A new idea for balance shaft?

[Nobleracer307]

Hey guys,

This is my first engine rebuild and I have a 1990 turbo charged engine. I ordered my topline rebuild kit from machv but the balanceshaft bearings i have do not fit in the block. They are to small and slide in and out of their bores. I think i am going to have to go with a removal kit but i have absoloutley no money . Literally... i might have like 8 dollars in my bank right now. But i did some research and apparently you can block off the oil going to the balance shaft bearings by replacing a bolt by a longer one? The oil lines going to the bs bearings is covered by this mythical bolt. I havent really looked yet but does anyone know where this bolt is? Or has anyone tried this technique?

Also can i just grind my balanceshaft off to make the nub? I don't see why not but no one has seemed to do this.

Thanks
Jordan

Just take the old bearing's out and turn them to wear the oil hole's dont line up and knock them back in. Thats what i did and i have had no problem.

 

[Nobleracer307]

Ya the problem is the bearings dont fit in where they are supposed to. They slide around. Im guessing the bore somehow got expanded when the engine got cleaned becaue the bearings are the right ones. I know this because they fit onto the balance shafts fine. I need to somehow block the holes without bearings. l have heard jb weld can do the job too but i would like some opinions on that.

 

[Nobleracer307]

I think i would rather not go with the jb weld. Im looking for opinions.

 

[ilco187]

if you know someone who can weld they can weld the holes closed.

 

[Nobleracer307]

I guess i could probably find someone to do that but that seems like a pretty difficult task. Theres not alot of room in there. Anyone else?

jb weld is a wonderful invention ya know.

 

[Nobleracer307]

Ill have to agree with that. But has anyone actually used jbweld for this? I really would rather just do the whole bolt idea but i dont want to go effing around with my engine. has anybody done this? My question I guess is what is the safest most economical way to seal the oil holes for the bs bearings without turning the bearings 180 (because this wont work)

Dowhat 90 talon awd said dont mess with jb weld unlessyou want to tear backinto it soon that stuffs good nut not that good

I wouldn't use JB weld to hold a thing on. Especially not in side the engine with all the oil and heat.

What happened to your STOCK balance shaft bearings that you took out??? You just need to rotate the stock ones so they block the oil hole. That is the Cheapest fastest way to block those oil holes.

Im a super cheap ass so I took my rear balance shaft out and CUT IT down. Then I welded the oil gallery shut and ground it smooth. It was a 100% FREE Balance Shaft Elimination!

You MIGHT be using the wrong bearing in the wrong hole. I believe the bearing toward the FRONT of the engine (timing belt side) Is bigger than the INSIDE bearing. Do you have them MIXED UP??

 

[Colt4G63 also]

^ Took the words right out of my mouth.

I highly doubt the bores are screwed up, unless you spun a balance shaft bearing really bad. There are holes in there without bearings in them. IIRC the bearings go into the journals that are further into the block.

As Jeff said, you can cut down your oil pump shaft, but you will have to weld shut the hole in the middle.

To clarify I didn't support using JB weld in this situation.

DO NOT USE JB WELD for this trust me! Unless you want thishttp://www.dsmtuners.com/forums/cylinder-head-short-block/332794-what-do-you-think-could-have-done-lack-oil-big-end.html

 

[Nobleracer307]

So no JB weld haha. Ya when i first ran into this problem I double checked that I put the right bearings in the right place. I noticed that two were identical and one had a little larger diameter and was a bit more skinny. I figured out where the bearings went by placing them on the balance shaft. They fit fine on the shaft and spun nicley. But in the block they also spun. Its very obvious where they are supposed to go. I guess the bearings might not be think enough? I sent my block to a machine shop and had it hot tanked so the origional bearings are long gone. I think welding up the holes is what ill have to go with. I would much rather just use the bolt technique however because this seems like a cleaner easier and safer procedure. But no one has done it? Doesn't it make more sense?

On the front of the block there is a few machine screws that protrude into the block. On first look, one would think that these serve no purpose, but its actually where the factory drilled hole in the block to drill into the oiling chamber so it can oil the Bal. shaft. I forgot the thread pitch, but the screw can be backed out. If you get a small tap, and run it deep into the oiling hole then it makes threads in the block, this is the hole in whitch your trying to stop oil from comming from. You match up the thread, and run a new, longer bolt in the block, into the hole, thus stopping the flow of oil, w/ no need for a new bearing. Put some pipe dope on the block side of the screw and use some gasket sealer too. Wam, no need for a block off bearing and NO loss of oil pres.

It works.

This is where I got the idea but nothing other then this was said. Just any advice on this such as what to use for pipe dope? and where is this bolt?

 

[FMFGSX]

Any pictures of this?

 

[J-VilleDivision]

Never herd of that before??

Anyone else....

 

[95GSXCO]

Its just a little screw/bolt on the hump of the block it should be a phillips! I have heard about it working! I was bored one day and thought I would try and take the bolt out and yeah good luck that guy is in there. But heres a pic of the plug it will be right behide the turbo when mounted.

Here's a write up on a way to remove/install balance shafts. Not sure, but it might help. http://www.dsmtuners.com/forums/art...s-bearings-easy-way-w-pics.html#post151839308

 

[JStrateger]

You might have gotten the wrong size bearings or they might have sent you two of the smaller ones. The front balance shaft bearing is larger than the back bearing so check to see that the bearings don't fit in either.

Also try using your stock bearings if you didn't break them, I just did my BSE kit last night and everything went smooth. I replaced the stock bearings with clevite bearings so I still have my stocks if you want them. Measure the diameter of the bearing you have, my stock ones measure at about 4.4mm

 

[Nobleracer307]

my uncle took his caliper but ill check that out tomorow for sure. and i really appreciate the offer but canada is a little ways bud haha. I just put some wd-40 on the screw and ill try to get it out sometime tonight. the write up would have been perfect had everything worked out like it was supposed to. im going to give this a shot though and try to block it off with a longer bolt. can anyone tell me what pipe dope is though? and how far back do you think i should go?

 

[95GSXCO]

Pipe dope is just thread sealnt. Its teflon tape but in liquid form.http://www.permatex.com/products/Automotive/thread_compounds/a_thread_sealants/auto_Permatex_High_Performance_Thread_Sealant.htm

 

[Nobleracer307]

thanks 95GSXCO. i took a look at the setup and i guess your essentially taping the bearing hole itself.you just use the hole the screw-bolt is sitting in to reach the bearing hole seeing as they are obviously alligned. Then just throw in at bolt that will stretch accross the diameter of where the bearing would sit. Im hoping my tap is long enough to reach it. if not i guess ill get it welded shut. thanks for all the help guys

 

[Evilimports]

Could't you use a freeze plug with the correct diameter?
