Brought my new to me truck home today, on my birthday.

Needs a little bit of TLC but I have 5 months before I'm putting it to work!

Nice looking truck! I'm assuming you passed on the kW you were looking at last year? Does this mean your current puller is going to be retired?
 
Couldn't come to an agreement on price on the KW I looked at in October. I just didn't have enough cash. But that's ok.

My dad found this truck about 4 years ago. A good friend of ours was looking into start trucking and he bought this truck to get started. About 2 months ago he bought a newer truck an knew this one wouldn't get the attention it deserved. He knew that I was looking and decided to sell it to me. I've wanted this truck since my dad first go pictures.

I'll still be pulling my A model. It's just going to be more of a "restoration" project rather than a power house.

Bingo! See the issue with the Acert IS NOT THE TURBOS! However guys owned earlier C15/3406E's and had great power and luck. Then they got an Acert and some issues. So they raise the hood and the ONLY difference they can physically see is the chargers so they insist on spending a pile of cash to remove them. Then they almost always realize that was a mistake. They paid money to get a narrower power band and lose performance.

The only good things about removing them is it makes a few repairs easier. It also keeps idiotic steering wheel holders from lugging the motor down to 1100rpm, because unlike a single the factory chargers will still make power there.

But since some guys insist removing the turbos will "gain them 2mpg" because they read it on the internet...... We have lots of parts available to guys that want usable 800hp to the ground.

only because idiots were selling them wrong type of singles.

Whats wrong with lugging down to 1100 rpm, or even 1000 ? Those engines were designed so.
 
Compounds will give you more usable power than any single could ever dream of

Let me guess Lenny, Europe has the worlds greatest turbo configurations on the planet! And some guy you know who knows another guy who knows another guy has a custom made single that will support from 25hp to 2500hp with ZERO smoke and instant spool up on some obscure antique L10 that you have nothing to do with.

The point is these guys spend thousands of dollars for nothing! You only have so many configurations of stock parts to work with. "Custom" has no place in the work truck market. You bolt a weird charger on that you can't get anywhere your asking for trouble. Keep in mind, this is the USA. We have states that are larger than your entire country. No one wants to be broke down 3000mi away from the nearest available replacement part.

Why don't you want to lug it down to 1100???? The same reason you don't drag an engine down on an engine dyno. Some guys don't want to piss pound the hell out of their bearings or put unnecessary strain on head gaskets.

Thank you for the offers. If I need anything I will get a hold of you. But like I said, it'll be a while before I can do much with it. Can't afford to have it down right now with getting this grain hauled. Also talked yesterday, sounds like the 93 might be going back on the road this spring to pull the enclosed trailer for the pulling tractors. Which excites me lol, I love that truck.:rockwoot:
 
Can't remember, did B models have issues with the exhaust manifold bolts breaking off in the head?

Two reasons for me. It makes funny noises that can't be g good for the longevity of the motor and below 1200rpm it bucks and surges for some reason.
 
I've driven a thousand if not more 3406 variants. 1000rpm is not a happy spot, but 950 to 1350 is supposed to be the rated torque curve according to cat.
People are also scared of TEL but they will do that for years without coming apart.
 
I can't believe how many 33 and 34 exhaust studs we do. They are all in CAT equipment. The 33's suck. Who in there right mind would put a injection pump right up against a hot exhaust manifold? Never understood it.
 
My dad has it figured out. Of course he is an owner operator so he has the time to do it. But when he notices a manifold gasket starting to leak, at the end of the day he soaks the studs in PB Blaster. As they cool it draws the PB in. After a few days they'll come apart no problem.

He'd been doing this on his 3406c since he's owned it for about 10 years, replaces exhaust gaskets about every 2 years it seems.

This 6nz will pull down to 1050-1100 and work. I don't do it thoigh 1250-1500 is my home.
 
i still find it odd that they went with only two 3/8" studs when they were using three 1/2" studs on the manifold of the 1693.

You can do what jfaulkner did to his and drill and tap them to accept a 7/16" stud or bolt.
 
Some of the problem is expansion joint locking, the joints can't move as they should and the manifold expands in one direction until so studs shear.
