balancer shaft removal

[xtremeleo]

imo, we have to find what causes the said failure rather then removing it. oem placed it there instead of doing a full balancing on the whole assembly, there must be a reason for it in terms of reliability and comfort.if it does fail, there must be for a reason, i strongly believe dat sir. what i can think of, the bearings fail for sum reason, and seeing dat dis failure only occurs in sum engines only, makes me think dat whether the owner is not one to be sensitive on noise. bearings make lotsa noise before it fails fyi, a loud humming, whining noise. anybody had dis failure ever come across dis or, it just failed all of a sudden jer? not likely to happen imo, but not impossible either.

lets all troubleshoot during dis festive season, shall we? lol

i must get a life laa, raya dah ni.. still online zth kaaa? selamat menyambut eidul fitri to all

Power the balance shaft belt loe... I've yet to a those kelvar belts snap :)

Spend so much on the other stuff. Tambah sikit for some peace of mind laaaa

i dont understand alucard, raya mood is in, i just understand kuih raya jer now, lol

i was just thinking, is there any marking on the balance shaft pulley? can it be dat the balance shaft was not aligned properly when it is installed in or when the timing belt is removed and is installed in? i can understand if the balance shaft is not aligned properly as it shud, the whole balance of the assembly wud be off, and dis wud affect the vibration dampening capability and wud amplify it at the resonance point (everything has its resonance point fyi, everything), and wud be very damaging if its run at dis point for a long duration. dat wud really explain the bearing failure, and y the belt may have snapped and causes damaging results.

to think dat the balance shaft is fitted in all 4g63, i dont dare think dat mitsu havent found a replacement for it in their billion dollar research on dis engine alone.. it must be there for a reason imo

Of course got laaa...

Of course got laaa...

alucard, u have full diagram of this?

 

[xtremeleo]

i cant thank you enough for providing us with the diagram alucard

so there may have been misalignment of the balance shaft then? i dont see many mechs give attention to these additional markings when installing the timing belt, the one dat does, ive never heard any issue on the balance shaft causing any trouble from their work. interesting..

Agreed & Thanks Alucard...

Hey... no probs guys. Glad to be helpful. I have that from the engine manual for the 4G63. But it got hijacked by my mech now. I'm sure you could get this from the googling :)

 

[xtremeleo]

mood raya sir, not into doing any research rite about now. dis is a new issue for me, prior to dis i only knew people remove the said shaft to increase power jer..

some updates- vr4 block without balancer shaft installed and the result is superb!! very good response at low rev and very very minor vibration to notice...oil pressure all fine, as normal...still running in mode...anyone can reccon what mileage to run in?

 

[xtremeleo]

just be careful of dat vibration, resonance can even kill big bridges sir..

if want running in the engine,better is 5000km for safety

if want running in the engine,better is 5000km for safety

so while running in can we low boost? like 4-5k rpms?

did u just potong the balancer shaft or did u use a eliminator kit??
coz i heard if you do it the proper way there will be almost negatives plus u reap all the benefits
but this method is definitely more costly than just simply potong

kumar, i send the oem balancer shaft to machine shop and machine it to the spec of the eliminator kit...so u can call it home made eliminator kit
