Balance shaft delete

[97eagletalontsi]

Hello, I am new too the dsm world. I have a very strong vibration from 4K-5200ish. I’m not sure if it’s the exhaust I have which I was told it could be, also was told it could be the balance shafts.

I read some articles about doing them while in the car and everything. If I were to do them are they hard to do, what’s all needed, any special tools to retime it. I’m used to Subarus I can time a Subaru in 5 mins.

Was told these are a lot harder.

Anything helps! Thank you in advance!!

It’s not hard and you can get a delete kit from stm I’m sure there’s a video on YouTube but if u need any additional information I can walk you through the steps

I would advise you take the covers off first. I've seen balance shaft belt break then you only have one shaft moving. Also has it always done this? Could also mean they weren't phased correctly when the last belt was done.

Also asking for pms doesn't help the rest of the group. Keep it on the board unless there is a reason not to.
What is your mechanical skill level and then we can tell you our opinion on how difficult this will be for you. A balance shaft delete, if yiu need it, requires removal of all timing components, the oil pan and oil pump(front case).

Yes it’s always done it since I bought the car

I have a 1000whp sti I built myself. I’m mechanically inclined but Dsms different things and sounds could be different sounds and such in a subaru

You will have to retime and in my opinion I would think it would be better with engine out doing the process that’s just in my opinion

i had talk to him otp I was just telling him that highly agree

You're sound more than qualified. I don't think you need a delete. Somebody likely screwed up the balance shaft phasing. It's a well documented mistake.

Can it be done in the car or outside of the car?

Which one? Retimng is no problem. If you did choose to do a balance shaft delete, yes it can be done with the motor in the car but on my opinionn its a big pain.

Which tools are needed so I can order them tonight to make the job easier

 

[pauleyman]

Which job?

Not sure how its possible with the motor in the car. Unless you put it at a crazy angle. And at that point its easier to just pull it.
Best bet is to prepare to pull the engine if you want to do a proper balance shaft delete on it.

Your other option as already said is to keep the balance shaft and fix the phasing. For this you do not need to pull the engine. This is basically the same as a timing belt job. So i would suggest checking the timing belt and changing that too while you have it all open.

It's definitely able to be done in the car. Once the pump clears the snout of the crank you have to let the oil filer housing end of the cover drop down to clear the frame.

Another way is to slide the cover out enough to get the bolts off that hold gear housing and then remove the cover and balance shaft separately. In that case the motor doesn't have to be dropped much at all. That method is much easier on an automotive lift. Also easier done on 6 bolts than 7 bolts since the 7 has the one P3 screw instead of a real bolt

Yea I was thinking too it would be a pain not really able to see the bearings placement well

Guys doing the in-car delete usually just leave the front shaft in the car. That way you don't have to rotate the bearings to block the oil holes.

I think story would be different between 1g and 2g.
I have done that in my 1g long time ago but I remember that was a PITA. I have never done that in a 2g, but I wouldn't do that again especially if it's a 2G due to limited space. I am not so sure if I can do that in car if 2g. In a 2g, even there is not sufficient space to remove the water pump pulley, you would need to angle the engine to remove it and the water pump flange would interfere with body when angle a little bit.
Everyone has their own preference but if this is my case, I wouldn't even try if it's 2g, I would probably remove the hood and pull up the engine with a cherry picker to work comfortably from the beginning. I think that would be less struggling and trouble than doing it in car. Just my opinion.

I agree. I've done it in a car in a 1g but I wouldn't do it again in either car. I'd pull the motor.
Sounds like the op just needs to retime. Easy.
