need urgent help for timing belt lineup

[newbiescamry]

Hi guys..I very need the expert help for my timing belt adjustment...I followed the guides for my new timing belt replacement (my old belt was snap off)..I got the cam.pulley lineup at the dot..and cank.pulley at the "o" mark..put my new belt on..I gave it 2 turns (720') from the crank. pulley..everything look good..I started the car..it just cranking and cranking..I adjust the tooth one up..but nothing happen..anyway..I am doing something wrong? can someone guide me to adjust the belt from beginning? btw..this for camry le 4 cylinders..thanks

Hi, I followed this instruction..but still not able to start the car..
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>
1. Hole in cam gear lined up to the notch on bearing cap.

2. #1 at TDC. Notch on crank pulley lined up to "0" marking on lower timing belt cover.

Or mark/notch on oil pump pulley lined up to mark/notch on oil pump.

3. Install belt.

4. Tighten tensioner bolt.

5. Rotate crank clockwise 2 full turns (720 degrees).

6. Check alignment of cam and crank (See #1 and #2).

Did you have the crank pulley at TDC with the No 1 cylinder at TDC on the compression stroke? You could be 180 degress off on the crank.

The No 1 cylinder is closest to the cam pulley.

If you have done all of the above, and after 2 rotations CW of the crank the cam pulley is off. Readjust the pulley. As the belt slack is taken up the cam pulley can move a little bit

There should never be reason to need to have the crank/cam alignment NOT lined up as you stated. Never a need to have the cam pulley one tooth off to start the engine.

Hi..I am still lost..what do you mean the #1 engine at the DTC..I got the cam pulley line up what the notch...is that set the #1 engine to the DTC?

[newbiescamry]

also..I just found that there are two marks that the hole in the camshaft pulley can line up with. One looks like a line and the other is a circle. Which one are you supposed to use? also..do I need to refill the coolant before I start the car? or would the car start without the coolant for few seconds? I replaced the water pump..so the coolant totally empty...thanks

Aligning the crankshaft with its marks puts #1 piston at Top Dead Center (TDC). It becomes TDC Compression (TDCC) when you align the camshaft (valve position) to its mark.

The line.

I found that using a mirror made for a more accurate alignment as you need to look perpendicular into the hole. You will also need to allow for belt stretch when doing the alignment and may have to move the belt one notch so that after it's installed and tensioned all the timing marks line up.

also..do I need to refill the coolant before I start the car?

Not really for a quick start/stop, but you're not going to need to remove the water pump any more now, so I would just add the coolant. Make sure you get all the air out.

Hope you replaced the crank, cam and oil pump seals while you were in there.

thanks Stillrunning..I got all the seals and cam replaced..everything look good accept to put the timing belt in correct position..btw..I cann't seem to located the cam. sensor near the cam. pulley..according to the guides and pictures..the cam. sensor should be at that location..but I cant find it..this is a 1994 4cyl..all cars should have the cam. sensor rite? thanks

94' doesn't have a cam position sensor, only for the ones without dist., you have a distributor for cam signal.

N.E.O.

As NEO states you do not have a cam sensor.

Rotate the cam pulley until you can see the notch stamped at the top cam bearing cap trhough the pulley hole. Use a mirror as suggested by Stillrunning to see directly into the hole.

The crankshaft pulley is 1/2 the diameter of the camshaft pulley. The crank will turn 2 times for every 1 time of the cam. Thus is is possible when you have the crank pulley it TDC it can be 180 degrees off from where it should be.

You need to have the crank pulley mark at TDC with the No 1 piston (cylinder closest to the cam pulley) at TDC on the compression stroke.

If you have the valve cover off. Rotate the cam pulley CW until you see the intake valves close on the No 1 cylinder then continue until the pulley hole is aligned with the mark on the bearing cap. The intake valves are on the same side as the intake manifold.

thanks guys..I think I am 180 degrees off..because when the marks are lineup..I gave it 2 turns..the marks are in the same positions again..but car won't start..anyway..I will give the cank pulley 1 turn and reinstall belt..hope that will put it back the the TDC..will let you guys know later on today for the outcome..thanks

Yes two turns of the crank should put you with all marks aligned again. If that is what you have look for another cause for no start. You need both crank and cam marks aligned at TDCC for car to run.

[newbiescamry]

OK...I just turned the cank pulley 180 degrees..got the belt in..started the car..it sound like about to turnover but wont start..I adjusted 1 tooth back..same situation..it wont start..just crunching/shaking a little but wont turnover..I know I am very close..but somehow still cant get it rite..HELP!
thanks

The more you crank it the more fuel goes into the engine, you might have flood the engine with the cold start injector. Pull the distributor cap off to make sure the rotor is pointed to #1 cylinder when you time the cam. Pull the plugs out, pull the EFI fuse, crank the engine over. Put everything back together and see if it will start.

On the other hand, does 94' have a cold start injector on the 5sfe? Can't remember?

N.E.O.

Hi..I already got the plugs out..I will pull the EFI fuse..but can I cank the engine with the distributor cap on? or the distributor cap do need to come out in order to crank the engine? thanks
