Refer to the procedure in this section. # Remove the three nuts and the engine support insulator through bolt from the engine support insulator. Remove the front engine support bracket (6028). # Raise and support the vehicle. # Align the crankshaft sprocket (6306) to TDC by turning the crankshaft (6303) in the direction of normal engine (6007) rotation. # NOTE: Remove the lower timing chain tensioner arm bolt before the upper timing chain tensioner arm bolt. Remove two bolts from the timing chain tensioner arm (6285) in the order shown. Remove the timing chain tensioner arm. # Mark the direction of rotation on the timing chain/belt (6268) to be sure of proper installation. # Loosen the timing chain/belt tensioner bolt. # Remove the timing chain/belt. Installation # Compress the timing chain tensioner arm until the hole in the piston is aligned with the second hole in the case. Insert a 1.6mm (0.06 inch) diameter wire or pin through the second hole to keep the piston compressed. # Align the camshafts (6250) to top dead center (TDC). # Turn the crankshaft clockwise until the crankshaft sprocket is offset from TDC by one tooth. # Install the timing chain/belt.Turn the crankshaft in the direction of normal engine rotation without moving the camshafts, until the crankshaft timing mark is again at TDC. This will place all of the belt slack in the timing chain tensioner arm portion of the timing chain/belt. # Install the timing chain tensioner arm and both bolts. Tighten the timing chain tensioner arm bolts to 19-25 Nm (14-18 lb-ft). # Remove the pin from the timing chain tensioner arm. # NOTE: When correctly timed, the crankshaft timing mark will line up and will NOT be one tooth off. Turn the crankshaft two complete revolutions, in the direction of normal engine rotation, to make sure that the timing is still correct. # Tighten the timing chain/belt tensioner bolt to 35-51 Nm (26-37 lb-ft). # Install the RH engine support insulator. Tighten the three nuts to 74-103 Nm (54-76 lb-ft) and the RH engine support insulator through bolt to 67-93 Nm (50-68 lb-ft). # Install the Engine Front Covers . |}
98's shold have a belt The Duratec V6 2.5L engine has two timing CHAINS. There are 2 timing chains which drive the 4 overhead camshafts. Hope this helps............
I have no idea how old this question is, but It sounds like you need a new timing chain. If, when you check the timing at idle and the timing mark on your dampner is wandering, then that's definitely the issue. Also, you can pull the distrubutor cap, turn the crank (19mm bolt center of crank pulley) and make sure the rotor is moving at the same time. If not, then that is a sure sign you have slack in your chain.
No, there is no American equivalent. 25 chain is smaller than T8F chain and 35 chain is larger. Ask me how I know... :(
To whom ever you are: :)) Timing chains, unlike timing belts, do not require regular interval replacement. The time chain is a life time part, (in most cases), in your case it is not under any warranty. The timing chain is oiled by splash from the oil pan itself. If you change your oil every 5000 miles or sooner, (I recommend 5000 miles, oil and filter), the timing chain will usually last the life of the vehicle. It is a VERY EXPENSIVE, replacement. I am a retired 25 year Toyota service manager .Very large service department and we probably dident replace 5 chains per year. We looked at over 2500 Toyotas a month. Hope this helped. Chuck
