- Remove the distributor gear bolt.
- Remove the rocker arm assembly.
- Rotate the crankshaft clockwise and set the engine to TDC/compression on No. 1 cylinder. Make sure the rockers for cylinder No. 1 are loose. If not, rotate the crankshaft one full turn.
- Matchmark and remove the timing belt from the camshaft pulley. Support the belt so that it doesn't change position on the crankshaft pulley.
- Loosen the camshaft bearing cap bolts a little at a time and in the reverse order of the installation sequence. After removal, label each cap.
- Remove the camshaft oil seal (at the pulley end) and then remove the camshaft by lifting it straight out of its bearings.
- Coat all the bearing journals with engine oil and place the camshaft in the cylinder head.
- Place bearing caps Nos. 2, 3 and 4 on each journal with the arrows pointing towards the front of the engine.
- Apply multi-purpose grease to the inside of the oil seal. and apply liquid sealer on the outer circumference of the oil seal.
- Install the seal in position, being very careful to get it straight. Do not allow the seal to cock or move out of place during installation.
- Install the bearing cap for bearing No.1 and apply sealant to the lower ends of the of the seal.
- Tighten each bearing cap little at a time and in the correct sequence. Tighten the bolts to 9 ft. lbs. (12 Nm).
- Hold the camshaft with an adjustable wrench and tighten the drive gear to 22 ft. lbs. (30 Nm).
- Install the timing belt.
- Install the rocker arm assembly.
- Install the fuel pump with a new gasket and connect the hoses.
- Replace the distributor and connect its vacuum hoses, electrical connections and the spark plug wires.
- Install the upper timing belt cover but don't install the bolt which holds both the upper and the lower covers yet.
- Connect the vacuum hoses.
- Connect the upper radiator hose to the water outlet.
- Install the water pump pulley and tighten the bolts finger tight.
- Install the power steering drive belt if so equipped.
- Elevate the vehicle and safely support it on jackstands.
- Install the bolt which connects the upper and lower timing belt covers.
- Install the power steering pump pivot bolt and the belt; adjust the belt tension.
- Lower the vehicle. Install the alternator belt and adjust it to the correct tension.
- Tighten the water pump pulley bolts.
- Refill the cooling system.
- Install the valve cover with a new gasket.
Toyota Tercel 1996
- Disconnect the negative battery cable from the battery. On vehicles equipped with an air bag, wait at least 90 seconds before proceeding.
- Remove the valve cover.
- Remove the timing belt assembly.
Remove the camshaft timing sprocket.
NOTEDue to the relatively small amount of camshaft thrust clearance, the camshaft must be kept level during removal. If the camshaft is not level on removal, the portion of the head receiving the thrust may crack or be damaged.
- Set the intake camshaft so the service bolt holes of the intake camshaft gears are directly up.
- Remove each front bearing cap of the intake and exhaust camshafts.
- Secure the intake camshaft sub-gear to the main gear with a 6mm diameter bolt, 16-20mm long and with a pitch of 1.0mm Make sure that the torsional spring force of the subgear has been eliminated by the above operation.
- In correct sequence, loosen and remove the 8 bolts of the 4 bearing caps of the exhaust camshaft and remove the exhaust camshaft. If the camshaft is not being lifted out straight, reinstall the middle bearing cap and loosen it evenly to keep the camshaft straight.
- In the reverse order of the installation sequence, loosen and remove the 8 bolts of the 4 bearing caps of the intake camshaft and remove the intake camshaft. If the camshaft is not being lifted out straight, reinstall the middle bearing cap and loosen it evenly to keep the camshaft straight.
- Using a small screwdriver and a magnetic finger, remove the adjusting shim.
- Install the valve shim to the engine.
- Apply engine oil to the surface of the intake camshaft.
- Place the intake camshaft on the cylinder head so the service bolt points directly up.
- Install the 4 rearward bearing caps in their original order and temporarily tighten them evenly. Do not torque the bolts at this time.
- Apply engine oil to the portion of the exhaust camshaft.
- Engage the exhaust camshaft gear to the intake camshaft gear by matching the proper timing marks on each gear.
Roll down the exhaust camshaft onto the bearing journals while engaging the gears with each other.
NOTEThere are other marks present for the "S'' engine. Do not use these marks.
- Install the 4 rearward intake bearing caps in their original order and tighten evenly. Do not torque the bolts at this time.
- Remove the service bolt.
- Clean the mating surfaces of the No. 2 bearing cap and apply sealer. Install and temporarily tighten the bolts. Install the camshaft housing plug.
- Now torque the intake camshaft cap bolts to 9 ft. lbs. (13 Nm), in the proper sequence.
- Apply grease to a new camshaft oil seal lip and install it as far as the deepest part of the cylinder head.
- Install the No. 1 bearing cap and temporarily tighten the bolts.
- Now torque the exhaust camshaft bearing cap bolts to 9 ft. lbs. (13 Nm) evenly and in the proper sequence.
- Turn the camshaft 1 revolution and check that the timing marks of the camshaft gears are aligned.
- Check and adjust the valve clearance. Install the valve cover.
- Install the camshaft timing sprocket and torque the bolt to 37 ft. lbs. (50 Nm).
- Install the timing belt. start the engine and check for leaks.
- Connect the negative battery cable to the battery.
