How do you put your 1992 2.4 Mitsubishi truck back on timing?

Answer 1

it mainly depends on which timing you are messing with.

if it needs timed because there is no power, you may want to adjust both.

if it needs timed because there is power, but no top speed, you may need to adjust the electrical timing.

there are two different timing settings for that vehicle. i have a 1993 Mitsubishi truck, and ive had to do both.

to adjust the electrical timing you will need:

a timing light

a 10mm ratchet, and/or box open end/box end wrench.

white chalk

to adjust it: *note* the electrical timing will not be correct if the timing belt is not in the right position, along with all of the timing marks. this is the other type of timing i will tell you how to adjust**

on the timing belt cover, there is a little notch with the number to written on it. you need to find it, and mark it with the white chalk. then, on the pulley for the crankshaft, which is the bottom pulley, there is a notch on there. you need to find it, and mark it with the white chalk. next, find the distributor cap. it should be a yellow color, at least mine is. its the thing with all of the spark plug wires coming off it. there is a bolt somewhere around there, that attaches to a small arm that holds the distributor in place. you need to find this bolt, mark its original position with the chalk, and then loosen it with the 10mm wrench. not too much though. break it loose, then only loosen it by one or two turns. the distributor should turn easily. hook up the timing light. ground the black clip on something metal, put the clip on the number 1 spark plug wire, in the middle of it, and connect the red clip to the positive battery stud. start the engine, (if its a manual, put it in neutral) make sure the back wheels are blocked, so it doesnt roll. aim the timing light down at the crankshaft pulley, the bottom one you marked with the white chalk, and pull the trigger to activate it. the two white lines you made should be lined up. if they are not, turn the distributor cap slightly, just not too much, until the two white chalk lines are matched up. when they are, very carefully, so as not to move the distributor, tighten the bolt, and make sure its solid tight. turn off the engine and disconnect the timing light.

to adjust the timing belt/replace timing belt you will need:

10mm socket and open end/box end wrench

a small cup to hold bolts

white chalk

an assortment of ratchets, and sockets

to adjust the timing belt/replace the timing belt:

*note* if you are replacing the timing belt, you may also want to replace the water pump at the same time. i replaced my timing belt without replacing the water pump, and two weeks later the water pump blew up.****

disconnect the positive batter cable. you may need to remove the radiator fan and top shroud. to do this there are 3-7 bolts to remove to take off the shroud. im not sure how many there are. just make sure you find them all and remove them all. take the shroud off, and set it aside. the alternator needs to be loosened to take off the belt. *note* if you have air conditioning, you will need to take off the air conditioning belt as well. if you only have one belt for all of the pulleys, there are 5 pulleys total, then just remove that belt.*** there is a bolt, most likely a 10mm, that needs to be loosened to move the alternator. don't pull the bolt out all the way, its not necessary, and swing the alternator towards the engine, to relieve the tension in the belt, and pull the belt off. swing the alternator back down to its original position. there are 4 bolts holding the radiator fan on. they are not 10mm, something smaller, maybe a 7 or 8. remove them all. throw the bolts in the cup. remove the fan, and set it aside. remove the pulley that it was attached to. now, there are bolts EVERYWHERE for the timing belt cover. i think total there should be around 15 or 20. i don't remember how many, but there is alot. for a few, you are going to have to crawl underneath the front end of the truck, but they are right there so you don't need to jack up the front end. the cover is in two separate pieces. the top piece MUST come off first. after you remove all of the bolts, place them in the cup so save them. remove the top cover. to remove you bottom, you need to remove the crankshaft pulley. its difficult to do however. you are going to need a breaker bar, and a really big socket. trial and error. keep trying different sizes until you find the one that fits. there is a very large stud in the middle of the pulley that you need to hold. that's what the breaker bar is for. you might be able to use a tire iron, the thing to pull the lug nuts off of the wheel. that may work. there are 4 bolts that need to be removed from inside the pulley. they are tight. you may need to use a 1/2" drive to pull them off. they are 10mm. hold the center piece still, otherwise you are going to turn the crankshaft, which you DO NOT want to do. it will make the timing more difficult to do. after the 4 bolts are removed, remove the pulley and set it aside. put the bolts in the cup. the center piece will not be removed. remove the bottom timing cover. *note* if you are replacing the timing belt, refer to the bottom of the page*** remove the timing belt, being very careful not to move any of the pulleys. note the timing marks. there is one on the camshaft, it looks like an imperfection in one of the teeth of the camshaft. the one to line it up with is on the left side of the engine, right on the corner of the block and the timing case. it looks like a VERY small triangle. the second timing mark is on the metal flange behind the crankshaft, and one on the crankshaft. then, to the right of the crankshaft, there is the third set of timing marks. one is on the sprocket, and one is on the bottom right corner of that pulley. all of the timing marks need to be aligned to their significant other. once that is acomplished, you need to put the new timing belt on. the pulleys are difficult to move, but they will move. DO NOT move them once they are in place. the tensioner for the timing belt will need to be adjusted. it must be loosened and swung toward the water pump ( to the left, on the passengers side of the vehicle). put the new timing belt on, being careful not to move anything. once it is in place, and fits snug into the teeth on the pulleys, swing the tensioner back toward the right, toward the distributor cap, and tighten until you are satisfied that the belt is tight. do not over tighten, but do not leave too much slack in the belt either. tight, but not too tight. re-install all of the necessary components.( the timing belt covers, crankshaft pulley, alternator and/or air conditioning belt, fan, shroud.) start the engine to make sure everything is set. the timing should be fine now, and the vehicle should run noticeably better.

****************ONLY READ THIS IF YOU NEED TO REPLACE THE WATER PUMP!!!!!***************

YOU WILL NEED TO DRAIN THE RADIATOR FIRST, if it looks ok you can reuse the fluid. put a bucket underneath the vehicle that the water pump can drain into, some of the fluid will come out of the engine.

after removing the timing belt, find all of the bolts for the water pump. remove them, and set them aside. should be 10mm. remove the pipe from the back of the water pump, and remove the water pump. be sure to remove the old "o"ring from the pipe. be sure to remove all of the old gasket from the engine. it should be completely smooth, nothing left over. apply the new gasket to the new water pump using gasket sealer, or shlack. that works really good. apply some of the sealer, or whatever you used, around the side of the gasket that will be against the engine. place the new "o" ring on the pipe, you may want to apply some sort of lubricant to it, it makes it easier to put the water pump on too. K-Y Jelly works good. place the new water pump on, careful not to let it touch anywhere except where it needs to. when it is the correct position, place the pipe into the back of the water pump. holding the pump there, put the bolts into their respective holes, but do not tighten them until they are all in and finger-tight. *note*refer to "replacing the timing belt" to put everything back together**** re-attach EVERYTHING. make sure nothing is left undone. put the radiator fluid back into the radiator, and start the engine. if necessary, add more fluid.

I hope that this helps, i know its alot to read, but it will get your baby running better. Good Luck!!!
