Pulling tractor with a deuce engine

[JasonS]

Do the road and farm tractor engines use the same rods.....

The farm tractor does not. I'll try to find the link discussing this...

Excerpted from Oliver, Cletrac, Co-op & Cockshutt Tractors Discussion Board - Re: 2-155 cummins conversion I have NO idea if it is accurate.

There are some differences in the 478 used in the Army trucks and the ones used in the tractors. The blocks are the same casting but the tractor engines have a few more holes drilled and tapped in them for the water pump. The heads are also the same casting but the two are machined a little different between the valves. The truck engines have a multifuel injection pump so the pump and plate behind the timing cover and the timing cover is different. Also the timing gears are different on the truck engines and the tractor with the roosamaster pump. Some of the army truck crankshafts are also different. they have two more counterweights on the crank and they are much larger. The rods in the truck engines are also lighter. The intake, exhaust and water manifolds are also different. The oil pump and oil pan is also different because the large sump on some of the army trucks is in the front instead of the rear. I believe the 2 1/2 ton trucks have the sump in the front and the 5 ton trucks have it in the rear. The tractors have it in the rear. The army truck engine can be made to work in the tractors. It just takes a little work. These army truck engines can be Hercules, White or even Continental. They are all the same casting. The truck engines are usually an LD-465 or an LDT-465 or an LDS-465. The 465 is not the cubic inches they are still 478 cu. in. just like the tractor engines.

@ booger , yeah. If you have the rods out , you magnaflux , and resize.... But if your just dropping your pan , its a different story.

And so many guys keep saying "Turn 'em up and blow 'em up!!" which has not been my experience with our trucks. These engines in farm and pulling tractors prove the opposite of that mantra.

Go to youtube and search ” Oliver 2150 tractor pull steel city pull” hes running a Hercules 478...

It turns out that there are two different TD military blocks. The LD and early LDT blocks that I have are squared off around #6 while the later LDT are rounded on the passenger side with two ribs extending vertically on each side of the frost plug at the rear of the block. The tractor pulling crowd has noted a problem with #6; wonder if the ribs were added to correct a known problem? I'll add pics tomorrow....

I will add that it's a big difference building a high hp engine to pull a sled 300' down the track and building a engine to hold up for road use. Even though the tractor engine is turning high hp and high rpms pulling a massive load, I bet it wouldn't hold up 100 miles down the road at those numbers.

If you'll notice on pulls some people won't even run their tractors to hook up to the sled. They pull it into position with another tractor and won't start the puller until it's time to pull. They will then shut it down at the end of the pull and have it towed off the track.

brings to mind a old saying , the olny thin faster than a fast motor is green dollars, in this economy its wise to keep your dollars, providing of course your motor allready runs.

I, for one, have no intention of cranking 4000rpm or turning the fuel up to 300+hp.

But, examining what fails when you do seems a great way to find and address failure modes.

Pics attached but don't show the rounded block on the later TD block.

JasonS,

The 25 USD pr bolt was for 500-1000 units or less. So the more people that can get behind this the better.

Holy thread resurrection Batman!
Glad you bumped it though, now I saved it.

So are these rod bolts from Tractorjoe a high quality replacement for the stock LDT or LDS Duece engine?

 

[Jeepsinker]

Yes they are. Better than stock anyway.

 

[mark salanco]

Has anybody on this forum used these rod bolts from Tractorjoe ??

 

[w3azel]

Be careful when purchasing these parts. I would even say call before you order and check on the size of the bolt. I purchased an injector for an Oliver 2150 Hercules and it does not look anything like the stock ones.

Did the injector fit the engine?

I wonder if they sent the wrong part. The pics in this thread sure look like should have the same injectors: http://www.steelsoldiers.com/showthread.php?73830-Oliver-2150-with-multifuel
