Sounds 180 degrees out. Move flywheel to top dead center. Remove timing belt and turn flywheel pulley ONE complete turn to top dead center. Then put timing belt back on with marks lined up.

What cylinder is used to reset distributor on 1994 Isuzu p.u. 2.3 engine


Unlike French cars which tend to use number four cylinder as the timing cylinder, almost everyone else including Isuzu use the traditional number one as the timing cylinder, not that for practical purposes it matters very much as it is a simple matter to discover which cylinder is at the top of the compression stroke and then fit the distributor with the rotor pointing at the distributor cap segment for that cylinder.

It is the direction of distributor rotation that confuses people more than anything as many rotate anti-clockwise although I believe the one you are working with rotates clockwise. Another problem with many traditional distributor installations is they often share the oil pump drive which must both be aligned before the distributor will successfully slide home and then because of the skew-type drive gear the distributor turns considerably on the way in and then the rotor is found to be misaligned. The apprentice mechanic soon learns to anticipate and allow for these things.

If the same distributor is being refitted it is best to make alignment marks to cut the amount of time and effort. Few engines require the removal of the distributor for routine timing belt replacement and usually all that is needed is an ignition timing check with a stroboscope.

How to timing the belt of isuzu 4jx1



stevenhurc_29.jpgbefore you remove belt time mark on cam gear as well as crankshaft pulley, the timming mark on the pump drive gear (lower gear in this picture) will not line up but thats ok line up the mark on pulley to rear cover at about 12 O clock when the belt is off.

Replacing the waterpump on a 1992 Isuzu pickup with carbureted, timing BELT 2.3 litre four cylinder engine. Do i need to remove the crankshaft-pulley center bolt to be able to pull the timing belt cover...


pretty safe on this old engine ,put socket and bar on the bottom pulley bolt and crank engine so starter motor cracks the bolt for you ,these older engines have a keyway on the pulley so no problem do not do this on new cars as pulley has no keyway and once the pressure is released the cambelt doesnt move and the valves go clonk

How do i put my 1994 v6 32-valve isuzu rodeo back in time


it would help if you gave an engine size but I'll guess its a 3.1 with a timing chain. there is a mark on the lower gear (crankshaft) which should be at 12 o clock position. on the camshaft there may be 2 marks 180 degrees apart from each other. number 1 cylinder is on the passenger side front, remove the distributor cap and align the ignition rotor to face where #1 spot on the distributor cap is by rotating the camshaft. this should put 1 of the marks at 12 o clock and 1 of the marks at 6 o clock. thats where you want the gears to be.

I have a 1988 toyota pickup with a 22re that i recently installed new and i cant get the timing right I jumped the right wires on the check connector and nothing happens I also reset the distributor


You need a diagram of the Distributor so you know where the Number 1 is at on the Distributor. You said you reset the Distributor and that is why you need that. You need to remove the distributor, re-align the cam so it is on teh number one compression, Both valves closed with the next cylinder in the firing order having the intake valve open and exhaust valve closed, and reset the #1 Piston to Top Dead Center on the compression stroke. Line the marks on the gears up and put the timing chain/belt back on. Reinstall the Distributor with the rotor position just before the Number one position on the Distributor. This should give you a good starting point that the engine will start from so you can adjust it the rest of the way. The best reference I can think of for all of this is the Haynes or Chilton's repair manual on your vehicle. They are available at most Auto Parts Stores. Good Luck.

Changing pickup coil


You have to remove the distributor from the engine then remove the distributor shaft from the distibutor housing, then you can remove & replace the pickup coil. Make sure you marke the exact location of the distributor body in relation to the intake manifold and note exactly where the rotor is pointing in relation to the distributor cap. I always set the timing marks on the front pulley at zero and make sure that the rotor is pointing at the #1 plug wire terminal on the cap before removing any distributor as it makes getting it in time easier if you lose your marks. You should reset the ignition timing when you have it all back together again as you'll most likely be off a few degrees. Some of these distributors had problems with the magnets in the distibutor shaft that would mimic a failing pickup coil and they were prone to drive gear wear. If you suspect any of those problems it's often easier to replace the entire distibutor with a reman unit.

I have a 22re jumped time put new timing chain gear on now will not idle


OKAY, THE BEST WAY TO NOT BEAT AROUND THE BUSH IS,
(1) REMOVE FRONT SPARK PLUG, STICK A SCREW DRIVER TO FIND THE EXACT TDC. (2) TIMING MARK ON CRANKSHAFT, MAKE SURE TS EXACT ON "0". IF THOSE TWO DONT SHOW ON THE EXACT MARK THE TIMING IF OFF.!!! THEN TAKE IT APART AND MAKE SURE THOSE TOW ARE ON THE DOT. -- TDC AND CRANK SHAFT "0" MARK.

When setting the timing gears, where do you set the distributor?


from memory no4 on dissy when timing marks on cam timing in correct position, no 1 cam lobes should be "rocking" and no4 cylinder should be at top dead firing stroke(ignition)should be notch in dissy when cap is off or set so rotor button is lined up with cyl no 4 ht lead position

1989 Isuzu pickup how to align timing marks on cam and crank?


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.
