MudisFun Posted March 8, 2005 Share Posted March 8, 2005 I was looking through the R&M section and noticed that it has grown since I have joined. But still not what it could be! I know that there have been a few long, long, long how-to posts for the old gen that would be good to "buff up" and save as for reference and instuction. I think it would be smart to have well spoken people avalible to review and revise members how-to's. I heard the r&m section use to be filled but almost not worth the effort to fing the right info? Maybe if all posts in the r&m could be ungraded, corrected, and added upon BY ANYONE then there would one kick rump roast write up for one repair or mod. Here's something that I posted a while back, torxxx has a good EA82 Disty instruction but I think maybe a few ideas were left out; although calbrez might say different. Still I know somebody has something to still add (torxxx , your .02 would help) before she's ready to go! 1. Crank the engine untill the first cylinder reaches Top Dead Center. Remove the spark plug from the cylinder closes to the electric fan, this is #1. Pull the rubber cover off of the bell housing so that you are able to read the numbers of advanced and retarded timing. Rotate the crank shaft by using a box wrench on the acorn type nut holding the pulley down. Stick your finger over the plug hole. You are feeling for the compression stroke, that is when the piston reaches TDC and declines to BDC without either valve opening. So when you feel air pushing from the combustion chamber (cylinder), that is when the piston is compressing the air/gas mixture. If the the crank is rotated a few more degrees (15 or somthing) the flow will change and the piston will try to suck you finger into the chamber. When moving beyond the compression stroke you are simulating the power, downward force, provided by the mixture being ignited by the spark plug. Find the spot between the two strokes and that is TDC. Now look at the flywheel or flex plate and line up the marker with the degrees BTDC indecated by your manual or 20 B, your almost done! 2. Set the distributor. Most manuals will describe a system using two arrows... it's confusing. With the disty dis-engauged from the drive gear on the cam shaft, remove the disty cap. Rotate the shaft by turning the ignition rotor (the plastic cap with a strip of metal on the top). Since the engine is at the point which it requires a spark at the first cylinder, the rotor should be over the right over the first cylinder's spark plug wire on the disty cap. At this point you might see where the arrow system works. Set the disty into the cam, locking the gears. Check the cap one more time to make sure that the rotor is where it should be. This might take a few tries. 3. Fire her up! Replace the spark plug, cap, wire, and vac advance lines. Make sure everything is ready and then fire her up, if she will. If nothing happens but the starter cranking, that's bad. If the engine starts and sounds like crap, good. Play with the timing untill it will hold a spark so you can run to the timing gun. Don't pull out the disty from the cam until you have run out off of space but keep in mind that most likely if you did step 1 & 2 correctly it's all good but might need a second person so you a examine the timing light while someone rotates the crank using the starter.

MudisFun Posted March 9, 2005 Author Share Posted March 9, 2005 bump? No, yah's lets getting crack'in on that section? Nobody have any ideas to prefect the disty service write-up? Link to comment Share on other sites More sharing options...

MudisFun Posted March 9, 2005 Author Share Posted March 9, 2005 1. Crank the engine untill the first cylinder reaches Top Dead Center. Remove the spark plug from the cylinder closes to the electric fan, furthest from the disty, this is #1. Pull the rubber cover off of the bell housing; located on top of the EA82's and side of the EA81's, so that you are able to read the numbers of advanced and retarded timing. Rotate the crank shaft by using a box wrench on the acorn type nut holding the pulley down. Stick your finger over the plug hole. You are feeling for the compression stroke, that is when the piston reaches TDC and declines to BDC without either valve opening. So when you feel air pushing from the combustion chamber (cylinder), that is when the piston is compressing the air/gas mixture. If the the crank is rotated a few more degrees (15 or somthing) the flow will change and the piston will try to suck you finger into the chamber. When moving beyond the compression stroke you are simulating the power, downward force, provided by the mixture being ignited by the spark plug. Find the spot between the two strokes and that is TDC. Now look at the flywheel or flex plate and line up the marker with the degrees BTDC indecated by your manual or 10-20 B. If you choose not to pull the spark plug you will be able to continue but might have to give a second try. The cam shaft will rotate once for every rotation of the crankshaft. That means if the 0 deg mark is showing the the compression or exhause stroke has completed. What is comes down to is may needed to reset the disty because you were 180 degrees off on the disty gear. 2. Set the distributor. Most manuals will describe a system using two arrows... it's confusing. They instruct you to find TDC and then aline the arrow on the exposed case with the dot on the shaft. If you want the sure fire way, well here you go. With the disty dis-engauged from the drive gear on the cam shaft, remove the disty cap. Rotate the shaft by turning the ignition rotor (the plastic cap with a strip of metal on the top). Since the engine is at the point which it requires a spark at the first cylinder, the rotor should point over the the first cylinder's spark plug wire on the disty cap. At this point you might see where the arrow system works. Set the disty into the cam, locking the gears. Check the cap one more time to make sure that the rotor is where it should be. This might take a few tries. 3. Fire her up! Replace the spark plug, cap, wire, and vac advance lines, if any. Make sure everything is ready and then fire her up, if she will.

Don't pull out the disty from the cam until you have run out off of space but keep in mind that most likely if you did step 1 & 2 correctly it's all good but might need a second person so you a examine the timing light while someone rotates the crank using the starter. Locate in you manual the degrees recomended for your model. If you have an auto you might want to consider asking others for the best degrees for the best results.

MudisFun Posted March 9, 2005 Author Share Posted March 9, 2005 See, there's graps and more to add. I figured maybe some one would have something good to add... Link to comment Share on other sites More sharing options...
