    53 Differential Fill Plug

    I positioned the bolt with a hole through the center near the top of the differential rear cover near the top and well to the side of the ring gear. I never found any gear lube leaking out of the bolt head. So I think it is simple and functional. I think the hole through the the threads of my old fill plug was to vent the rear while draining the lube. Joe
  2. As described above, coil polarity is very important. A friend has a beautifully restored 1940 Ford convertible that had driveability problems under load. On these cars they often replaced the original coil including the mounting position. This is a positive ground 6 volt system. I checked the coil wiring and found that it was incorrect. Once we changed the wiring to the correct polarity the problem disappeared. Joe, BCA 33493

    Dynaflow question

    The transmission codes chart above has at least one error. I believe the torque ratio of the 1953 torque converter is 2.45 instead of 2.25 because the 53 cars had the first twin turbine simplified torque converter. Joe, BCA 33493

    53 Differential Fill Plug

    Packick: Your response sounds plausible. I use an aluminum bolt with a hole drilled through the center near the top of the back cover to use as a vent in case of a buildup of pressure. I am still not sure about the reason for the hole through the threads.

    53 Differential Fill Plug

    The drain plug is the very bottom bolt holding the back cover to the differential housing. Maybe the hole is there to slowly drain out lubricant if differential is overfilled? Joe

    53 Differential Fill Plug

    I removed the differential fill plug from my 53 Special to replace it with a better one (obtained from MrEarl) as the outside square points were butchered by previous owners even thought the car has only 66xxx miles on it as verified from the title document. The replacement plug came from a 1954 Buick and is solid steel. The original plug is hollow inside and has a hole through the threaded side near the head. Anybody know why the hole in the threaded side? I will try to attach a few photos. Joe

    Rear differential parts source

    I know Buick used 4.45 rear ratios on many models from 1930's to at least 1948 or maybe to early 1950's. I could never find anyone who could confirm my suspicion that Buick did this because they did not have an automatic until 1948, and then only on the Roadmasters. Now Olds got the Hydramatic in 1940 and Cadillac in 1941, several years before Buick got the Dynaflow. To minimize the need to shift gears in most local driving, the high torque Buick straight eights with the 4.45 rear ends could get around town with minimal shifting of gears thereby compensating, at least a little, for the lack of an automatic that required no shifting. Just my suspicion, based on trying to understand why the 4.45 ratio was used. I wonder if there are any old timers that worked at Buick who could offer their input on this. Joe, BCA 33493

    1948 Buick super rear shocks

    Apple Hydraulics in Calverton Long Island NY is a major rebuilder of these shocks. I do not know of any source for new ones. Apple is reputable. I believe there is a rebuilder on the West coast as well. Will be cheaper if you have rebuildable cores. Manager of Apple told me that they rebuild more front shocks for 1940 to 1950’s Buick’s than any other shock. Joe, BCA 33493

    1948 Buick Super Vacuum pump question.

    On both my 53 and 48 Special, the intake manifold vacuum pipe goes from the intake manifold to the vacuum section on the fuel pump, and then a pipe goes from the other fitting on the vacuum pump to the firewall, thence to the wiper switch and then to the wiper motor. The vacuum pump section on the fuel pump acts as a kind of booster when the engine vacuum is low such as when going up a hill. Joe, BCA 33493

    1940 Ford temperature sensor diagram

    Many thanks for directing me to this site. This is a very complete description of these sytems. Joe
  11. I am trying to help out a friend who has a 1940 Deluxe V-8 Ford. The wiring diagrams show a very odd arrangement for the temperature, oil pressure and one other sensor. They include a resistor and what looks like the symbol for a bi-metallic switch with a heater wire around the bi-metallic section. I cannot understand how this works and I have seen two different versions of the sensor wiring diagram. Does anyone on this forum know the theory of how this type of sensor wroks? Thanks. Joe

    Oil for Power Brake Vacuum Pump

    The latest Buick Bugle has an article on the correct oil for the Power Brake Vacuum Pump as installed in 1954 Buicks with power brakes. I was reading through the 1953 Buick Product Service Bulletin and noticed that this pump was being installed on all Series 50 and 70 cars beginning in October of 1953. In the write-up they state that the oil must be checked every 5,000 miles and if needed, add regular 5W oil. Joe, BCA 33493

    Third Brake Light

    Check the February 2018 Buick Bugle and in it I described a wireless high brake light that you can make yourself. Wireless because I did not want to drill any holes in the back package shelf. If that is not an issue for you then you can wire it directly as described above. Joe, BCA 33493

    Could possibly be pinion bearings that typically whine on acceleration but quiet down on coast. Please check back and let us know what develops. Joe

    1951 Buick Special - History

    I thought the 1951-53 Specials used the B body and the Supers and Roadmasters used the GM C body? Joe
