vibrating

[tintoy]

I've change my timing belt and used a brand new belt (old stock), all timing marks are in the correct place. every time I rev it @ 5k rpm the engine vibrates. does the vibration is cause by the old stock timing belt? /ubbthreads/images/graemlins/confused.gif

Your rear balance shaft is probably not in phase. You can have the rear balance shaft 180 degrees off while the timing mark still lines up.

OR

Your belt is not tight enough. Sounds like you need to get back in there either way and double check everything. Normally when someone does not have their rear balance shaft in phase, they get vibration much earlier. Other instance of vibration, heard more than felt, was when my buddy's timing belt was not tight enough.

does it also cause hard starting? when I start the engine the rpm wont raise, when I hit the accelerator the engine chocks then it rev's up. /ubbthreads/images/graemlins/idea.gif

 

[tintoy]

question; can a mis balance pressure plate (clutch) can cause the vibration?

 

[Barnes]

If the only thing you did was to change your timing belt and this happen, you did your timing belt job incorrectly.

i'l check on belt. thanks /ubbthreads/images/graemlins/smile.gif

Did you remove the balance shaft belt? I would recommend removing one time while you are down there.

 

[Barnes]

Hold up. Unless he removes the rear balance shaft, he CANNOT remove the balance shaft belt.

However it is worth asking if you replaced that belt? Is it still there?

 

[alansupra94]

I guess I should have specified doing the complete balance shaft removal properly.

my front balance shaft locked up..i removed the belt and did not do the balance shaft eliminator..i havent had a problem yet..now i am going to do it..just havent had the time

 

[cspetros]

^^You must have experienced wickedly bad vibrations due to the lack of the front shaft and the rear shaft still operating... There's no way around it.

 

[tintoy]

would it work if i just remove the small belt and not do the whole balance shaft removal? would it hurt my engine for just removing the small belt?

 

[91vr4394]

honestly i havent had any vibrations

Quoting tintoy:

Do not do this. Either remove the rear balance shaft and the front belt, or leave the front belt in. Do not remove the small belt driving the front balance shaft without removing the rear balance shaft. I don't care if someone else "hasn't had a problem", don't do it.

 

[91vr4394]

will this cause me any problems

 

[Barnes]

Potentially, but I don't really know for sure. Keep driving and let us know how it turns out. /ubbthreads/images/graemlins/smile.gif

 

[91vr4394]

I have to for now because its my only car and I don't have time to do it right now..But it runs great.

 

[tintoy]

i guess the 1 reason that i have to eliminate the shaft is the every time i replace my timing belt the small belt is broken or to lessen stress to the engine? or it keeps on breaking cause is not properly install? /ubbthreads/images/graemlins/confused.gif

 

[Barnes]

If the small belt is breaking, something is wrong. It should last atleast 50,000 miles without a problem. In addition to buying a new small belt, you need to buy a new pulley to replace the one the small belt goes over.

This all assumes you do not have the time or money to do a proper balance shaft elimination.

A friend of mine that use to be a mechanic at SBR told me it is fine..He has his talon like that and it's been like that for 3years now..He also said he does it to all his cars unless he has the motor out..
