Loadmaster '47 COE

[99 to Life]

I have 2 450's filling a 5g tank (technically 5 gal tanks aren't 5 gal) it takes 4-5min to fill zero to 150 psi. It seems like an eternity at times. Always run two comps and 5g tank if you can, if you can fit 1 8gallon tank, might be a good option or yah 2 fives, but to fill two fives is going to take close to ten min from zero to full. I get not even two air down/up until the comps kick on.

I'm running 2X 480's 250psi and 2X 4gal. So far I can lift to 5"@120psi with the compressors just kicking on when I am letting go of the air sw and it recovers in 1-1.5 min.

I've been making some progress on the wiring for the control panel. I've also added 2 more switches to the system: one for future rear lighting (reverse and bed/cargo) and one for the trailer mode control. All the connections are both soldered and heat shrunk. The complete wiring will be on a single connector for a little more ease of maintenance if needed.
I also received my new ignition switch, it's smaller then the standard aftermarket universal units which have an interference at the lower part of the dash.

Love your attention to detail!

Fast Toys looking good. " Soldered & Heat Shurnk " I know about heat shrunk insulators, please how you hold the wire while you solder. Also why solder, when all aircraft manufactures only crimp & heat shrink? Thanks in advance. Nut Case

[47 Fasttoys]

I just lay some pliers on the wire and let it hang over the bench. I crimp them first then solder, why? I don't have the correct tool for the perfect crimp, I just got used to this method and it works for me.

I do the same thing Rob. Overkill, I guess, is my name.

Did my eyes deceive me when I saw your truck in Street Trucks mag.

[47 Fasttoys]

Your eyes did not. Yes, it's in the readers rides section of the magazine.

I've gotta get plugs and multi colored wire. Or, maybe I'll just get a kit. Where can a fella find sealed plug ins and such like used in automotive?

Looking good Rob, and soldering is a good thing. Nothin wrong with good solid connections.

[rusty76]

I thought so. Looks just as good there as it does here. Congrats..

[garmar]

This has been an awesome build to follow. Amazing job and thanks for sharing it with us.

[47 Fasttoys]

Thanks all, Chance for the wire I keep all the left overs from projects I've done in the past. I've done 3 rewires and 4 EFI set ups so I've built a little stash. For connectors Weatherpac brand makes a nice kit with sealed connectors. I also buy stuff from All Electronics .com and Summit/Jegs etc.. Some of the good stuff is not in the catalog but can be found online with some searching. Both the 15 pin connector set and the new ignition switch came from Summit. They are both name brands and known quality products.
OK, so now I have a question; How in the heck do I get a picture to load into my sidebar? I have tried following the instructions but always get the message blocked by administrator or something like that. I know it's truck porn but my wife says it's OK.

rob, you want an avatar pic? they have to be very small and low res. so your pic is prolly too big and its not letting it load. I think they tell you the specs that image needs to be. If you need help resizing, you can email it to me and I can resize it for you.

[Nut Case]

Fast where do you get the uninsulated connectors? I have to cut off the hard plastic insulators, crimp, solder, then slip on the shrink tube. If you can share were to get the uninsulated connectors it will save on step in the process. Thanks for sharing. Nut Case

[47 Fasttoys]

Good question Nut case, I do the same as you and pull the plastic insulator off. I did do a little searching and the terminals can be ordered without the plastic at: http://www.jameco.com/Jameco/catalogs/c273/P143.pdf
I have not used this company.

I have purchased from Jameco before and they're good to do business with.

But, what I've found is that uninsulated terminals are considerably more $$ than regular ones, so I do the same thing and cut off the plastic, crimp, solder, and heat shrink them. I'm used to it so it doesn't take that much longer...

[oldman3]

Noticed you got you avatar up, looks good...Jim

[47 Fasttoys]

Thanks Jim, After doing a little research I have decided try building a belt driven compressor for my air bag system. Space is a little limited and some modifications will be required around the engine covers etc..but the idea of high CFMs and the ability to run air tools appeals to me. I know there are air driven hydraulic systems out there (we use them at work) which would not require an electric motor and could be used to lift a tilt bed later so that would be an additional benefit . Ah yes, more things to figure out, that's half the fun of it all.

[Nut Case]

Fast: Thanks for the data. In my youth I drove trucks with air brakes, they all had engine driven compressors. I'd check large truck salvage yards for the compressors and such, I'm sure you could fab. a bracket that would tie into your engine. Nut Case

[lower50's]

This is the type of compressor you need its a York style ac compressor. Big rigs still use them but look for a '70-'80's full size ford or dodge truck or van. I had one on my Jeep for years. I could run an impact.

[Chance48]

How are those lubricated if no coolant and lube are present? Does it have a sump or engine oil feed?

Great idea Rob! That's a huge component to fit but if anyone can it'd be you.

They have there own oil reservoir. I just used air compressor oil. You can mount them sideways to strait up.

[47 Fasttoys]

Thanks Lower 50s, yep that's the one I've seen on a few posts about the subject. Thanks Chance, I'm not sure how well it will fit at this point, but heck, if we all just waited for someone else to figure stuff out then we would all be driving Honda Civics. I'd be willing to bet I could pick a team of 10 guys on this Forum and build just about anything automotive starting with just a few tools and an idea.

[Chance48]

I've owned a few rigs that where used in my business and never had an issue with a/c besides adding a lil freon to one of them. I did not know that info. I can imagine those are some very robust units. Great ideas every where!! My brain is a sponge when I'm on here, always learning. I'm having good fun. Thanks!
