Transfer case. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*racedvl* · 06-30-2002, 11:07 PM

I'm going to go look at a 1980 K5 tomorrow. It has a 350- 4 speed manual. What transfer case would this truck have? And is it a good one?

BLAZERMAN · 06-30-2002, 11:12 PM

It wil have an np-205 case, very strong gear drive case.

*racedvl* · 07-01-2002, 08:03 AM

Sweet!

It is rusty from what the guy says, but is supposed to run real good. It comes with a plow. The guy wants $500 for it. As long as the body is not falling off the frame, I might make it my new daily driver.

**68SWB4x4** · 07-01-2002, 12:53 PM

sounds like a perfect trail rig to me!

*racedvl* · 07-01-2002, 11:14 PM

It was a good trail rig. And that's about it. She was REAL rough. Is a 4.1L a 292? That's what it was supposed to have.

**MJN** · 07-02-2002, 12:00 AM

If it is an '80 it might have full time 4x4 (no lockouts) if it does then you will have a NP203 chain drive case not bad but weaker than gears of course. Have you checked the engine? a 4.3 v-6 is a 262 ci so a 4.1 might be a 250ci.

MADRAD · 07-03-2002, 09:43 PM

Look,
Your dreaming to think that a K-5 that was made in the 80's has a NP205 as standard equipment. More than likely the truck will have a chity NP208. Chevy mixed 203 and 205 in the 73 and up blazers. In the late 70's and early 80's they install NP208 as standard equipment. Chevy still use the 205 in there 3/4 and 1 ton truck until they made the big mistake with that crap IFS system. Why in the hell would some engineer wanted to make a truck act and drive like a car is beyond me. People can spend all the money they have and still cannot get the proformance and strength that a straight axle can give
Now there nothing to say if the current owner decided to install a 205 in the K-5. You just don't know with used vehicle these days. Also, if the owner doesn't have a clue what he has in the truck. I'm pretty sure it just has what it came from the factory.
Please take the time and effort to do some reseach. Learn what about the goodies you and how to ID them. Learn to trouble shoot a vehicle promblems before you end up spending more than you wanted for the thing. Just because its a good buy, doesn't mean that the seller has your best interest in mind. Hell, try to get it for less?? Hope this help.. Rock on people!!!

**JIMs70GMC** · 07-04-2002, 08:50 PM

Here's what I found:

dana20 69-73 blazers w/ manual and 6 cyl.
NP203 73-79 all K series with auto
NP205 69-73 blazer w/ auto, trucks 67-79 w/ manual, 1980 all, 81-88 1 tons

NP208 81-88 all 1/2 and most 3/4 tons.

nu2-72 · 07-07-2002, 12:58 AM

Well, I do believe he asked about a 1980. Any more comments ?

Blazer1970 · 07-11-2002, 07:18 AM

ALL 1980 GM 4WD trucks came with NP205s. 1979 was the last year for the NP203, and the NP208 started in 1981. It will have a slip yoke rear output though. 1980 was also the last year for 12 bolt rears.

It is always interesting to see someone like MADRAD post incorrect information with such authority.

Milenko72276 · 07-11-2002, 09:39 PM

Yep,Blazer knows what he's talking about.All GM 4wds in 1980 came factory with an np205.

chevytruck68 · 07-30-2002, 10:28 PM

the 4.1 litre is a 250 the 292 is a 4.8 or 4.9 cant remember

**68SWB4x4** · 07-30-2002, 11:55 PM

**JIMs70GMC** · 07-31-2002, 05:37 AM

Palallin, You got me I meant to change that rockwells were from 67-69.

palallin · 07-31-2002, 02:04 PM

Phew! I thought I was gonin' nuts.

BTW, where those Rockwells put in anything else?

chevytruck68 · 08-01-2002, 12:55 AM

As soon as my replacement arrives and is installed, I will have most of my old one. I say "most" because I know for a fact that some of it will be unuseable (hence the replacement). What do you need?

chevytruck68 · 08-01-2002, 10:48 PM

this is a pic of the power take off on the back side of the case i need the cover that fits over it and the bearing at least i thnik there was a bearing

Remind me next week: I may have the old t-case at that point.

diehardrider · 08-02-2002, 12:52 PM

do you use the PTO for anything?

jeff69cst/10 · 08-02-2002, 11:15 PM

You cann't always trust what you read!
My 79 was built in the later part of the production run and is built with parts combos from the 80 model year(found this out trying to buy parts from a local dealer)!
My drive train option was not avalible in 79 but it was in 80 (again according to the dealer)but is a 79 model k20.
The truck was all original with matching #'s when I bought it from the original old farmer owner.

Just trying to say you cann't always trust what you read!

no i dont use the pto last year i was on my way home from work and heard a weird noise and then a loud bang i stopped and found the cover laying on the ground in pieces and what looked like pieces of a destroyed bearing i havent driven the truck since so i wouldnt totally ruin the transfer case

**chevy71super** · 08-03-2002, 11:29 PM

My 1979 K10 came with full time, chain driven transfer case. It was a 350/350 auto. I converted it to part time using one of those kits. The transfer case lasted about two years after that when the bearings went bad. Swapped it for a 205. I wish I would have not let that truck get away . . .
