VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 1933 chev "Auto Jack"

Does anyone out there know if the 1933 Chevrolet came with a "Car Jack" or was it an accessory?? If it was standard, was there a makers name on it??? I see a lot off antique auto jacks on eBay but don't know which one to buy!

Your '33 did indeed come with a jack and handle. Jacks are not well documented in Chevrolet literature so verification is difficult. At least some early '33s came with the same jack as the 30-32s. The jack in later '33s is still subject to debate.

The jack is a S C R E W type rather than a ratcheting type I believe.The handle should fold in half also......This describes many jacks made years ago ....Is the use of the jack shown in the owners manual?There may be a picture there that will help a little.

In "Instructions for the Operations and Care of CHEVEROLET MOTOR CARS" Eagle series CA published June 1933 on page 62 has two pictures, and on both off them the jack is behind the tire and you only see part off it, but the worst part is that both jacks are different....figure that one out!!

Often previous years pictures or drawings were used.....Also jacks were made by different suppliers so all 1933s did not have the same exact jack-although type would have been the same.

Two questions, first being is my photo the correct jack for the 1933 Chevrolet. I rarely see them show up on eBay so I'm in the dark here. A few years ago the same jack pictured was on eBay and was being sold as a 30-33 Chevrolet jack. The top part on the pictured jack measures 2" x 2 3/8"

Second question who made the jack and can one find any constistent identification numbers stamped on the factory supplied jack ? 33chev states that on page 62 there are two different jacks pictured... wow... can someone send me a visual ?

Mr Olsen notes there is a jack shown in the 1933 owners manual. He also calls it a varient ( does this mean there's others ? ) The jack he is talking about is noted to have a top that measures about 3/4" x 3" ( these measurements do not jive with my pictured example's measurements )

I have this type when I bought my 1936. I am the third owner. I also have this type in the 1936 truck. I am the second owner. I have also seen other styles of jacks in these same vehicles. There were indeed different suppliers of jacks to the Chevy cars and trucks.

Randy,
I have one of those jacks that has a top pad that is approx. 1 1/4" by 1 1/8". My research many years ago gave me the impression that the earliest 1933 jack was the same as used in 1930-32. Not sure what replaced it in 1933 model year production. My understanding is also that the tools, jacks, hub caps and maybe other small items were not put into the cars at assembly. Some were shipped in separate boxes and others put in by dealers from bulk stock just prior to delivery to the customer.

We must remember that the illustrations and photographs in many Chevrolet publications are not 100% accurate for the year referenced. As Gene correctly pointed out earlier publications with their illustrations and photographs were not always updated in later year material. Also in many cases the photos were staged and enhanced for publicity and promotion. I understand that often those are the best references that are available.

While this may not add insight to what is proper for a 33 jack, it might help reinforce the point about separate boxes put in by dealers from bulk stock. My 34 Master has what I believe are all of the original tools under the front seat including remnants of the original box they came in.

The 1934 Master (only) had a special jack. It was a double screw jack that had a very high lift due to having to br placed under the front cross member. The outer screw is very large and the inner a "normal" size.....and was painted green, I have factory pictures of it. Also it as a heavy iron body.
The jack pictures looks like the factory jack that came with light trucks in the late '40's-early '50's.

Thanks for the information Gene. I’ll start a new topic to discuss the green jack so we can search in the future.

Chipper…
I have 3 different but similar jacks for the 31-32 Chevy here on my display shelf. After the holidays I'll post pics of them, they are extremely identical but with small difference. The 1930 Model A Ford ( rare jack ) used a very similar jack too. Small differences but like they say the devil is in the details. I've read that the early 33 Chevy shared same jack with 30-32.

Minetto…
Your box is a real treasure. I've been collecting NOS photos of jacks from the 60's and 70's as they are still around, and your 1930's really is super cool. Your jack pictured matches my references as a 34 Master.

Sure would like to nail down the ID for the 1933 jack. Time to start popping some trunks and looking under the seats and making a comparison. And let me add photo ID is a must… what may seem as the same to one person may really be different to the trained eye as there's like 50 manufactures of old jacks and a zillion different styles from each factory.

Randy,
I will have to check my collection tomorrow. There are at least 4 and I am thinking maybe several more correct jacks for the 1930-early 1933 passenger and 1/2 ton trucks.

The parts book is not always a good sorce for jack information. Often an earlier jack would be discontinued and combined with a later jack.
The 1935 parts book shows one jack, part nember 364914, for 1929-1935 cars exceppt 1934 Master and 1935 Master Deluxe.
as an example. It does list a jack handle for with a square end for 1930 and 1931 and a handle with a hook end for 1930-1933 so two different jacks may have been used.
The 1934 and 1935 Standards both used an axle type screw jack. The 1935 and 1936 Master Deluxe AND 1936 Standard had a screw type bumper jack and had special brackets on the rear bumper bracket attaching bolt that served as a place for the jack attachment.

Pop some popcorn... this is my 18 year collection of early 1930's Chevy jacks and photos. The photo on the far left is a very rare early 1930's Ford jack, matter of fact someone just sold such a jack on eBay and had it listed for 1930-1933 Chevrolet. So either a Ford collector got a super deal on a jack for $40 or there's a Chevrolet owner who will be displaying the wrong jack come this summer.

The three jacks on the right are probably 30-33 Chevrolet jacks... tell me one way or the other. The big note here is that of the triple set the jack on the left uses a square jack handle tip, and the two to the right uses the more common oval tang tip jack handle. All three jacks the center bodies are all different in construction. All three are about the same height. The oval vs square jack handle could be merely a supplier preference..? ( Noted in quotes are what is found etched into the top horizontal gear )

I have an AS-51 jack and one same as your 4K although it is marked 4H with a "W" on the opposite side. They are as you describe one round top and the other a flat top. One is tang drive (4H) and one square drive (AS- 51). The top swivel plates are also different, 4H being 1-3/8" and the AS-51 1-5/8". I did note that the top gears on both are the same diameter-2-3/4". I got the AS-51 at an auto flea market and the seller thought it fit a 70's Toyota pick up. With the handle it cost me all of $2.00.

I have looked at most of my jacks from the 1930-33 period. I have about 20 but didn't count to be sure. Been collecting them for too many years. I have taken a couple of pictures of five different jacks, both from what I call the front side and another in the same order from the back. From left to right the top gears have AS 51, W, W, S101, AS 51 stamped or cast into the top surface. Some have another number which I consider to be quality control (mold) numbers. It may be hard to see but the one on the left and one in the middle have the slot and the other three square handle holes. There are also differences in the construction. The one on the left is crimped, next two have two rivets on the "front" side and three opposite, the two on the right have three rivets on that side and four opposite. There are also differences in the base, main gear side profile and top saddle. Four have a five pointed saddle and the next to the right a rectangular one. As a note: I have not found a crimped jack with a square hole. Most others have either a square or slot. With both square and hooked end handles shown in the February 1930 parts book I am sure that both versions were available. As a side note: the hooked end handle when in the slot will allow pulling the jack from under the axle. The square does not!

My understanding is that there were at least three different suppliers during that period. My memory is that AS was probably Auto Specialty, W = Walker and don't remember what "S" might have been. Need to find some of my notes. Didn't come to the surface in my last search. Ajax and Noblitt-Sparks made jacks for Model A's in that period.

It should be noted that the Model A jacks from the early 30s are very similar to the Chevrolets. I suspect some likely were made by the same companies. I do have a few that definitely are Model A and not Chevrolet. I had in the past been of the opinion that all the jacks with the 3 & 4 rivets were Model A but am not sure any more. They might have been supplied to both manufacturers.

Let the fun continue.

I'm liking the replies, and Chipper I'm really liking the scenic backgrounds...! Note that all the Chevy jacks the top gear has a 45 degree tilt around the edge of the horizontal gear. On the Ford the horizontal gear is a 90 degree angle of the teeth at the sides.

Time for the 1933 owners to sound off and let us know what's in their trunks and under the back seat...!

I didn't mean to have the background detract from the subject at hand. It was the first location I found and the sun cooperated lighting the jacks. The shadow makes discerning the slotted vs square holes a bit challenging.

It should be noted that there were at least three jack manufacturers in the 1930 to 1933 (early only?). That is typical of GM part supplier policy. It should also be noted that there were at least two different handle types in addition to the hook and square ends. If I can remember to take representative photos I will post them tomorrow. What? a Christmas present?

My 1933 Master has the same jack as the one on the far right with the oval slot. My 1935 Standard had the same jack again with the wrap around construction (as opposed riveted ) but with the square hole. These jacks fit neatly under the front axle when the tyre is inflated so in the case of a flat you would be jacking on the spring, There is also a smaller version of this jack which is
about 5" tall which would be more suitable in case of a flat.

It never made sense to me why the jacks wouldn't fit under the axle with a flat tire. As pointed out it is necessary to put it under the spring next to the axle. Since the spring at that place is basically horizontal it is not likely to slip. Given that it butts us against the axle reduces the movement in that direction. So first impression may not be always correct.

The previous screw jack I bought for my 33 Master was obviously the wrong jack. So yesterday I bought another from Ebay that might not be completely correct, but I am sure it will fit the car. I only paid $9.00 plus shipping so I'm not out much money for it. Now I just need to find a handle that fits the jack.

Here is a picture of the one I just purchased.

I saw that Jack on E-bay. It looks like a 34 Master but is too short. Not like the 33 Master.

Jonjet………….The ratchet jack I bought last week turned out to be way too tall to even fit under the frame of the car if it has a flat tire. I'm hoping this jack will fit under the springs with a flat. It should be here by Wednesday so I'll know at that time. At $9.50 I'm not too worried about it.
