SOURCE: alternator belt diagram 1992 Isuzu trooper

1. Remove battery terminals and secure them away from the battery posts using nylon wire ties.

1a. Fine some comfortable eye glasses (clear or yellow) and keep them on. There are plenty of opportunities to get debris in your eyes during this procedure.

2. Spray "PB Blaster" (loosens bolts) on two bolts that secures alternator.

3. Jack-up vehicle on side to access alternator. Use a jackstand to support.

4. Using a 10mm open-ended wrench, loosen the bolt that swings the alternator. Screwing the bolt "in" or toward the engine will allow play to increase in the alternator belt. Loosen the 12mm bolt slightly next to the 10mm bolt (approximately 1.5" toward engine).

5. Continue to loosen 10mm bolt until there is enough slack in the belt to remove the belt from the alternator pulley.

6. Remove belt. It may be possible to remove belt without removing fan faring. Maybe not. If not, you will need to remove plastic fairing. If you must remove fair, go below fan fairing and disassemble connectors that hold together pieces of fan fairing. Carefully remove.

7. Install alternator fan from above.

8. Check that alternator belt is on all tracks (from below with a flashlight), and slowly tighten.

9. Secure 10mm and 12mm bolts. Recheck tightness.

10. Reassemble battery connection and run vehicle at idle for about 5 minutes. Check belt for proper tension.

11. CAREFULLY check tension of belt. Or disassemble battery connections and re-check belt tension.

12. Reassemble fan fairing (if not already assembled), re-connect battery terminals, and have a nice day. :-)

SOURCE: isuzu trooper problem!with a 00 3 litre diesel engine not starting

Was it lined up right as the trigger point for the sensor is important.Is the fly wheel fitted one position only that the bolt holes line up or will it fit no matter which position it bolts up Line up the flywheel trigger with the sensor after you have put the engine to Top Dead Centre.Put at tdc and see if the trigger and sensor are together.

SOURCE: Fitting 3.1ltr diesel engine to Isuzu Trooper

Be careful............if the engine you want to fit is made by VM, these have individual cylinder heads. In Europe they have given  a heap of trouble and have to be replaced when they overheat.
If you have a friend who speaks Spanish, get him/her to surf  the net and have him/her translate some of the stuff I've read about here in Spain.
I am looking for a Grand Cherokee and have been advised to look for the 2.7 model engine which is a derivative of the older Mercedes engine.........they last forever and spares are easy to get.

How to fix an injector pump of 4jx1 engine


this is a USA forum what country are you in?
Fuel systems vary by engine, and country, so......?????
what needs fix'n?

the word fix has many meanings
  • how to rebuild the pump?
  • time it?
  • how to remove it put back?
  • how to bleed it.
  • and on and on... or a lift pump or ?
try to say what you are doing "the job" and why,
or if not a job, must be diagnosing it, ?
say , im trying to test it or. what ever you doing.
we cant guess, what fix means.
Diagnosing direct injection?



The 4JX1 is a 3.0 L direct injection diesel engine, turbo, some intercooled, which replaced the 4JG2 in the Isuzu Bighorn/Trooper/Holden Jackaroo.
It uses unit injectors and 4 valves per cylinder.

European and Asian buyers could opt for the diesel.

see we dont have this.
troopers are sold in Asia too, but not here with diesel.

Timing marks trooper 1985 mod dlx turbo diesel


Refer to Figures 1,2,3,4 when performing 17-step timing procedure for 1981-1985 Diesel Engines.

Fig 1. Injection pump and camshaft alignment marks - Diesel engine.

Fig 2. Removing the timing belt holder - Diesel engine.

Fig 3. Injection pump alignment marks - Diesel engine.

Fig 4. Tensioiner Pulley Bolt Sequence - Diesel engine.

Procedure - Timing Belt replacement.

1. Disconnect the negative battery cable. Drain the cooling system.

CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

2. Remove the timing belt cover. Remove the injection pump sprocket flange.

3. Using a prybar, remove the tension spring from the timing belt tensioner.

When removing the tension spring, avoid using excessive force for the spring may become distorted.

4. Remove the tensioner pulley bolt and the pulley.

5. Remove the timing belt and discard it.

To install:

6. Rotate the crankshaft to bring the No. 1 piston to TDC of the compression stroke.

7. Align the timing marks on the injection pump sprocket with the camshaft sprocket; the marks must be facing each other.

8. Using a new timing belt, install it in the following sequence: crankshaft sprocket, camshaft sprocket and the injection pump sprocket; the slack must be between the injection pump and camshaft sprockets.

9. Install the tension center and the tension pulley so the end of the tension center is fitted against both pins on the timing pulley housing.

10. Hand tighten the nut so the tension pulley can be rotated freely.

11. Install the tension spring and semi-tighten the pulley nut to 22-36 ft. lbs. (30-48 Nm).

12. Rotate the crankshaft 2 full turns clockwise to seat the belt and further turn the crankshaft 90° beyond TDC to settle the injection pump.

13. Loosen the tension pulley nut to take up the timing belt slack. Tighten the tension pulley nut to 79-94 ft. lbs. (108-128 Nm).

14. Install the injection pump sprocket flange; the hole in the outer circumference of the flange should be aligned with the triangular timing mark on the injection pump sprocket.

15. Rotate the crankshaft 2 full turns clockwise to bring the No. 1 piston to TDC of the compression stroke. Make sure the triangular timing mark on the timing sprocket is aligned with the hole in the flange, then, measure the timing belt tension; it should be 33-55 lbs.

16. Install the timing belt cover.

17. Connect the negative battery cable.

Yes you can . Requires some skills but the only bits that dont work after are the speedo and the rev counter .

Do i need a turbo timer for an intercooled diesel engin..isuzu...


Yes it pays to have a Turbo timer or let it run for 3 minutes after an outing.
An Intercooler is usually fitted to turbo charged engines.It cools the air entering the engine making it denser,Thats why cars go really well on frosty mornings after they reach running temp.
Hope this helps.

You must have #1 on TDC and the camshafts on the timing mark to fit a new belt , I rekon yer valves are fouling the piston .
Ignore the mark on the pump pulley .
