Hi,

in doing a little research I came across an old IH b-160 brochure on ebay that says the transfer case used in a b-160 is a 3-speed unit. This, to me, then sounds like the ultimate truck transfer case upgrade. Who makes it? What model is it? What ratios does it have? Overdrive 3rd? Can anyone please give me a little more information on it please. Thank you.

this is the info copied from the brochure:

transfer case: declutching type. Three position shifting - high, direct, low, 2.25 to 1 reduction; neutral. Manual engage and disengage of front-wheel drive. Provision for mounting full torque power take-off at rear of input shaft.
 
Update: the ebay picture was not very clear and the punctuation was not clear.
What looked like this on ebay: three position shifting - high, direct, low,
is actually this: three position shifting - high, direct; low,
and I now assume to mean this: three position shifting - direct, neutral, low,

here's the complete IH pdf brochure with those words exactly:

Sorry if I jumped in and posted before researching, I just get excited every time I think I learn something new about these trucks. And when I read that brochure on ebay, it was shortly before I had to leave for work so I just asked without researching first.

In cts 2000 which covers 57-63 a b c models, I see in the transfer case section a reference to tc 152/code 13152 and tc 153/13153, which are two-speed cases with two shifting levers and a low range reduction ratio of 2.25 to 1. One lever is for selecting between direct drive or low range and the other is for engaging or disengaging the front axle...similar in that regard to a Dana 18 in a Scout 80, or a Dana 20 that has been twin-stick modified. I think that May be the source of your confusion. These are divorced or frame mounted cases and they look damn heavy!
 
Hi and thanks for the reply.

I apologize for my ignorance in regards to IH trucks, but I'm learning. What is a cts-2000 and where can I read it? What does cts stand for?

My truck uses a divorced transfer case. Just wondering if there are any companies that make different gear sets for a 205? I'm thinking with a klune attached to the front and an overdrive rather than under drive set of gears in the transfer case, I would then achieve what I'm looking for - high-speed for 65+ mph on the freeway, direct for city driving, and under drive for off-road. Any thoughts on this possibility? Any off-the-shelf aftermarket anything that will help me achieve this 3-speed goal?

Just thinking outside the box. ;-)

I had a b-160 dump truck 2x4 with a 2 speed rear axle. Perhaps if you could find a 2 speed axle for yours with the low range on the axle matching the gear ratio of your front axle, you could use the high range for greater top speed on the freeway. However I don't think a bd264 will move the truck that fast. How does it climb the hills in top gear now?
 
I don't know what cts stands for, but those letters followed by four digits (2xxx) are how the IH light line service manuals are identified and arranged according to vehicle platform and model year(s). The vendor who owns this forum, IHPA can provide a reprint of the fsm that pertains to your year and model of truck, but you would need to provide that specific information in order to get the correct book.

The new process (np) 205 case you have is extremely common since every domestic auto maker has installed them in their full size 4x4 offerings over the years. I imagine the webs would be your oyster as far as researching goes. If your idea is feasible, someone out there has found a way to accomplish it. Maybe even more than one way. Just be sure you take into consideration what your return on any investment would be. How much are you willing to spend to reduce your 65-70 engine speed by 500 rpms while still being able to snail crawl off road when you need to? What's your anticipated ratio of pavement versus off-road driving? What's the motivation behind all this? Cool factor? The hope/quest for better fuel efficiency? Can't hear the radio because your cornbinder engine runs too fast at freeway speed?
 
" cts " I think it stands for ( check truck service ) manual 2000 ? Or ( code truck service ) can't find it in the parts or service manual. I've gotta cts-2001 manual,if you need any info...Jeff
 
Sounds like a brownie over/under box I had in our farm truck years ago. It's considered an auxilliary trans
