Hudson 1923 Transmission

in Hudson 1916 - 1929

Looking for a rebuilt 1923 Hudson super 6 transmission. Was having a clutch issue and after a rebuilt clutch still having the issue 10min into driving. Wildrick did the rebuild and now says it may be the play in the transmission. I see about 1/8 inch movement. Trying to find a new rebuilt transmission. Does anyone know what other models might fit my 1923? Maybe there is a 4 speed out there? Did any of the later cars have interchangeable transmissions with the 1923? But most of all do you think the play in the shaft allows the clutch to bottom out against the flywheel making it unable to shift?

    1/8" is too much, but I doubt it would have any effect on the clutch. It is adjustable by shims on the rear shaft. of the transmission.

    Find a 1929 flywheel and all the parts to the 1929 gearbox. You will then have only 1 clutch plate.

    Will the 1929 flywheel fit the back of my motor without any modifications? You are saying it only had one cork disc? How will the rest of the transmission fit with my current starter pedal etc.?

    You can transplant a complete 1929 flywheel, clutch, and transmission, including throw-out bearing. Use your existing pedals. 1927 and '28 will fit also.

    Is there an advantage to use the 1927-1929 flywheel , clutch and transmission? Was there a different gear ratio in these transmission compared to the 1923?

    The gear ratios are the same. Main benefit is simplicity of single plate clutch.

    You may give us your location if someone has 1929 trans parts. I may have an early trans - not looked at -but inside storage - heavy. Have not identified it. Gert

    Thanks Gert,

    I am in Louisiana near New Orleans. Just heard back from Wildrick. They found a 1923 transmission and are going through it to make sure it is working. Said it is doesn't have many miles on it. Not sure how they can tell but keep me in mind if you find that 1929.

    Robert. The multi plate clutch is like silk when set up correctly. It will out last you by a long shot.

    Does anyone know if any local transmission guy can rebuilt the Hudson Transmission. It should be easier than an automatic. Has anyone ever done this? What questions should I ask? Are there parts that I may not be able to get? Any ideas would be helpful.

    You won't be able to get anything! Hyatt roller bearings are no longer obtainable except from specialist obsolete parts suppliers. It's usuallly "Pik'n'mix" if you have several transmissions, find the best you can and use what you have.

    The problem is my transmission and clutch work for 10min and after that can't shift. If someone takes my transmission apart what would they be looking for that would cause this problem?

    Just got on line and found a lot of info on Hyatt roller bearings. Looks like the company was bought out in 2012 by SKF. Lots of listings for the Hyatt bearings. What number or name of the bearings that we need for the Hudson transmission? Is there a list somewhere with the breakdown so I can buy the bearings and have them ready for the transmission guy?

    Looks like I have to take part of the Transmission apart to replace or add shims to reduce the movement of the shaft. Since my transmission was filled with a heavy grease, will I be able to see the drain holes inside to see if they are clogged with grease? This may be the reason after 10min I have trouble shifting if the lubricate is not getting to the gears through the drain holes in the transmission. Anybody any thoughts and suggestions?

    If you have heavy grease in the box, remove all of it and put in the proper oil.

    Robert , on other sites you asked what oil you used and you said 600 wt this is correct for your trans.

  • barrysweet52

    In the 1920s 600W oil type and category I believe is not available today. I believe nothing less than 140W oil is reqd in the gearboxes now.

  • paulrhd29nz

    140 is way to light. 600 is really evadible at Restoration Supply

  • rhurst

    Yes Paul that is what I used but Geoff thinks I should go even lighter 80-140. I'm worried that the heavy grease has filled the lubrication holes inside the gears and transmission not allowing the gears to be lubricated. That could be my problem with it heating up after 10 min of use and not allowing me to shift.
