Question about 2006 Isuzu i-350
Cam markings left & right bank. position of tension gears on cam
why not read the book, read all steps.
and how to do it and not mess up.
its not trivial.
no year given... making it hard to look up, id have to look up all years... why do that to the helper??
is this a USA car? our books cover only it.
its a 3.5L not 350
DIY alldata.com is there, posted 100s times.
i post it for its the lowest cost, and instant access. no delays.
time is money right?
here is the discount link (USA spec.cars only)0
is this book not clear?
please ask questions or steps that are not clear.

It seems beyond belief that anyone would attempt this type of work without a basic shop manual. They are cheap, illustrated and include torque values needed to do this type of work.

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
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
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
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,
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.
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.

Yes be sure the number one piston is at TDC firing stroke or compresson stroke and line up the timing mark pointer is pointed at exactly zero. One more thing when aligning the camshaft sprocket or sprockets be sure that when you are rotating the sprocket for the cam it is rotating in the correct direction and also be sure you observe the intake valve for number one shutting as you bring the marks up to alignment points, the intake valve and the exhaust valve should be shut when the marks line up if not you could have the cam sprocket off 180 degrees, get it right the first time or you may damage a valve trying to start.

Actually, honeymonkey, the camshaft pulley turns exactly once for every two revolutions of the crankshaft. (pretty sure that was just a mental juxtaposition on your part) That is how you get a 4 stroke engine: the piston has to go up and down twice to complete one power cycle.
Now, as for aligning the engine: This is fairly straightforward. All you need to do is to set the cam marks and crank marks to #1 top dead center. The crankshaft position can be verified with a straw or something inserted into the #1 spark plug hole and turning the engine slowly with a wrench. The camshaft position can be verified by removing the distributor cap and making sure the rotor is pointed to the #1 spark plug position AND the marks are lined up at 0 degrees TDC. If the chain or belt is off by 1 tooth the motor will not likely start, so don't spend a bunch of time getting it exactly on the line. If the marks are close enough to get the chain or belt on, it is probably right. You may need to loosen the distributor and turn it forward or back A LITTLE to get 'er started, but DO NOT do this until you are satisfied the cam and crank are timed OK. It is your only reference mark for static cam position. The motor will sound funny when cranking if the cam timing is off. Good Luck!

Timing Belt Service 2002 Kia Sedona 3.5 liter
1. Remove the engine cover
2. Remove the drive bell.
3. Remove the idler pulley, crankshaft pulley, power
steering pulley and tensioner
4. Remove the upper and lower timing belt cover.
5. Support the engine with garage jack or special tool, and
then remove the engine
Caution: Take care not to deform the engine oil pan.
6. Remove the auto tensioner.
Notice: Rotate the crankshaft clockwise and align the timing
