting the camshaft into the cylinder head;
- it is recommended that a new oil seal is always fitted after the camshaft has been installed;
- apply thread-locking compound to the sprocket bolt threads;
- fit and tension the timing belt;
- oil the hydraulic cam followers with hypoid type transmission oil before inserting them into their original bores;
- refit the rocker arms and guides in their original sequence, use new nuts and tighten to the specified torque;
- it is essential that before each rocker arm is installed and its nut tightened, the respective cam follower is positioned at its lowest point (in contact with cam base circle);
- turn the camshaft (by means of the crankshaft pulley bolt) as necessary to achieve this;
- use a new rocker cover gasket;
- do not forget to refit the timing belt cover bolts.
