Pilot Bushing Or Bearing
« on: February 20, 2016 - 05:57:05 PM »
I'm having trouble getting a pilot bushing to fit like it should and I have no idea why. I've ruined 2 already and I've put los of them in before.


I'm considering a pilot bearing.  is that the way to go?   I have no gripe with the bushing I just can't get one to fit. 

I'm working on a stock steel crank 440 with a stock 833.

I just put a bushing in my hemi day before yesterday.  Is the crank an hp crank?  only hp cranks are deep enough for the bushing. Even if its an automatic car, if it's an hp engine it is drilled for a bushing. Then, The inside of the crank has to be clean with no rust or burs, also it is interference fit. It can not fit loose, or you Will have a serious issue in less than a couple of shifts. Then, You use a bushing install tool. You can use a socket, but I advise against it. Also look at the bushing ( Usually Dorman brand) it has a beveled edge, it goes out. Helps when you are installing the input shaft on clutch installs. Once you install the bushing DRY, test it with your clutch line up tool. I use an original input shaft. A lot of people don't have them just lieing around though. Then, to make things nice, you could use the bearing as well, but in the long run, they seem to put a wear cut on the input shaft in my experience. You also have to make sure the register has zero nicks in it and zero rust and install it correctly. 

Kinda like that dang cam degreeing huh?  lol. Muscle cars are a hobby now. Back in the day, when I was young, it was our transportation. Do it once, do it right, enjoy your car. Then another items lets go. But our stuff is 40 yrs old.  You need to learn the right way, or you will have to pay un nessessary money to a person that thinks he is a heart doctor.    ALAN

The one I just tried was an FM.  maybe they are looking up the wrong number I have the specs now I can check one.  it fit lose on the input which is to be expected, but once installed I couldn't even fit the input in after lots of sanding. it's WAY too tight.

This is a forged crank and it has the deep hole. it does seem awful rough inside though, more than normal.  this crank came out of an auto trans car and I don't think it's ever had a bushing in it.
