log truck

treefarmer87 · February 16, 2012, 12:03:55 PM

well 2 days ago i was taking 2 cars to the junkyard for my stepson and on the way threw a rod through the oil pan so i have been looking for a truck

As they say, no good deed goes unpunished :-\. Sorry to hear about it, does it have a 466 diesel? They are an easy engine to rebuild and also a very common one if you would need to find a used replacement for it. Once again, sorry to hear of the bad luck.

treefarmer87 · February 16, 2012, 03:02:44 PM

your right sandhills. It had the 6.9 in it. I found a good deal on a cab and chassis intl. 1854 dt 466, hyd. Brakes, 5 speed 2 speed rear. It was rebuilt at 100,000 mi. All it needs is tail lights.

agree on the DT, good tough lil engine

snowstorm · February 16, 2012, 04:43:26 PM

air breaks are a must have. at least a 12k front 21 rear double frame. then if you ever want to put a tag axle under it you can

treefarmer87 · February 16, 2012, 06:34:43 PM

I know what you mean snowstorm. i have always wanted a tag axle under one of my trucks

Bobus2003 · February 16, 2012, 07:27:31 PM

You have a 420ci 6.9l.. Very easy to rebuild, and can be done for about $600 bucks (re-reing) and 1200 Master kit if you do it yourself.. I have done a few. You could also look for a 444ci 7.3l IDI and swap it in.. Almost identical engines just has more Horsepower, All electrical components are the same, Can be found either N/A or Turbo'd and are easy to find and pretty cheap too

treefarmer87 · February 16, 2012, 08:24:33 PM

Bobus i like the sound of putting a 7.3 in it 8). a friend of mine has a chevy with a 366 with a new rebuild. 5x2 rear for $1200. i think i am going to pick that up tomm. and get another motor or rebuild mine, so i can have a back up

sandhills · February 17, 2012, 12:48:49 AM

I have a 6.9 parts engine if you need a rod or 2, don't know for sure how they're machined though, I know it was a factory reman when I bought the pickup. If it can be of any help let me know, the price would be right ;).

Ohio_Bill · February 17, 2012, 07:27:53 AM

Treefarmer, Sorry to here about your truck engine. Those things happen with new and old equipment alike. Sure sounds like it would be worth putting an engine in it. Would the expense of 2 sets of tags be a big deal, or are they not that expensive?

chevytaHOE5674 · February 17, 2012, 08:46:06 AM

Personally I would stick with a 6.9 over the 7.3. The 7.3 is a 6.9 block that is punched out so it has thinner cylinder walls. With a 7.3 IDI you have to really keep an eye on the nitrate levels in the coolant or else they can develop "block worm" between the coolant passages and the thin cylinder walls.

snowstorm · February 17, 2012, 04:24:11 PM

if you are going to pull that 6.9 toss it and put a dt466 in it then youll have something. as far as the blocks pitting on the 7.3 any diesel will do that if you dont have a water filter or use the treatment

treefarmer87 · February 17, 2012, 05:10:58 PM

snowstorm you have the right idea, dt 466 IS the way to go i test drove a log truck with that in it and i really liked it.

True any diesel will do it just that the 7.3IDI is well known for it. The 6.9 just has quite a bit more meat so if the nitrate levels in the coolant aren't maintained perfectly they will still last many many years. More than just "using treatment" they make test strips to test the SCA levels and then you add different things based on what the test strips return with. Putting additives in the coolant without first testing for what it needs can be as bad or worse than no additives/testing.

you can make this as complex as you want. a water filter is the best way thats why all big trucks have them. as far as the 7.3 being known for it so was a cummins. do you know why it pitts thu?????? i do i wanta here your answer. a 6.9 or 7.3 is a light mid range engine. ok in a pickup still underpowered. i have a 93 7.3....now retired.... its all of 180hp. the dt is a far better choice

treefarmer87 · February 17, 2012, 07:37:00 PM

a DT 466 is 210 HP i think ???

ya it may be if its an old one. the d means direct injection t means turbocharged later ones are intercooled then the e computer motor. if you ever swap motors put a pull clutch in it . the baby motor most likley has a push. pull is much better 2 plate with a clutch break

chevytaHOE5674 · February 17, 2012, 08:33:53 PM

I will agree the 7.3 and 6.9 are motors built for pickups. I have a turbo'd 6.9 at the moment and while it is not a fancy powerstroke or cummins it can surely holds its own, and it is super easy and cheap to repair. And they are common as can be around here (can get a junkyard running 6.9 for 150 bucks).

And snowstorm as I understand it cavitation is the high pressure in the diesel motor causes vibrations which cause low pressure areas to form along the irregular cylinder walls. When that pressure drops below vapor pressure point this causes a vapor bubble to form and then burst. This repeated bursting "eats" through the cylinder wall.

snowstorm · February 17, 2012, 08:39:09 PM

they implode inward. a turbo 6.9??? old gale banks kit? goggled the answer didnt ya?

chevytaHOE5674 · February 17, 2012, 08:53:40 PM

No I've owned diesels for many many years in trucks and all kinds of equipment (currently have 10 diesels). And owned 6.9 and 7.3 IDI's since I can remember. Done plenty of research and reading on them over the years as I like to tinker and mod them.

Now I have a 6.9 with an ATS 093 wastegated turbo on it. I had a 7.3 with the old style banks kit on it but didn't like how the turbo spooled up too high in the RPM's without the wastegate. I hear the newer banks sidewinder is much better though. Would like to try a banks sidewinder and a hypermax setup on a 6.9 IDI someday.

I have a '86 6.9l, thats been bored .20 over, Has the '94 IDI Turbo Diesel Injector Pump and Injectors, Pistons, Has the IP turned up 3 flats, Running a Banks Sidewinder Turbo and a few other things, she Dyno'd at 300hp

Have a '93 7.3l w/250k miles that i have never done anything with the antifreeze and no issues, Dad had a '83 F250 with the 6.9l that had almost a million miles and never did anything with the antifreeze.. Many head gaskets though..that's a 6.9l problem (Almost always the pass side).. It's actually pretty hit or miss.. just like the Cummins 53 Block crack issues.. not every one of them suffers from the problem

And the 6.9l was used in Combines long before it ever made its 1983 debut in Ford Trucks

chevytaHOE5674 · February 18, 2012, 09:20:29 AM

You've been lucky. I have a 93 7.3IDI block in the garage with a hole through a cylinder wall. Odometer showed less than 200k miles. I'm guessing the previous owner used lots of tap water in the coolant over the years.

My current 6.9 has ARP head studs and I haven't had a head gasket problem yet. "knock on wood" haha

treefarmer87 · February 19, 2012, 08:40:37 PM

looked at the truck today it is a good buy. It has a rebuilt 427, 50,000 mi. 5 speed with 2 speed rear and pto. I might end up putting a prentice g behind the cab also.

snowstorm · February 19, 2012, 08:56:13 PM

427 wasnt to bad for a gas motor. the bad part is its a gas motor. a lot of them that had loaders on them up way broke the frame in them. not many 6 wheel trucks around here hauling wood.
