Planning on removing the faulty encoder motor from my K2500 2003 Suburban, (transfer case model: 246), in order to manually adjust the transfer case's cam into 2Hi, from the present 4Hi setting. Don't plan on using the 4wd anytime soon, and therefore want the transfer case to focus 100% power to the rear axle. Would anyone have an answer to:

a) The direction of rotation to the transfer case's cam, to set it into 2Hi from 4Hi; clockwise or counter-clockwise rotation?

b) How many degrees of rotation would be needed to achieve the desired result?

c) How many ft-lbs of torque could be expected to make the adjustment using a socket drive?



Thanks in advance.

cant remember which way for sure but as long as theres no torque on the driveshaft its not that hard to move the shaft,your vehicle has autotrac if its a 246 that encoder has a postion where it preloads the clutchpack and the shift shaft moves back and forth some without ratcheting,Im pretty sure that you would move it back,wrench or pliers bottom would move toward front of truck.what are you going to do with encoder as you cant turn it manually?

I would like to service the encoder by replacing its internal position sensor, as opposed to replacing the entire encoder. Came across a bulletin explaining how to service it, omitted to bookmark it though.

its not hard to replace the encoder sensor have done many,do you have a c0327 code set?it could be the encoder or about a dozen other things Ive found.one of the more common ones is the ground thats on the body mount frame support under the drivers feet.there are two grounds there ,the one on the inside is the tccm ground but it doesnt hurt to clean both and replace the bolts also,engine block grounds can cause a problem as well.from engine to frame and frame to body,if all are not good tccm can backfeed looking for ground and usually ruins encoder sensor.

Thank you for tips. Yes to the C0327; I'll give those grounds a look b4 proceeding with the EM.
