  • Which Transfercase do I have??

    Tammy has a 72 Scout II. I don't know a lot about it yet I do know it has the 304 w/holley 2v 4 speed which 4 speed I haven't a clue Mark and I figured out it has a Power-Loc 3:73 rear. My question is which transfer case does she have. And what's the max speed can she drive it in 4 High. We now have about a foot of the white stuff in the yard and she's been using 4WD she's leery of it right now until she get's used to it in the snow so she wants to run 4 High all the time but I don't think she can. Am I right? I know my truck, the Yellowdog, can't cuz it's a divorced 205 with straight cut gears. I'm rambling anything you all might tell me will be a help, Thank You

      NP205

      The NP205 I'm told has straight cut gears (it's in a 67 1200B P/U) and at 30/35 mph it wines real loud. I just use it to get me moving or climbing hills.

        Should have the Dana 20 transfer case just like mine. I run four high at highway speeds no problem they are designed for it.

        Like Jon said matched tires and the roads should be wet at least. I have also left the front end engaged highway speeds on dry pavement with the transfer case in two wheel drive. No Problem! She's going to like the 4X4 with the powerlock.

        Not sure about your NP 205 sounds like something is wrong there...:confused:

            NP 205's are a bit noisy, but it is usually the oil that causes that noise to be louder or quieter in my expericence.

            NP 205's can be run at any speed, but they become a bit loud at speeds about 55 MPH. At least the ones I have had.

            With regard to you Scout II transfer case, the only way to be truly sure is to take a magnet, and stick it to the tailshaft of the Transfer case. If it sticks, its a DANA 20. If it doesn't wipe it off better to be sure, and try again, if it still doesn't stick to it, then it's a DANA 300, and someone swapped it in some moons ago.

            The tailshaft of the DANA 300 is aluminum, and it's achilles heel.

              You mention oil?

              I have had great improvements in synthetic gear oils for many applications. Always a noticeable noise reduction and if you paying attention easier shifting and cooler temps.

              Redline recommends their MT-90 for our IH transfer cases and transmissions.

                  if its original and a 2 sp, its a D20. its ok to run it at highway speeds but i would running it in 2wd whenever its not really necessary. might be better to keep the hubs locked and just engage the t-case when you need it if getting out and turning them everytime is a hassle. id rather have to replace worn out hubs than a transfer case if it comes to that. my 73 scout had a D20 and 3.73s and i wouldnt want to drive it over about 60 anyway.

                  as for yellowdogs transfer case unless someone swapped it, it should have the New process 202 like my 69 1200 has. they used 202s until around 70-71. apparently just about identicle to the 205 mechanically and at least as strong but has a different shift pattern and i think the gears are straight cut in both ranges, not just low as in the 205(?). if 2wd position is all the way forward then its the 202. mine wines in 4wd and howls with the hubs locked.

                  carl by the way, i have those fenders for you. -ryan

                    Thanks for getting the fenders. I don't have long distance anymore and I was just trying to figure out how I was going to contact you. Write me [email protected]

                    I guess I have a 202 in the 'Dawg Thanks
