Removing the High Side of a 241 or 208

[4bynut]

Does anyone have any experiance or maybe know of a good right up on removing the high side from a 241 or 208 t-case? A buddy said he's heard of doing this to reduce weight with our mud trucks. We just run low range anyway. So i'm curious what you take out and what you weld. Also if you have to add anything. Thanks for any help.

I don't really think it's possible (or a good idea) to remove the high range in a t-case. Since the high is 1:1...and the input/output is a straight shot through the case. It may be possible to remove low (don't think that's a good idea either).

There have to be easier ways to remove weight from your rig. It might not be rotating weight though.

If you really want to remove some weight, have you considered a chain drive set up?

i know they just did it on extreme4x4 but i can't find it on thier site. We are just running in a straight line pit so it should be alright. And we are running classes that it's not allowed to run a chain drive setup. It has to be a production type t-case. We always run low range because it seems to work better and we can use stock gears more.

Thanks

Well, both 208's and 241's use planetary gearsets. No way to remove any part of the reduction part of the case and still have a low range (i.e. what you're asking is impossible).

Beside which, you'd drop what, 10 lbs?

If you're wheeling a fullsize, you have about a thousand other places to look for weight loss before the 75 lb. t-case.

Low range comes from the planetary gearset. In theory you could remove the gearset and have only high range, but not the other way around. If you wanted low-range only, you could probably lock it in with a collar or spacers to save the weight of the shift forks, shift rail and linkage, but that can't be more than a couple of pounds. There is some advantage to it not "popping out" of gear, but as for weight reduction, your effort would be better spent dieting.

no doubt. You would loose more weight pulling out a rear window then doing whatever they did to eliminate 4 hi. Remeber those Extreme experts are the ones that said they saved more money buying full on custom pro rock dana 60's rather than rebuild junk yard axles.

If you are talking about removing the high range from the t-case.......well, there is nothing to remove that would still make the t-case function. The output of the trans attaches to the input of the t-case, in high range it is basically a straight shot to the rear output, with a chain and sprocket on that shaft that turns the front output. Put it in low range and you engage the planetary gears at the front of the t-case, which then goes through the above mentioned shaft.

I'm not sure on exactly what you are referring to in regards to the Extreme4x4, but my guess they were doing some sort of doubler where they just use the planetaries (low range) part of the t-case. However you lose the "4wd" part of the case to (cuts off the front output).

I could be wrong but, I'm pretty sure they eliminated 2wd high and 4wd low on the Xtreme 4x4 episode? They figured with the right gearing all they would need is high range 4wd (1:1 and good tire speed). That might would be pretty easy (depending on the case). Ruins the transfer case for any other purpose other than mud racing though. As said previously, I'd look elsewhere for weight savings rather than spending time and money ruining a transfercase to save maybe 10lbs!

Thanks everyone for the insight. I'll forget this idea, it don't sound like it's worth anything to me. I need low range and saving ten pounds isn't worth enough.

Thanks again

NP203, NP208, and NP241 are all a chain driven case.

LOL! I meant we have to run production t-cases. No custom chain and sprocket setups like the open class uses.

The wording leaves a bit to be desired. Sounded like you had to run a gear case and not a chain case.

Ya, maybe i should have been a little clearer. I'm running a BBC, TH400, and drivers drop 241 to use with my furd HP D60 front. It's all going in the 70 blazer in my avaitar.
