Twin H air cleaners

SuperDave

A while back, I was communicating with Nick or Dave S, The subject of 54's and air cleaners came up. I recalled that I had done a fix up of a September 54 Hornet Hollywood that seemed mostly unmolested. It had twin H that I am very sure was original to the car. The air cleaners were the type I have always associated with the 55-56 cars. The portion that clamps to the carburetor air horn is rounded as oposed to the squared off type, and the units have "American Motors" Decals on them as well as the "Twin H Power" decals. I changed them out to the more traditional step down air cleaners:rolleyes, but in hindsight, perhaps I should have left them alone. I wonder when the factory actually changed to the "new and improved" air filters? anyone know for sure? The car also had front seat safety belts with "AMC" labels sewn on. I am sure that was a dealer add on, but when?

Inquiring minds need to know..:rolleyes:

Nash introduced seat belts in 1949 as optional equipment, followed by Cadillac and Packard. Most automakers offered seat belts as optional equipment through the 1950s, but are seldom seen. Some were factory installs, and some were dealer added. Seat belts were not considered the "in"-thing then, as we know.



Wisconsin was the first state to require front seat belts, in 1962. Federal law mandated seat belts in all cars starting with the 1966 model year.

Dave, I had a 54 Hornet that also had the Rounded carb-bonnetts for the T.H.P that I owned many years back and it came from the orig.owner with them on it.

Could have been in the late 54 Hornets when they changed the style ?

We were Drag Racing the 54 at that time and discovered that with the New-Style Air Silancers (55) that with wide open runs you could not hear the air being sucked through the air filters like we could when running with the early flat-style.

We then removed the Paper filters and found that A.M.C. had formed the New-Styles with a Cone in the center that blocked half of the filter Intake air.

This cut down on the intake noise when carbs were fully open but, it also caused a decrese in air flow to the Carbs. (i think)

If you look at the 55 and the early style you will see the CONE that could block some of the air-flow.

Thanks Rudy

when I look at pictures of you guys' cars, the twin h air cleaners seem to be the ones with a screen on the end of them. I have a 54 hornet with twin h and the air cleaners are an oil bath type so obviously there were two types...why would that be...some kind of option?

SuperDave

Jim,

Yes the oil bath cleaners were an option. There may be some problems with having the oil bath cleaners on the short wheelbase cars and maybe some interference with the other engine accessories, such as power steering and oil filters? I'm just guessing because the only car I had with the twin oil bath filters was a 51 Hornet with out power steering or oil filter.They are really impressive!

The oil bath aircleaners were an option for the rural areas. Back in the day of the Hudson there were a lot of dirt roads. The oil bath air cleaners are far superior to paper elements.

I have the Twin-H dry cleaners. Was there another decal on the cleaners besides the "twin-H" decale? If so, where can I get a set?

The oil bath fliters were an option in all areas. The standard filter was metal mesh that was to be cleaned and oiled. There ware no paper filters untill later years.

I've seen what appears to be some sort of maintenance instructions on some Twin-H filters. I've asked Dany at K-gap about them. He doesn't have them or even know about them. Hopefully, someone on the forum may know about them.

SuperDave

I think both series of the "dry" filters had cleaning instructions. Only the AM versions had the larger American Motors decal. I have a picture of one if someone will post it. Send me an email at HETdwad1939@earthlink.net drop the het and I'll send it. I talked with Kale a year or so about them but we both agreed that the AMC decal would not be a big seller. Remember this venture has to make a few bucks to be worth the effort. I tried to find a suitable "service" decal from other automobile manufacturers but came up empty handed. All seemed to reference "Buick"or what ever car they came from. Also the second series filter had a part number sticker with the word "Hudson" on the portion over the carb. Again I have a picture of that one too.

Interesting stuff..Thanks for all the input.

The oil bath cleaners have a large AC Brand decal explaining maintenance. It's on the Pot portion. I don't have a piture of that one, but can shoot one if anyone is interested. I can't help but think that, that decal should be available from some other auto that used AC oil bath Air Cleaners.



If anyone is interested, I posted some air filter pictures on the MSN site under Dave Waddells Hudson pictures.

Talk to HET and forum member Silverone he has reproduced this decal. I think you can get them from him.

I've seen pictures of maintenance instructions on both styles of filter. The ones I've seen have been on cars for sale on ebay. However, nothing appears in factory photos I have or in my shop manual, at least as far as the smaller filters are concerned. Maybe someone with original air filters can post pics.

SuperDave

I posted some pictures on the MSN site. These are pictures of original parts. I will try to get one of the original oil bath twin H instructions posted today.

Fantastic! Thank you.

This attachment is the decal that was on the backside (and not easily seen) of my Twin H air cleaners. My '54 had 21,000 miles on it when I purchased it, and the air cleaners were original. The "Twin H" in yellow on the front side was painted on and did not have the circle around it like the common reproduction decals. This decal is a reproduction decal that I have created.

SuperDave

Super Six,

Great reproduction! The first picture I posted has that decal on it. I can't take credit for the picture, obviously someone from Mass. took the picture and posted it.. I hijacked it for my collection. I would like to buy a few sets if you are selling them. By the way, I just posted a poor picture of the Oil bath instructions. it looks like it was silk screened on the filters. Probably the same paint system that was used on your 54?



Some how we need to find a central depository for these original details. There are going to be many restorers after we are gone, that will want to know these little details. Any ideas in how we can start a data base?

Is there a decal for the dry type filters too?

The decal is for the dry type filter. I don't know if the oil bath had these or not but I would think that the filter element would be different.

Unknown

Are you sure? I see no felt in my original filters, only a wire gauze. Is "oftener" a Hudsonism?

RonS

I believe that the wire mesh filter screens work like modern K-N filters ie, clean then oil lightly. I found that Champ AF 101 or Wix 42110 are a perfect fit for the dry cannister type paper element. Rambler, Larks, and Hawks used these in the late 50s and early 60s.Ron

Napa 2110 also will fit the dry canister type. Super-Six did you print the decals on regular avery label stock or on some more durable stock?

I'm using paper filters on my car too. I've just seen a AC filter decal for a Buick. The "oftener" term is obviously an "ACism." If Huson had the decals printed, I'm sure the words "more often" would have been used.
