after he rotate it clockwise. he rotate the crank counter clockwise to aline the timing marks. but the crank marks was way off. only the cams was aline. so then he took off the belt without alining the marks on the crankshaft ,he then after aline the crank and cam to TDC without the belt installed .after that he put the new belt on .and tried to start it .it won't start. only cranks ,wont start . i'm sure the timing is off big time ! How can he reset his timing.( also if this helps while trying to start the car ,didnt hear fuel surrge ) weird. someone pls help !I have a friend who di a timing belt change on a honda and he rotate the crank clockwise. how can he reset it?
Whoa!! I don't like your friends style. He may well have bent some valves, if they weren't bent already. You didn't mention the engine name, but you can find out online whether it's an interference engine or not. Honda engines rotate Counter-Clockwise!! Turn the engine by hand (a socket on the crank bolt) until the TDC marks align on the crank. Loosen the tensioner and slip the belt off the cam. Rotate the cam until the mark lines up and if it's a distributor model, the rotor points to 1. Have the belt tight on the side opposite the tensioner and release it, turn the crank CCW (Counter) 45 degrees (!/4 turn) and tighten the tensioner. Turn the crank BY HAND 2 complete revolutions until the crank comes up to TDC. Look at the cam marks. If you can't get it to line up perfectly, always advance the cam, never retard it. In your case, the mark on the cam will be to the LEFT of the mark on the valve cover. Don't bother putting the cover or anything else back. Crank the engine and see if it runs well. Shut it right off. If not, check the compression. If it's low or no, you'll need to remove the head and see what's going on. Look at the pistons and valves (with the cam removed) and see if anything is bent or otherwise damaged. If you don't know what your doing. Don't do it.

I like your friend's style. He has no fear. My kind of mechanic. He is probably off by a few teeth.
Belts break all the time when the car is running - messing up the timing real good. There are proper procedures for each car how to set up the timing.
He should get a book from the library or search online for the procedure. AutoZone.com has online manuals (a little lacking on pictures). Go thru the procedure step by step carefully knowing that you can't be off by one tooth.
He'll get there eventually.I have a friend who di a timing belt change on a honda and he rotate the crank clockwise. how can he reset it?
If the belt is way off... your friend has now bent his valves.
Good luck, and hope he has it when buying a new motor.I have a friend who di a timing belt change on a honda and he rotate the crank clockwise. how can he reset it?
He should be able to get the mark lined back up ,then pop the distributor cap off,see where the rotor is pointing, then move the 1 spark plug wire around to where the rotor is pointing at on the distributor ,now put the remaining plug wires in firing order from the 1 plug wire. Your just moving the plug wire around on the distributor cap to match the new timing .I have a friend who di a timing belt change on a honda and he rotate the crank clockwise. how can he reset it?
He has to remove the accessory belts and the top timing belt cover, then loosen the bolt on the tensioner, push it back and re-tighten the bolt. Then he can set the timing belt and finish up as he did before, but without turning clockwise!
I think he may already have noticed the belt does not want to go on with the marks exactly in TDC position. That seems to be the standard with OHC engines, that the cam(s) hate(s) to sit at TDC. No matter. He has to be sure he pulls the engine through CCW a few revolutions to make sure the belt is right and staying right. Even new Honda tensioners don't seem manly enough to ensure the belt doesn't jump a tooth, and I have had to manually jam the tensioner against the belt and let it rebound before tightening to keep the belt from riding up on the cam sprocket. And of course the belt will jump if turned CW, as he already knows.
I wouldn't sweat the valves. The whole problem of interference occurs when the pistons are all the way up, so if the timing didn't go off more than about 30 degrees relative to the cam (60 degrees on the crank) it should be fine.I have a friend who di a timing belt change on a honda and he rotate the crank clockwise. how can he reset it?
Often when you put the timing belt on, the camshaft sprocket or crankshaft sprocket moves. So you need to take the belt back off and put it back on so that the lines mark up after the belt is fitted.The marks on the crankshaft pulley or sprocket must line up with the mark on the timing case for top dead centre and the camshaft sprocket timing marks must also align
