TIMING ISSUE

1993 Mazda Protege

Engine Mechanical problem
1993 Mazda Protege 4 cyl Front Wheel Drive Manual 191000 miles

I have a 1993 protege, with 1.8 SOHC. I just replaced the oil pump. When I put the timing belt and cranshaft pully back on the engine, I set the camshaft timing marks to the 12 and 3 position. I also set the crankshaft pully to the timing mark at the 12 position with the mark on the block. Just like the haynes manual said. The issue now is I can't get it in time. It is timed TDC at the timing mark on the block and not the timing mark on the timing belt cover " T". I checked TDC on #1 and the crankshaft pully needs to rotate about a 1/8 of a turn clockwise to hit TDC. Should I taked the timing belt back off and rotate the crankshaft pully forward so the crank is TDC? The car currently runs, just idles rough and very low. I've tried adjusting the distributor but the timing mark will not come clockwise enough to hit the " T" on the cover.

As always your help is much appreciated.

Here is sprocket diagrams and install procedure

If removed, install the idler pulley and tighten the bolt to 38 ft. lbs. (52 Nm).
Install the tensioner and tensioner spring. Pry the tensione outward and temporarily tighten the tensioner lockbolt with the tensioner spring fully extended.

Pry the tensioner pulley (protect it with a rag) outward to fully extend the spring, then tighten the bolt to hold it in position

Make sure the crankshaft sprocket timing mark is aligned with the mark on the oil pump housing and the camshaft sprocket timing marks are aligned with the marks on the seal plate.
Install the timing belt so there is no looseness at the idler pulley side or between the camshaft sprockets. If reusing the old belt, make sure it is installed in the same direction of rotation.
On 1993-94 vehicles, temporarily install the pulley boss and lockbolt.
Turn the crankshaft 2 turns clockwise and align the crankshaft sprocket timing mark. On 1993-94 vehicles, face the pin on the pulley boss upright. Make sure the camshaft sprocket timing marks are aligned.
Turn the crankshaft 15/6 turns clockwise and align the crankshaft sprocket timing mark with the tension set mark for proper belt tension adjustment. On 1992-94 vehicles, remove the lockbolt and pulley boss.

To properly set tension on the belt, turn the crankshaft 15/6 turns and align the tension set mark with the crankshaft sprocket

Make sure the crankshaft sprocket timing mark is aligned with the tension set mark. Loosen the tensioner lockbolt and allow the spring to apply tension to the belt. Tighten the tensioner lockbolt to 38 ft. lbs. (52 Nm).
On 1993-94 vehicles, install the pulley boss and lockbolt.
Turn the crankshaft 2-1/6 turns clockwise and make sure the timing marks are correctly aligned.

Check the deflection of the timing belt to ensure proper tension has been set on the belt


http://www.2carpros.com/forum/automotive_pictures/52960_0900c152800397d0_1.jpg



Apply approximately 22 lbs. pressure to the timing belt at a point midway between the camshaft sprockets. The belt should deflect 0.35-0.45 in. (9.0-11.5mm).
On 1993-94 vehicles, hold the boss with a suitable tool and tighten the lockbolt to 123 ft. lbs. (21 Nm).
Install the timing belt covers and tighten the bolts to 95 inch lbs. (11 Nm).
Install the engine oil dipstick.
Install the spark plugs and connect the spark plug wires.
Install the timing belt inner guide plate, if equipped. Make sure the dished side of the plate faces away from the timing belt. Install the outer guide plate, if equipped.
Install the crankshaft pulley and tighten the bolts to 13 ft. lbs. (17 Nm).
Install the water pump pulley and the accessory drive belts. Adjust the belt tension.
Install the engine side or undercover, as necessary. Connect the negative battery cable.
Start the engine and check for proper operation. Check the ignition timing

I have the crankshaft sprocket lined up like the first picture, which is currently causing my problem. Mine is a SOHC engine. The diagram you provided is for a DOHC, I have the SOHC.
Thank you

I will send sohc install
12.Align the dowel on the camshaft with the dowel pin facing straight up. The dowel pin on the camshaft should also be facing upward.

13.Install the camshaft sprocket bolt. Hold the sprocket with the prybar and tighten the bolt(s) to 36-45 ft. lbs. (49-61 Nm).

14.Make sure the timing marks on the sprockets are properly aligned.

Fig. 4: When installing the belt, ensure that there is no looseness on the tension side of the belt

15.Install the timing belt tensioner and spring. Temporarily tighten the bolt with the spring fully extended.
16.Install the timing belt so there is no looseness on the tension side. If reusing the old timing belt, make sure it is reinstalled in the same direction of rotation.
17.Turn the crankshaft 2 turns clockwise and check the timing mark alignment. If the marks are not aligned, repeat Steps 11-14.
18.Loosen the tensioner lockbolt to set the tension, then torque the bolt to 19 ft. lbs. (25 Nm).
19.Turn the crankshaft 2 turns clockwise and check the alignment of the timing marks. If they are not aligned, repeat Steps 11-16.

Fig. 5: Check timing belt deflection by applying pressure at the point shown, and measuring the deflection

20.Apply approximately 22 lbs. pressure to the timing belt on the side opposite the tensioner, at a point midway between the sprockets. The belt should deflect 0.43-0.51 in. (11-13mm). If the tension is not as specified, repeat Steps 14-17 or, if necessary, replace the tensioner spring.
21.Install the spark plugs and connect the spark plug wires.
22.Install the upper and lower timing belt covers. Tighten the bolts to 95 inch lbs. (11 Nm).
23.Install the crankshaft pulley boss and tighten the lockbolt to 123 ft. lbs. (21 Nm), while holding the pulley boss with a suitable tool.
24.Install the crankshaft pulley and baffle plate.
25.Install the undercover or side cover. Connect the negative battery cable.
26.Start the engine and check for proper operation. Check the ignition timing.

After looking at the diagram, if I lined up the marks, but installed the belt incorrectly by failing to put the correct pressure on the belt as described during installation, could the camshaft slip off the marks?

Well, after following the diagram exactly, I still cannot get it to time to the timing marks on the timing cover. The car runs, idles and seems to have plenty of power. I can't get the timing mark to come to 10 degrees before top dead center. The timing notch in the crank puley lines up at 12 o'clock straight up when the timing light is on. When I double checked all of the marks on the crank and cam they are still lined up.

The car has about 80,000 miles on the last timing belt. COuld the belt be stretching? If I didn't put it back on in the same direction it was runing before would the belt be unusally loose. I've checked the rotor and it is lined up with #1 cylinder when the cylinder is at TDC.

Or should I not worry about it if it's running fine?

Thanks

Ok now when you put the belt back on as you look at the front of motor was the belt tight on the right side if so great you did it now how does it run smooth? Or still running rough I will still do some checking to see how to get the timing correct I have a friend at a mazda dealer thats were I got the diagrams for you so he'll help with this

I got it as tight as I could without causing the crankshaft sproket to turn and coming off my marks. I ran the car with the top ocver off and it looks like there is play in the belt, maybe that's an optical illusion from the flashlight.

My son drove the car this weekend and said the only thing he noticed was coming to a stop when the car would come to a very low idle the oil light would blink, like it does when it's about to die. Other than that ran ok.

Thanks for the continued help, I've heard these things can be tough to get in time.
