Thank yall for the comments, We have found a few parts with a metal detector, and about half a mile is where most were found,, Some of the parts are small and it’s more trouble at this point to keep looking, I think I have enough to finish it. And yes I’m keeping all the air start stuff,, I actually would love to find a small parts rebuild kit for the starter, I aired it up and it was stuck, it blows air straight through, I took it off and got it lose , I might take it apart on a cold rainy day.

The vanes are probably stuck, just pull it apart and soak in diesel 

They need a huge volume of air to force the fins out and spin them 

Or at least on the ones I work on

Air goes thru the rotor part and blows the vanes out against the stator to seal them and then the rotor forced by the air as it is sealed up pretty good

Rebuild kits are readily available in Australia as nearly every Mack sold out here was air start up into the 90's

It is very rare to see a electric start Mack built up until the late 90's

Might try ASC in Texas, they had all my I-R stuff I needed.

That is an old model and parts may be thin to non-existent.

It would be replaced by a 150 of some sort.

If you take it apart, mark the parts esp case sections so you put back the same way around.

Simple devices.

back in 81 i was helping a friend out picking up a load of trees with the truck that would later try to kill me.

it was a 74 or 75 u model with air start. 

i got to the landscape yard rite at lunchtime. the owner directed me to park rite where the guys were sitting down for lunch. i shut the truck off. 45 minutes later the owner told me to fire it up as all the guys were napping and they only had a 30 minute lunch. 

i never saw a group of Mexicans move so fast in my life as when that air starter went off!!!

and the owner of the yard was rolling on the ground laughing his assterisk off.🤣

apparently he knew the truck had the air start, and wanted to teach those guys a lesson.

[Geoff Weeks]

All mine had air mufflers on them. Sounded "different"but not obnoxiously loud.

[mowerman]

mine has no muffler,,,,a buddy of mine was over for barbeque a while back he wanted to hear mine run,,,even after i warned him,,,starter was very loud,,he still jumped back around 4 ft.lol...bob

[Geoff Weeks]

I would park between my garage and my neighbors house. Muffler was mandatory for good neighbor relations. 

 I asked if my early morning starts were a problem, and they said it never woke them.

 If they had made an issue with the town, I doubt it would have ended with "it is his land, he can park whatever he wants on there and start it whenever he wants".

 Like a jake, a little consideration goes a long way.

 I switched to air start for the reliability, and the ability to easily start a hot engine that had just been shut off in the customs booth. Later I found being able to sleep all night with the engine off and the heater running in -25 F and not worry about if the engine would crank.

It was a rainy morning, so I thought I’d take it apart, actually all I need is the end gaskets , and I can make those, the vanes have scratches but not terribly bad,,, I’ll contact ASC and see if any thing is available,, if not I’ll clean it up and put it back together ( I did mark all the sections in the direction they came apart) . Thanks for the suggestions . 

[mowerman]

Sure don’t look bad at all according to the photos… bob

[Joey Mack]

It looks like a 1'' tire gun.. I always thought they looked that way, but with a gear on the end instead of the anvil..  

[Brocky]

I think everybody flinches when an air starter activates. I remember in about 65-66 on the college campus at Oswego NY the back of the library / book store building faced one of the big pedestrian walkways. After delivering his books a B Model Mack delivery truck hit his air starter. I do NOT know which was louder, the starter or ALL the girls screams!!!!!

I strongly recommend the lube injector pump in the air inlet. Either use MM oil or hook to the fuel return from the injection pump. Gives a shot of lube each time the motor is powered.

something like this:

No relation to the seller!

It had a line to the return,, the injector looks better. Yep a one inch air gun,,, wonder if the vanes are the same,, I got it free, Just messing around with it on a cool rainy day.

Geoff please where did you buy the air mufflers? I would like to fit onto my B75.

[Geoff Weeks]

Mine came with them, but I see them from time to time on E bay and ASC used to sell them.

ASC seams to have gone into more of makeing their own (old Startmaster) and rebuilding them over supplying I-R parts.

The air muffler is just a large "can" with slots in the side and filled with metal "turnings" so it could be home made with good results. also.

cheaper

A quick look-see on E-pay showed 4 (I might have missed some) and I posted the cheapest 2

[Geoff Weeks]

I had the 1st style, with I-R cast on it. the 2nd style may be an aftermarket part that someone is making.

Both styles have a snap-ring on the bottom so can be re-packed need be.

Harry, just noticed your location. there was one being sold out of India which may or may not be cheaper in your part of the globe, I didn't post it because here in the US it was more expensive than the other two.

It was on E bay with the search "Air Starter" . You have to wade through the air brush starter kits and the electric starters for "Chevy Bel-Air" to find what you need.

Harry, PM Paul MrsMack... He had said earlier that most pre 1990 Macks came from the factory with air starters.. He might know of an Aussie supplier????

I’m thinking pretty serious about changing my H67 over to air start , I’m going to put the air starter back on the parts truck and see if all the valves work, and try to start the engine, then I can take all of it off, the big lines will have to be replaced, I was getting bored, I need a 16th winter project! ( with no shop ! )

Many times they are made up with re-useable fittings, so just buy enough -20 hose and go to town.

If at all possible, I run plastic air brake hose, one piece, from the tank side of the relay to the button, this is the only hose that has pressure at all times and a leak is a problem, the rest only have pressure when cranking so a small amount of leakage is no big deal. Making it one piece with as few fitting as possible. Mine would go 4-5 weeks and still have enough in the tank to crank.

[yarnall]

I’d say you find more door parts to the L model and restore the parts H model next.
