K30 Cummins Dually build

[Dieselwrencher]

Nice work. I still need to do a front shaft on the Excursion and I was wondering how much of the ford flange had to be machined/removed to go on a dodge flange.

[legendman]

Since it's too dang cold I figured I would do some reading while waiting for warmer temps

[legendman]

Some videos to add...
First one is when the timing was off after I sheared the key on the IP.
Second all back together with correct timing, sounds much better
Third is a cold start after sitting a week 40 degrees out and fired right up.
Couldn't believe how easy it started, ole 6.2 never would have started like the 6bt does.

Got my mud flaps for the dump body today, think they are gonna need a little trimming lol

[66LSx]

Keep at it! My last project was a 47' Ford 1.5 ton with a cummins 6BT and Roadranger 10 speed....

Yours is looking great!

[legendman]

Some updates....

Got it registered Saturday, now it's legal for the road....if I ever get it on the road LOL

First... painted the inside of the cluster..

before..



after...



Replacement radiator off epay that has to be replaced again because the tanks have cracks on them argh



Got my mud flaps mounted, had to trim them a bit but for $11 each I can't complain..



To help out with the wiring I printed up super sized schematics..



Now here is the trouble when you buy a truck in pieces and don't get all the correct parts, this the parking brake cable that came with the truck in a box with a bunch of other parts, obvious that it is not going to work so I had to order and replacement.



That's it for now, working on getting a replacement radiator, all I have to do is take a pic of the bad and send it to the parts place and they will send me a new one, easy enough I guess.

[Dieselwrencher]

Looking good. Ebrake cables can be a real bugger on old trucks because they're always hacked off or not right. Good luck on the radiator. I had a fiasco with Classic Radiators on Ebay and after 4 damaged radiators I just got a refund and purchased one at my local Napa.

I am waiting on $$ to pick up a 2nd gen radiator off fleebay right now. If you don't mind me asking, what brand is yours? I don't want to run into the same issue. How does the quality of the core look?

First one I had was a silla, $180 on epay, second one was from prime choice auto parts on epay, hard to tell the difference in quality but the prime choice one was $65 cheaper.

[jbclassix]

Ok, I was watching one from prime choice and one that is a Vista Pro brand. I got the part numbers off my least favorite parts web (rock auto) and then found it on epay for cheaper. I miss the days of getting a quality rebuild locally for way cheaper. Thanks for the info.

I feel your pain Jeremy. Have you had bad experiences with Rock Auto?

I got a master cylinder for the K30 a while back and it looked worse than the one I was replacing.
Plus unless your ordering a bunch of stuff the shipping charges jack the price. So I just find whatever I need on epay and order it.

[jbclassix]

Legendman hit the nail on the head. If I'm expecting poor quality, I'll just buy it cheaper on fleebay.

Did you contact them about it?

Everyone I know that has purchased from Rock Auto has had good experiences. They accept returns easy and everything. I was leery of buying from there but I've been nothing than happy so far.

It was only $20 so I used it as a core and got one from the local parts house.

Big update...

Got it registered and insured, been doing some test drives on the road and found I have a serious death wobble issue. So I started with getting new tires and rims for the front.
Figured maybe a tire was out of balance or a rim was bent.
Well after cleaning up a pair of rims I brought and putting different tires on by hand.
I used airsoft bbs to balance the tires and after all that the death wobble was still there.
So hunting around I found worn king pins might be the issue.
For $170 I picked up king pin rebuild kits for both sides from East Coast Gear, all dana/spicer parts.



All ripped apart, and need to find something to get the king pin out, I heard it can be a really PITA to get out.



Luckily the hardware store across town had the 7/8" allen wrench I needed for $23.00
Hope I don't break it.



Well the l/s pin came right out with little effort, r/s required some gumption to get it out.

Lower bearing races were a bugger to get out, had to grind the race a bit.



What happens to create the death wobble is the spring looses tension over time and allows the plastic bushing to jump around.
You can see the spring height in the next pic...
r/s on the left, l/s spring in the middle and new spring on the right.



Used my seal / bearing drivers to put the lower bearing race back in.
Brought these over 20 years ago, glad I still had them.



Getting the r/s back together..



Well after that 2 day chore I can say the death wobble is now gone.

Also wired up my O/D and lock-up for the 47rh so I could really test and I am tickled everything is working.
Now to get cracking on other stuff on my to-do list..

Some more updates...

I picked up this winch bumper a while back and never really liked how it looked.



So I sold it for $150 and brought a decent stock front bumper for $25 to use until I build the custom bumper I want.



Also painted the l/s door panel, they were a faded gray color.



A while back my power steering pump was leaking so I brought a seal kit for it and attempted to replace the seals. Ripped it all apart and put all new seals in and put it back on and it leaked worse than before LOL.
Went to autozone and got a rebuilt for $55 slapped it on, no more leaks LOL
Guess I should checked the parts stores first DOH

[COS399]

The kingpin spring looks like the one I found on mine except my wobble was limited to LH side. I am going through both sides but I made the mistake and ordered up my parts separately instead of ordering up the entire kit like you did. Keep up the good work!

[Dieselwrencher]

Nice work, the truck really looks good! It is a good feeling to have it legal, and drivable!

First time I ever driven anything with a 6BT in it, now I know why this swap is so popular.
Mine is bone stock and I gotta say it's got some balls, should be real fun once I start adding some mods.

I have a question, how did you get the intercooler and radiator tucked into the front core support? more pics? I am in the process of doing the same build, any tips or pointers are greatly appreciated.

Thanks

I cut the supports out...



Have to finish it up with some new supports running from top to bottom, I am just going to use some flat bar steel to stiffen it up.

[Iceman3005]

Nice! It looks like you didn't have to cut into headlight sheet metal, just supports? Most builds I see they cut the supports and headlight sheet metal, and I am try to avoid that. Plus you where able to use dodge radiator, fan shroud, and fan. That is what I love about your build and hopefully I will be able to duplicate that.

This is my build.

I couldn't use the Dodge fan and clutch, not enough space between radiator and fan.... I found out the hard way. Had enough space on flat ground but the body twisted enough on some uneven ground that the fan took out a brand new radiator argh went with an electric fan.
