4BT Diesel pro's and cons

[JB Fab]

It does open up a whole new world of possibilities being able to bolt on hydro pumps, air compressors. Just need to have 20 forward speeds to keep it in its powerband.....

So what Jon's saying is I should have gone diesel with 24 fwd gears the past 19 years!! Haha

Lol ..Not the way you like to drive Mr. C! This thing is a tractor (7.56 axle gears)

I have seen the Bronco you are looking at when he took it to some of the local shows, its on the expensive side but he did a really nice job on the whole build. IIRC the interior is already dynamated, or was it just the top? , so I dont think you will do much to make it significantly quieter. A quieter muffler if the exhaust is loud will help some, bio diesel typically has less fuel knock and the station at Butler Market and Boyd acres has it at the pump. You might be able to play with timing a little and also the intake as the air filter setup he has on it creates alot of turbo noise so that will all help but not drastically.

Overall its one of the few Broncos I have seen around here that I would buy if I had the money in terms of being done right and not just lipstick on a pig.

... Funny I don't think mine shakes .. But I'm a diesel lover.. If I lived on the Golf course I don't think I'd like one, but In My World I love them. & The injection pump I have on mine now I don't think it stinks. But the one I bought it with had been turned up .. & iT SURE BLEW bLACK SMOKE .
.. I'll swear I could cover up the building on the side of the road . & I'd turned it down when I put it into my Bronco.
.. Mine doesn't even run a fan blade.. Summer time yes it'll get hot but only about 2 minutes with the cooling fan on & it's cool .
.. Mine just seem like I added any extra weight into the front. But that is a little off point because I bought some Rough Country front coil springs from a member here ... EL Kabomg I think .. They are as good as I could have ever purchased .. Mine handles just like it did with the gas motor. I can't tell it 15lbs heaver in the front.
& I don't think mine shakes . & I think that was my biggest worry.

If you ask about swapping any other brand of engine into a Ford, you'll get harassed. Unless it's a diesel. Then you get praised.
It's a strange world we live in.

Diesels get a pass. Many truck diesels are not made by the truck manufacturer. Domestically, I think late-model Fords are the exception

Ford (pre-6.7) => Navistar
Chevy 3/4ton / 1ton=> DMAX (Isuzu/GM joint venture)
Chevy Colorado => VM Motori
Ram => Cummins
Jeep => VM Motori
Foton => Cummins
Nissan => Cummins
Old IH scouts => Nissan

OTR trucks => Cummins, CAT, Navistar, etc

You forgot the small Ram also gets a VM
Old Dodge also got a Nissan.
Jeep had a factory Perkins option at one time, available in the states too.

For OTR trucks, I think Mack is the only one that only used there own engine.

Forgot about the EcoDiesel

Dodge has a Mitsubishi diesel in '78-79 D-series trucks.


A fun fact: Ford sells a variant of the F-350 in Brazil called the F-4000. It's basically a standard F-350 dually with a small diesel, typically a Cummins 4BT or ISF2.8

What do you have for motor mounts?

 

[Pa PITT]

.. Well my motor mounts are the stock cummins block parts . & I built the section that welds onto the frame ... & I used nothing more than STOCK GAS 318 PAD RUBBER MOUNTS . THEY are about 3/4 inch thick. Seems like they have a 3/8 bolt offset top side & bottom side .. THOSE OLD RUBBER MOUNTS RAN FOR several years in dodges trucks ..
I expected them to be really rough but not. Everyone was telling me I needed to put in LIQUID FILLED mounts to stop the vibration. I don't think I'd have ever know the difference . .
.... I do believe my 4BT is louder than my 2000 24valve .. & I'M SURE IT'S LOUDER than my 6BT 1989. & IT's louder than my IH 1086 with the 414 that's supposed to be the same motor as the 6BT .
I have a muffler shop stock pul off Ford muffler on my Bronco . & a turn down .

The Ranger had a Mazda or Mitsubishi Diesel in the 80s as well. Depended on what year it was.

 

[JB Fab]

I used the Lord liquid filled mounts on both of our 4BTAA Broncos, as long as you use the correct frequency transmission crossmember mounts the vibration is not an issue. It is also helpful to turn up the idle speed just a bit.

Did something similar.

 

[JAFHR]

I have one in a backhoe, love it. But no way I want one in a vehicle. Noisy and shakey, the vibrations are the out for me.

I was very surprised but it actually did not have vibration that was felt. It did of course shake like crazy when you shut it down. Like all Cummins do.

I'm hoping to negotiate a good deal for me on the rig. The interior is dynamated but there is available a full firewall sound deadener and something like a sponge or foam that you can put on the inside of the top. Tom's broncos has these and say it works. Thanks for the referral on fuel. We will see this week if I end up getting. It is certainly different and a great driver.

Pro: mechanical fuel injection, one wire to run, Biodiesel or SVO.
Con: Loud, shakes fillings out and heavy. Not enough wheel speed when your geared low.

Mine has been extremely reliable. Bronco would sit for couple months with battery tender and It’ll fire up on a turn of starter. Every single time.
