Punch in H model with air start on google it’s a great little video

have to say the H model may have been a quirky looking with the little bubble nose ; at same time a different  all around truck. higher cab had visibility  and shorter cab 

[mechohaulic]

thanks for video: i will log off here and check it. wouldn't go through for me on here. 

[mowerman]

Ha ha the closest I’ve ever got to one one except that shows I sat in one in a wrecking yard somewhere around 1970 as a young kid.. Bob

No, I didn’t think you could open it. I was just showing you which one it was.

Don't look now !!! we are going off topic AGAIN.  I put short version of me and a H67 on frozen clutch topic. yrs back two old timers came to waterbury mack from Maine to look at a H67 single axle for sale. dead winter cold ; tow truck hooked to H model. I'm in the H. boss and two buyer watch as tow truck pulls me to start. tow truck stops ;I didn't . the H had a twin stick duplex. everything so cold  i thought both sticks in gear:: aux wasn't .SMASH  into plate on wrecker with the bubble nose. my boss (big guy) races over to me : "get out of that truck you fu--in assole. two buys never said a word; got in their vehicle and left. so summary:: my H model story didn't have a happy ending LOL

Doesn’t sound like there was a whole lot you could do about it … Bob

A little bit of airstart fun

[Onyx610]

What do you do when it’s having a hard time starting and you run out of air?

[mrsmackpaul]

Well you fill it up with air and try again

I really cant imagine a air start is much good in a cold part of the world, the air valves freeze in Australia at -5 C which according to google is 23 F and it gets a lot colder than that in parts of North America I believe

Apart from the novelty air start is a bit of a pain in the neck, battery technology has improved so much that air start has been made a non event even in tough going areas of Australia

Well I guess I was thinking more along the lines of if air wasn’t available in the location you may be at in that time. So essentially you are screwed. Still a baddass system. 

[mrsmackpaul]

Nah, there's a hose with a fitting to drain the tyres to recharge the tank, three tyres apparently gives you enough to get here going

Once your started you refill the tyres from the trucks compressor 

As I said a pain in the neck

[Onyx610]

Ahhhh ok, makes sense to be able to steal air from the tires. 

[HarryS]

Still quicker than recharging an electric.

[Freightrain]

I can get 8-9 seconds of cranking on a full tank.  Since mine lives indoors all winter I haven't had the need to see if it will start in the cold anymore.  This video, I only had like 80# in the tank to start with and it starts faster then you can release the button.

I may, just for giggles, leave it out in the dead cold one night this winter just to see how it starts, unaided.  

[mechohaulic]

one of the reasons air start vehicles had larger volume  air tanks. as with all mechanical devices ; each one has it's down fall. back then engines could handle the forbidden  ether can. many of winter road calls for no start / no air. 

[Freightrain]

Is be curious to see what the actual gallon size my tank is?  It is an alum tank from an R model.  One of the larger ones I've seen, length wise.  It's hanging under the bunk in my signature picture.

I've see ones that are near 1/2 as long as mine.

Just wind in  the Maxis and pull it with a car and a rope : 

[mowerman]

Once you get familiar with your engines performance, you know exactly what it’s going to do and when… when Bob

[mowerman]

My tank looks to be around 90 gallons if off a kenworth

[Big R]

Thanks Larry, I wish mine was air start. Pain in the ass or not mine is for fun. Too bad that thing starts so fast sounds better when it takes longer.

Apparently there was a 1 start, 2 start and a 3 start tank

The single start tanks are really short 

Maybe only 6 to 8 inches of flat if measured length ways

2 start tanks are about 12 inches of flat

3 start are longer at a guess 18 - 24 inches

I reckon on some old B models I have seen even longer again

So, the tank still had enough air in it to start it today from last Monday. I thought that was really cool. Got her home today. She runs really nice and the dump body works great. I might just throw the good cab on this one to be honest.

Can see the giant air tank behind the drivers side fuel tank.

So the door tag says “B 613 S”

Anyone know anything about the 613 S part?

[Craig N]

What’s the difference between these two wheel seals?  Is one oil and one grease?
