I read this on a M715 site :
I was wanting to know about the NP 202. I have also been looking for a 202 to finish up the upgrade on my driveline. However, my book (and everyone I talk to) doesn't have the low range ratio or torque tolerance. Can you tell me what yours is? Also, I think that they came out of a 2.5 ton International. What kind?
Anyone know what the spline count is for the output shaft of the NP200 transfer case? I have not pulled my yoke off yet and am still looking for a flanged yoke that would possibly bolt to the brake drum when I change the driveline to the brake location.
The NP 202 is a through drive transfer case that is dimensionally about the same size as the NP 200. Most people prefer the NP205 to the NP200 as the 205 is also a through drive design but the NP 202 input and output shafts are a good 1/4 inch larger in diameter and the gears measure a good 3/8 thicker and the front output shaft rear bearing cap is iron instead of aluminum. They used these transfers in 1 ton and 1 1/2 ton and 2 ton and maybe possibly 2.5 ton IH trucks but I am not for sure on that one. The transfer has the same lowrange as the NP205 and NP200 but it also has a neutral position so you can use the PTO outlet on the 202 and speed up and reverse your winch with your transmission. Internally this transfer makes the 205 and 200 look puney.
The NP202 is basicaly a larger and heavier duty version of the NP 205 as the operation of them is the same but the shafts and gears in the 202 are larger and require a custom 1350 forged steel spicer yoke{$95.00 apiece) if you want to convert from 1310 U-Joints
Start looking at International Harvester trucks, they are the only ones I've ran across that have these monster cases. mostly in ex-power company type trucks 1 1/2 ton and up. usually these large IH parts are cheaper (I've found) because there is hardly any market for them. (good for us!)If you part one out, you should be able to get the old driveshaft and its' expensive yoke too.
I do not know what a fair price for a 202 would be (Pascal said he gave $200 for it at pick a part). Some of the extreme duty IH trucks came with the Dana 70 with 35 spline inner and outer axle shafts (good luck finding a lockout hub with the 715 bolt pattern and 35 spline) Some of the IH trucks came with the same axle as a 715 in the front, Dana 60 with 70 knuckles and spindle and hubs but use the 30 spline shafts and as commonly believed these are not the same as Dana 44 shafts as they use an enourmous U-joint and are a vey strong forging and unlike a Dana 44 do not have the recessed area just before the seal(where they always break) or the miniature 44 outer U-joint breaks and destroys the entire shaft. Truthfully though out of simplicity I would probably use a divorced 205 as it is plenty strong and you can modify your stock transfer brackets to work plus if you want to change the yokes and U-joints to 1350 spicer the yokes are cheaper.(the 1350 yokes for a 202 cost me nearly $100 apiece as they are forged steel instead of cast and they were not available from spicer in cast.
