Hi everyone, i had a few questions about my crankshaft.

First off, i just rebuilt the engine about 500 miles ago, it was running very nice, with no problems until one day the crank pulley ( harmonic balancer) came off. The teeth on the pulley and key-way in the crank completely stripped. It is not repairable and i had to buy a new crank.

Today after looking all over and calling many places trying to get a remanufactured crank online and at local parts stores, i found that they were all out of stock, and so i went to Craigslist and found one for sale. I went 3 hrs out to buy this crank and pulley today. It was in very good shape both the crank and pulley. However, there are differences between that and the original.

1. The new crank has a smaller snout (where the pulley goes on to). I put my original gear/sprocket from my original crank that the timing belt rides on onto the shaft and it just goes right on with ease. Not too much wiggle, but compared to the original crank i had to use a pulley to get it off.

2. The crank pulley/harmonic balancer is smaller on this new one than my original pulley

.. So, i was aware that 2 sizes were offered when buying a new or remanufactered crank, both cranks have the same rod diameter and main diameter, but the snout size is different. My original crank was a .944" and the new one is the other size.. the .8xx" .. Can i still use this crank?
Is this from a 1.6L engine? maybe a D16z6?
He said it was from a 1995 1.5L singe cam.
I have a 1993 1.5L single cam D15B7.

If i get a new sprocket/gear that is behind the harmonic balancer that runs the timing belt to match the new crank, are they the same as what i had before besides having a smaller diameter center hole, or is the overall sprocket smaller or bigger. If so, wouldn't that affect timing? possibly the crank is for a dual cam?

Any help i would really appreciate.
.. I sure hope this crankshaft will work, i don't know what i will do if it doesnt. I need my car working again
Thanks,
Dan

Any ideas you guys? Maybe the crank is a .944.. i havnt measured it yet. the sprocket does slip on with ease and there is only a very very small wiggle that would seem normal. But i remember getting the sprocket off of my old crank that i had to use a gear puller to it. Should it normally slide on and fit in easily? or be plastic hammered on. This is the sprocket, not the harmonic balancer i am talking about.

Also my new harmonic balancer is a little smaller than the original one.. Ideas if this crank can be used for my 1993 civic D15B7?

i am 100% sure u have to have a crank for what ever motor u have, either the rod or mains is diffrent size on the d15b7 than the d16z6

dtk132

^ pretty sure i have to have a crank for the right motor i have? really?

i am pretty aware of that. I know the d16z6 is completely diff from the other cranks, but they did make a crank the same size main and rod diameters as what i have but with a different (smaller) size snout. Thats where my question is. Why did they have 2 of the same crnaks with 2 diff size snout. the .865" and the .944.. Again, I originally had the .944
So if the only difference is in the snout size, would i still be able to use it with the sprocket i already have even tho it is not a tight squeeze on.. or will i have to geth the smaller sprocket to fit the .865 .. if so will the overall gear be different and effect the timing

jdmh22eg2

well the sprocket for just the balancer will not effect timing how ever if the oil gear snout is diff than that i will effect ur timing belt length

if the rods and main mic out the same as what u have then i say just go to honda or find the correct .865 balance pulley and call it a day (u may have to get diff length ps, ac, alt belts)

u dont want ANY play in snout to pulley play what so ever i forget the forumla for speed vs imbalance but from 2k rpm on up the imbalance goes up exponentially for every lbs of imbalance

I already have a .865 harmonic balancer to match with the new crank. How would having the smaller snout affect the length of the timing belt?? What i am saying is the sprocket/gear that the timing belt rides on, if that is different overal diameter and teeth count than the sprocket on the .944 crank. If they are the same and the only difference is that the sprocket has a smaller center hole to match with the .865 then there would be no difference in timing belt length..
This is a serious question.

i dont mean to come off like an a** about everything. but these little honda motors seem to have the same common problem at the crank snout from 92-95. If you look it up or even google it you will find it is a common problem. When someone else gets to a point like i am in, they will see this post, and will not only help out me but whoever else it has happens to. They need to know the difference in the 2 cranks available because sales people do not explain this. why they offer the same diameter main and rod cranks but with 2 different snouts. .865 and .944

If someone were to have the wrong snout, like mine for say.. and it being the smaller one, is it interchangeable?
Is the only thing i have to worry about is getting the new sprocket to match the smaller .865 crank and will it work with the rest of the motor. Its avery straight forward questions i have been trying to get across.
Any help on this topic will surely help me and others later on, being as that i cannot find anything in detail about this subject. Most will post idiotic replys of what they THINK, rather than what they know. Or just simply by replying get a new motor.
Thanks

Also to add, someone changed my title. Thanks it makes more sence but please dont change the words, because what i am asking does make sence it should be usefull for others looking for help on this topic. Thanks again

NOT SURE WHAT OTHER ANSWER I CAN GIVE THAN THIS

and how would it not effect ur timing belt length if u have a smaller/ larger crank snout for a oil pump gear(ur belt rides on) if the OD of shaft is smaller than u will need a smaller oil gear, and vise vs. for larger so then u would need a bigger/smaller timing belt

basically u will not find a oil gear with same OD and same # of teeth and fit a smaller/ larger snout if u change ID 99% of time it changes the OD and teeth # on the gear


Also u are taking the word of some kid on CL u REALLY dont know what crank u have FOR SURE

I dunno why but honda doesn't list crankshafts for sale, i dunno why, its in the diagram, hell its even numbered but no part number otherwise i'd compare them for those years. Only other thing I can think of is the ones with a 2 belt crank pully (no P/S) had a different crank than those with a 3 belt crank pully (with P/S)
