    To be clear, when I set bearing preload on a hub I usually tighten the castellated nut until it is firm (ie: hub doesn’t freely spin), then alternatively loosen & tighten the nut progressively until the hub spins freely but with some resistance. Then the nut gets tightened until it aligns with the next split pin hole.

    My question- is this method correct for both styles of bearing (I am referring to the front hubs on my ‘61 Bonneville)?
     

    Yup, I got that. And you are 100% correct with regard to tapered roller bearings. That said I must plead stupid with regard to ever seeing any old school GM rear wheel drive cars that used a ball bearing arrangement for the front spindles! As I indicated a few posts back, it looks as though someone modified that hub. So my point is that you do not install two opposed ball bearing on a shaft, in this case a spindle, without a internal sleeve that runs between the two inner bearing races & that sleeve can’t compress. So when you tighten the nut you tighten it to a torque spec & leave it there. Just like you do for a front wheel drive cars front hub. This is because of how the construction of a ball bearing is designed vs a roller bearing. I just what to make sure I understand what you are precisely asking, as I don’t want to steer you wrong.

  2. Well, I hear what Kiwi is saying & I’m not saying he is wrong, because I’m not clear on what is implied. So I would need a better explanation of what you are doing.
    A front spindle bearing that takes a tapered roller bearing is set with a preload in a certain way because the races are tapered. So you are actually loading the rollers between the two tapered races of each assembly. While a ball bearing, bearing is already assembled & as a unit already loaded since it is not tapered. The preload on ball bearings to each other, like a hub, that is set in a manner that only loads the two lower race, without any movement of the actual races, against each other. If you do it any other way, you are setting the balls of the assembly in shear against the upper & lower races of its respective unit. 
     

    Just trying to make sure I understand what is being asked!

    My next issue is that this is a 63 block 

    it doesn’t have the material like 64 and onwards  for the block mounted starter motor . Which is going to be an issue with me wanting a over drive trans !! 
    more research required I feel ! :cheers: 

    I’m not doubting JustA, no doubt in my mind what he says is how this is viewed and dealt with! But this is kind of what I got paid big bucks to do! Figure out how to do something that wasn’t supposed to be able to be done. So while I’m a bit familiar with the issue I’ve never seen it. So Kiwi if you can show me some detailed picture of the issue & the differences I’ll see what I can shake out.

  4. Kiwi, not enough time to get in to it right now but a couple quick things! The 3800 that is in the Grand Prix (1997-2003) is a low profile supercharger that uses a thin lower manifold. So I would tell you that with the right mods you can do it. Also, those finned valve covers are somewhat rare & renewable.

    I like the 2 leg look more. I don’t know if it’s stock but it didn’t come on my car so I’m trying to find one and all I’ve found so far are really shady websites.

    No that’s not a stock spoiler for a 1997-2003 GP. There were only three, than there was a couple aftermarket ones, none of which looked like the one you show. That particular spoiler looks to be from the 1988-1996 gen. Which actually didn’t appear till the later part of that generation. Could you adapt one of those to be what that one is? I can’t say, never looked at the dimensions of it. It could be a aftermarket that I haven’t seen as well.

    He hasn't been here for 19 hrs.  Talked with 360 Rocket, lotta downed trees to clean up, but they are OK.  My sons shop is flooded in Orlando, but only to the bottom of the cars he's working on.  No damage, lots of limbs N tree's down too.  Water came close but never made it to the house.

    Looked like Naples got hit pretty hard with flooding. Hope he was spared. Over 2 million without power, last night, might be more now.
