Took my car in to get Timing belt, balance shaft and headgasket replaced. I drive the car up the street and the entire car starts VIBRATING @ 4000 till 5Grand. IM like what the fck!?!

I take it back and the shop says they check the timing and its correct. They say its my clutch! I Call BS because there was nothing wrong with the clutch when I brought it in for the service so why all of a sudden the clutch is making the ENTIRE car shake at 4000rpms?

I called another buddy of mine and asked him what happens if the balance shafts are not aligned properly? His answer: Car will start to vibrate heavily at a certain RPM.

Does anybody have any experience with this at all?
When you time the balance shafts the timing belt has to be timed at the same time correct? Somebody give me some advice please thanks.

Yes your BS belt must be aligned when doing your TB belt. The front BS turns your oil pump which needs to be aligned with the tick mark and the pointer. The rear BS tick mark needs to be at about the 9 o'clock position, when at TDC. Take it back to them and make them do it.

 

Its already there... I refuse to drive the car and have something blow up because of their error. Anybody else want to chime in?

 

Then tell them to pull everything off so you can SEE the BS belt is aligned properly

 

oopI will. I looked in the Repair manual where it shows how to replace the TB. The instructions are in there how to properly align the belts. Question... after aligning the BS belts do you have to align them with the crank on the timing belt? Or it doesnt matter than timing & Balance shafts are all on one accord?

 

when you align the rear BS pulley, make sure the crank pulley is alligned before you slip the belt on. If the crank pulley is aligned the, the rear BS pulley won't be aligned when the turn the crank to line it up. the BS belt will be on before the TB goes on

 

Getting the front balancer shaft(driven by the timing belt, is also the drive for the oil pump) can be fun sometimes getting it to stay in line with everythign else...it will usually try and roll back one tooth on me at first.

However any competent shop would roll the motor over and double check it I would hope and/or think.

 

Thank you guys... Ill be looking at all the alignment myself tomorrow morning.

 

Remeber the front shaft that is attached to the oil pump can be lined up to the mark but the shaft is 180 out. This is why the bolt is supposed to be removed in the block and a screwdriver installed to ensure position. I can guarentee they did not do that since the turbo is in the way. Anyone who does them often can do it by feel without taking the bolt out.

 

TIM! Now that I didnt know at all. Thats new development! When you say 180 out you mean 180 degrees off?

 

How is that possible? The gear and the shaft are mechanically mated together. If the gear is lined up, there is no way it can be 180 out...it would be 360 out...lol.

 

Thats what Im kinda wondering. The shop owner said something about that also so somehow there must be one more piece of the puzzle that im missing.

 

The other piece missing might be the rear balance shaft being out of line. Did they take the original BS belt off.

 

This is the procedure that I have used several times in the past, it works every time...

 

but how can a physically connected gear/shaft combo with only one tick mark end up 180 degrees out...its impossible. If the oil pump gear is lined up with the mark on the block..its done.

Only thing is when you put the belt over everything, its extremely easy for the oil pump gear to move back one tooth, thereby upsetting your timing, obviously.
