remove oil pan 425ci cadillac 1977

[Crys59]

Is there any rod bearing at 0.06 ?

if yes i can machined my old crankshaft

[The Tassie Devil(le)]

the 425 crank is definaitly cast iron .but then i have seen welders use iron rod in an industrial setting

Thanks for that Bill,

The last Cadillac Crank I dealt with was the one in my '60 390, and that was Forged Steel.

Seems like Cadillac finally went to the cheaper Cast Cranks to cut costs.

they were made out of a better grade known as nodular iron like some pontiacs and a few chevys but still cast iron none the less . it was a difference in the shape of the carbon in the iron, balls instead of flakes  making it more ductile

do you know if the 0.06 exist ? please

[The Tassie Devil(le)]

I believe that 0.040" is about the largest undersize replacement bearing shells that are available.

If it has to be ground to .060, then I would be very suspect as to the strength of the finished shaft.

If it has been subject to any hard treatment at the factory, then .060 will virtually remove any that might be left.

One other note to help you i your search, the 472, 425, and 368 crankshafts can be interchanged. You may want to have the rotating assemble balanced if you use a 472 crank since the pistons are heavier, but it will work if you can find one.


I see Stan has three listing right now
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=130090204692
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=130090205167
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=130080550353

He lists the weight at 74lbs. Contact him to see if he'll ship to France.

Maddog has this one
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=220193643395

They do state they ship outside the US too. The shipping calculator shows UPS to France at $425.
They may have other options though.

One more option I see this morning

[Crys59]

thank you for your help because the barrier langae is a big difficulty for me

are you sure this part http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7999358614 is the same than the 425ci ( year1977)

if yes it's a good news for me, what is the good bearing size  for this remanufactured crankshaft (0.01?)


thank you for your reply

[STDog]

are you sure 368is the same than the 425ci ( year1977)

if yes it's a good news for me, what is the good bearing size  for this remanufactured crankshaft (0.01?)

Yes. The 368 and 425 crank shafts will interchange, as will the 472 crankshafts.
If you compare the first link and the last link you'll see that have the same casting number, #142 listed.

Any bearing size is fine. The less under size the better, since it leaves more room to regrind later, but you won't see any difference in use. Usually, the larger the grind, the more damage was done and needed repair, but again, I'd have no problem running a 30 or 40 under crankshaft.

Note that the Maddog Racing listing includes the bearings in the price, while the other don't include the bearings (but they sell them). Note too that the bearings in the last listing (Allstate Engine Parts) will fit the 425 (and 472 and 500) even though the listing only mention the 368. Check to see what brand they are first though, as the part number doesn't match Clevite or SealedPower numbers.

Did Stan ever get you a quote on shipping? (I saw your question on the first one I linked).

You might do better to get all the parts you cn from one vendor too. won't cost as much for one shipment as it will for several shipments.

it's seem's to me kanter sells rod bearing in 0.06"  and my crankshaft is 2.443 ...
is that possible to machine? no ?

but i have other ^problem with this crankshaft and connecting rod.
the axial play is very important. question: is it the conecting rod used or the crankshaft used?

thank you again for your help

What do the main journals measure? If they cannot be cleaned up to an available size the rods won't matter.
I know MTS(www.500cid.com) was working on 0.060 rod bearings, but I don't think anybody had bigger mains planned in the near term.

Not sure what you mean here. Fore to aft play in the crankshaft?
That's controlled by the thrust bearing, which is part of the center main bearing on this engine family.

[Crys59]

axial play is "connecting rod side clearance " in the repair manual

bad news , kanter tell me "0.06 not available"

You know or find rod bearing in 0.06" please ?

[STDog]

Ahh, That's usually adjusted by narrowing the connecting rods.

I suspect because it's easier to sand/grind the flat side of the rod that it is to widen the round journal.

But It might help maintaining the strength of the crankshaft.

[Crys59]

in fact the clearance is to high

[STDog]

in fact the clearance is to high

How high?

The high performance people recommend higher clearance than the factory spec.
30-35 thousandths (0.030-0.035 inches).

[Crys59]

on my engine clearance is 0.039.
do You know if it'spossible to  find rod bearing in 0.06" please ?

Check with MTS,  Torque Inc. or Cad Co.

I know TI and MTS were expecting to have them by now.

[Crys59]

MTS tell me "0.06 is not available, only 0.03"

G'day Christian,

Correct Side Clearance on Connecting Rods, and other areas where Oil Lubrication is required, is extremely important.

Too much Side Clearance, and the oil will simply squeeze out through the gap, and fail to do its' intended job of keeping the metallic surfaces form touching each other, and wearing away.

Too little Side Clearance, and the oil cannot get out fast enough, leading to the oil being retained, heating up due to friction, and eventually "Locking" up the moving parts, and that usually results in a spun bearing, which both wrecks the Journal, and the Connecting Rod.

Too heavy an oil can do similar thing, and is what could have happened in your engine to cause the problem in the first place.

I would be taking your parts to a reputable engine repair and machining shop in your area, and getting them to inspect, measure up, and advise just what parts you require to get the car back on the road.

The Internet is a wonderful source of getting correct information, but sometimes, a "Hands-on" experience is not only warranted, but a necessity.

Bruce.

[Crys59]

ok thank you i understand.
the big problem is for shipping a new crankshaft

[STDog]

Another (short term) source...
http://www.jalopyjournal.com/forum/showthread.php?t=240716
He lists two 425 cranks and a 472 crank. $175 negotiable.

Might be able to work a deal with him, considering the ship to address
