So Im changing my T-belt on my DOHC ZC (D16Z5) and every time I put the belt on there, its loose in between the cam gears. I am using the LOM Industries Cam-Lok kit to hold the cams in place. I am making sure everythin is lined up (crank, etc.) but I still have slack there. Is there something I could be doing wrong?

 

did u buy the right timing belt? I had an issue once with mine where they gave me the timing belt from a 2.1 prelude i think the 1 you needs from a 2.0 14400-pk2-004 is the part # also check youre tensioner the spring on it might be worn out hope this helps GL!

 

The tensioner will take up that slack once it starts spinning

Usually yes, but at times you will actually need to pull up on the tensioner a little then tighten the bolt.

Follow the helms book , I think you rotate it 3 teeth, if its still not tight enough, pull up on the tensioner. Usually it won't be tight on the front or back side, its usually feels tight enough around the cam gears

 

lol i just dealt with this **** last night, ******* cams kept slipping. keep at it and you will eventually get it. everytime i would have the cams set at TDC the crank would be off a tooth lol, then id go fix the crank and the cams would slip.

 

how are you trying to set the cam gears?

 

theres afew ways to set dohc zc engine timing the lazy way to do it is to losen the tensioner then set the crank onto tdc then u haveta get 2 socket wrench's or wrench's and manually hold the cam gears at the right possition while u have someone else tighten the tensioner atleast thats what happened with me or u can remove the valve cover and use punch's to hold the cams at the right possition.

 

I have a tool that hold the cam gears thats not the issue, the issue is when I put the belt on its way to loose between the cam gears. I cant get it to sit on them with no slack in the belt. Its like the belt does not line up with the teeth on one side the right way or something. Im sure I have the right belt, I ordered it here in Germany specifically for this engine.

1. Remove upper part of timing belt cover and remove the valve cover
2. Line up TDC mark (the mark off to the right of the 3 marks that are close together) on crankshaft pulley with mark on timing cover or if you have pulley and timing cover off, line up the mark on the crankshaft timing belt gear with the mark on the oil pump housing
3. Loosen tensioner bolt and take hold of the belt on the back side (toward the firewall) and pull up on it as far as you can to get slack in the belt
4. While holding it up, tighten the tensioner bolt
5. Do the exhaust cam first - with marks at crankshaft lined up, lift belt off the exhaust cam gear - put a 12mm box end wrench on the cam gear attaching bolt and rotate the cam until the mark on the right side is at 3 o'clock (up arrow up) - look down at the top of the head at the cams - on the back of the first camshaft bearing caps behind the timing gears you will see a little tab sticking out that has a hole in it - sight down through the hole and look at the cam - the cam has an alignment hole in it directly below the tab - when the cam is lined up correctly, the hole in the cam will be dead center below the hole in the tab (by the book, you can drop a 5mm straight pin punch down thru the hole in the cap into the hole in the cam to hold it in place - unfortunately, the holes in most of the cams are slightly bigger and sometimes tapered a little so that the punch doesn't necessarily hold them in the right spot, so this doesn't always work right) - with the cam lined up with the hole in the tab, hold the cam in position with the wrench - take all of the slack out of the front side of the belt (toward radiator) without moving the crank and place the belt down on the exhaust cam gear and hold the belt to the gear
6. Next, do the intake cam, lining it up the same way that you did the exhaust and remove any slack in the belt between the gears - hold the belt onto the gears and loosen the bolt for the tensioner - make sure that the tensioner moves all the way to the left
7. check to make sure that the crankshaft timing marks are still lined up correctly
8. With tensioner bolt loose, rotate the crankshaft counter clockwise (to the left) 1/4 turn or 90 degrees
9. Tighten tensioner bolt to 13 ft lb

 

Well said jlicrx.......I just didn't wanna type that much.....lol
