hey can any of you help me i need to know how to measure this crank to tell if its an ls crank. it is suposidly out of a b18b i just need to make sure. thanks

 

what do the stamps say

 

the thing is there is a bunch of stamps all accros the crank some say A2 other just A and just 2 there is also a P and two 4's stamped in it. anyone know??

 

i can go in my Garage and check but im hella lazy right now

 

Can't tell what crank that is, but #2 main journal looks pretty wasted

 

thatd be no.3, lol

huh? j/k?

 

rod journal width should tell you what you need to know

 

Thats journal number 2.

well then do you know what the rod journal width for an ls crank is?

 

it looks like its been out of the motor for a while and sitting.

ls = .935", same as b16/b17

gsr/typer = .858"

that's the con rod width, but it is enough to help you figure out journal width

so then how can i tell this isnt a b16 or b17 crank? are any of the bearings different between ls and b16 and gsr? if so couldnt i just get the ls bearings and see if they fit? and what do you mean by con?

 

Then you would check the stroke right?

 

just put it in a ls block with some ls rods and see what it is lol

yea but i need to get everything balanced before i assemble the motor and if it turns out to be the wrong crank i will be extremely pist off im sure you could imagine.

 

why dont you take it somewhere to get measured&gt;?

are the stamps youre talking about all separated? or is one like "pr4" or something....

 

Looking at the picture I say its a ls crank. The rod journals look wider then gsr.
You could also take a rod bearing and lay it on the journal. You should be able to tell from that.

because i live in a small town and there only one machine shop that knows nothing about honda motors. i can measuer it my self if i can find out the numbers. would a helms have them? the stamps are all seperated the only one that is together is A2 there is no pr4.

yea i think thats what im gonna have to do. some one has to have a for sure ls crank laying around.

 

i mean just put it in the block and crank it.. not totally assemble it

 

the LS journal is roughly .070 wider than gsr.

 

Measure what the stroke is.

Oh and also store the crank on its end not laying flat.

do you know how to measure the stroke? and yea i know i just layed it down to take the pic.

 

it doesnt take a honda person to measure stroke even an incompetant v8 redneck could do it if he worked at a machine shop, stroke is stroke regarless of v8, i4, or v16...

i know this but i highly doubt he will know the numbers between honda b series cranks. hes like a 70 year old dude at this old run down machine shop that looked at me funny when i told him i was building a honda motor but he can do the machine work for me. and thats why i need to know the specs so i can measure it my self. anyone?
