Balance Shaft Removal

[91TalonTSi_53]

What all needs to be done to do this. Would it be ok to just order the kit and do it that way? Or does other stuff have to be done internally.

There is a VFAQ on this. The kits include everything, but it's a little bit of a bitc h to do with the motor still in the car. And knocking out and turning the bearings is also a little difficult. But it can be done.

i believe roadraceengineering.com sells a kit for the removal, instructions can also be found there....

Do NOT use any of the vendor kits for doing this. The stub shaft they give you has no oiling groove and they always leak eventually. Order the stub shaft for a 1.6l mirage from mitsubishi.

If you're doing it with the engine in the car just leave the front shaft in there and the belt off. It's too much work to take it out with everything in the car.

You don't really even need the kit. You can just cut and tap your original balance shaft, and use a freeze out plug to cover the whole for the other. There is a VFAQ on this too (but they might have gotten rid if that one).

3 keys to doing it.

1) Use a mitsu 1.6l stub shaft for the oil pump/rear balance shaft replacement. You need the groove.
2) Keep the front balance in the block to block the bearing oiling hole.
3) Keep the Balance Belt B (front balance shaft) tensioner in place and torqued to spec. If you get rid of it, use a shorter bolt with some RTV on it. If you don't, you will have a HUGE oil leak.

The mitsu plug fits better than a normal 1 3/8" (think that's what it is off of memory from a year ago) freeze plug. I used to do them like that, but now I prefer to use the mitsu plug instead.

Blahh... the Mitsu plug is a POS. I used the freeze out plugs for years. Then I listened to all the internet guys saying the mitsu plug is better. The damn thing kept falling out causing much aggravation. In the future I will stick with the freeze out plugs.

Anyway if you do use the mitsu plug make sure you glob it up good inside and out with silicone.

I use a 40mm (I think) freeze out plug. I coat the front cover and the inside of the plug with JB Weld, and the tap the plug OVER the hole. It fits very, very tight, and will NOT come out.
