Jolly_John Posted June 20, 2020 Share Posted June 20, 2020 One neat old specialty repair tool is never enough....right? So, I have two for you to choose from. They are both designed for the same purpose. These tools were created to save the mechanic's time, when needing to do transmission and clutch work on the 1939 BUICK. These specialty service tools eliminate the need to disassemble the torque tube, or remove the rear differential. The '39 rear end is mounted on coil springs. One end of these jacks mounts on the front of the differential housing, while the other anchors on the frame crossmember just behind the transmission. Operating the ratchet jack puts pressure on the rear end, and pivots it slightly backward, as the coil springs arch to the rear of the car. This slight rearward movement of the rear end and torque tube enables the front of the torque tube to be disconnected by the torque ball, and creates space for the tranny and clutch components to be removed. This tool is a great time saver. I heard about this '39 BUICK specialty service tool many years ago. But, never saw one, until I had the chance to buy both of these about ten years ago. Now, it's time to get one or both of these out into circulation. Take your choice of either of these tools. While each has slightly different design features, both perform the identical function. The one with the sideways crank by the rear end must be designed to keep the rear end and coil springs straight, as you exert the rearward force. At least that's my take on that one. Again, either one should do the work intended. Please PM me, if you have questions. The price for either is just $95, plus the FedEx Ground shipping. Pick-up in central Wisconsin is also possible. Thanks for looking. John 1 Link to comment Share on other sites More sharing options...
Jolly_John Posted June 21, 2020 Author Share Posted June 21, 2020 The first '39 BUICK rear end screw jack pictured has been SOLD. The second one is still available. Thanks. John Link to comment Share on other sites More sharing options...
1939_Buick Posted June 21, 2020 Share Posted June 21, 2020 Interesting tools, but too far way for me The first looks more engineered. The second more home made in style. 1 Link to comment Share on other sites More sharing options...
lancemb Posted June 21, 2020 Share Posted June 21, 2020 Some guys do the same thing on later years by using a come-along. Link to comment Share on other sites More sharing options...
Jolly_John Posted June 21, 2020 Author Share Posted June 21, 2020 (edited) I believe both tools are factory-made. Although the second one may be from an automotive aftermarket source, rather than Kent-Moore, the "official" BUICK service tool provider at that time.

Jolly_John Posted June 22, 2020 Author Share Posted June 22, 2020 Yes, Lance and Ben....I've heard of both those alternatives in my many years of messing around with 1939 Buicks...especially when the specialized screw jack service tool like I'm selling wasn't available.

NailheadBob Posted July 1, 2020 Share Posted July 1, 2020 John, I received my rear end axle jack today. WOW is all I can say, This is what I looked for to aid in transmission removal with a torque tube. Did you sell the other one? Thanks Bob Link to comment Share on other sites More sharing options...
Jolly_John Posted July 2, 2020 Author Share Posted July 2, 2020 Thanks for posting, Bob. I'm glad that you're happy with your purchase. Nothing like those Kent-Moore BUICK factory tools, is there? In response to your question....the second rear end jack is STILL AVAILABLE. It was a pleasure doing business with you, Bob. John Link to comment Share on other sites More sharing options...
NailheadBob Posted July 3, 2020 Share Posted July 3, 2020 (edited) I cleaned and painted my newly acquired rear end axle jack. It measures 26" when screwed all the way in, extends to 49" and weighs 25 lbs, and is ratcheting in the center where it is labeled Simplex, it is a Kent-Moore # J6741 KMO numbers/letters both on the base where it attaches to rear end.

Jolly_John Posted July 3, 2020 Author Share Posted July 3, 2020 Nice work, Bob. Your rear end jack looks super. Glad you're enjoying your purchase. John Link to comment Share on other sites More sharing options...
NailheadBob Posted July 4, 2020 Share Posted July 4, 2020 Here is a better picture, looks so good I don't want to get oil or grease on it when I remove my next transmission on a torque tube Buick. Bob Link to comment Share on other sites More sharing options...
Jolly_John Posted July 4, 2020 Author Share Posted July 4, 2020 That's also what I was thinking, Bob, but didn't want to say! John Link to comment Share on other sites More sharing options...
Jolly_John Posted July 17, 2020 Author Share Posted July 17, 2020 A quick update: The second rear end jack is STILL AVAILABLE. Makes transmission removal or clutch work much quicker, easier and safer on torque tube driveshaft Buicks and other cars. Jack #2 is a quality, factory-made tool.....NOT something put together by a d0-it-yourselfer. Just $95, plus the shipping. Thanks for looking again.

telriv Posted July 18, 2020 Share Posted July 18, 2020 I learned about the bumper jack trick in the early 60"s when I had my '55 Buick Special. Ended up having 13/ '55 Special's & Century's. Link to comment Share on other sites More sharing options...

Century Eight Posted August 7, 2020 Share Posted August 7, 2020 John Is your remaining Jack still available and do you think it would work on a 1950 Buick Super? Link to comment Share on other sites More sharing options...
Jolly_John Posted August 7, 2020 Author Share Posted August 7, 2020 (edited) Hi, David. I believe this jack would work on most any BUICK that has torque tube drive AND rear coil springs. However, this second jack was purchased a few days ago. I've been involved in a residential move for several weeks, and have been slow to post updates on the items I have for sale. Sorry about that.
