Swapping engines

[maxnine11]

Have been following along your journey with great interest.
Glad to hear that you went with The Solution instead of the other options.
(That is what I chose without hesitation for my car) Pay once-cry once or whatever that saying is.

But, it is a "plain bearing".
Not a bushing.

Best of luck with the rest of the journey.
The best part of Boxster ownership is driving the car. Hopefully the car rewards you for you perseverance and investment!

cheers

Hmmm... Jake Raby or Charles Navarro referred to it as a bushing in one of their videos. It sure looks like a bushing to me. JFP?

That aside, thanks for the kind words.

While we're on the subject...

A Kansas-based company named Huyett supplies a huge selection of bearings, bushings, and fasteners of every description for a multitude of applications. They consider bushings and bearings to be fasteners... which spins my head around. Anyway, they weighed in on our question on their site:

Bearings and Bushings: The “Difference”

Many explanations will simply state that there is no difference because a bushing is a type of bearing. While this isn’t untrue, it is a surface-level answer because it invites the notion of, “if A is B and B is C, then A is C.” In other words, if bushings were a type of bearing, then subtypes of bushings would also have to be a derivative of a bearing, which isn’t true. Bearings are not the “parent” part.

Bushing is more of a generic term that catches most of the single-component members of this fastener family. Many bushings bear loads or allow for rotational movement, and many bearings reduce friction; all of these parts will alter the size of a bore. So why even distinguish between the two?

There are a few specific fasteners that are definitively a bushing or a bearing based on the definitions above. Beyond these few, the difference between a bushing and a bearing at a practical level is how it is used, not how it is designed. Since fastener manufacturers, distributors, and hardware stores cannot predict how you will use a part, their names for the fasteners are somewhat arbitrary.

Interesting, huh? Just out of curiosity, when I get a chance I'm going to email Huyett and ask them what they would term the Solution's application in M96 engines.

EDIT: Emailing them was a good idea. Unfortunately, I didn't anticipate that Huyett would have no email address. That's what you'd call "old school." I guess a website was leading-edge enough for them.

Mechanically, it is a bushing that is serving as an oil fed bearing.

Generally, if there's high speed and/or high load its called a bearing. Think main and rod bearings. They are really bushings, but given their application they're called bearings. The same would apply to the solution.

Think of the small end of the connecting rod on an old style V8 engine: to allow the piston wrist pin to properly float, the small end of the connecting rod has a bronze sleeve bushing pressed into it with annular oil groves in it to permit lubrication; when in operation, that sleeve becomes an bearing.

What it is is all a matter of semantics: a mechanical engineer would call the Solution a bushing because of its design features; in function, it is an oil fed bearing.

I measured and marked the cutout for the notch to my satisfaction. It's 20mm wide, which provides room to put a 13mm deep socket on the oil fitting. Note my aforementioned patent-pending seal for the opening, fabricated from thick, extra-sticky Gorilla tape. How sticky? It took a lot of pulling to peel the prototype off. It seals the opening tighter than a bull's rear end at fly time (one of my dad's expressions, approximately). Not a chance of aluminum particles from grinding getting past the seal, but as belt and suspenders I stuffed a paper towel in the opening before sealing it. I'm ready to grind the notch. Unfortunately, that will have to wait until tomorrow due to a previous commitment.

Exactly: All a matter of semantics. Like I said about main and rod bearings. They're bushings, but given their application they're called bearings.

I'VE GOT IT! It's a bearinglike bushing. Or a bushinglike bearing, take your pick. Whichever it is, it's unlikely to fail, and that's all I care about.

Not all bushing are bearings, but all bearings are bushings
