Pilot Bushing ? for the masses.

[SquareRoot]

Bushing-bearing whatever. What I want to know is under what condition does the input shaft turn at a different speed than the crankshaft? My Goodwrench motor came with a bronze bushing. My Clutch came with a roller bearing.

What say y'all?

Any time the clutch is depressed, the input shaft and crank turn at different speeds.As for preference roller or bushing I don't really have one, I've seen both fail and I've seen both last for decades.

I think the depth that your trans input rides in the pilot is the most important.

The thing I liked about the McLeod bearing that came with your clutch was the depth front to back. It has that collar that bottoms out on the crank for added input shaft support.

With the standard pilot bushing, you don’t necessarily drive it all the way into the crank. You’re supposed to check how far the input shaft goes and possibly not press the bushing all the way in to increase support for the input shaft.

That's kind of what I was thinking. So I'll assume that sitting idle while holding the clutch in causes excessive wear to some degree, the TO bearing and the pilot bushing.

Yep. You are supposed to sit at the light in neutral.Its also hard on the thrust bearing

@Frankenchevy ,

I checked that, but decided to leave the factory bushing in the crank. The bushing was flush with the crank flange surface. What surprised me was that there was like 3/8th inch more space behind the bushing. I was surprised the bore was that deep.

How did you know what bearing, bushing, and clutch kit he has?

Did you not put a new factory bushing in?

Lol. He's a stalker

LOL. Really I did.

I was at Wal-Mart I kept seeing this same woman in every aisle I went down I looked at her and said geez ,I go to Wal mart and end up with a stalker. She says it's funny when you say it, when I say it, security takes you out of the building.

Nope. It's a new crate engine that had an auto in it. The factory bushing was still new. Just a little lube and in went the shaft....input shaft.

He ordered the same one I got. HE is the stalker!

I’m sure you’re fine either way as long as you aren’t in the habit of sitting on the clutch at a stop.

Bushing for an automatic, bearing for a manual. That's what I've been told. My manuals have bearings and I've never had a problem. Never had a problem with bushings in the auto vehicles but why take chances?

 

[Ricko1966]

Wait until the day you go to do an auto to manual swap or swap a used engine in and discover its not machined for a pilot bushing. It happened with a 455 olds had to take the crank out and have it machined for a pilot bushing.
