75 Dually build

[75Dually]

I got the engine slung in the frame rails! Small victories... I also got the new injectors ordered and the engine overhaul kit ordered. So pretty soon this should be a running power plant!

This truck has not been cleaned since LST. Now for those of you who were not able to go to this years show we got major rains on the last day, and we drove through them on our way home. So it's nasty and needs to be power washed something fierce! However that will have to wait until we get it under it's own power again.

I'm going to start getting the engine mounts figured out this evening, that should be fun...

Stay tuned!

I got the new engine mounts started tonight. I'm going to have to cut this plate down some as you can see, but this was just the first test fit after drilling the mounting holes. No the Chevy big block mount is not centered, I have yet to center and fix the position of the engine, but I will start on that tomorrow evening. Right now I wanted to get most of the steel cut and ready to tack in once I get the engine fixed in it's final position.

Stay tuned!

Let the rebuild begin! I got the complete rebuild kit in today, and yesterday I got in my new injectors. So I hope to get the rest of the engine tore down so I can start and at least get the long block finished this weekend. I'll take some update pics as I progress. Oh an for everyone that has given me suggestions, yes I will be doing the killer pin update first thing.

Stay tuned!

For those of you who build any parts of your truck you know that life has ways of throwing you curves. As you can see below there is some PVC pipe and a lot of dirt.

The story starts out with my wife working on Friday night, my youngest was out with buddies, so that left dad batching it for the evening. I called a good friend and went to grab some dinner. When I was driving out the drive to go to dinner I saw the whole front lawn was wet. I thought that someone left the front hose on. Nope there was water bubbling up from under the sidewalk! I shut the well pump off (yeah we are on a well), and knew there was some bad juju going on. Ended up getting dinner anyways... So the next day we got the sidewalk busted out, found out where the main water line was broken, and got it fixed.

The reason I tell all this is not for support, but that I was supposed to be rebuilding the Cummins!!! I was going to clean the shop Friday night, and then get busy all Saturday. I at least wanted the long block to be completed by the end of the weekend. So if all the stars get in a row I will start the rebuild at some level this weekend and hope to have it buttoned up very soon. That is once my lower back quits grabbing me...

Stay tuned!

Finally some progress. Tonight after it started to cool down I got into the shop and started to put this lump back together again. I got the cylinders honed, and then I went to work getting the new main bearings installed. The crank got polished and then went right back in with the new main bearings. Checked all the under piston squirters, check, and then started to torque down the main caps. Well almost... My light duty torque wrench which goes up to 150 foot pounds was in fine working order, but the main caps are to go to 176 foot pounds. I went and got my 250 foot pound torque wrench which is all electronically controlled, and it's battery was dead, UGH!!!

So tomorrow I will go get a new battery, and then I will torque it down to the correct torque spec.

Then I will get the cam back in, along with the new pistons. Should be a fun day!

Stay tuned!

Sorry for not posting for quite a while. With all my kids birthdays and work travel it has been tough to get in the shop and finish up the Cummins. However I got the internals all back in and freshened up. Tonight I got the oil pan cleaned up and the rear main seal casting all cleaned up too. It got to late for me to finish it, but tomorrow night I should have the gasket on and the bottom end completed.

BTW I would like to make a correction on the above post. The mains do not get torqued to 176 foot pounds, they are torqued to 130 foot pounds. That 176 was in Newton Meters. I always double check my torque specs before I do anything and found out I was wrong and reread my post and did the forehead slap! Well at least I did catch that... Ug!

One other item I enjoyed doing was the honing of the cylinders. I had not done that since high school, but with a good friend giving me some great guidance it turned out easier than I thought it would. Now for those of you laughing at me because you know how easy it truly is, just remember I'm a DIY guy and not a machinist or an engine builder. Either way it turned out great.

Stay tuned!

Don't know if I'm going or not yet. I will have to wait until that date get's closer to see if I can take the time off or not. I do want to go because I think it looks like a great show. Just wish they had not sold out so quick...

It's done! Finally got my side walk poured today. Oh and it kicked my butt! It was 100 degrees plus today. The reason it took so long is my wife works weekends (she is a charge nurse, and she works nights). So it has been tough to get a weekend when she is not working and the weather was cooperating. It's not perfect, but it is pretty close for us. I'll bust down the forms tomorrow.

Now I can get back to the engine build, again if the weather will cooperate! It has been several weeks with temps over 100, and that has just been too hot to work in the shop, especially with the humidity we have been experiencing. Yeah I know no sympathy, but this is only a hobby...

Stay tuned!

It's usually 112°F inside of my shop @ the end of the work day.
I get it.

We've had a cool down the last week but the month before that we had what yo just had and we're getting it back in a few days. Yeehaw. Nice work on the side walk!

[75Dually]

I have been working on the Cummins for the past couple of evenings. I got the head all redone, and then mounted back on the engine. Thanks to my engine hoist for saving my back! Tonight I got all the rocker assemblies mounted and the head torqued down. Tomorrow I hope to have all the valves adjusted, and then start to put all the other items back where they belong.

So some steady progress. I guess it is now time to get the engine slung back in the engine bay and make all those mounts. Now that will be fun!

Stay tuned!

nice progress!

Look at the clean and painted manifold! So shiny!

[75Dually]

I got out into the shop early today to try and beat the heat. I got the exhaust cleaned up and coated in a ceramic heat resistant coating. Then I got all the valve covers cleaned up, Yuck that was zero fun, they were nasty, but now are a lot cleaner!

I wrote a list of items I wanted to get completed this weekend. I'm about 3/4's of the way through it. Items I have completed so far: new water pump, new thermostat, install the front main seal, install the front cover, reattach all the fuel supply and return lines, purchase new rubber return fuel line, and supply line. Plus the 2 items above. Oh yeah I took the wife out for a really good lunch and some shopping she wanted to do. So yeah a very full day!

Tomorrow's list goes something like this: install rear main seal, install transmission mounting plate, install flex plate, and then the transmission so I can get everything in the truck for mock-up of the mounting plates. Oh yeah all those items have to be cleaned before installation... Build a Cummins they said... It would be fun they said...

Stay tuned!

It will be way more fun than that big block was! Nice work on it. All that clean up is time consuming. I know you pain.

Of all people you you know the time and the commitment it takes!

Cheers Ryan!

A major milestone was reached tonight! I got the engine and trans slung in the engine bay!!

Now the fun begins. I will start on the mounts first (engine and trans) and then work on clearance for the AC pump. Then I got to get the driveshaft cut down and the correct yoke for the Dodge trans. Then there is all that wiring... Yuck! Oh well it is just another job to do and check off my list...

Stay tuned!

Another good weekend in the shop. Been working on getting the engine fully mocked up and getting all the mounts made. I started last night by getting the radiator support mounted so I could see how the dual fans I got would fit. Which then lead me to see about how I was going to fit the intercooler. This is turn showed that I was going to have to use the Dodge radiator instead of the big block Chevy radiator. Bummer! I really wanted the extra capacity and ability to handle a greater heat load in the future. Ah well I guess I will keep it for a future update. I did however try and see if there was anyway I could use the Duramax intercooler, but it is about 3" too tall for this application, so I guess I will use the Dodge unit for now. The core support in these pics is super dirty because it has been sitting in the back of the shop since LST... Lubbock dust... Need I say more...

Today I got busy taking out the old transmission cross member because it raised the transmission too high. The weird thing is the mounting holes on the A518 lined up with the old Turbo 400 trans mounting holes. Too bad because I really thought it would be great to use the old Chevy mount, but no... So I grabbed some steel out of the rack and made a replacement. It was fun to build, and now I just have to drill the holes for the frame mounting and weld everything up.

Stay tuned

A quick question for you guys who have these Dodge transmissions. Which way does the the lever at the transmission go when it goes into park? Does it go all the way to the rear or all the way to the front? I'm going to have to build my own mechanism for the gear selector and need to know.

Thanks!

Nice work on it! I'm pretty sure all the way to the rear is park on these dodge transmissions. (I can crawl under my excursion later and verify) I made a bell crank type mech for the yellow 88 burb I did. On my 72 I went with a lokar cable shift set up.

On the trans mount I have made a new plate to bolt to the overdrive housing and used poly TH400 mounts several times. On some I have just modified the dodge plate and put the TH400 mount on it. I did this on my 40 Ford.

I actually have an auto world AC comp bracket for a VE I haven't used yet. This would mount the ac compressor on the cylinder head. They use a custom dual pulley they make to drive the comp. I just can't remember which pulley I have.

I did get a stock dodge compressor in the frame of my 72 but I had to do a lot of work to get it in there. It is really tight.

Looking good. My 88 still has the chevy 454 heavy duty radiator in it and the second gen intercooler. I can PM you some pictures if you want to look at it. I had Ken, at Autoworld, install it about 14 years ago. He did have to cut the two tubes, rotate them 180 degrees and weld them back together to make it work. Keep us posted and hope to see it in person next time I pass through Lubbock.
