well i got into the front of the engine to do some preventive maintenance replace the surpintene belt the water out let spout.. well i looked at the timing belt and it looked like it was ready to go... soo i took the power steering bracket off pulled the harmonic balancer took old one off i set the crank shaft on tdc with the deg. gauge on the pully cover. aligned the triangle with the other one on the cam and then the oil pump drive i aligned that also prolly not critical beings its not a distributor engine.. well i rolled it over by hand just to make sure no valves would hit or anyhitng started it up run great.. well get going down the road 1st gear up to 15 hit 2nd gear kinda let it lug its self along and she jerks bad... not like a regular to high a gear and going to slow jerk it really goes back and forth bad.. shift down and run the gear higher and theirs no problem dosent do it.... and it did not do this b4.. b4 youy could ride 4th gear doing 25-30.. just kinda chug along... so did i do something wrong could the timing be off i noticed their a a spot on the crank sensor that has a tooth missing off from it (not broke) and that is supost to be a 36o mark...? well i seen that on a 4.0 diagram is this something i missed....so i guess im looking for a from start to end what is the exact steps... not just mark the belt and hopefully put it back on but the line this triangle up with this one and the crank up with the cover.. i just dont know.. if someone could help me that would be great thanks
 
you align the cam triangle to the triangle on the rear timing cover. and the oil pump sprocket you line up the diamond with the diamond. it is important because the oil pump drives the cam sensor assembly

im not exactly sure which has the diamond or the triangle, but you just look at the mark on the plastic and match the shape on the sprocket. check to see if that is right
 
well the actual mark is not on the sprocket its self its a keeper to keep the belt from walking off the sprocket.. but they both have triangles on them... and when i put the crank on tdc with the line that is on the harmonic balancer and ck the 2 soft plugs and look at the triangles.. they are perfect in line pointing at each other.. but.. do you have to i guess time it by puting the harmonic balancer at like 10 o... im just not sure just changing the belt should not make this jerking the way it is..

no, you REMOVE the balancer and line up the small dot in the crank sprocket to the timing mark, then like up the triangle and the diamond, i know there is triangles on both and diamonds on both, but the timing marks on the plastic are either a diamond or a triangle and needs to be matched respectively.

getting the cam sensor out of time could definetly cause bucking under load
 
ok i did see that dot on the the crank sprocket line that up with the theirs a lil V" notch near it.. ok ill give that a wack... ok so what the purpose of the timing grid on the cover...? anyways thanks for the info ill try that and see what happens
 
there isn't much purpose to the timing marks on the cover, half the time they aren't even lined up properly, the only reliable way is to line up that dot. did you find the diamond?
 
hmm. i rember seeing the diamond and the triangles on their tho.. im at a buddies house right now to get some help about this matter.. ill ck into it when i get home
