Balance Shaft bearing Question

[icedearth15]

I pulled both balance shafts out of my car. I took both bearings out from the front balance shaft. My problem is I cant get the far bearing back in. I have a socket that fits in the bearing perfectly then steps up to stop the bearing. I keep seperating the bearing though. The reason is because the step up on the bearing isnt to radical so the bearing will ride up and push itsself apart over the larget part of the socket. I want to know if anyone can give me any tips to ge the far bearing back in. If I cant get it back in how much of an oil pressure drop will I get from just leaving it out and blocking off the front oil passage?

Here's a picture of my socket and setup I am using to pound the bearings out:

Thank You,
Dave

The pics seem a little dark to me, so I lightened them in case they're dark for everyone else as well.

Use the balance shaft to hit it in. I dont remember if its the front or rear, but one of the ends fits through the first hole in the block and not the second.

How did you hold the bearing while you pounded it into place. I cant get my hand up in the block far enough.

The small one is in the back of the block, so I put that one in first. Some people have had good luck with tapping that bearing in the the balance shaft itself. They are a PITA to get in, but for mine I couldn't find a socket big enough, so I used a rubber mallet, the head off of a smaller rubber mallet, and a socket extension. DON"T HIT IT WITH ANYTHING METAL! I ordered my block-off kit from SBR and they accidentally sent me 2 small bearings. They must have known I woulda messed up the first one. The rubber mallet way worked best, just take your time with it.

I wasnt able to get my in either. I just left the back hole open and closed the front one. Oil pressure with be down a bit but shouldnt hurt anything. Some people dont block either of them.

I'd close both of them, thats one of the advantages to eliminating them...added oil pressure.

The people that don't block either of them leave the front shaft in there with no belt connected and eliminate the rear shaft.

Thanks alot guys for all of the tips and input. I will try those things mentioned, I am not giving up yet.

Thanks again,

Dave

this question is for MXPIMP18 have u done it? wut did u get? is ## oil pressure too low

I used a piece of solid steel rod that was laying around the shop...Tapped it in some. Used the balance shaft a lil too... Just stick it on the large side of the BS, push it in, wiggle, make sure its in there....And start tapping in. If it doesnt seem to be in, re-try. Other wise knock the shit outa it...Doesnt matter if your not putting the shafts back in. Just needs to block the hole.

Turn the socket around 180* and use the flat-faced back side to drive it in.

I usually hold the socket in the ball park area, and come thru the front hole with a long extension, and just engage the socket from the front. Using the flat face will make the job much easier, and using a slightly oversize socket will ensure you don't drive it in too far.

A few taps on the extension from a plastic faced dead blow hammer, and it's a done deal.

I would strongly recommend against running without anything blocking the holes. It's not about oil pressure at higher rpm's, it's about oil volume at a hot, slow idle. Given a path of no resistance, I think you're going to bleed away too much of the oil volume, leaving insufficient flow for the rest of the motor....

(With the shaft installed, the oil has to flow thru the (very small) clearance between the shaft and the bearing, creating resistance. No shaft=no resistance)

Again, I would expect this to show up at a slow, hot idle.

If you run a turbo timer, do you really want to have a reduced oil flow thru the system for an extended period of time?
