np 435 conversion wtf

[angrytodd]

I got the parts from jeff the adapter is not bolting up ther is a gap at the top of the adapter with the bolts tight you can see the top bearing a 1/16 gap
looking down from the top

Something is binding..
Did you cut off enough material at the end of the output shaft?
Maybe the bolts are too long and bottoming out?

 

[68 Broncoholic]

Yeah, you need 1" cut off.

I did the conversion and I had no problems with a gap on top. I did not cut off the shaft. I got the intermediate housing and the 1" adapter plate and was good to go. Never heard of cutting the input shaft 1". Tim

I just installed a 2wd NP435 this afternoon. I also did NOT cut an inch off the output shaft. I used a 6 cylinder intermediate housing and spud shaft. Also used a 1 inch adapter plate. It all fit with no gaps and nothing hung up...

I did not use a spud shaft. I did not need one I thought.

so what is the p/n on that plate? and where to get? if you dont mind me askin?

 

[Madgyver]

There is a threaded section on the short 2WD output shaft that needs to cut off to work with those aftermarket adaptors.

Again, I did not cut off the threaded portion of the output shaft, and it fit just fine.

Shaft Cutoff

Yes My Running Buddy And I Did Our About 2 Years Ago And We Both
Cut Of "as I Remember" About 1/2 To 1 Inch Off But It Was In The Instructions In Our Adaptors...

I made the cut also. I did a dry run on my bench prior to the install and it was obvious I needed to remove some material off of the shaft.

I had seen conflicting reports of a yes cut, and a no cut.

I cut. No problem.

 

[mudstud]

I used the intermediate housing adapter from JBG and I removed the treaded section from the output shaft. I also did a bench fit like ManTruck and everything went together fine.

I used a 2WD NP435 with the square bolt pattern.

 

[angrytodd]

I got the 4x4 435 and changed the mainshaft that is not the problem the adapter is not welded square and ther is flux on the in side of the weld that can get in the tranny and the t case I am sending it back to jeff's
let you know what thay tell me

Yes, but you are using a plate, not one of the adaptor kits.
