Need help spun a bearing..

[whiteboyz]

Ok so today i spun a rod bearing. i dropd the oil pan and not only did i spin a rod bearing i found the bearing for the oil pump balance shaft all mutalated. my plan was just to replace the bearings but now i dont know what to do about it cuse of the balance shaft bearing. is it possible just to remove the balance shaft belt and call it a day and replace the rod bearings or is that a big no no? i have a balance shaft eliminater kit BUT i dont want to pull the motor out again if i dont have to. the crank and rod have very light scratches but nothing that emery cloth cant fix. any suggestions would be very great as im at a lost on what to do. i just put the car back on the road today.

well your going to have to pop the engine out... the crank will have to be checked and polishe..ground.. replaced as needed and the rod that spun will have to be resized or replaced as needed

alot of the guys here to not like having cranks ground, it may cut thu the nitrate harding of the crank

I doubt just rolling new bearing in will solve your issue....

If your balance shaft spun a bearing .. looks like time to do a BSE... and with that much failing I would check your oil pump too.

Listen to BogusSVO he knows his stuff.

Take the crank and get it checked. If they say it needs ground look in the classifieds for a used one. Like stated above turning the crank takes the hardening out and before long will spin another bearing. Also I would replace the oil pump because it is probly full of metal shavings. Spending the extra $ now will save you more in the future.

I have a spare oil pump and a good crank from my old motor. so should i just throw them in or just send the one out to get checked.

So if i use the counter balance shaft delete kit do i still use the balance shaft belt ? and i take it that i wouldnt have to worry about tryn to time with them as i did before correct or wrong ?

As long as your positive the oil pump and crank are good use them. If your not get the checked. go to vfaq.com and read up on the BSE install it will tell you what you wanna know.

ok thanks man, im going to check that out.

ok read the vfaq. a litlte confused. the kit i purchased did not have that little stub for the oil pump. is that needed or no ?

 

[ShawnsGarage]

Yes the stubby shaft is needed. There are people on here that have cut the original shaft but i wouldnt recommend it. If you wanna try it search for Free Balance shaft removal. Where did u purchase the kit?

Cut shaft is pretty much the same thing as a stubby shaft.

My friend bought the kit from extreme psi. here is another question if you are removing the balance shafts why do they give you new bearings for them? are they necesery to have them installed even with them removed ?

Even though the shafts are gone, the bearings have to be installed to block the oil galleys where the front and rear shafts use to be.

STM has most of the parts you'll need for this. The spare crank you have will need to be micro polished and checked so you know the exact size of the bearings to replace it with. You DO NOT need to pull the motor to do the BSE but it's easier to do with it out of the car.

I would have the whole block inspected and washed. Checking the oil galleys for clogs. Something major happened and you'll want to inspect it throughly.

I actually did not spin a bearing. it was still locked in place, just had play wich i think was due to the balance shaft bearing spinning out and made me lose oil pressure to the other bearings. as i stated in my first post there is just very very light marks on the crank. i called my local machine shop he said since the bearing did not spin i could get away with just sanding the crank with emeryclotch or 1000 grit paper not taking alot off. and using brake cleaner to clean it up. but i really eat that balance shaft bearing apart.

I was thinking the same thing about not removing the motor to do the BSE. was just going to drop it down on the driver side and let it rest on a jack and do it from there. but all in all im still abit worried and confused about the whole BSE. i read the vfaq. ust worried that when the BS bearing spun it eat up alot and i will not be able to put the new bearing in to raise my oil pressure back up.

sorry for the long post.

If the crank has scratches even if they are small, have the machine shop do it so it stays round and for piece of mind.

Did the balance shaft eat into the block or not? If it really came down to it, you could more than likely just weld the hole shut as you are not using them anymore. The bearings just block off the passages.

Yeah i am going to just give them my crank and have them do it just incase. not sure if it ate into the block. i will be pulling it apart tomorrow to see. i am not going to pull the motor out, just going to drop it down and see if i can get the pump assembly out like that.

Disassemble and clean everything! any metal shavings will kill the engine quick.

best of luck on the rebuild!
