The amazing things you can find at a Neighborhood yard sale

OK OK you guys will love this, I went to a yard sale or neighbor hood type flea market and sitting in a box was a 12V air pump type motor...LOL Of course the insane ideas came rushing to my head when I saw the pump and I just had to buy it, cost??? $5.00

The machine itslef was set up as a battery connected clamping device. But it's a well made motor, not a cheap one and I knew the possibility of keeping air wipers on the M151-LC is now a reality...LOL

Keeping the air wipers also keeps the M152-LC that much closer to stock, the new Nissan engine a air pump or any ports to mount one like the original M151 Hurricane engine did for the air pumping pressure and so their are few options on trying to figure out how to tap into a costant air flow out side of the exaust manifold and since the exaust is a real bad idea to tap into I liked this idea much better...LOL so a external air pump will be required but at least the Jeep will still have air wipers which to Nate and I was just wicked cool...LOL

All I will need to do is set up new wiper hoses and hard wire and mount the motor under the dash with a 2 speed toggle switch, as for the pump itself out of sight out of mind right???...LOL... I have a small bleeder valve so pressure circulation will not be a problem...LOL

I always liked the air wiper set up better and this little motor has some power so after hooking up a secondary speed switch I am pretty sure I can get the whole thing to work...LOL This saves the search and money for the 12V electric Jeep wipers I was looking around for too.

I hate those type of wipers anyway and was dreading having to buy them and then install them.

Been awhile since a instant wow look what I found, and what insane thing I can do with it is that I found, has happened to Nate Micki and I so it was like old fashioned magic...LOL Any suggestions of the best rubber hose lines???

I have a nice set of M151 wipers motors but no outer wiper arms with the blades. Anyone have a set of M151 wiper arms with blades for sale or trade???

Well, I am not an expert on A1s as I have an A2. But so far I believed we talk about a vacuum pump for operating the wipers. you are talking about getting pressured air. Wipers used to be hooked up to the intake manifold for that reason (not on the 151 of course)...

M151-LC · Unread post by **M151-LC** » January 5th, 2008, 12:32 pm

I did consider that option with the intake along with the insane notion of the exaust as well, but it comes down to space of the engine compartment and to be honset my real lack of intimate knowledge of Japanese engines...LOL

I mean the fundementls are all the same, but many aspects of this engine design I am not very knowlegable about.

This entire power pack is so different from a Hurricane, like night and day, I am glad it will all be a 12V system and the fuel injection will be a added bonus.

I only wish I could have installed a larger engine, like a 258 or 4.0, but they are just to large to fit in the engine compartment without modifying the fenders, something I was not going to do. Then the transmission size was just to long and wide to fit in the tranny tunnel, without having to modify the uni-frame, and their was no way I was going to cut into a non demil M151 uni-frame...LOL

It's so much easier to modify a Willys Jeep, you can fit a larger power pack in them with ease, and then their are milloins of after market parts at your command, the M151 hardly have any after market parts beyond stock.

To be honest if I was ever build another one of these rigs I would buy a brand new uni-body from American Growler and just go from their, I think it could be a very popular item to 4x4 clubs once they see ours in action. `

Since your making a replica of the original M151-LC why not get an A2 windshield and A2 electic wippers? Wouldn't that look more like the original prototype and make life a bit more ezer?

Bleddyn,

You always call the 151 engine a Hurricane. Why? Isn't the Hurricane engine the Jeep engine with the overhead valves. I do not see any connection to the 151.

Yeah, I thought the "hurricane" replaced the "go devil."

Back in the early to mid 1970's when I was a young Tech everyone reffered to the M151 engine as a Hurricane. The refference is kind of the same way the M151 was reffered as a Jeep I suppose, The M151 was anything but a Jeep, yet back in the day we called them Jeeps all the same. I stopped calling them Jeeps as I saw how many people in modern times called them MUTTS!

To me on a personal level a M151 will always be a Jeep. Anyway, If everyone wants I can call the engine by it's TM stock name the L142 I will.

OK as far as the A2 windshield frame is concerned I was going to go that way and have a bunch of A2 windshield frames, it came down to trying to find away to get the 24V wiper to work where everything else was going to be a 12V sysytm.

To be honest, I am no electrician, and was not sure if I could find another motor or een parts to convert the motor, so instead of tering my hairs out over the whole thing, I opted to use the air wipers, if it don't work out as good as I hope it will, then heck I was only out $5.00 on the pump...LOL

I did find a New set of after market wipers on line made by Chin Lang AutoParts Co LTD, these 12V electric wipers work great, they are cheap to purchase and I have a few sets on our 1954 M38A1 Rock Crawler and Nate's old green 1950 CJ3A.

I thought i would try and be creative with the new air pump first and see how it all worked out.

You can call the engine what every name pleases you. I just think Hurricane is wrong. That's the name for the Willys engine with a mixture of overhead and vertical valves. Maybe you called them Hercules engines.

Concerning the wipers others already have commented too that you want vacuum, not pressurized air. There are actually 12V vacuum pumps available, some cars had the to support the brake booster function if you had a big V8 with aggressive cams and as such low vacuum at idle. They can be found in scrap yards, but of course getting more difficult these days.

Its not Huricane it's a Hurculies (SP?). Made by Hurculies motors in Canton Ohio.

you will find no reference to the 151 engine but it shows a picture which I would identify as a 151 engine...

The first engine used in the M151 was the Ford L142 which was an Ordinance / Continental with downdraft card that produced 71bhp.

The second engine used was the Hercules (the one you most likely have) 151.5 cubic inches with side-draft carb putting out a mere 55bhp.

Horst · Unread post by **Horst** » January 7th, 2008, 3:33 pm

Spike,

I have seen this info a couple of times on some websites. But who has actually ever seen this engine with the downdraft carb. Sure it is not an urban legend ?

Spike · Unread post by **Spike** » January 7th, 2008, 3:48 pm

Not an urban legend. I'll try and find a picture for you when I have a little more time to search.

Check out this link.

I don't doubt two manufacturers. But search the web a little bit and you see that people copy all type of wrong information. The AM General sales leaflet advertises 71HP, so I don't think the 55 are correct. And I don't think the downdraft carb info is correct. But, well, I always accept learning...

Interesting thoughts, Horst. You're right "facts" just get repeated over and over.

If you look at the 'Hercules', website that you post a link for, it lists the L141 as having 65bhp@3500rpm. I've looked through four TM's for that data.

Maybe someone out there knows a path to some known accurate information regarding this engine.
