VCCA Home Forums TECHNICAL - 1945 AND NEWER 1946-1948 bumper jack

I think Iam looking for a bumper jack. The car is a 47 chevy. Does anyone know a good place to see the correct one for my year and make of car?

1947 Bumper Jack. I have access to a 1948 ratchet bumper jack. Anyone out there in Chevyland know if the 1948 Chevy passenger car jack is the same as the 1947 jack?
If it is, I can send you some digital pictures of the 1948 jack.

Bumper jack part number 609656 is listed in the 1946, 1947, 1948 and 1949 parts books with the application of 1934-1948, ALL PASS. A different part number is listed for 1949. Earlier books do not contain the 609656 part number. Therefore the conclusion is that 1946, 47, 48 used the same jack. As in other years it is likely that more than one manufacturer made Chevy jacks so small differences are likely.

The above conclusion is reasonable as there were very few differences between the three years.

Mark, if you are a VCCA member you can check with the VCCA tool advisor. Oops that was the advisor. Guess we need to add to his library. Sorry Dave the

Hey Chipper Dipper. You might want to clarify which "Ray" you are referring too for those that don't know who the tool dudes are.

You think the old mechanic would be confused with Ray "the master"? :eek: The VCCA members who check the tech advisor page will know it is not Mr. Holland but Mr. Lemasters. Those who are not members are not priveged to be able to contact a TA. :rolleyes:

I was thinking of the newer VCCA members that are not familiar with who is who yet, therefore it would be easy to get the two Ray's confused until the newer members learn who they are.

1946, 1947 and 1948 Chevrolet bumper jacks all appear to be the same item if we just look at the Chevrolet Master Parts Price List/Catalogs for the years 1946,47 and 48. The number listed for the "Bumper Type" jack is Group # 8.820 and Part # 609656. One of the problems is that a manufacturing improvement can be made by Chevrolet on an item like a bumper jack and Chevrolet would be justified in keeping the same number in the Parts Books. Therefore, rather than myself "assuming" that all 3 of those years are absolutely identical, I am still searching for difinitive documentation. For now, it is reasonable to go with the alleged fact that all 3 years are the same. As more information becomes available, we will add to our knowledge base. Once I publish on my website that all 3 years are the same, if I have made a mistake, it sometimes takes years to undue the damage, with VCCA people buying/showing/ and ultimately having the wrong jack judged at VCCA meets.

It's not just the bumper jacks.... Any part, repeat, any part listed as current in a Chevy (or any) parts book is just what they had available to sell when they compiled that book. It does not imply that the part they had available on that day was the same as the car was built or supplied with! I don't know how to say it any clearer... BTW, this is not particularly a Chevy fact, it is just a fact of life.

Toolman, I understand your dilemma! Some folks want the final definitive word, and the Chevy folks didn't always leave a clear trail.

It is a well-known fact that GM had at least two suppliers or plants for every part. Typically GM controls one and another is an outside supplier. That policy has been in place for many many years. Because of different manufacturing processes, different equipment, different interpretation of the specifications and drawings the parts from each plant or supplier are different. Then there were the differences due to manufacturing equipment wear and repair, improvements (product or cost) introduced during production (or a contract). Then changes from one supplier to another because of work outages, end of contract, etc.

All that said, are there differences in jacks supplied for 1946 to 1948 Chevrolets? You bet there are! Are they sufficient to change the part number listed in the parts book? Apparently not.

The small differences in the parts that result from the above need to be an accepted part of the VCCA judging and evaluation process.

Now for jacks and tools. Normally individual tool sets, jacks, starting cranks were supplied in bulk to dealers not packaged for or enclosed in each vehicle. It was the duty of the dealer to put the tools and jack in each vehicle delivered. If you want documentation get a copy of the "Double Check" filmstrip from 1930. It is all about making sure that the dealer put the tools in each vehicle. So are the tools that were placed or are found in each vehicle absolutely correct? Maybe not!

Confused? Me too. Just means we need to be tolerant of the process used by Chevrolet and GM and their dealers and suppliers.

How bloody convenient that this is the active topic. I came in to ask if this was the correct jack for my 48 Stylemaster.. :)

Not sure if its a correct jack.--reason--The Chevrolet jacks used a round rod -or- the lug wrench for a handle.Picture of jack looks as if the handle receptical is flat and would require a flat bar type handle.Also 1948 jack post was not centered in base-but was off set.Pictured jack looks to be centered in base.

I have seen this jack on later Chevrolets (51,thru 53) at one time or another, the receptacal appears to be a round hole with the metal molded down and around to reinforce the peice. I have one that looks the same and I took it out of a 51 hard top and the same jack was with my 53, I never bought either car new but the jack appears to fit very well. I have seen several in older Chevrolets that did not have the pressed steel shaft but was a solid round rod.

Yes, the jack looks more like a 1949-54 jack.Also looks as if it could be the UNIVERSAL jack listed in the parts book.This was a different jack than the one that was included with the car from the factory.The factory jacks did have a pressed steel square center shaft from 1936 (late style) and up.However they did sell a friction jack with a round shaft thru parts as well as a hydralic bumper jack.

Jacks from 1936-39 were designed to lift from the bumper brackets and the 1940 and up hooked under the bumper bar itself.Same base was used 1940-48 also used a seperate round handle to operate rather than the lug wrench

Looks like the lug wrench(handle)is not included in this deal..chef
