Ok guys I tried the search but didn't find anything. My 68 Lemans with 69 455 olds motor. Adding power steering. Have every thing pump and brackets box hoses etc. from a doner 68 Olds 442. I'm running the short water pump, I finally have the correct pulley set (thanks to folks on here). Water pump pulley KE 399401, Crank pulley KB 399402, power steering pulley KG.
I'm finally getting around to install everything, and I can't get the water pump and crank pulley on as they touch in the middle. I'm at a loss. The only thing I can think of is the water pump, maybe when installing it with the bolts the pump can actually move up or down on the bolts before tightening. I don't remember there being any dowels to keep it from moving up or down etc. I don't know if that makes any sense at all.
Or are there differences in the short water pumps from a 67 425 (which is what is on it), to a 68 400 short pump on snout position (up or down).
Any ideas guys?

 

Pictures would really help us help you. In the meantime, ALL Olds V8 water pumps have the pulley centerline in the same place. There are THREE different pump lengths.

Do you have both PS pump bracket spacers installed correctly? Obviously the pulleys cleared from the factory, so either parts are installed incorrectly or mis-matched.

 

I'll see if I can get some pictures. From what I've found on this site the only differences in the pumps is the snout length like you are saying.
The power steering pump isn't the issue, just the fact that the crank and water pump pulleys will not go on because they touch in the middle. The current pulleys I've been using with no power steering are the 67 Toro 425 pulleys (JE and JA), they are really close together when installed, but don't touch in the middle. If I lay the two crank pulleys one on top of the other the KB pulley is slightly bigger in diameter then the JA pulley, which seems to be the problem.

 

Sorry, I missed that the first time. Definitely one of the two is not correct. The pulleys are very close, but obviously do not touch.

 

"I finally have the correct pulley set (thanks to folks on here). Water pump pulley KE 399401, Crank pulley KB 399402, power steering pulley KG. "


There is a KB 2 groove crank pulley
399402, 6.4" OD, 1.25" 1st-groove spacing

and

KB 3-groove crank pulley
412235, 7.9" OD, 1.25" 1st-groove spacing

Are you CERTAIN of the PN's you have?
Because a 6.4" 2g KB should NOT touch the KE

There is also a
KE 2-groove 7.1" OD x 2.0-2.1 overall width, PN 399401

and

KE 3-groove 5.7" OD x 3.7" OAW, PN 409807 ?

Evidently you have the larger of each type then? [mismatched, and will contact]...

Photos, numerical measurements?

 

Ok here goes. First both pulleys are 2 groove.
The crank pulley is a 399402 KB I measure about 6 7/16"

The Water Pump pulley is a repop 399401 KE measures about 7 11/32"

Octania, just from what you're saying it sounds like the repop water pump 399401 KE pulley is too big. I don't have a digital caliper that goes big enough, but the biggest KE pulley you listed was 7.1". I think this pulley at 7 11/32" is bigger then that.

 

Agreed.

I hate fractions.
Why don't we just use fractional mm?

"186 & 17/32 mm"



I can measure a few OEM KE's if need be, but frankly, that 7.1" [around 7+1/8 if you are a tape measure user] came from me measuring these things, with a tape measure or calipers if handy. So, yeah, if the reproduction units are 7.344 [calculated from the fractional above], and are SUPPOSED to be 7.1" then that would be the problem.

Really hard to believe that a repro part got made not to spec, and no one ever bothered to ck the fitment and whatnot. That's never happened before.

 

Well if it ends up you have a straight KE pulley that measures 7.1" that you want to part with let me know.

 

I just found this on E-bay, a repop 399401 KE pulley listed at 7 5/8" diameter.
http://www.ebay.com/itm/1968-69-OLDS...ht_1455wt_1161

That can't be right.

 

7 5/8" diameter

FAIL

I will ck the supply
I think the only KE 2g units I have are chromed?

 

Man that's great, at this time I don't care if it's pink as long as it's the proper size and straight. Let me know. Thanks

 

Be careful what you ask for....

How they "reproduced" this and got 7.4 - 7.625" and called it OK is beyond comprehension:

We can discuss specifics via PM or text or maybe a voice mail bu I have 6 VM's now I can't find time to ck cuz I have to wade thru EVERY DAMN ONE SINCE DAY 1 to get to the recent ones... Verizon.... anyone got a trick to skip ALL of the old ones all at once? I know how to skip one at a time. Still takes a half hour.

PS all pulleys have runout or wobble. Do you have a numerical limit? 0.001"? 0.100" ??

 

Pm sent Octania. Thanks

 

Pulley shipped
make the repro sellers refund your money?

That's crappy to NEVER ACTUALLY TEST FIT THE PRODUCT.

Oh, btw, I never test fitted your KE

But, it's a factory OEM item.

I did ck the wobble and dount [FOUND - grrrr.. typing in the dark, w/o me reading glasses] it acceptable.

 

I'm sure it will be fine. I checked my invoice and it says no returns after 30 days. But I'm going to notify them anyway, and let's see what they say.

 

I work with manufacturing tolerances every day and that size difference has to be intentional. I almost believe that is how they get around the licensing agreement- by not making the parts correct.
A lot of this garbage comes in from China and is not worthy of riding in the trunk of an Oldsmobile. You should take pictures of how it doesn't fit, and send them to the vendor. Then, insist that you get your money back regardless of their return policy.
I hope to hear that you have it running soon.

Also, do everyone else a favor and let us know who you purchased this incorrect part from.

 

Yeah, it doesn't grow, does it?
So, it was not going to fit right, EVER. Before or after 60 days.
The correct thing to do is to SCRAP and DESTROY the incorrect pulleys so that others are saved this grief.

Unless perhaps there is one smaller mating pulley for the crank that might make it work. Smaller than 6.4" though? Let's see...

KJ at 6.2" OD, but that has 1) incorrect offset from mtg surface to 1st groove, and 2) fatter space between sheaves as befits pre-68 units.

JA at 6.25 dia. perhaps, has the right 1st-groove offset, but, again, being pre-68, will have the fatter groove to groove spacing.

So, no, there is no factory pulley that will work with an incorrect KE having a diameter over 7.12".

I would like to see photos of the too-large KE and the correct crank pulley, showing the interference and how they DO NOT WORK.

And, if these are being sold via epay, then the epay feedback should accurately reflect how well or poorly they fit. That way others won't get burned with crap that does not fit.


What, not ONE comment on my "11 digits of accuracy" in measuring the OD of the OEM KE pulley shown above?

:-)

 

We expected nothing less.

Snarkasm alert!

did you notice I worked "1968 442" into it?

that's my CO password, too!

 

I bought the one I have from "The parts Place", there website online not through e-bay. I figured they all get these from the same manufacturer, I might as well go for the best price. I see that Supercar Unlimited list one as well. I wonder where they get them from, and what the outer diameter is. http://www.supercarsunlimited.com/Wa...ley-d2344.aspx.

 

Fusick's Oldsmobile also lists a 399401KE pulley. Part number WPP68. No listing of outer diameter either. Page 44 of there catalog.

 

Ok gentlemen I have the correct pulleys (thanks to Octania), and know have the power steering on and working great.
I now have a call in to The Parts Place, to see what they are going to do about the repop water pump pulley KE 399401 that I got from them that was too large in diameter. I'm going to send them pictures tonight of there repop next to the factory pulley I bought from Octania. They said they sell alot of these and I'm the first to say that there is a problem with the size.
I'll let you guys know how this plays out.
