new balance shaft bearing but its hard to turn??

[diamondsm]

i have a 95 tsi in the process of rebuilding the engine... the block was fully serviced and came with new balance shaft bearings, well anyways i just put my front casing on and slid the balance shaft in and after getting it all snugged down i went to turn the balance shaft and could not turn it by hand??

so anyone know whats up with it? could the bearings just be a little to snug? if so can i run it like this??

 

[crash89]

Did you put any kind of assembly lube on the balance shaft journals? And I wouldnt run like that.. You might as well just delete the balance shafts since theyre out anyways..

 

[2slow4now]

Don't run it. Just do a balance shaft elimination. They really aren't needed because they don't balance squat. The only purpose they serve is to make the engine vibration more tolerable for the passengers.

Don't run it. You need to find out what's locking it up and keeping it from spinning. Did it spin freely before you bolted the front cover onto the block? Try spinning it as you're torquing the front cover down and if you feel that resistance starts to build, you can narrow down your search and find the problem.

yeah i lubed everything up....i'm building this one for a buddy and he is not a car guy and i have already tried to explain to him that eliminating them would be the best idea but he wants to keep them so kinda need to fix it he thinks that if it came like that from the factory then thats how it should be ....i took the front casing off again and tried to use my front casing and balance shaft but still had the same problem i might just eliminate them and not tell him

That is what i would and just don't tell him. Or tell him that if you install them that the engine could fail because of it.

Yeah i agree. A buddy of mine blew a hole in his block because his balance shaft went. So you wouldn't be lying. They are just extra weight anyway.

 

[pauleyman]

Put another bearing in it. My guess is that one was damaged during install.

 

[born2tune]

Maybe when the bearings where installed they mushroomed out to create some kind of binding.
I wouldn't lie to him about not installing it, because if something happens later he can actually sue you if he finds out.
best options are that he either accepts the install w/o balance shafts and you finish it or if he still wants them on he can take his stuff elsewhere and figure out why they are not spinning fairly easy.
or if he wants to risk it, install the binding shafts anyways with the disclaimer that you are not responsible for squat after that. never hurts to play it safe.

Maybe you should let him know about this thread. Possibly let him know the dangers of leaving them in.
Breaking a balance shaft belt and throwing it into the timing belt ruining valves, guides, and pistons costing him bunches of cash.
Mitsubishi carries a stock stub shaft that was installed in similar cars that eliminate the balance shafts. Another words it was stock and made that way in some cars. They do make an OEM kit to do it.
Considering the tight condition of the balance shaft it would be better to leave it out than run it. I have seen several that have spun the balance shaft bearing but other than that the engine was mechanically sound.

Or tell him the plus side.
It's an OEM option. Higher oil pressure to feed the crank bearings. Usually no bad vibrations even noticed from doing it. A tad more hp to the wheels. It could help with gas mileage because of weight loss and the engine doesn't have to work to turn the weight. Less stuff that can fail.

Just tell him both and there are guys on here like Bryanwheat in this thread and others with very good reps from the site that have done it or recommend it.
Do the salesman technique tell all the bad then how great the other way is.

Tell him leaving it in will send the motor to an early grave, make him sign a waiver because when it does blow up it's not on you.

alright so i showed him this thread and thank you guys it made his decision we are eliminating the shafts but we are going home made because he doesn't want to wait for the eliminate kit to get here or spend more money..

when doing a home kit i basically just get a freeze plug cut the oil balance shaft and weld the hole in the end of it??

do i have to turn the bearings to block of the oil holes or can i leave them?? (need the most reliable option)

how much do i cut off the oil balance shaft?? i keep seeing post were it says right at the line and others that say a 1/4 inch past the line??

Yes you need to turn the front bearings to block off the oil holes. As for cutting the rear shaft, you want to leave around half an inch past the bearing surface. I prefer to tap the hole in it with a 11mm tap and thread a 11mm bolt into the hole with loctite than cut the bolt off flat with the end. From there you can take a punch and hit around the outside diameter of the bolt where it is flush with the shaft. This will lock the bolt in place to it can never come out.

sorry i dont get were your talking about? the bearing surface being the back of the oil pump??

 

[2slow4now]

He means the bearing surface at the oil pump. What you will end up with is a stub shaft. Look at the link I posted for JNZ tuning. They have a pic of what it looks like.

will this work?? if not i have spares

Yes it will work, that is why we recommended it.

i know that i mean its non to short?? or long??

Just look at this picture of a oem stubby shaft leave about the same amount yours.

so i'm having issues with getting the bearing back in on the second bearing of the balance shaft i'm assuming that i messed it up when removing it, if i only turn the bearing closest to the front casing and not the back one will that mess with my oil pressure allot? because the bearing i was trying to get in is toast and hes gonna be pissed if he has to go get another one i we were supposed to be dropping the damn thing in today just need to know if it will be fine??

No, you have to turn both bearings for the front balance shaft. The single one for the rear balance shaft doesn't have to be turned.

i figured thats what you were gonna say guess i got to keep trying
