Balance shaft bearing

[webconnect]

Hi guys, I was able to take out the front rear balance shaft bearing, and the front front bearing, however, I cannot put back in the rear bearing! I broke my stock one that I was trying to put in juts rotated, broke an after market bearing. I then ordered a new bearing and broke that one too!

So,
Can I just rotate the front front bearing, and install the stubby on the oil pump. Of course I deleted the front balance shaft and capped everything properly. How much oil pressure will I loose? (Because there is no front - rear balance shaft bearing)



Just for clarification, I am talking about the bearing in the block that gets oil from an oil squirter injector thing, not the shaft.

no you need that bearing u will almost have no oil pressure go to local part store and get cheapest ones they have buy 2 so if you break one you have another

Of course I can't find it, but I read a post earlier today that said you will have slightly lower oil pressure, but nothing bad at all. He had ~ 2k posts if that makes a diff.

o ok but thats like playing with fire littlerly i just woudnt take the chance if you have no oil youl f**k up everything and everything on these cars is not close to cheap

Agreed^^^ Do it right the 1st time, what happens if you have too low of an oil pressure? A lot of stuff will have come apart and it will be harder to do it later (both physically and mentally).

I have done it I broke one but what you need to do is turn the motor up side down and you will need a second person to hold the bearing in place when pounding it back in this was the only was to get it in with the crank on i havent tryed with it off yet but It took me about a week to figure it out and i got pissed and turned the engine up side down and it was cake very easy I even had my head on even tho thats not smart but i got it in since thats the one thats a pain the farest one in there.

Really? You should have been able to get the one back in that you took out. You need to use the front balance shaft to push the rear inner bearing out. I also used the front shaft to pound the rotated bearing back in.

Make sure you pound it in so it is even all the way around. You must be getting it crooked in the hole. Also put the bearing in the freezer overnight, and then slightly warm the balance shaft journal with a propane torch. Once it is nice and warm then try to put the frozen bearing in. But be careful not to get it Crooked. The bearing will be more brittle now that it's frozen.

Put a little oil or grease on the backside of the bearing before you try to pound it in.

Thanks guys. I have been trying everything listed here, but not the freezing the bearing. I will try that. What about buying this bearing at an auto parts store? Didn't think that was possible!

I just wanted to point out for those wondering about leaving the bearings out as in post #3. Leaving the old bearing in, with the oil holes lined up and nothing in the hole will lose a great deal of oil pressure. There are really only two options:

1. Replace or re-fit the bearings so that the oil holes are blocked

2. Leave the bearings in-place, but leave the front-shaft in the block. Oil will still flow from the oil holes in this case, but not substantially. As the VFAQ for this states, there will be slight oil pressure loss, and for an older engine, may not be worth it.

Leaving the front shaft out, however, and the bearing oil holes open is not a good idea.

In the case of the original poster, the bearings had already been removed so replacing them is a must no matter how you look at it. (replacing them so the oil holes don't line up would make the most sense in this case, of course)
