Re: Loadmaster '47 COE
 

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!

Re: Loadmaster '47 COE
 

OK, so lesson learned on air bag systems: be very careful on mounting to insure bag does not rub metal. Rubbed a hole in my passengers side bag causing a loss of pressure on that side. The truck dropped to the bump stop but I was able to limp 20 miles to home. No sharp turns and a few bumper grinds got me home safe and sound. The ironic thing is the bump stop is what I was rubbing on. Had I not had it in place I would have been stranded for sure, but had I not had it in place I would have not had the issue to begin with. Had 2 extra bags so all is well now.
Picked up a compressor today for $25. How it's time to find or build the other components.

Re: Loadmaster '47 COE
 

Damn man! Glad you got home safe without damage to the ole girl. I've got a clearance of about 3/16" between my shock and bag. I don't know if it will ever touch it during a ride. It doesn't touch it no matter what ride height it sets at when setting idle. Where did you find that compressor for $25?! Nice score. If I hadn't already spent the benjamins on my viair comps I'd be lookin for an engine driven compressor option. Next build maybe.

Re: Loadmaster '47 COE
 

Rob, great work! It looks awesome laying that front bumper!

Re: Loadmaster '47 COE
 

Nice save. Nice score!!

Re: Loadmaster '47 COE
 

I have had electric compressors and the last 3 cars/trucks had edc. never again electric!

Re: Loadmaster '47 COE
 

Truck gods were upon you! I'll have to look into an EDC sometime as well.

Re: Loadmaster '47 COE
 

Thanks all, Chance I got the compressor at Ed Powell auto salvage, it's a local yard and he has a small building full of compressors of all types. If you can't find one local when it comes time let me know and I'll hook you up.

I've been checking on the other parts needed to complete and it looks like around $120 more should do. Of coarse that does not include a mounting bracket for the compressor itself, that is something I will need to fab up myself due to the alternator location, which is now in the old AC compressor location. So this is the location I have to work with, I have 2 options: I can get a combo pulley for the alternator and drive the compressor off of that or remove the tensioner, mount the compressor in it's location and use it to tension the main belt. If I go the second route I will need to buy a new clutch for the compressor and a new main belt. If I go the first i will need the combo pulley and a new V-belt. The first route is a little cheaper but I only have a 4 rib belt running the alternator verses a 6 rib main belt.
Looking for input or other ideas on this one.

Re: Loadmaster '47 COE
 

I like the option of replacing the tensioner with the compressor. One thing I am researching is if the tensioner function serves any other purpose beyond applying a specific tension to the belt. Thinking theoretically...does the tensioner also flex and absorb pulses in the belt system that may damage xx component. I am probably overthinking this. If I come across something I will chime back in.

One variable not evident in the pictures is which location is most possible to fabricate a solid stable mount? Might influence where to put the compressor.

Re: Loadmaster '47 COE
 

Looking over my post I was not real clear. In both cases I would need to mount the compressor above the radiator hose in the area of the tensioner, if I go with the combo pulley driving it off the alternator it will be more to the right side. I'm going to pull the covers off this week-end and get a better idea of what I have to work with. I also realized I have not removed the covers since before my road back in April of last year, just goes to show, modern drive trains require very little attention.
Rob

Re: Loadmaster '47 COE
 

I had my compressor mounted solid on the frame in my Jeep. Using a v-belt, I made my own spring tensioner on the slack side. Offroaded 5 years with that setup never lost a belt.

Re: Loadmaster '47 COE
 

Thanks Rob, I'll be in touch about a compressor in the future.

I think the 4 groove belt will be fine. The alt pulley is much smaller. I think it'll I'll be under driven enough that you won't have issue. I know, it's only a hunch but I like that idea best. I would try it if it where mine.

I also like lowers idea. I was actually thinking about that when I was looking at mine with thoughts of engine driven comp, after I read your og post about it.

Re: Loadmaster '47 COE
 

Hey rob just checking in on your progress. It's amazing that we work in the same plant and see each other as little as we do. Well cudos on the pump find and can't wait to see how it goes in. Also can't wait to get out to finish my cab as I am sure the space it is taking up is needed. Again thanks for your help bud. I got a little done on my bed today! It's got me excited for sure!

Re: Loadmaster '47 COE
 

Some parts arrived yesterday and I got a little work done today. I bought the rear helper bags off E-bay. The bags are a shorter stroke then I expected but I'm only using then for heavy loads so I don't think it will be an issue. You can see a comparison in size. The mounts on the other hand are very sturdy and will work good later if I end up lowering the rear. I also received my new clutch for my engine driven compressor project. I took 2 pieces of plate steel I had, welded them together and milled some slots in for some adjust-ability so now I need to start on the mounting of the main plate. I also removed the compressor head and tapped both ports for fittings to be installed later.

Re: Loadmaster '47 COE
 

As a thought, I had a alternator running a V belt pulley on the drive shaft on a 34 ford back in the 70's, looks like you have a lot of room under the bed to mount a York comp.

Re: Loadmaster '47 COE
 

OK, so I have been making a little progress on 2 projects: On the speaker panel project I have mounted the grill using 2 small hinges and a piece of nylon strap I cut from an old folding chair bag. I also added a magnet I pulled off the fridge to hold it closed. Works great and cleans things up a bit. I'm also back on the engine compressor mount project. Working on building the mount. It will all fit but I will need to add a smooth pulley in place of the groved tensioner pulley to keep the belt from rubbing the lower radiator hose. I will need to mill 1 ear down due to the mounting leg of the compressor mount. I will also need to support the plate from below. I think I can use the alternator mounting tabs as pick up points for the lower legs. Of course I will also need a longer belt.

Re: Loadmaster '47 COE
 

The box behind the speaker grill looks good. Did you weld it in Rob?

Re: Loadmaster '47 COE
 

Thanks for the thought Bluejeep, that would have worked except mine had to be mounted horizontal because of the floor of the cab. The top of the compressor in my case will be about the mid-pulley point of the unit shown. For the price that would have been a bargain compared to the hours I have invested in this design.
Hey AD, no for the speaker grill it is held in by rivets, I could not use screws due to the box mount flange. The box is held in place by 3 screws and 1 rivet.
Rob

Re: Loadmaster '47 COE
 

Your speaker panel cover looks great. No one will ever know anything is behind it.

Re: Loadmaster '47 COE
 

OK, so I now have a working EDC. I had to make some adjustments on the mount to get the belt to align. Speaking of belt, as it turns out I can use the belt I took off to drive everything except the PS pump so now I have a spare for emergencies. I was able to reuse the idler pulley I removed during the alternator relocation and mount it to the modified tensioner which now holds the pulley to the inside and is fixed in position. I been testing the system for about 200 miles now and except for a small leak in a fitting somewhere on the tank side all is well. For power I can go from 0 to 130 PSI in about 1 minute at idle and cut that time down to under 30 seconds at around 1500 RPM. I now have the system on a toggle switch but I think I will switch to automatic control in the future. Total cost for the addition of the compressor to the existing bag system $237.

Re: Loadmaster '47 COE
 

Kewl! Glad it is working out.

Re: Loadmaster '47 COE
 

It's all gorgeous Rob!! I really, really wished I didn't have these electric compressors here now.....this idea is in my arsenal for a future build no doubt. I love learning.

Chance

Re: Loadmaster '47 COE
 

an EDC will change your life, seriously!

a word or two of advice:

run a check valve between the compressor and the tank, or it will bleed back through the compressor. plus its just good practice.

run a stainless leader hose off the compressor and a high pressure water/particulate trap. EDC speed comes at a price, heat, and you will melt plastic line without some buffer for the heat like the leader hose. for the trap, some EDC will have oil blowby and the high heat of the compressed output can produce a lot of water in condensation.

and I did all my filling at idle, and the edc belt was always a bit chirpy, mostly because of the serious horsepower drain.

Re: Loadmaster '47 COE
 

That looks very nice. For a pressure switch use on of these. It is a pressure switch from a home compressor, they are about $35. I have had one in my Jeep for 18 years. Just wire it inline from switch to compressor.

Re: Loadmaster '47 COE
 

All very good points...great info here, thanks

Chance

Re: Loadmaster '47 COE
 

Maybe something like this? Using the home compressor switch is a good idea.
Rob

Re: Loadmaster '47 COE
 

yep just like that!

dont forget a leader hose off the compressor, that synflex will melt in a second!

Re: Loadmaster '47 COE
 

Great build!

Re: Loadmaster '47 COE
 

nice work rob, I'm more of an after tank trap believer. But both would be best. a steel tank condensates a lot, so regardless of how dry the air is going in, it will still condensate and put moisture going out.

Re: Loadmaster '47 COE
 

I have a water trap after tank on my Jeep and house very little water in either. But I drain the water from the tanks often.

Re: Loadmaster '47 COE
 

Little update: Another lesson learned on air bag system, be sure if your compressor is on a toggle switch to turn it off. Got distracted with the compressor running and a couple of minutes later...boom. Blew the line leaving the compressor off. I figure I had around 300+ PSI based on the run time and how much I had to bleed from the tank to bring the needle off the pegged pin.
I will be installing a new fitting and and automatic control switch next. On a happier note, I installed the visor which was on the truck when I got it. I can't find a manufacture name on it so I don't know who made it back in the day, but I would guess it's 50s era correct. Stainless steel ribbed with polished center section.

Re: Loadmaster '47 COE
 

Luuuv visors, I found a local one for dirt cheap but of course I can't be spending money right now :( nice save on the compressor, scary biz there. I have a pressure switch and also a toggle switch. Furthermore I have a big toggle switch to the relay that runs them. So if I'm doing some maintenance in the back, I can kill the master power to them.
I was going to put a blow off valve in the tank but never did.

Re: Loadmaster '47 COE
 

Darn Rob, glad no components got rearranged in your air system. It's easy to make a mistake like that, and good idea on a pop off valve aswell 99. I love the visors to. Mine didn't have one, but I will be putting one on it....bout 450.00 for aftermarket. A local yocal has I severely rotted out 50 3/4 ton Chevy with a good visor on it, only thing on the truck that's left in good shape. He wouldn't sell it, but quoted maybe 600.00......I laughed. The truck doesn't run. It's been setting and rotting for years, guy says he gonna redo it, but how's he gonna do that when he doesn't go outside, work or anything, whatever.

Re: Loadmaster '47 COE
 

Visor looks good. They make the trucks look chopped. I have a Fulton Sun Shield mounted in the lowest setting.

Re: Loadmaster '47 COE
 

Looks good.
I was walking the turlock swap meet last weekend and the cheapest I could find a visor was $150 and it was rough...

Re: Loadmaster '47 COE
 

whoops re-type...too many tabs open

Re: Loadmaster '47 COE
 

Yikes ! sweet build ... theres a square d version of that pressure switch that has the on/off lever on it and is adjustable with about 60 psi or range. so On at 160 off at 210. I mounted the pressure switch box directly behind the seat where I can reach back with my left hand and flip it on(automatic) and off when I want the compressors off. I can also hear the switch click on and off which is super helpful. There are also 3/8 press loc pressure relief valves that go at 220 that no bagged truck is complete without.

Re: Loadmaster '47 COE
 

Thanks Epon, I'll look into that.
Rob

Re: Loadmaster '47 COE
 

OK, so I always thought the Daytona Superbird with the wing on the tail was a cool looking car, so I got to thinking why not a superbird COE? For sure I will be using these pieces on the rear of the truck. Thoughts?
