Question 1

What are the crucial steps and precautions to follow when working on the Timing Chain, Timing Chain Guide and Timing Chain Tensioner on Mazda 6?

Accepted Answer

It is a complicated timing system and serious engine damage may be achieved in case of errors; hence, only the most experienced people can have an attempt at such a procedure, and it is always important to check all work two times and then start engine on. In the case of a 3.0L, start by getting the timing chain cover off and slide the crankshaft position sensor trigger wheel off the crankshaft ensuring that the pulse wheel fits in its proper place. Disconnect the spark plugs, and observe that there are two timing chains, in which case the front chain is the one that is operating the camshaft sprockets on the rear cylinder head as well as the chain that is nearest to the block, operating the camshafts at the front. Install the crankshaft retaining bolt that has the pulley, spin the crankshaft clockwise until the keyway is at 11 o'clock position of the TDC and check the alignment of the camshaft sprockets. Take out the VCT assembly and timing chain tensioner of the rear chain and raise the rear timing chain out of the cam sprockets. Once the chain guide/VCT assembly is removed, it is necessary to slide the rear timing sprocket, rotate the crankshaft so as to position the camshafts in their neutral position and repeat these steps with the front timing chain. Special camshaft holding tools are needed in case of 3.7L engine and it is recommendable to replace water pump during this process. Once the timing chain cover is removed and the engine is set to TDC, the camshaft holding tools are to be installed, the VCT assembly mounting bolts removed, and the tensioners, labeling chain links where needed. Inspect and clean all components of wear or wear, and replace dubious components. Installation It is important to ensure that the tensioners of the timing chains are completely compressed and screwed, the colored links are properly aligned with the index marks, and all parts are properly in place before reassembling. Once the crankshaft is installed, test the crankshaft to confirm that it is free of any binding, secure the timing chain cover and refill the engine with oil and coolant before reconnecting the battery and start the engine to verify that there are no leaks.

Question 2

Is performing this procedure installed challenging due to limited clearance for Timing Chain, Timing Chain Guide and Timing Chain Tensioner on Mazda Tribute?

Accepted Answer

Because of minimal clearance, the task of installing the engine may be extremely difficult when it is still in the aircraft and may be simplified in case of the necessity to do extensive work. It is a complicated timing system and any error made may cause serious damage to the engine and this procedure should only be undertaken by very experienced people and an expert should be consulted in case of any doubt. The first step is to take the timing chain cover off and slide the crankshaft position sensor trigger wheel off the crankshaft then remove the spark plugs and mark the exact location of the pulse wheel so it can be replaced back. Install the crankshaft retaining bolt with the pulley and then turn the crankshaft clockwise until the 11 o'clock setting of the keyway, but make sure the 1 cylinder cylinder is at TDC at the compression stroke by checking the index marks on the camshaft sprockets. Ensure the alignment and then proceed to position the camshafts in their neutral range by rotating the crankshaft until all the bolts attaching the rear timing chain tensioner and its arm have been removed, labeling all reusable components and ensuring that they are reinstalled properly. Take the rear timing chain off the sprockets, the rear chain guide, and slide the rear timing chain sprocket off the crankshaft. Turn the crankshaft 600 degrees clockwise to position the camshafts of the front cylinder head with the armature to the neutral position, and then loosen the tensioner of the front timing chain and detach the arm, and lift the front timing chain off the sprockets. Wipe down everything with solvent and examine the chain tensioners, guides and chains to confirm they are in great shape, and change any parts that may be suspicious. Check Before proceeding to start the engine, the crankshaft must be turned by hand at least two full revolutions, with resistance. Install timing chain tensioners: Timing chain tensioners are prepared by compressing and locking in place and the crankshaft sprocket is installed in the front timing chain, with the keyway at 11 o'clock. Shim the index indices on the sprockets with colored links of the chain, fit the front timing chain guide and fix with bolts. Install front timing chain around the sprockets, again this must be properly aligned and follow this by attaching the front tensioner arm and assembly, and again making sure that everything is in place. Do the same procedures with the back timing chain making sure that everything in it is in place. Once all locking pins have been removed on the tensioners, turn the crankshaft back to the 11 o'clock position, fit the crankshaft position sensor pulse wheel and ensure that it does not bind when rotating the engine by hand. Last, replace the timing chain cover, reinstall all other components, refill the crankcase and other systems with relevant fluids, reconnect the battery, and start the engine with the lookout of leaks, so that the Powertrain Control Module can re-learn its idle and fuel trim strategy to achieve maximum performance.
