Issues with the t/case encoder motor line up after reuild ?

Issues with the t/case encoder motor line up after rebuild ?

For the previous post you know I have removed the encoder motor, and used a 15mm crescent wrench to manually shift the shaft on the t/case into gear, to get the tranny operating. Gears are now working fine.

New problem, encoder motor wont go back on so easily as it did when newly installed.

It seems the line up between the motor and the t/case shaft is not quite matching, for the motor sit flush against the t/case and for me to install the 3 bolts.


I tried several things.
1st was to shift the e/motor shaft on the t/case to all 3 positions and put it on. But that didn't work. (By the way what are positions 'A' and 'B' ?)



2nd was to loosed the tension spring enough to allow the shaft to be loose enough to match it up with the encoder motor , then bolt it up, but that also didn't work.

There is a misalignment between the 2.

Is there any other way to get this thing on without opening up the encoder motor or the t/case ?

Any help will the appreciated.

Things are going crazy now with the t/case out, its surging and cutting out.

OK, how about this option.

Reconnect the eletrical connections for the force motor.
Turn on the car, select a setting, say 2HI.
Then I can manually select the position on the t/case shift shaft and line it up.

Would this work or not?

Another option

I found this on a different forum, where it talked about replacing the sensor in the encoder motor. its a different encoder motor i think nv263 not the np246 I have.
it reads:
"Important: Observe the location of the punch mark on the large gear in relation to the timing mark on the housing if the transfer case was placed in the 2HI for the NV263 (NP1), or Neutral for the NV246 (NP8). The timing marks should be within one tooth of proper alignment. If not, you must note the timing mark positions for reassembly". the timing marks are marked in red.



So if I open her up align the marks and put her back together should this work ??

i have never had one of those things apart and i doubt few here, if any have.
about the only thing i can recommend is to plug in the encoder motor and, with some help, have someone push the button for the separate ranges. once you find which is what, and know physically what range the t-case is in, you should be able to just bolt it up once they match

Ok so as my first suggestion:

- Raise the rear end and peg the front tires.
- Disconnect the battery to clear the TCC.
- Reconnect the force motor. letting it hang from the t/case.
- Turn on the vehicle and select the correct range, with the tranny in neutral.
- If the force motor lines up, turn of the vehicle, bolt it up.
- Turn on the vehicle again and leave the transmission in neutral.
- select the various settings on the t/case.

Does this sound correct?

Piece of cake!, thank God for that !

it was so easy, clipped it in, went up , started the truck, selected Hi2, (it was in LOW4), heard the thing clicking and switching gears.
Slipped her one, and bolted her up.

Thanks for the help man.

Master Mechanic, I am only the apprentice who was give good advice.

This truck is now chirping the tyres from 1st to 2nd on light throttle with a really firm bang like shift, Is this normal or what ?


I all wanted was a reliable tranny not a beastly 4l60e, but I'm not complaining.
