Mitsi Montera/Pajero/Magna 2.6 timing chain tension

My 2.6 Astron (in a '92 Pajero) appears not to have the usual tension adjuster. According to my Haynes manual it shoud have a ''special bolt B'' I undo and then push the adjuster to tension, then tighten the B again. Instead I see just a single pozidrive/philips screw head.

Could this mean I have a hydraulic adjuster as per later Magnas? Any guide to what I need to do to adjust this?

Kind regards

The 'special bolt B' listed in the Haynes manual allows adjustment for the silent shaft chain, not the timing chain.
I don't know why there is a phillip head screw instead of a bolt.

How to stop timing chain rattle

Timing chain rattle is usually a result of a worn out or broken chain tensioner, although extremely high mileage can cause gear wear to cause it. Replacement of the timing set, to include the tensioner will certainly solve the problem. (Some engines have adjustable chain tension... you might investigate this as well).

How to replace fan belt on a Mitsubishi pajero

  1. 1 Open the bonnet of the Pajero, and turn the bolt on the centre of the tension pulley with a socket wrench two full rotations. The tension pulley is the pulley directly behind the fan in the upper portion of the front of the engine.
  2. 2 Loosen the adjuster bolt on the tension pulley bracket. This bolt is on the left-hand side, situated in a long horizontal groove.
  3. 3 Slip the fan belt off of the engine. Draw a diagram of the path of the fan belt if the factory printed sticker diagram is no longer in the front of your engine on your Pajero.
  4. 4 Insert the new fan belt, winding it through the various pulleys according to your diagram. Put it on the tensioner pulley last.
  5. 5 Place the tension belt tool on the tension pulley bolt and pull until the slack in the belt is gone. When there is no slack, keep the pressure on the pulley, and tighten the adjuster bolt with the wrench. Tighten the lock bolt on the pulley.

Timing chain replacement

Timing Chain and Gears REMOVAL & INSTALLATION 1.9L Engine NOTE: The following procedure requires the use of the puller tool No. J-25031 or equivalent, and timing sprocket installation tool No. J-26587 or equivalent.
  1. Remove the timing (front) cover from the engine.
  2. Lock the shoe on the automatic adjuster in fully retracted position by depressing the adjuster lock lever. NOTE: To remove the timing chain, it may be necessary to remove the camshaft sprocket. Before removing the timing chain, be sure to align the timing marks.
  3. Remove timing chain from crankshaft sprocket.
  4. Check the timing sprockets for wear or damage. If crankshaft sprocket must be replaced, remove the sprocket and the pinion gear from crankshaft using the puller tool No. J-25031 or equivalent.
  5. Check timing chain for wear or damage; replace as necessary. Measure distance "L'' (40 links) with the chain stretched with a pull of approximately 22 lbs. (98N). Standard "L'' value is 15 in. (381mm); replace chain if "L'' is greater than 15.16 in. (385mm).
  6. Remove the automatic chain adjuster-to-engine bolt and the adjuster.
  7. To check the operation of the automatic chain adjuster, push the shoe inwards, if it becomes locked, the adjuster is working properly. The adjuster assembly must be replaced if rack teeth are found to be worn excessively.
  8. To remove the chain tensioner, remove the "E'' clip and the tensioner. Check the tensioner for wear or damage; if necessary, replace it. Fig. 1: Timing chain guide and tensioner - 1.9L engine 85383285.gif

  9. Inspect the tensioner pin for wear or damage. If replacement is necessary, remove the pin from the cylinder block using a pair of locking pliers. Lubricate the NEW pin tensioner with clean engine oil. Start the pin into block, then place the tensioner over the appropriate pin. Position the E-clip onto the pin, then (using a hammer) tap it into the block until clip just clears tensioner. Check the tensioner and adjuster for freedom of rotation on the pins.
  10. Inspect the guide for wear or damage and plugged lower oil jet. If replacement or cleaning is necessary, remove the guide bolts, the guide and the oil jet. Install a new guide and upper attaching bolt. Install the lower oil jet and bolt, so that the oil port is pointed toward crankshaft. To install: Fig. 2: Timing chain alignment and installation - 1.9L engine 85383286.gif
    Fig. 3: Inspecting the timing chain for wear 85383287.gif

  11. Install the timing sprocket and the pinion gear (groove-side toward the front cover). Align the key groove with crankshaft key, then drive it into position using installation tool No. J-26587 or equivalent.
  12. Turn the crankshaft so that key is turned toward the cylinder head-side (No. 1 and No. 4 pistons at TDC).
  13. Install the timing chain, align the timing chain mark plate with the mark on the crankshaft timing sprocket. The side of the chain with the mark plate is on the front-side and the side of chain with the most links between mark plates is on the chain guide-side. Keep the timing chain engaged with the camshaft timing sprocket until the camshaft timing sprocket is installed on the camshaft.
  14. Install the camshaft timing sprocket so that it's marked-side faces forward and it's triangular mark aligns with the chain mark plate.
  15. Install the automatic chain adjuster.
  16. Release the lock by depressing the shoe on adjuster by hand, and check to make certain the chain is properly tensioned when the lock is released.
  17. Install the timing cover assembly.

Would my timing chain on a 92 4cyl magna have an adjustable timing chain

no, once the chain is set there is no way to change it, unless you take it off and install a new one.The timing chain has tensioners that keep the tension by itself.I hope I could help rate me accordingly, Thanks!!

I have a Mitsubishi Pajero NM 2002 3.2lt diesel timing chain

I checked out the pajero forum, they don't mention the bottom tensioner as being the noise maker here but rather a sloppy chain, stretched beyond the tensioner and riding on the guides. The noise sounds like it comes from the fan area as a metallic chattering. They sell a chain that has a master link in it, and you don't have to tear down the entire engine again to get to it, just the top cover,, Cut the old chain, and use it to pull the new one through. Also, if your chain did jump its gear, it would only be a matter of 8 - 10 miles before the cam breaks. Hope this helps.

No, timing chains are not expected to be replaced periodically like belts. Ocassionally they get noisey at high mileages and require a new tensioner pad but usually the chain is OK with a new pad
