4G63 Balance Shaft Removal Q?

[SilverJester]

So my car died on me the other day and I was thining it was the crank angle sensor. I went to change it today and noticed one of the bolts that hold it had come off. Then I noticed why....my balance shaft belt snapped :eek: Well luckily it didn't get caught in the timing belt (hehe this is my second lucky break..no pun intended), but I don't want to risk it ever snapping again and getting caught in the T.B. So I want to eliminate it but was wondering if it was possible to pull the front shaft out while still in the car (2g)? If I'm going through all the trouble of eliminating the balance shafts I want to get rid of them both, instead of carrying around dead wieght.

i heard of that mod.dont do it.you WILL have problems.

[SilverJester]

No problems, I have had several friends do it (all while their motor was out of the car) and you can hardly tell the difference. I'm more worried about the problems I WILL have if my balance shaft belt breaks and gets caught in the timing belt. Not to mention mitsubishi offers it as an option when you go to get your timing belt changed.

theres mixed reviews on that.im pretty sure the cons outweigh the pros.its there for a reason.i dnt think the engineers would have that there for no reason,if it wasnt necessary they wouldnt have put it there and wouldve save tons on their production cost to manufacture that part.whatever floats your boat.if u put it in correctly you shouldnt have to worry about parts falling off. :)

Get rid of that crap. The balance shafts are worthless. They are only there to make the engine FEEL smoother. The 4G61T (basically the 1.6L version of the 4G63T) doesn't come with balance shafts at all. Most balance shaft removal kits out there are actually just 4G61T parts!

Your engine will last longer WITHOUT the balance shafts because:
A) less parasitic drag
B) zero chance of balance shaft/belt failure

That, plus more power = DO IT.

Sort of unrelated, but I removed the balance shafts in my Spec V (qr25de) over a year ago, and it's run like a champ ever since. A little more vibration, but that's it. Balance shafts SUCK.

x2. Mine have been out for 3 years and no problem. Slowboy has a nice kit for cheap. Good luck.

balance shaftless agreed.

talk about being outnumbered. lol

Empirical evidence does wonders bro.

There are many many parts that the engineers originally had on my car that are no longer there, for example....turbo/exhuast heat shields, that stupid hook to pull the engine out with, or how about the money they could have saved if the recirculation tube didn't stick so far into the intake pipe (free mod is cutting it off as it restricts 75% air flow). Not only that but Mitsubishi themselves, offer the removal of the balance shafts whenever you go to get a timing belt changed. No offense, but that is the worst excuse to not do something, if you are into modding car at all.

But my question is not wheather or not I should do it...I AM going to remove them. Just wondering if I can do it while the engine is still in the car? I know that technically I can leave the front balance shaft in, but that is just dead wieght, I wanna do it right and get rid of every unneeded part.

Oh and you can get the OEM parts to remove it from Satan for $60....and I got a friend that can get it for $30 w/ discount. So it's faster, cheaper, and easier to do it that way.

Sorry for the late reply, but you won't be able to pull the balance shafts with the engine in the car (well, there may be a way by dropping the motor mount and all, but it would be hard to do that way).

You really need to pull the oil pan and have room to slide the shafts out, etc.

It is best to pull the engine (seems it would be impossible or near impossible with the engine in). It is too much labor to worry about trying it with the engine in. You have to remove all the timing components, the front cover (from the block), the oil pan, the oil pick-up, the oil pump housing, remove the balance shaft bearings and re-install new ones, etc.


If you need this job done, I can do it for you. LMK

Ok so far I have gotten the both shafts out of the car; I did it with the motor still in car. I had to cut the front shaft with a saw as I could only pull it out half way (not the difficult). Basically I have have finally gotten all the parts I need to put everything together again but I ran into a problem when I was attempting the insert the new bearings and the rear one started coming apart on me while I was installing it. I wasn't too sure how I was suppose to install it and obviously I did something wrong....so my question is, how do you insert a bearing?

[SleepingTalon]

Heh, well, if you loosen the motor mounts, it makes it much easier. You've gotta let the timing side of the motor sag a bit so you can get to the front case. Anyway, if you're already at that point, you might as well just finish it the way it is. The one thing I'll tell you to be SURE OF, is to make SURE you get the right kit. There are a bunch of places selling the old version. You NEED the stubby shaft to have the groove in it so the oil can flow through it. If not, you can kiss your motor goodbye. I've put back together sooo many DSM's that have done this mod the wrong way. If you wanna be sure, just call Mitsu and get parts from them. Balance shaft eliminatin "kits" are Mitsu factory parts anyway. BTW, did you take the front bearing out, or are you trying to put the new bearing in w/o taking it out? You gotta take the front bearing out. It gives a nice increase in oil pressure by doing that.

Jeez, just when you think all the gimps are gone, one resurfaces! It's like the turd that you try to flush, but always floats back to the top! Hehe, what's up Pat? You get that car running yet?

Chillin man.... Car is running but still trying to track down that same bug. Need to replace a couple of couplers on the IC pipes and then retune it with the bottle....

[SilverJester]

Well I got the new ones in but thanks anyways. All that's left is the oil pan and timing belt. but to answer your questions, yes I did take the old bearings out first, and I did remove one of the motor mounts, just didn't feel like doing the work of removing the other 2 that most people usally do. I got all my parts from mitsubishi including the stuby shaft from the 1.8l motor.
And actually just dropping the motor a litttle by removing the one motor mount on thr driver side, was really not all that hard. Would've been easier if I had a sawzal instead of a hack saw but it worked. I used a nice long extension and axel either a 32mm or 33mm axel nut socket to push the bearings out.
