i have been reading other post on the forum which are very helpful, but Im very unclear of what i have here but here it goes i have an 1970, olds 442 w30 i had the engine rebuild years ago the M22 i had in it went out i bought a new manual trans for it but I'm having trouble with the pilot bearing i have pics but the two bearing i ordered for that car are to small the bearing i cut out is about 1.7 inches tall the one i ordered is 1.4 please help me find out what i have so i can get the right bearing cause its come to my conclusion this is not my crank.

First glance looks like you've got the fix-it bearing to install in an automatic transmission crank. Here's a link to an old thread that has pictures and details on how the crank should be cut for a factory pilot bearing or bushing.

I got to thinking... do you still have the bad transmission? It may have had the input shaft cut short if you do have an automatic crank in your engine.

John

this crank is already in the engine I'm trying to locate a 1.7 bearing to put in it. so what you are telling me that this is a automatic crank.

walkerse

it still has it, the tip of it was untouched.

2blu442

OK, good so you have enough depth in the crankshaft for the input, but not the diameter for the standard bearing or bushing.

Supercarsunlimited has the bearing you probably need. Here's a link to their web site:

WAIT it has been cut (the old one) just by me looking at the new one. the new one is much longer.

2blu442

Well, you've got some choices. You could re-use the shortened input shaft from the old transmission. Bob the end of the input shaft on the replacement transmission. Drill a deeper hole in the crankshaft... not advised without removing the crank and should be done on a lathe rather than drill. Cut the crankshaft with a lathe to use the factory bearing/bushing if you end up pulling the crank.

The search function here isn't the most user friendly, but this issue has come up several times in the past. You could read through post of what others have done to deal with this situation.

so i cant use a drill to go further inward.

2blu442

Well, I've known one person who has done that. The risk is if you don't get it perfectly centered then the crank will be out of balance. So I wouldn't recommended it but that's your call on if you want to give it a try or not.

i dont think i want to take that risk... thanks allot you've been a big help.

I got so focused on the question that I forgot to say welcome to the site! There's a few other members here with 1970 W30's, I'm not one of them but I'd enjoy seeing photos of your car when you have time.

2blu,
i have another question. i just received the right pilot bearing for my crank just want to ask am i suppose to put any type of thick grease or lubricant in there with the bearing.
thanks in advance.

2blu442

No, the bearing should be tapped into place with a large socket or something similar that only presses against the outside ring of the bearing. The ***** in the bearing are fine the way they come out of the box.

2blu442,
got another question. i ordered a keisler trans for my Olds442 having an issue with the cross member have you heard anyone having the same issue? did they replace the cross member? or have to modify it some way?

2blu442

Sorry, I'm not familiar with that transmission. You might create a new thread asking who has experience with it. Is the location of the cross member the problem, or does it have a mount that won't fit on the cross member location? If you could mention that and even add a photo if possible that may help others provide the info you need.

Okay guys I'm back. Right now I have a demon 750 on my 455; the Demon needs to be rebuilt. I'm having a lot of issues with it. I'm considering replacing the demon altogether. Anybody have any ideas on what is the best carburetor to get for these old school cars.

oldcutlass

What intake is on it? If it's set up for a spreadbore, run a Rochester, if not then a Holley or rebuild your Demon.

walkerse

the Edelbrock performer intake.

oldcutlass

You can run any carb on that manifold. I can't run an Edelbrock on my car due to clearance issues and the lack of drop base air cleaner availability. I've been using a Holley 3310 and it's performed flawlessly for the past 2 years. The Holley 770 Street Avenger has been popular on other sites. I also like Rochesters, they are economical to run and sound awesome @ WOT. So it really boils down to your personal preference.

Why not rebuild the Demon?

walkerse

I really don't know what's going on with my car. It runs but the engine doesn't sound like should I think it's between the carburetor and the timing. The car will run, it starts up with no problem, but during idol it doesn't run smoothly. At all.
