hi, i have a b18c5 and i was changing the timing belt and was having some issues. when ever i put the timing belt on it ends up moving just a little. first i lined up the crank with the tdc mark and then the cam gears with their marks then put the belt on. after i turn the motor three teeth, i tighten the tennstioner and rotate the motor six times, and it ends up being a little off everytime. any help would be very helpful, thanks.

Note how is moving, then reinstall the belt off the same amount of teeth and see if it ends up where it needs to be when you turn it 6 times

 

i did that and no mater where i put it it goses to the same spot. it is really werid. could it be the tensioner. that is the only thing that is different.

is the tensioner loose (free of any tension)? also, if you get someone to help you, it'll make things alot easier as far as sliding the belt back on.

 

Then loosen the tensioner, slide the belt off the cams, reposition the cams manually pushing them while the crank is at TDC, slide the belt on the cams, then tighten the tensioner and try again. This should fix it, it did for me a couple of times...

 

if you can't handle it on your own, get someone else to pull the tensioner while you get the belt over the gears.

 

alright thanks alot i will try. thanks

step by step.. and don't put on any pulley till i tell you too!!

put the belt on the crank first...

keep a lil tension on both sides of the belt with your hands(so it doesn't skip) and slide left hand (exhaust side) up belt to meet cam pulley

make sure cam pulley is where you want it (you may have to finesse it with a wrench on the 12mm at the end to get it perfectly lined up with belt teeth and the top of the head ,respectively)

don't let go of the belt with that right hand

place clothes pin over belt and exhaust cam pulley so it doesn't skip (makes it easier and one less headache)

don't let go of belt with that right hand.. its keeping the belt in the pulley teeth because if it skips you have to start all over again

feed left hand up belt from exhaust to intake cam

get them lined up on the intake cam pulley like the exhaust

another clothespin

don't let go with right hand and don't worry if the crank spins a lil.. we'll get the slack out the belt later. JUST MAKE SURE IT DOESN'T SKIP A TOOTH OR YOU START OVER

now with left hand feed the belt over the water pump

now feed it onto the tens (much easier if you make it open all the way up, loose)

now slowly let the tensioner take slack from between the water pump and itself, then from the crank to itself.. MAKE SURE CRANK SPINS WITH BELT IF IT NEEDS TO, JUST DON'T SKIP A TOOTH BITCH!! or you'll have to start all over

by now the tensioner should be doing its job... and the slack is gone from both sides of the belt. tighten the tens down now

you may have a lil at the top between cams.. which is normal, just a slight bend in the belt between cams, not a perfect straight line

now crank the engine from the pulley by hand a few times to double check

engine should be in time and belt should be perfectly tens (not TIGHT, but def not loose either)

go out an burn some rubber

 

that worked perfectly. thanks a lot i will keep that info for future projects. thanks man

 

not to thread jack, but if you had this problem and started the car up are there any problems? other then the TDC being off?
