Crank Removal

what up guys, need some quick answers, i removed the crank pulley bolt, and the main bearing caps from my b16, but how do i get the crank out? there is no notch or anything for it to just slide up like on the other motors ive worked on? so how do i get this thing out?

no one ever removed there crank from the b16?

c'mon guys i need to get my block honed for the new piston rings, and the shop wont do it for me.

Remove the bearing caps and pull?

:confused:


Its just like any other piston engine as far as I know.
I assume the engine is upside down?
In which case the only things that hold the crank in place are the bearing caps. Remove those and it will come right out, assumeing you have also removed big end bearing caps as well.
If the rods and pistons are still attached then its going to be a real bitch, as you have to work against the piston rings as well. Simple rule, pistons out the top, crank out the bottom ;)


or prehaps you need to do a few reps at the gym? I know cranks can be heavy, but it shouldnt be that heavy :p :p :p :p :p :p

you have to remove the oil pump and rear mainseal

ok i removed all that shit, but from looking at the block, it seems there is no notch way to pull the crank out from, like the block was poured around the crank? it makes no sense to me.

LOL!

Are you sure you have removed all the bearing caps? and the main seals?


and have you got access to a Digi cam so you can show us some pics?

yea take some pics maybe you can send them to ripplys belive it or not(the tv show)

LOL! :D

i swear i got all the bearing caps off and the crank pulley, i'll try and get some pics of it tomorrow with my moms camera, but like i said its like the block was poured around the crank, unless im just totally missing something.

you sure you didnt take off the oil pump????

i swear, all im looking at is the crank with the block around it, on one end is a gear where the timing belt goes, and the other side is a metal disk that hold my torque convertor, neither one seems to be removable.

Dude...you have to remove the girdle.... when you turn the motor upside down, it is the part the supports the bottom of the crank when it is in the car.

Check out The Old One's site. http://theoldone.com/articles/badtothebone/

this article is about building a b20 - but it has lots of pics that should help you out...and figure out how to get it apart. ;)

Dont you have to remove your oil pan also?

I would hope he's already done that...but maybe not..sometimes it is the obvious shit that gets overlooked :(

ok people im not that stupid, here are the pics i promised you all, this is from the oil pan looking into the motor. sorrry if these are huge, im not on my home PC to shrink em.

i have never removed a crank but what it looks like you should do is remove the TC and then just pull it out at an angle

Your a licensed mechanic and you can't figure out how to get the backing plate for the torque converter off? :lol2: :lol2:

Its a bit hard to tell from the pic, but they like either 12 or 14mm Multi hex bolts, or 14mm star drives. (ill put my money on them being 14mm multihex)

You will then need a bearing or gear puller to remove the cam belt gear off the front, and from looking at the pics it looks like the bit around the rear main seal, lifts out from on top of the crank.




And on a side note, you do realise the Automatic B16a's have considerbly less than 160hp to stop them eating the Auto G/boxs.

hey, your oil pump is still attached to your block you need to remove it, plus take off your torque converter as well, first take off oil pump, (its like 6 10/12 MM bolts..then take off that torque converter, then you will be able to lift the crankshaft off the oil pump side and be able to slide the end of crackshaft out the hole where the torque converter connects.

ok there is no torque convertor on the motor, i already removed it, anyway, the auto box b16 have 158hp so not real much of a difference there, anyway, i tried getting those hex nuts off the TC holder but obviously to no avail, im ordering up my air tools tomorrow so hopefully ill get this project back underway soon.

Are you sure on that?
Everything I have found places them at something closer to 140-150ps.

from what i keep reading it says that the auto b16 is always 158hp, and that the slushbox isnt as bad as most autos on the planet, but ill let ya know.

anyone else?

Dont tell me its still stuck in there? :frown:


or are you worried about not having the full 160hp?

no the 160 aint bothering me since im changing bout everypart on the motor for added power, but it is still stuck.

if i just drop the new pistons in without getting the block honed, what will happen?

The rings won't seal properly, it will be low on comression and it will use oil.

But you can hone the cylinders from the top, and dont need to remove the crank.



The crank should come out easily.
Useing a multi hex socket to remove the backing plate. You will have to hold the crank in place with something, and prehaps use a large breaker bar.

Then look at the fount of the motor, there are maybe 6-8 bolts holding the oil pump on the front of the motor. Undo these and take it off.
Use a gear puller if you have to remove the drive gear.

Then the crank will come straight out and you can get the block cleaned up properly and put some new bearings on the crank.

If you can't get it apart, or cant take it into work to get it apart then you need to consider revising your sig mate.

Yep, what evrybody else said. Oil pump and TC need to come off before the crank can come out.

i dont work at a shop, so taking it into rite aid wont do to much:tongue:

um, im getting my air impact wrench on fri, so hopefully i can bust off that backing plate without too much problem, and know i gotta get a gear puller too, oh well life sux in rebuilding motors, thanks for the help guys.

No worries mate, its what Im here for, and it sort of reminds me of the old days, when there werent all these damn kids around asking the same stupid questions every week.


Have fun with the Air Guns! :bigthumb: :bigthumb:

dude, you still have your oil pump and main seal holder thingy (thechnical term:cool: ) holding in the crank, take a closer look where there is some white goo on the block, scrape it with a razor blade you will notice that is seperate peice from the block itself.

you will need to remove the flex plate first (a little more difficult without pistons in the block however it can still be done. )

get a scrap metal plate and bolt it securly to the block, then bolt the other end to the flex plate, this will prevent it from turning with the crank, remove bolts, remove oil pump and other doohicky and the crank will be freed.

licensed auto mech?

i never said i was a good mechanic, just that i was liscensed.:tongue:

anyway, i never ran into all these problems doing the motors in my classes. can you guys like circle the shit i need to remove to get this out, i know bout the oil pump and the TC plate thingy. but visuals help me alot.
