OEM 2000 Toyota Echo Timing Chain

2000 Toyota Echo Parts Questions & Experts Answers

• Q: How to service and repair the timing chain on 2000 Toyota Echo?

  A: You must start the timing chain service and repair by draining engine coolant then removing the right-hand front wheel along with the engine under cover drive belt generator and PS pump from the engine. Support the engine using a jack before taking out the bolt fixing the liquid tube to the right-hand engine mounting insulator then detach the 5 bolts and nut as well as the insulator. The cylinder head cover needs removal following 4 nut detachment along with ignition coils and 2 PCV hoses and 7 bolts coupled to 2 seal washers and 2 nuts which also discard the cover and gasket. Locate the No.1 cylinder at TDC/compression by putting the crankshaft pulley timing mark "0" in perfect alignment with its groove while inspecting that the correct positions exist between the camshaft sprocket and valve timing controller. You can use Special Service Tool: 09213-70010, 09330-00021 to remove the crankshaft pulley and Special Service Tool: 09950-50012 (09951-05010, 09952-05010, 09953-05020, 09954-05020) will be required if additional assistance is needed. The experts should begin by unfastening all 13 bolts and the nut connected to these components using both a torx wrench socket (E8) for the stud bolt and hands for the remaining attachments before gently prying off the timing chain cover without causing any damage. Start by extracting both oil pan No.1 O-rings and the chain tensioner along with its slipper and vibration damper. The inspection should verify that the timing chain along with its sprockets shows no length beyond 123.2 mm (4.850 inch) and both the crankshaft and camshaft sprocket diameters must measure at least 96.2 mm (3.787 inch) and 50.5 mm (1.988 inch) respectively. The maximum dimension for the chain tensioner slipper and vibration damper wear should be 1.0 mm (0.039 inch). Check the chain tensioner plunger movement for smooth operation. The replacement of the crankshaft front oil seal requires trimming the existing seal lip before insertion of the new seal using Special Service Tool: 09612-22011 until it reaches the timing chain cover edge. To install the components position the crankshaft at ATDC 40 - 140 degrees then match the intake and exhaust sprockets to ATDC 20 degrees before resetting the crankshaft to ATDC 20 degrees. Put 2 bolts through the chain vibration damper at 9.0 Nm (92 kgf-cm, 80 inch lbs.) torques while setting the match marks of the timing chain and installing the chain tensioner slipper. When installing the tensioner operate the plunger to push the component while raising the lock plate and insert a 2.5 mm (0.098 inch) installation bar. Proceed to tighten the 2 mounting bolts to 9.0 Nm (92 kgf-cm, 80 inch lbs.). Resurface all contact points before adding Part No. 08826-00100 or equivalent seal packing to the timing chain cover. Then install together with the water pump followed by new O-rings through the use of 15 bolts and 3 nuts with torque values achieved through multiple sequential applications. The right-hand engine mounting bracket with seal packing (Part No. 08826-00080 or equivalent) should be mounted using 4 bolts which need to be tightened to 55 Nm (561 kgf-cm, 41 ft. lbs.). Then install the crankshaft position sensor and oil control valve followed by the crankshaft pulley according to specified torque values. The last step involves installing the cylinder head cover with fresh packing while connecting PCV hoses followed by the right-hand engine mounting insulator and PS pump and generator before adding a drive belt under the right-hand engine under cover and installing the right-hand front wheel and filling the system with engine coolant before starting the engine to detect any leaks.
