Replacing encoder motor procedure

[wagslick]

I've got a 99 Silverado 5.7 L and i'm replacing the 4wd encoder motor at the transfer case. I just can't seem to install the new one. I'm thinking I need to line up the male part pin on the transfer case with the female end on the encoder motor. How do I turn that pin on the transfer case so the two line up?

put the old encoder motor back in . using the 4wd switch place the transfercase to neutral . then try to install the new encoder.


THE NEW ENCODERS COME POSITIONED IN NEUTRAL.


IF THE OLD encoder is inop then jack up rear wheels off ground tranny in neutral , rotate drive shaft then try to rotate the transfercase slot.


the encoder motor has 2 heavy guage wires these go to the motor . if all above does not work, then using fused jumper wires carefully apply power to the encoder motor wires for a very short time 1/2 second ,as you watch the motor rotate .


connector C1 pin A is the blk wire, connector C1 pin B is the red wire. you can put positive on blk or red . this is how the motor reverses direction normally. doing this manually for a very short time you can safely rotate the encoder to the correct position..

after this is correctly aligned then install the gasket in position for permanent mounting.

connector C1 pins D and C are the locking feed to lock up the motor ,,don't mess with them !

connector C2 this is the feedback to tell controller where the transfercase motor is in its position............
