Tensioner, Driver Side

Begin the replacement procedure of the Timing Chain Tensioner by removing the engine front cover. Stage 2 marks should be placed on Timing Chain and sprockets when the entire camshaft timing system remains outside stage 2 to enable correct reassembly. The next operation demands removal of the Timing Chain Tensioner. Put in the new Timing Chain Tensioner before adding the engine front cover into its position.

To replace the right side timing chain tensioner, remove the engine front cover first. Then, remove the right bank-timing chain tensioner. Then, install the new right bank timing chain tensioner and final reinstall the engine front cover. Adhere to the right tools in accordance with each procedure to ensure that everything is installed and functioning correctly.

To remove the Timing Chain Tensioner, you need to unplug the negative Battery Cable first. Nextinkle the camshaft cover out then the Timing Chain Tensioner out with the seal out of the tensioner. Check for damage on the Timing Chain Tensioner, o-ring seal and washer; replace them as necessary. Measure the Timing Chain Tensioner assembly starting from one end to the other; a new tensioner in the fully compressed non-active form will be 72 mm (2.83 in) or an active state of 85mm (3.35 in) should be supplied. If the Timing Chain Tensioner is not in the compressed state, remove the Piston assembly, from tensioner body, install the j 45027-2 into a vise, insert the notch end of the Piston assembly into j 45027-2 and use j 45027-1 to turn the ratchet cylinder into the Piston. Even the tensioner body bore must be inspected for dirt, debris, and damage; however, polish it with a lint-free cloth if necessary. Return the compressed Piston assembly into the Timing Chain Tensioner body until it drops to the bottom of the bore without being compressed towards the bottom. The tensioner should be about 72 mm (2.83 in). If not, go through the previous steps again. Get rid of every dirt and debris from the area in the cylinder head where the Timing Chain Tensioner is threaded, and ensure that the seal of the timing chain during the process of tightening ensures the seal is centered so as to avoid oil from leaking out. Install the Timing Chain Tensioner assembly and tighten it 75 nm (55 lb ft). Use a suitable tool with a rubber tip to, compress the Timing Chain Tensioner 2mm (0.079 in), pare it to rest over the cam chain, working the tool down from the cam drive chest, then apply a sharp jolt diagonally downwards to release the Timing Chain Tensioner. Finally, replace the camshaft cover and replace the negative Battery Cable as well.

The replacement of timing chain tensioners starts with removing the negative Battery Cable. Begin by taking off the camshaft cover then the Timing Chain Tensioner before removing the tensioner's seal. Check the Timing Chain Tensioner along with its o-ring seal and washer for damage. Replace them as necessary. Check the length of the Timing Chain Tensioner assembly between both points. The tensioner system demands new components at their fully compressed non-active state which should measure 72 mm (2.83 in) (a) when compressed and 85 mm (3.35 in) (a) when active. To measure the compressed state of the Timing Chain Tensioner begin by removing its Piston assembly from the tensioner body then position the j 45027-2 into a vise and place the notched Piston end into the j 45027-2 . The operation of the ratchet cylinder into the Piston requires a j 45027-1 tool. Detach the tensioner body to inspect inside the bore for contamination and structural destruction. Clean it with a lint-free material if needed. A lint-free cloth helps clean the surface when needed. Place the compressed Piston assembly into the Timing Chain Tensioner body so it reaches the bore's lowest point but avoids touching the bottom. The tensioner should reach a length of 72 mm (2.83 in) (a) between both ends. Do the previous procedures again if the measurement does not match the specifications. Thoroughly remove all dirt and debris from the threaded hole in the cylinder head which receives the Timing Chain Tensioner. The torque procedure requires proper placement of the Timing Chain Tensioner seal to stop oil leakage. Put the Timing Chain Tensioner assembly into place then tighten it to 75 n.m (55 lb ft). Apply force to the tensioner while it is compressed by 2 mm (0.079 in) to unlock its locking mechanism. A suitable tool with a rubber tip should deliver a sharp jolt that goes diagonally downwards through the cam drive chest to disengage the tensioner. The process ends with reinstalling of the camshaft cover followed by reconnecting the negative Battery Cable.

First disconnect the negative Battery Cable, in order to change the Timing Chain Tensioner. Next proceed to remove the camshaft cover and then remove the Timing Chain Tensioner, followed by the seal from the tensioner. Check the damaged Timing Chain Tensioner. If the tensioner, o-ring seal, or washer is damaged, replace them if necessary. Measure the Timing Chain Tensioner assembly from end to end; a new tensioner should be supplied in a fully compressed non-active state = 72 mm (2.83 in) and an active state tensioner = 85 mm (3.35 in). When the tensioner is not in the compressed state, take the Piston assembly out of the body and secure it in a vise, then turn in the notch end of the Piston assembly into the vise and use a suitable tool to turn the ratchet cylinder to the Piston. Clean the bore of the tensioner body of dirt or damage with a lint-free cloth, removing any debris. Install the compressed Piston assembly into the Timing Chain Tensioner body without compressing it to the bottom of the bore and making it roughly 72 mm (2.83 in) in overall length from end to end; if not, continue the previous steps. Make sure all particles of dirt and debris are eliminated from the Timing Chain Tensioner threaded hole in the Cylinder Head, and place the Timing Chain Tensioner assembly, and tighten up to 75 Nm (55 lb ft). Release the Timing Chain Tensioner by compressing it 2 mm (0.079 in) with the help of a suitable tool with a rubber tip applying a sharp diagonal (downwards) jolt. Finally, mount the camshaft cover and reconnect the negative battery.

Start the replacement process of the Timing Chain Tensioner by disconnecting the negative Battery Cable first. The installation process begins with the camshaft cover and then moves to the Timing Chain Tensioner before sealing the tensioner. Inspect the Timing Chain Tensioner for damage then replace the tensioner with new parts when needed. Measure the length of the Timing Chain Tensioner assembly before purchase. The replacement tensioner must arrive in the compressed non-active state with dimensions of 72 mm (2.83 in) from end to end but will extend to 85 mm (3.35 in) when active. When the tensioner exists in an uncompressed state attach the en-45027-2 (tool) to a vise before inserting the Piston assembly notch end into the tool. The en-45027-1 (tool) rotates the ratchet cylinder into the Piston position. Check the tensioner body bore for signs of dirt as well as damage and debris. Replace the tensioner with a new one after cleaning it with a lint-free cloth when you detect damage. Reposition the compressed Piston assembly inside the Timing Chain Tensioner body to reach its stopping point at the bottom of the bore without forcing it against the bottom surface. A proper tensioner length should be 72 mm (2.83 in) when the tool measures end to end. Every time measurements deviate from specifications repeat all preceding installation steps. All debris and dirt must be cleaned out of the Timing Chain Tensioner threaded hole which penetrates through the cylinder head. Secure the Timing Chain Tensioner assembly with 75 nm (55 lb ft) torque. The Timing Chain Tensioner requires a suitable compression tool with a rubber tip to lower 2 mm (0.079 in) before administering a diagonal downwards jolt through the cam drive chest until the tool rests on the cam chain. Next install the camshaft cover followed by reattaching the negative Battery Cable.
