6g74 timing Change timing belt only problem with left bank timing mark is not clear. can someone tell me how many notch of timing belt between bank 1 to bank 2 timing marks

Hi!

The Mitsubishi Pajero with the 6G74 engine has different timing belt configurations depending on the year and model. According to the manufacturer's specifications, the 6G74 engine typically uses a timing belt with 259 teeth, but some models may use a timing belt with 265 teeth.
To determine the correct timing belt for your Pajero 6G74 engine, you need to check the owner's manual or service manual for the exact model and year of your vehicle. Alternatively, you can contact a Mitsubishi dealership or a qualified mechanic for assistance in determining the correct timing belt size.

If the belt that came off your engine has 259 teeth and the new belt in the kit has 265 teeth, it's possible that the incorrect belt was fitted. However, it's also possible that the previous owner or mechanic installed an aftermarket timing belt that doesn't match the manufacturer's specifications.
To verify that the correct timing belt has been installed, you can count the number of teeth on the old belt and compare it with the specifications in the owner's or service manual. You can also check for any markings or part numbers on the old belt to ensure that it matches the recommended part for your engine.

If you're unsure about the timing belt on your Pajero 6G74 engine, it's recommended to have it inspected by a qualified mechanic to ensure that it's the correct size and in good condition. A faulty or improperly installed timing belt can cause serious engine damage and should be addressed immediately.

Hope this will help you!

Kind regards

If it was running good before the water pump was removed, timing does not have to be reset.(timing belt didn't jump if it still runs normal) Change the timing belt & DONT turn either sprocket. Timing marks should be on both sprockets, To make it easier Mark both sprockets (put tape securely on both sprockets) with sharpie on tape to keep their position marked in alignment to any stationary point on the engine next to the sprockets. Sharpie won't show very well on bare engine metal.

looking from the front of the engine , the pulley mark on the LH cam pulley lines (12o'clock) up with the centre of the 2 notches and the RH lines up (12 o'clock) with the single notch. On the crank one mark will be lined up with a single notch at about the 1 o'clock position and another at the 3 o'clock position lined up with a series of dots. Ensure that you have the piston on TDC no1 first and align the crank marks first.

6 Cylinder petrol:
Align crank(C) timing notch mark (1) to oil pump mark.
Align cam pulley(L+R) marks(3) to cylinder head marks
The cam belt has 3 marks, 2 lines and one mark that is actually a row of dots. Align the dots to the crank pulley groove mark(2) and align the other 2 lines to the cam pulley marks. Using a clothes peg to hold the belt to the cam pulleys works wonders to keep it in place while fitting. Please note the arrows on the belt and have them point in the direction of rotation - right to left side of engine
W - water pump pulley
I - Idler pulley
T - Tensioner pulley.

If for some reason you need to realign the cams on each bank :
Standing in front of the car and starting from YOUR left , looking at the cams you should see RE, RI, LI, LE on each of the camshafts.(R for right bank, L for left bank, I for intake and E for exhaust) Right bank camshafts are marked with one dot, left bank with 2 dots on the shaft itself. To align the camshafts to each other each cam shaft gear has a mark on it. Draw an imaginary line between the centre of the camshaft and the centre of the pulley. The alignment mark should be between the two along this imaginary line. The result will be that RI an RE will be at the top of each gear. The same with the left bank.

10. Align the single timing mark on the left exhaust camshaft sprocket with the notch on the timing belt cover by turning the sprocket counter clockwise (viewed from front of engine).
11. Ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned when the single timing mark on the left exhaust camshaft sprocket is aligned with the notch on the timing belt cover. CAUTION
    • The camshafts can be rotated independently causing the valves heads to contact each other resulting in bent valve stems.
    • When the timing belt is removed the camshafts will turn to the lowest cam lobe position by the force of the valve springs. Before installing the timing belt the 4 camshafts are in the lowest lift position (valves closed).
    • When the camshafts are rotated to install the timing belts, # 2 intake and # 4 exhaust cam lobes of the left camshafts are held to push their corresponding valves down. In this position, these valves are held in the open position. Right camshafts are held so their cam lobes do not push the valves down.
    • The left camshafts must be rotated from the lowest lobe position to the position where the timing belt can be installed at the smallest possible angle in order to prevent intake and exhaust valve contact. Camshaft sprockets rotation
      
      
    • Do not turn the camshafts in the direction shown in the illustration because the valves will open at the same time and contact each other.
    CAUTION
    If the timing belt alignment is off the mark buy more than 3 teeth, the valves and pistons may have contact.
    Timing belt alignment marks DOHC

To align both sets of timing marks, turn engine crankshaft to the right with belt on cam and crank. Once you have done this the crankshaft alignment mark (on front of crankshaft gear) will line up with mark to the rear of gear on engine block.The two cam gear timing marks should be alines across from one another. The right cam gear is the intake side and the left side is the exhaust side. After removing the belt turn the exhaust cam down 1/2 notch. Timing mark on exhaust 1/2 notch down from the intake side. Install new belt and recheck everything to make sure it's all correct. Hope this will help you.

What are trying to do, change the belt or just set the timing? The timing marks should be on the left side (drivers side) near the front pulley. There is a notch or line on the pulley and the scale is on the timing cover. If you are trying to change the timing belt, you have to remove the fan and water pump pulley, then crank pulley and the timing cover. If you are changing the belt, here's a helpfull hint loosen the tensioner bolts, one 13mm one 17mm, then pull or push on the belt to force the ternsioner back as far as you can and tighten the 13mm bolt. Now you can take the old belt off and put the new belt on with ease. You have to set the crank at zero, I think the key in the crankshaft is straight up at this point, there is a diamond shaped mark on one of the teeth of the pulley, that lug has to line up with the notch in plastic behind the pulley. At this point you want the arrow on the cam pulley to point to the mark on the inner cover (about 6 o'clock) and the rotor in the distributor should point to the "V" notch in the pick up coil assembly (about 6 o'clock). Good luck!
