besides dually rear ends what is the difference in trucks? ive owned a 3/4 ton but never a 1 ton and i might buy this 91 single axle 1 ton. is it just a heavier leaf pack in the rear? thanks!

 

[gary j westrope]

yea pretty much i think thats the only difference just heavier leaf packs or stiffer coils in the front on 2wd...

The GVWR on the 250 is 8510 and the 350 SRW is 8700 so not that much difference. The 350 dually is 10,000.

1 ton had clearance lights on the cab on duallies. (Not on 1 ton single wheel)
Front and rear axles are supposed to be different with the 1 ton axles rated for more load. Springs and shocks are differant #s. (There are 7 spring choices for 1990 alone)
If it is a dually, the hubs front and rear are changed from the 3/4 ton.
i'm pretty sure the steering gear is the same, the brakes are different.

I had a single rear wheel 1 ton before I got my 3/4 ton.

Remove the oil filler cap when the engine is running to check for any blow-by. If clear and the auto trans shifts smooth with no slip then it should be okay if the price is reasonable. These engines are pretty tough if well maintained.

I looked at one a while back that was smoking like a chimney out the oil filler neck and I told them 'no thanks'. They were telling me 'they all do that' but there should not be any blow-by getting past the rings if the oil was changed on time.

I've seen lots of diesels do that and they all have ra a long time. Most will have some blow by, but if it looks like your exhaust when you stand on it, thats bad!
I wouldn't say no just because of blow by, but if it had other "issues" then it would be a turnoff.

yeah they will all have some

I asked the dealer what the difference was between 3/4T and 1T. He said mostly brakes. Has heavier brakes to stop a heavier load.

This one was pretty bad IMO. It only had 170,000 miles. I have seen cummins with much higher miles with no noticeable blow-by.

There are lots of these trucks out there if you look on e-bay or autotrader. Why not get one with less wear on the engine?

You are right, though. The engine is going to run fine even with blow-by. Not a reason to get rid of a truck.

i went and drove the truck last night. it runs well but i forgot to check for blow by, i was tired. got there at 8pm and had worked from 5am to 4pm that day with lack of sleep the night before!

anyways its a non intercooled 91 1 ton with e-range pirreli scorpion A/t tires. yeah the brakes do look bigger. the current owner got it from the original owner and he put isspro gauges, fuel pin, pump turned up. it already had a straight pipe. its got dual battery set up. he put h4 lights which work GREAT! it pulled 17-18psi of boost when i floored it, trans feels just like my other cummins (good). needs the kingpins rebuild but it doesnt hop. its a LE too. i think im going to buy this one. i found a 90 with about 160k but she wants more then is in my budget and she wont come down.
