For those that question the strength of a 241 t case

ngoluba said:
I have no opinion on the 241 either way, but I'm not sure this was such an impressive test of a transfer case.

What I see is a TBI SBC (not a real powerful motor) spinning tires on a very light vehicle. The TH400 also absorbs and cushions the power fed to the 241 in ways dumping a clutch does not. The stress I see is the lockers and the 42's, but that's partially mitigated by the 5.38 ratios.

I would be more impressed by a big block Suburban rolling on 42s loaded down with 50 sheets of drywall trying to get up that hill. Not that something like that would happen, but you get the point.

BTW, this guy seems a little rough on tires. If you noticed, he didn't make a lot of progress when the tires were spinning and he rocked side to side hunting for traction. Yes, hot tires will give you a little better grip, but he made progress when he backed up a little and used momentum and finesse to bump up and over the ledges. Pinning the pedal on the right and spinning the tires for 10 to 20 seconds at a time on rock might win points with the spectators, but it usually isn't the ticket to the top of the hill.

Perhaps this was a competition and he was trying to avoid deductions for popping it in reverse, or stopping. Tire spin has its place in mud to clean the tread, but on rock, a spinning tire is a tire that is providing less traction than is available.

While I'm not sure this was a good test of a t-case, it was entertaining!

Edit: Maybe that motor isn't as gutless as I assumed. I re-read the specs and it's a Howell TBI, not factory. He could have decent heads and a cam and used the Howell to tune it.

Replying to the bold sections:

First off. The 350 TBI engine is the most powerful SBC ever put in a truck since 1973. Including the SB 400.

Second. Howell TBI is stock GM throttle body injection. Uses all stock GM parts.
 
Alright then what is a 261 case :dunno. I swear when i looked under my friends truck (he asked me what he had) the tag read 261. :confused:

Also i think that video shows alot of what they can handle. Hell it impressed me :D

261 are floor shift cases that came in 99+ 1/2tons, they are slip yoke front and rear output

That does not say much or provide an accurate reading of why a 50 year old axle shaft broke..

Axle shaft could easily have been worked hard while it was under a 14000.00 pound truck being driven by who knows. Its also upstream from a 6.71 gear set.

the 241 is not that much lighter than a 205, within 20 lbs of one another.

Actually, IIRC the 241 is 80 lbs and the 205 is like 155 lbs.

I have to agree here with the comments on the trail. Then entire time I'm wondering where the tire spinning is getting him. While I know toasting the tires can evaporate some of the moisture on the rocks under those situations and heat the tires, wouldnt it be more worth it to crawl it out and bump up the ledges like he winds up doing anyway?

I have shipped 2 of these they were 130-135 pounds dry, depending on if the shifter was there or not. Wet they should come in around 135 pounds.

208 should hit right about 75-80 lbs not the 241

edit... 241 is not 115 pounds

The 208 and 241 are almost identical weight. :deal:

hmmmmmm


Could have swore my slip said 115 pounds when I had to replace the one in the burb, and thats before they crated it. Now this is killing my brain rather than concentrating on work:doah:

the 205 I am certain on.

anyone know the weights of the 243 autotrack?
