Engines are intricate, especially during their servicing, and especially timing chains and
Camshaft servicing or if there is a
Cylinder Head change. It would he wise to do a lot of research before undertaking the repairs and if at any one time you are in doubt, perhaps it is wise to seek professional help. The removal process starts with the removal of the negative battery terminal and the spark plugs with cylinder number one positioned at the top dead centre. Valve covers and timing chain covers must be removed, after which the crankshaft position sensor toothed wheel must also be removed, while taking note of its installed direction. The crankshaft has to be rotated such that it aligns to certain timing marks and various tools have to be used to lock the camshaft from rotating. Timing chain tensioners and chains are then released and pulled out together with the stationary guides and if required the camshaft sprockets can also be interchanged. Different procedures to do with the removal of
Rocker Arms, the inspection of sprocket teeth as well as the examination of the condition of chains are provided for different engine types, and there is a strong recommendation that worn out parts be replaced. Among them are timing chain guides and sprockets that require proper installation and positioning; and tensioners that have to be compressed prior to any lock to keep the engines well functioning. Following these procedures the rocker arms are fitted and with the crankshaft turned an increase in friction is detected showing problems. The final step of the installation process is the reversal of the removal process with due focus being paid on replacement of all Timing marks and other related parts.
