I have 2002 mish. montero sport,3.5,I'm need to reinstall timing belt.How do I set#1 on comp.stroke.Do I position crank sprocket timing mark about 1/4 before the embossed pointer for 5 degree TDC?

Did you install the belt with the number one piston on the compression stroke and have the distributor pointed at the number 1 plug connector wire. If so, you must of missed the belt placement by one tooth. If everything was correct like you mentioned it should of started. So, you made a small mistake that you will have to check again where, Im sorry :.(

Number 1 piston on the TDC of it's compression stroke, distributor pointed at the number 1 plug wire.
When on the compression stroke, the valve rockers on that piston will be relaxed (sealed) and the rockers will have play in them at that setting. Both rockers, intake and exhaust on number 1 will be loose when on the compression stroke of that piston.

With the head off, the bottom end doesn't know compression from exhaust from squat. The crank just keeps pushing the pistons up and down. You set the #1 cylinder at the top of travel, the mark on the pointer scale must be at zero, then when you have the head on with the camshaft sprocket on its mark, and the timing belt or chain on, you should be at TDC on the compression stroke. To verify, both valves on #1 should be closed-the camshaft lobes for #1 should be more or less pointing up-away from the valves.
See? The valve train is what determines compression stroke vs. exhaust stroke. On compression, both valves are closed. On the exhaust stroke, the exhaust valve will be open. As long as you get the camshaft sprocket on the right mark and the crank sprocket at zero-or on its mark-the timing should be right.

The compression stroke is relative to the head (actually the position of the valves), so TDC is all the same on the block, the lower end. Just line it up at TDC on #1.

Have you checked for bent valves or broken pistons? If the timing belt broke while it was running, and you have an interference engine, there could be damage from a piston touching a valve.
I don't know if that 2.4L engine is an interference motor. google it to find out. I don't think the position of any mark on the oil sprocket makes any difference.

On the Cam gear are three marks. On the face of the gear it should say "up", then you have three marks one at 3 o'clock one at 7 o'clock one at 9 o'clock. the one at 7 should align up with a mark on the block. Some have a raised semicircle and you line up the 7 o'clock mark on the cam with the far left hand end of that semicircle. Now on the crack end you have a mark at the 2 o'clock position and it lines up with a mark on the block. Do not turn the crank or the cam independent of one another, as the valves can be bent. Remove the spark plugs to ease turning the engine when needed. The engine will turn counterclockwise. Remove all necessary left hand front wheel, inner fender splash guard, covers, top engine mount. turn the engine until number 1 cyl. is at TDC compression stroke, and all timing marks align as noted. Remove the lower crankshaft bolt and pulley, and lower belt cover. Loosen tensioner bolt and push it out of your way and remove the belt. Put on the new timing belt in this order, crank sprocket, cam sprocket, water pump sprocket, tensioner. Belt must be tight on no tensioner side. Push the tensioner against the belt. Turn the engine 4 turns counterclockwise, until the timing marks realign, loosen the tensioner and turn the engine again 3 teeth, torque the tensioner to 30 flbs. reinstall all the mounts and covers. all should be good.

INSTALLATION
Install the idler pulley to water pump boss.
NOTE
Insert and install the idler pulley to the roll pin that is pressed in the water pump boss.


Install the tensioner arm and plain washer to the cylinder block.
Install the tensioner pulley to the tensioner arm.
Install the camshaft sprockets and align the timing marks.

NOTE
When installing the camshaft sprockets, fasten them tightly while holding the hexagonal part of the camshaft.
Before installing the timing belt, if the timing marks of the cam sprocket and the cylinder head cover do not coincide, do not rotate the cam sprocket more than 3 teeth in either direction.
Rotating the sprocket more than 3 teeth may allow the valve and piston to touch each other.
If the cam sprocket is rotated more than 3 teeth unavoidably, rotate the crankshaft counter - clock wise a bit before rotating the cam sprocket.
Install the auto tensioner to the front case.
NOTE
At this time auto tensioner's set pin should be compressed and secured with set pin.




Align the timing marks of each sprocket and install the timing belt in the following order. Crankshaft sprocket--> Idler pulley--> camshaft sprocket (LH side)--> Water pump pulley--> camshaft sprocket (RH side)--> Tensioner pulley.
NOTE
In this step, No. 1 cylinder is in the TDC (Compression stroke).
Be very careful if you use your fingers.



Pull out the set pin of the auto tensioner.



Install the upper and lower timing belt covers.
Install the power steering pump pulley, idler pulley, tensioner pulley and crankshaft pulley.
Using the wrench [16mm], rotate the tensioner arm clockwise (about 14°) and install the belt to the pulley.
Install the engine cover.
How to adjust the tension of the timing belt
Rotate the crankshaft 2 turns clockwise and measure the projected length of the auto tensioner at TDC (# 1 Compression stroke) after 5 minutes.
The projected length should be 6-8 mm.
Verify that the timing marks of each sprocket are in their specified position.
NOTE
If the timing marks are not in their specified position, repeat from 6 above.

3. Install the crankshaft sprocket.

Notice: Confirm if timing marks coincide with.

Image 7

Caution: Align the spacer with a pin, and assemble it exerting even force not to

deform the crankshaft sensing blade.

Image 8

4. Install the camshaft sprocket. Align it like initial state as shown.

Caution: When installing camshaft sprocket, tighten the bolt holding hexagonal

part of camshaft to prevent it from tuning.

5. Install the auto tensioner to the oil pump case.

Image 9

Caution: At this time the auto tensioner's set pin should be assembled completely.

Image 10

6. Align the timing marks of each sprocket and install the timing bell, maintaining the

proper belt tension between each shaft in this order. Crankshaft sprocket -> Idler

pulley -> Left bank exhaust camshaft sprocket -> Left bank intake camshaft sprocket

-> Water pump pulley -> Right bank intake camshaft sprocket -> Right bank exhaust

camshaft sprocket -> Tensioner pulley.

Caution:

1 As a result of this, position of No.1 cylinder comes to compression TDC.

2 As each camshaft sprocket tends to rotate by itself, pay attention not to injure

fingers or other bodily part. Especially be careful with the right bank.

3 In case the right bank camshaft sprocket rotates excessively, be cautious not to

rotate more than the initial stable position. Always align timing mark of rotating

sprocket by turning it reversely. In this case, pay attention not to rotate It

reversely from the initial position. (if. with one sprocket fixed at No.1

compression TDC position, the other sprocket is rotated one revolution

clockwise or counterclockwise, then the intake and exhaust valve might intetfere

each other)

7. After installing the timing bell, exert the reverse directed force to the right bank

exhaust camshaft sprocket to give tension on the belt. Holding this state, recheck it

each timing mark is correctly positioned.

S. With tensioner pulley slightly pushing the belt down, tighten the center bolt

slightly.

9. Pull out the auto tensioner set pin

How to adjust timing belt tension

1. Tension setting (While auto tensioner is not operating: And set pin being kept

installed.).

1) After rotating crankshaft 1/4 revolution reversely, rotate it clockwise to position

No.1 cylinder at TDC. Then, loosen the center bolt and give the belt 50 kg-cm of

tension with tensioner pulley socket (Two pins are attached) and torque wrench.

While maintaining this state, tighten the center bolt to the standard torque.

Center bolt standard torque 43 - 55 Nm (430 - 550 kg-cm, 31.72 - 40.57 ft. lbs.)

Image

2) Pull out the auto tensioner fixing pin.

2. How to check tension (While auto tensioner is operating: and fixing pin being

un-installed.)

1) After rotating crankshaft 2 revolutions clockwise to position No.1 cylinder at

TDC wait for about 5 minutes, and measure the amount of protruding of the auto

tensioner rod.

Caution: This is "leak down" time for the auto tensioner rod to protrude 1mm

when tension caused by rotation of the crankshaft has changed.

Image

2) Check if the amount of rod protruding is in the range of 3.8 -4.5 mm.

3. Recheck if each sprocket is within the specified range.

Notice: ¡fit is not within the specified range, repeat from procedure 6 as service

procedure of timing bell and auto tensioner installation method. Refer to Timing

Belt; Service and Repair.

The Isuzu is a strange animal-when you do the timing belt you set it with #1 TDC "BUT" the distributor is timed with TDC #4 I found this the hard way and finally had to buy a cd with the procedures on it. Send me an e-mail address and I will forward the associated pictures &
info to you.

TIMING BELT & SPROCKETS R & I
NOTE: Some procedures may differ slightly due to engine
construction.
Removal
1) Remove all necessary air ducts. Position No. 4 piston at
TDC of compression stroke. Align timing marks. See Fig. 2. Remove fan
and fan shroud. Remove belts. If necessary, remove radiator and
splashguard.
2) Prevent engine from rotating and remove crankshaft timing
pulley retaining bolt. Remove upper and lower timing belt covers.
Remove spring from tension pulley. Loosen adjusting bolt and move
pulley toward water pump. Remove timing belt.
CAUTION: Ensure pistons are at TDC when rotating camshaft or damage
may result.
Inspection
1) Handle timing belt carefully. Avoid twisting or kinking
belt. Do not allow belt to become contaminated by water, oil, dirt or
other contaminates. Inspect belt for cracks or damage. If necessary,
replace.
2) Measure tension pulley spring length and force. Spring
length should not exceed 2.76" (70.2 mm) and spring force should not
be less than 197-347 lbs. (27-48 kg).
3) Replace tension pulley spring if not within specification.
Installation
1) Pull tensioner fully toward water pump side and
temporarily tighten retaining bolt. Ensure No. 4 cylinder is at TDC on
compression stroke by rotating crankshaft until keyway aligns with
mark on front crankshaft seal housing (12 o’clock). Rotate camshaft
until timing mark on cam gear (arrow) aligns with mark on upper
camshaft cover (notch). See Fig. 2.
NOTE: When timing marks are aligned as stated above, No. 4 piston
is at TDC on compression stroke.
2) Position timing belt over crankshaft sprocket, oil pump
sprocket, camshaft sprocket and tensioner in that order. Ensure belt
is positioned in sequence given and without slack between sprockets.
Loosen tension sprocket adjusting bolt allowing spring tension to
tighten belt. Tighten adjusting bolt temporarily.
3) Temporarily install crankshaft pulley bolt and rotate
crankshaft 2 complete revolutions in opposite direction of engine
rotation, until marks on crankshaft and front oil seal retainer are
aligned again. See Fig. 2. Loosen tensioner lock bolt, allowing
tesioner spring to fully adjust tension. Tighten tensioner lock bolt.
4) Install timing belt covers. To complete installation,
reverse removal procedures. Tighten all bolts to specification. See
TORQUE SPECIFICATIONS table at end of this article.
