I bought a 390 flywheel and clutch set and put it behind my 460. Having a problem get the trans to mate up to the engine. I used the bigger 390 pilot bearing. I had bought a 460 pilot bearing but it was nowhere close to fitting.

Will I have to find a different pilot bearing?

 

Their is reveiws all on this ,I beleive Bronco just did alot of reserch and input into this dilema a 302 pilot bearing ck it out

Ok, so I've searched for this, and only found that a 302 pilot will work? But is this for T5, or older T18 or 19? I have the right T18/19 400m bellhousing, just need the pilot. The trans.is now bolted to 390FE, and I was planning on using the clutch and flywheel from 390.

The 460 is out of 77 econoline van, so it should be internally balanced. 390 and 4spd, are from late 70's F100 or F150.

I know the best way is to measure trans input shaft outer diam./ engine crank inside diam. And go from there. I was hoping someone has done this and knows, to save me time. Thanks in advance NP435 Bronco

 

You got the wrong one. Go back to parts store. When we looked them up in the parts store Dorman had 2 listed, one big one little.

 

We had the small one but it didn't fit.

 

i bought a non roller bearing pilot bearing and had a machine shop turn it down to fit deeper into the 460 crank, this allows for the connection of the engine and transmission to fit without the need of any shim plates.

 

do i really need this pilot bearing?

 

Yes, you do....
The pilot bearing supports the end of the transmission shaft and you can't run without that support. That is without breaking.....
