what is the reasonabe expectations one should expect from a first gen
after 250000 miles what will be worn out
axles ,transfer case [4x4], getrag trans ,non intercooled cumins
i realize every truck is diff but at what area of miles shoud a buyer get scared off because the useful life is about gone,
thanks,

 

So long as you get a rebuildable engine, no amount of miles is too many; because when all of the good trucks are given up on, then all we will have left is the electronic junk that the computer freaks insist on shoving down our throats. They aren't making any more mechanical engines; and they have had time to get a bunch of miles on them since their production.

 

what your asking for can't really be given, it all depends on how well the truck was taken care of, and parts just seem to fail at differant times . my 1990 has given me very few problems with almost 400k on it. this week I lost the orig, injection pump at 300K i lost the rear diff. stock auto is still holding on but barely, its a leaky mess. the trucks have lots of servicable parts . i just had it repainted, new window rubber, door hinge pins,starter. alt fan motor,etc.just small parts and still its a solid truck. the parts i spend $ on are still less than a truck payment. but this year it looks like i will need to infuse a big chunk o cash in her. (trans. IP, injectors, and a few small items) the engine ran as good as new before the IP took a dump. for me i will keep it running as long as the body and frame hold together... then I will find another first gen to drive.

 

410 on clock and running like new. i change tranny oil every 6 months and diff oils every 6 months transfer case with the rest iof them. not afraid to go to ca right now either.

 

Mine has 240k on it and I'd drive it anywhere.

 

I bought my '89 last Fall with 180k miles. It looks like the trans was redone recently. To clean to be original. It has a 5 digit odometer so I have to take the original owners word for the milage. No leaks and I would take it anywhere. I plan to drive this one forever. I just wish it would cruse over 70.

 

A 3200 RPM governor spring will do that for you.

 

Mine has 253,000 and its off on a more than 400 mile round trip with a trailer taking a truck to my uncles in NY state.

 

If I were buying it, I would take it home, drain all the oils. Pull the dana 70 cover and check/adjust the backlash on the ring and pinon. I would pull the pto covers off the getrag, pry the shafts back and forth trying to find any endplay. If there is any, I'd reshim it. If the shafts were tight, and there wasn't anything in the oil besides brass, I'd fill it up, overfill it and forget about it for a 6 months to a year.

Mine has 225,000 miles on it, the only thing I'd do before hooking to my gooseneck and heading to California, is check all the oils, rebalance the front tires, and fill up on diesel fuel.

About 260K on Stinky, the non-maintenance items parts list includes an alternator (brushes worn out), a turbo, motor and trans mounts, springs and shocks (front springs were tired, rode more on the bumpstops than the springs), a lift pump and bearings in the A/C clutch. Of course, these trucks last so long I guess most any part could be considered a maintence item.

 

Ya got to quit worrying about those "baby" mile trucks. My 93's got 1,124,000 miles on it. Yep, I did all that. It still looks good and runs great!!! Only exception is the occasional hiccup in the wiring dept.

 

Wow! Any internal engine work needed?

 

Boomer , what do you do with your truck? You must tow some , I did the math on that , and for the sake of argument i assumed it was bought in 92, That is 1672 miles per week for 14 years..., 6690 miles a month , or 80 285 miles per year.

Assuming it was on the road 5 days a week , that's 334 miles per day, It is very possible , and very cool to have that many miles on it. I'm just curious what you do with it to put that many miles on...

 

When I am hauling cattle, it is easy to put 100,000 a year on the truck.

It is not unusual to be on a trip that over-runs a couple oil changes.

 

Is there really such thing as too many miles? We simply revive things that die around here, I like the old trucks better than the new ones with a payment
