need help putting my 1997 honda accord in time.I got the cam pullie on top and crank top dead center.does the oil pump gear haft to go straght up too.and one more thing when we get the belt on it keeps tring to roll offneed help bad.Can anybody help please?
after you remove the timing belt cover you will find a notch on the cam gear that lines up with a dot on the backing plate and also on the crank after the pully is removed the keyway will be at 12'oclock after the engine is set in time use a 8mm wrench and turn counterclock wise use a 1/8 drill bit to lock the tensioner in place now remove old belt and replace
if the belt is still on the dot on the camshaft should line up onthe 12 oclock if you look close there is a mark behind it the crank mark is about 10 or 11 oclock you will see the marks make sure no1 is at top dead center if all this is good look to the left buy the camshaft and there is another pully on the left under the camshaft this is the adjust pully to take the slack out lossen it and push it till the slack come out ok and yes it is a interference motor hope this helps
yes you will have to remove the timing belt and crank pully. It is not as bad as it looks. You might as well, while you are in there, change the thermostat and new Timing belt and tensioner pully.
The trick I use, (and I have done hundreds of Timing belts) I use a good paint pen to mark the timing belt and gears. make sure to mark it so you know what marks are for what cam and crank. and which direction it goes. then on the new belt crefully transfer the marks. then it goes really smooth and there is no guessing hoping it is properly lined up on the factory marks. and you dont have to line every thing up before you take off the belt either. just mark it and remove it where the motor stopped..If you do it this way, you dont have to worry about trying to line up the cams and crank to there respective marks, just the ones you made, then there is no mistake.
The crankshaft should have the timing mark on the crank pulley (Notch in the outer edge of the pulley near the keyway) It should align with the timing mark on the oil pump. (With the keway turned to about the 3 O'clock position.)
Align the marks on the camshaft timing pulleys with the corresponding dots on the front plate.
If you are installing a new belt, it should have 2 solid white lines printed on it that you would align with the timing marks on the cams and a dotted white line to align with the timing mark on the crank.
It makes a difference which way you put the belt on. (Which edge faces the front of the engine.) Most, but not all brands of belts have arrows and the word "FRONT" on them to tell you which edge of the belt shoud face the front of the motor. If there is no mark to tell you which edge is front, the letters on the belt must be able to be read correctly as viewed from the front of the vehicle.
There is a DOHC or SOHC (double or Single overhead cam engone. Both are Similar. Both have a notch on back side of crank pully that aligns with a tab on engine just above crank pully looks like a triangle with the tip near crank pully is rounded off. SOHC engines have an arrow on cam pully that aligns with a point at top of timing belt rear housing. about straight up at top of it. DOHC have an I and an E on the cam pullys I for INTAKE and E for EXHAUST. the I and E match up at same type points on top of rear Timing belt housing. When installing belt make sure you do not move pullys. put belt on starting with cam shaft (s) then down to crank on tension side which looking at motor will be the right side or Clockwise direction keeping it tight no, or EXTREEMLY little slack. then back up around tensioner. Tensioner should be the last pully to go around. Once on make sure timing marks still lline up.Adjust tensioner and. rotate engine BY HAND 4 times and re check marks.
Ibring piston to compression stroke. Apiece of tissue in the plug hole will blow out and then turn crank by hand until the piston is at the top. There should be timing mstks on the crankshaft pully.no timing marks? Then ease the crank around untill the piston starts to go done you can feel the piston with a straw. Note, the crank pully keyway more than like be at the 12 oclock position. good luck
