The procedure is given in the Hayes manual. You need to turn the cam shaft gear so that the front valves (two valves close to the gear point up) are close and the notch on the cam shaft other end is horizonal (side facing the battery). You need to bring the flywheel (in bellhousing) to top dead center (you will see a notch on flywheel and a fixed pointer on the bellhousing. The notch should be in line with the ponter. After that, you need to bring the injection pump at certain pisition. Then you can mount the belt. It is not a difficult process, I have been doing it, but you need certain tools that will make it easy, such as cam lock position tool, injection pump lock pin, gear remover, etc.

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 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.

I am planning on changing my water pump in my 86 Jetta diesel. I took a water pump off a 86 jetta (gas engine). I am having trouble getting to the top 2 bolts on the water pump. How can I get to those 2...


I dont think that you are installing the proper pump, you should really try using a new or remands water pump for a diesel, as the bolt patterns maybe different.

Where is the water pump on a Ford KJ Laser?


The water pump on the 92 Laser is easily replaced. You just need to untension the the belt driving the bump. Once you have done that all you need to do is undo the bolts and take the pump into your local auto parts dealer. Now that you have the pump install it and retension the belt.

U actually have to remove alternator belt and powersteering/a/c belts, then remove timing belt cover, remove timing belt adjuster, and slide timing belt off top pulley, making sure you mark it before removing it, so as to put it back in same position. Next, unbolt 2 bolts at bottom of water pump (this is a bit fiddly, but doable, then, undo water pump, replace with new water pump, being sure to use gasket cement, aswell as new gasket, which should be supplied with pump, then put it all back together, in reverse order of removal. Fill cooling system, check for leaks, and voila, u have done it :)

These engines are identified as an interference engine and on no account must the crank shaft and cam shaft be moved with the timing belt removed. You no not need to remove the water pump. You need to remove the water pump pulley only (not the water pump). I trust this helps.
