Timing chain installation


1996-1999 Toyota Corolla valve timing:
It is very easy to install the timing belt on 1997 Toyota Corolla. Do the following:
- Mark the numbers 1,2 and 3 on the spark plug wires with permanent marker or nail polish and remain the 4th one unmarked. This is necessary so that you can easily remember the spark plug wires order later on their original position.
- Remove the spark plugs so that the engine can easily be rotated.
- Rotate the crankshaft clockwise to align the v- groove mark on the crankshaft pulley with the 0 mark on the timing belt cover. If these marks are aligned the piston is always on the Top Dead Position (TDC).

- To replace the timing belt remove the crankshaft pulley, upper and lower timing covers.
- Temporarily screw in the crankshaft bolt in its place to rotate the crankshaft with the spanner and align the v- groove of lower crankshaft gear with the index mark on the oil pump cover as shown in the following diagram.
- Inspect the cam shaft mark through the small hole on the cam shaft sprocket. The punch mark should be exactly behind the hole on the cam shaft sprocket as shown in the following diagram.


25502648-okm0ksuj3f3lm2ubjq0dkjux-5-2.jpg
- Loosen the timing bearing bolt, press the bearing forcefully against the spring with some suitable tool and lock it there temporarily.
- Remove the timing belt.
- Remove the timing bearing.
- Replace the new timing belt and bearing with the original.
- Install in the reverse order of dis-assembly.
NOTE: NEVER PUT EXTRA FORCE ON TIMING BEARING TO ADJUST THE TIMING BELT TENSION. JUST LOOSEN THE TIMING BEARING BOLT AND THE SPRING ATTACHED TO IT WILL PULL THE BEARING IT SELF WITH THE PRESET TENSION TO ADJUST THE TIMING BELT.

Crank and flywhleel timing marks


You can find the timing mark on the end of a crank shaft by looking for an indented dot which marks top dead center.
A flywheel is balanced and does not need a mark. However if the wheel you refer to is a cam gear (one or two gears depending on how many cam shafts your engine has) look for 2 dots with a tooth grove between the two dots. A matching drive gear will have a single dot aligned with a tooth on the drive gear. When put together the single tooth marked on the drive gear must fall into the grove marked the the 2 dots on the cam gears.

If you are just trying to time an engine, the belt drive pulley mounted to the crank shaft will have a single indented line. The line can get filled with dirt so you can't see it. Wipe it clean and fill with grove with something to highlight the groove, as with a white or yellow crayon or a dob of bright paint. Associated with the belt drive pulley, there should be a metal plate with line marks spaced on it, with 0 degrees (top dead center TDC) marked on it, When the engine is running, using a strobe light connected to your number 1 spark plug you will see where the timing mark on the belt drive pulley is compared to the metal plate with the timing marks.

Blown timimng belt,how do i retime engine when replacing timing belt


Ok first thing is remove the #1 spark plug from engine, then turn your crank until you feel air push out that cylinder that means you are at TDC (top dead center). You will then set your cams to there settings ( I am not sure if this is a inline 4 or v6) so I can't tell you the marks. But the cams pulley will have marks that will align to marks on the head, The crank will have a mark on the pulley and on the block line these up as well. I like to set the top cam marks first then clamp the belt and pulley together with a small clamp to keep the tension. after that is all lined up install the tensioner and make sure you adjust the tensioner it will have two small pin holes that will need to be turned in order to tighten the tension. ( not to loose or belt can skip, not to tight or belt will wine.) Also if the belt snap while driving you probably bent the valves and will have to do a valve job which requires removing the head,

How do I know when my camshafts are top dead center the outter timing pulley was loosened stupidly before we could mark anything


Not to worry. The cam gear has marks on it already. When the cams are aligned at Top Dead Center (TDC) the keway for the pulley will be pointing UP and the marks on the edge of the pully will be lined up with the valve cover sealing surface of the cylinder hed. (See picture below)

How to set timing when you relesh tensioner and it changes the alignment postion of pullies 2000 ford ranger 2.5 l


Here is the trick. Align marks. Put the timing belt on the crank shaft pulley first, and after on the overhead cam pulley. Release tensioner and rotate the crank shaft till the timing belt makes two full circles. Try to align marks, you will be at least one tooth off. Align the crank shaft on the mark, and find out how many teeth you are off at the cam shaft pulley. Count the teeth. Remove the timing belt from cam shaft pulley only. Move cam shaft pulley in reverse according to the number of teeth you counted. Make sure the crank shaft pulley is on the mark. Mount the belt at cam shaft pulley.Rotate the belt two circles and check the marks. Repeate this procedure til after releasing the tensioner, and rotating the timing belt two full circles, the mars will be align.

How to replace a broken timing belt


Daewoo has interference engines in them, so if the timing belt broke while the engine was running, you will need to replace half of the valves which were bent when the pistons crashed into them when the cams stopped turning and the crank shaft continued to turn. Minimum of $700-1000.00 (usually more). If you do it all yourself and the valve guides are not damaged, still at least $400.00 worth of parts to fix. Pull plastic air dams around bottom of engine on front and right side . Support engine with jack. Drain antifreeze from engine and radiator. remove air filter housing and serpentine belt. remove front engine mount. remove cam belt cover. remove broken cam belt and check cam tensioner bearings and idler bearing as well. They are usually bad. Then remove spark plug cover. Remove valve cover. Remove intake from head. remove coil from head. remove heat shield from exhaust manifold then remove manifold from exhaust and from head. remove water hoses and connecting assemblies from side of head and rear of head. remove Cam shaft bearing caps loosening them all evenly so as not to bend cams. remove cams. remove head bolts. remove head. remove valve hydraulic lifters, compress valve springs and remove valve retainers and dissassemble valves. Clean everything very well. Make sure head is not damaged. Remove valve guide seals. install new valve guide seals, new valves. Seat valves with valve grinding compound. clean well. instal valves in reverse order of dissasembly. Before putting head on, make sure number 1 cylinder is at top dead center position. install head using proper torque of 18 ft # in a spiral application rotation from the center outward in a clockwise direction. Then do spiral rotation again tightening bolts each one-quarter turn. Repeat the tightening process two more times only turning the bolts one-quarter turn each time. Use new head bolts. They are designed to stretch in the process of installation and are not to be re-used. Align cams to proper orientation then bolt into place. do not overtorque cam bearing cap bolts. Less than 5 ft # of torque can stretch these bolts. Snug them then tighten them 90 degrees. Then tighten them another 90 degrees (quarter turn). Snug them all then go back and tighten all of them a quater turn, then go back and tighten all of them another quarter turn. Install the cam idler and tensioner and install the cam belt. then install the intake, exhaust and all other items in reverse order of assembly. Do not turn engine over unless you are sure you have the cam belt on with the crank shaft pulley aligned at top dead center and the intake and exhauste pulley marks aligned to their proper marks with the cam belt properly tensioned. You can't be even one tooth off. This must be right before you turn the engine over! Remove spark plugs and turn engine over by hand two rotation clockwise using a wrench on the center bolt of the crank shaft pulley. Check that the timing of cams is still perfect. If not, correct, retension cam belt, double check timing positions again then rotate engine two revolutions. Check cam timing positions again. The timing should not change! The engine should turn over relatively easily. If it feels like it doesn't want to turn, don't force it. You may have the timing off and be pressing a piston against a valve. If you are at this point, then you need to remove cam belt and unbolt cam shafts to release all tension on any of the valves. return the number one cylinder to top dead center position and then reinstall the cams and cam belt. Once it is assembled and in time, then reattatch the rest of the components that were removed in dissassembly. Do this in reverse order of dissassembly. then connect battery and fill radiator fluid. Start car.

Timing marks


this is a complex fix. if the timing belt is off, you will have to align both of the cams (V6??) to their respective notches on the back plate that protects the belt. You must also align the crank shaft to TDC, top dead center. Put the belt on (with tensioner off) then put tensioner on and release allen key. turn the engine by hand or using the starter two full rotations, the notches on the tops of the cam pulleys should be perfectly alligned with the notches on the back plate. if not, you missed a notch in the wrong spot and have to try again.

i've done this twice, once on a lexus es250 v6, and again on my 94 camry, its one of the hardest things i've ever done when repairing cars. be patient, have a friend help, don't get frustrated. if you really cant get it, have a mechanic come to your house and drop him a few bills to help you. you'll be glad you did

How to replace a timing belt


First take a digital picture of the belt while it is still installed, use that as a guide to install the new one, there are 2 marks that must be lined up, the crank pulley needs to be at #1 cylinder Top Dead Center (TDC) and the cam pulley arrow aligned with mark on head, make sure you check all the pulleys the belt runs on for loose bearings or roughness when the are spun, replace them as needed, now is a good time to do the water pump also. When you think every thing is right, turn the engine one revolution (by hand) and check the alignment marks again, if you get it wrong you can damage the valves, which is not good to say the least.
