Pad mount in place of J mount 5.9 ISB

[BennysTire]

Has anyone put a pad mount on the exhaust side of the motor there the alternator J mount is?
Or, are any of your motors already set up this way?

Why? have one laying around??? Looks like too much work, to me.

I have a few left

Thanks for the offer. But that alternator is too small for my application. I want a pad mount. The alternator I am using IS available in both pad and J, but it puts a significant pull on the belt. I was hoping the mix of a more solid mount and a dampener pulley would help it out. Worst case I can do some sort of brace on the J mount...

Bosch is 200 amps- which alternator are you going with? 40si? Not much room around back in this small motor.

I'd work about the pull on the bracket when loading that alternator, too. There is a cast bracket available, but not adjustable, IIRC. There are 2 sizes of J mount, differ at that outside bracket pad by .75 in or so.

430 amps@ 12v DC. Let me get my DC wire selection chart and see what sized cable I'd need.....


55si alternator/mobile welder

I like the Bosch as it produces majority of output at idle.

My previous setups all were around 450A with duals. I run 4/0

Man that thing is a beast. Found on firetrucks. and only $1900 lol.

Give adelmansco a call, he'll have a pull if you haven't sourced it yet.

I got mine brand new from a local shop for 1750

I KNOW you know what you are doing, but why so much juice? I realize it's your mobile shop, but wouldn't a little honda genny fit the bill? Elucidate me, please.

Air compressor? Those come in gas models. I'm stumped?

[BennysTire]

Previous builds utilized 6-7kw generators for the whole setup. It was JUST enough to power a 5hp 240V compressor, meaning I couldn't run any other equipment while the air was building.
The bus needed to remain running for heat and exterior lighting (all 12v)
Then I switched to inverter power. Ran all equipment EXCEPT the compressor. So the compressor ran off the generator alone. An improvement, because I didn't have to wait anymore.
Recently got a gas powered compressor and a smaller 120v compressor. Now I can run the 120v along with the other equipment simultaneously on inverter power. I only need to fire up the gas compressor to do larger truck tires that require higher volume air supply for 1" gun, etc.
I'm trying to reduce the number of engines running! For some jobs, I had bus, generator, and compressor all chugging along at once!

Thanks- I hear you. A lot of ways to skin the cat, you are looking for the least painful method. Time= $$$

I just hate all the mechanical energy waste. Diesel>alternator>compressor motor>air pump.

I was thinking about a PTO-driven compressor....

Yeah, before I decided to stick with busses I was going to get an Isuzu NPR as I could have got a PTO driven rotary screw compressor AND generator.

I could put a PTO on the bus, but not (effectively) on an AT545. Yes, I know, swap out the trans since it's a dog anyways...

I use a bunch of electricity, both 12V and AC. So I'd need the whole PTO deal and still need a big alternator. My trade, by nature, produces a BUNCH of wasted energy. There's not too many ways around that fact without trading for time. And yes, time is $$$[emoji57]

the tu-flo 550 bendix is like a 13 cfm compressor... why not just add bigger aux air tanks on a protection valve past the brakes and use the onboard compressor? even pounding away with a 1 inch impact id think youd have enough air.. the governor cuts out at 120 , most air tools like 100 or less.. you can even set the governor to pull back in at 110 instead of 100...
maybe upgrade from an AD-4 to AD-9 air dryer if you dont already have the AD-9..

I'm sure you've been through all the options.

What would be the downside of a nice HD ambulance/rescue ? Looks to check a lot of your boxes: It'd be wired for your safety lights, genny, PTOable big trans, storage, free sharps

Sold for $2500. zillion hours, but looks mean.

[BennysTire]

Yeah, been down all those roads. Ambulance too small.
Air brake compressor not enough CFM or pressure.

Howdy Bud --- Just noticed you are looking for a pad mount for your alt. Not sure if this will fit your bill but it is what I used on my Cummins 4BT (was made for a 5.9 but fits). These guys can be hard to communicate with but the product was very well made. It mounts both an alt (mine is 250 amp) and an A/C compressor on a single custom pad.

wow what kind of CFM and pressures do you need? I know you can turn up the governor safely to 140 off and 130 on. and not hurt anything in the brake system.. are there tires that need more than 120?

I noticed a sticker posted above the steer tires of a Greyhound bus the other day that read, "130 PSI". First time I've seen a recommendation for such a high pressure.

Typically 120 to 130 is the max on the tires I fill. But if the compressor is at 130 (or even 150) the last 20psi takes forever to fill, as the pressures are nearly equal. I usually run 180.

As far as CFM, around 30. 1" gun is thirsty, and I am usually airing up tires while changing another...
