HD Transfer Case

[hammersley]

Ok Ok - what the heck difference is there in the 214 transfer case and the 241 HD? Why would DC make a Non-HD version - I mean who would really want that if they had a choice? Unless the only difference is maybe shift linkage or something associated with the actually snowplow operation where one may shift in and out a lot?????? By the way - what is the exact WWW address for teh Fritz Page?

Fritz's site is at http://dodgeram.org/



Note, there is no www in the address.



I think one of the differences in the HD xfer case is that it has a PTO. It can also handle more torque. Why Dodge ... can't answer that one.

Fritz Page Great

I don't know how I missed this page before - great - here's the info directly from their page - on Transfer Cases... . stuff on the Transfer Cases:





Transfer case versions: NV231, NV231HD, NV241, NV241D, NV241HD



The NV231 transfer case is used behind many V6 and V8 engines in pickups and sport utility vehicles.



The NV231HD, used in the 1994+ Ram with V6 and V8 engines, features larger bearings and a wider chain than the NV231.

All versions of the 231 cases use three gears in the planetary reduction set.



The NV241 is essentially a NV231HD with six gears in the planetary set.



The NV241D is a heavier duty Dodge version of the 241, with a larger input shaft and larger bearings to withstand the torque

of the V10 and diesel engines.



The NV241HD, an option on Ram 2500's and standard on Ram 3500's built after 1998, has a stronger case and wider drive

chain to better withstand the shock of snow plow service, a PTO cover and drive gear, and an extra bearing to support the

thrust to the main shaft created by a PTO adapter.



Except for dimensional differences and the PTO port on the NV241HD, all of the cases are almost identical in appearance. An

identification tag is attached to the rear case of every transfer case. The tag provides the transfer case model number, assembly

number, serial number, and low range ratio. The transfer case serial number also provides the date of build. For example, a

serial number of 9-10-93 would represent September 10, 1993.
