How to remove the Timing Chain, Timing Chain Tensioner and Timing Cover on Mazda 3?

The timing chain cover can be removed by firstly disconnecting the negative battery terminal by first removing the battery cover. Unscrew the water pump pulleys bolts and take out the drive belt, drive belt idler pulley and the water pump pulley. The second step is to take the crankshaft pulley off making sure that the engine does not leave TDC. Removal of the upper engine cover: Lift off the engine cover uppermost on the mounting posts and disconnect the electrical connector of Crankshaft Position (CKP) sensor, and remove the sensor, remember that sensor needs to be replaced every time. Access the engine by lifting it at the top and lift it so that one can take off the engine mount to the right and should one be required, loosen the mounting bracket and lay aside the power steering hoses. Take off the timing chain cover by removing the crankshaft front oil seal then the bolts. Installation requires reversal of the removal instructions with the note to clean all surfaces of the parts of the sealant mating, installing the engine cover within the four minutes following the application of RTV sealant, tightening the bolts in sequence to the recommended torque, and fitting a new CKP sensor with the alignment tool without tightening the mounting bolts of the sensor. In order to strip the timing chain and tensioner, you have to remove the timing chain cover, then pull the ratchet arm of the tensioner couple of inches away by the ratchet stem and press the tensioner piston by pushing on it using a pin. In the event that the ratchet requires resetting, put the tensioner in the vise, release the tension and put the ratchet back in place. Disassemble the tensioner mounting bolts and tensioner, the loose timing chain guide and timing chain. The camshaft sprockets and guide to the left chain may be removed in case of necessity. To install, first remove the camshaft alignment tool (unless it was already installed), loosen the camshaft sprocket bolts but do not remove them and then install the left chain guide (unless removed). Next, place the timing chain and the right chain guide, the timing chain tensioner, screw the fastensers and then eliminate the pin to connect the chain guide. Tighten the bolts of the camshaft sprocket and install the camshaft alignment tool again, when doing so, do not depend on the alignment tool. Lastly, the timing chain cover could be fitted.

Mazda 3 Timing Cover

The Mazda 3 Timing Cover is an armored cover that covers the front of the engine to ensure that the belt or chain drive remains clean and in its proper position so that the valves and pistons remain in perfect synchronization. It is made of aluminum, plastic, or steel, fitted over the timing belt or timing chain, and, with the help of a built-in gasket, it prevents grit and moisture from the road from hitting the fine teeth that determine engine rhythm. It also eliminates the possibility of the belt or chain jumping a cog when the cover is screwed in place and maintains the exact timing that gives power and fuel efficiency their smooth operation. There were Timing Cover designs for the compact cars in Mazda that were created in the production years and that are applicable to the compact cars, with two main types of internal mechanisms, one of them being a belt-driven design and the other being a chain-driven design, but both based on the same fundamental design, which is the strong material held together by a tight-sealing gasket. Belt versions tend to be thinner since they simply have to pass under a flexible toothed belt, whereas chain versions have additional depth and strength to withstand the passage of moving metal links. No matter the style, a broken or bowed cover can give up its seal at any time, allowing debris to enter the engine and damage valuable engine components, and therefore immediate replacement is a key factor for any person who wants their Mazda to continue running smoothly. The Timing Cover should therefore be regarded as an initial point of defence and not a disposable part by the owners of the well-known Mazda 3.

The second step is to take the crankshaft pulley off making sure that the engine does not leave TDC.

Next, place the timing chain and the right chain guide, the timing chain tensioner, screw the fastensers and then eliminate the pin to connect the chain guide. Tighten the bolts of the camshaft sprocket and install the camshaft alignment tool again, when doing so, do not depend on the alignment tool. Lastly, the timing chain cover could be fitted.
