  • clam shell leaking

    universal clam shell was leaking badly so replaced the felts. thought the problem was solved but after several hundred miles it is leaking badly again.have been using cornhead grease. should I try a thicker grease
    or any ideas why this is leaking again. 1931 deluxe delivery.

    I have had good results with the paper gaskets and the red grease. I don't remember which kind, but know it was red.

    It is not unusual to leak, but try assembling the 2 halves first before assembling to trans.
    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

      not sure how you would do that

        We had the same issue after pumping the corn head stuff in the universal with new felts, etc.This grease appears to become less viscous as it warms up.
        The speedo gear seems to like it though. Perhaps the felts are too soft when compressed.

          Welcome to the VFF!!

          I fill the empty cavity with a 14.5 ounce grease tube using my air grease gun. The same grease i use for my wheel bearings and chassis
          I would try switching products

            took off the speedo housing off and the cornhead grease started running out like it was oil. pumped it full of mystic jt6-2. hopefully this will take care of the problem.

              I may remove the cornhead as well. It is a Polyurea based grease. However, I believe the Mystic 2 grease is lithium based and not sure that should be mixed up with non compatible products without a thorough cleaning process.. We have old non- lithium based tube grease which may be more compatible. Any thoughts if this really matters?
              As a side note, not sure how cornhead works in freezing climates in steering boxes. We've tried it and it seems to be OK so far, except it can leak some when it heats up..

              Universal joint
              by carolinamudwalker
              I am having trouble keeping the grease in the universal joint. It is leaking out from the upper and lower clamp joint. Mostly on the left side. I installed the after market blue rubber "O" ring and it does not leak from there. Could I have an alignment problem between engine and rear end It is leaking out as fresh grease after driving a few miles....

              Clamshell ujoint grease issue
              by plyfor
              Per some suggestions, we packed corn head grease in the clamshell and find that when it gets warm , it drips some from the lower half even with new (felt) gaskets.
              Should we replace it with chassis grease ?...

              Where does the grease go?
              by carolinamudwalker
              When I put my transmission in I packed as much grease as I could into the universal joint. Then I pumped grease into the clam shell until it came out the speedometer cable turtle (bolt removed) I just greased the chassis again and the universal joint took forever to fill back up. I don't see evidence that it is leaking out so where does it go?

              U joint closure
              by Mickey
              Is there anything wrong with squirting this area full of grease before installing the engine and closing up the U joint? That would be followed by filling the U joint with a grease gun.

              Grease viscosity question.........
              by Grit Kid
              I use red and I noticed today being hot and sorts, I was looking for something and I open the door to a cabinet that has my grease guns. I notice the grease had leaked out onto the shelf. I guess this would be from being so hot and even hotter in a steel garage. If this is happening to the guns, what about Sarah's joints that take grease? Seems the viscosity is breaking down.

              Follow up question on greasing the U-Joint
              by Rob Doe
              Well, this is embarrassing. I'm crawling around under my coupe Everything is gloss black. It's dark under here. I've had my hands all over this clam shell and I don't see or feel the grease zerk. Where on the clam shell is the darned thing. I expected it to be on top somewhere.

              I know I've lost my sense of smell. Probably TIG welding or spraying fungicides. Now its my sense of touch?...

              Corn head grease in differential??
              by wrndln
              I did a search on corn head grease, but only found topics about using it in the steering box and U joint cavity. I think the steering box usage would be great to stop leaking. I am not so sure about using it in the U joint cavity, but maybe it would work there. My question is about using it in the differential. It seems that many rear-ends have minor leaks around where the axle housings are bolted...

              Transmission rebuild
              by Dennis
              I'm doing a rebuild on a stock transmission and have the parts I felt needed replaced. So I have some questions regarding the bearings. Both of the new ball bearings have seals on both sides, basically complete sealed bearings. I can see the input shaft being ok with the seal on the front, but what about the rear? If the rear has seals, then how does oil get back there as it used to for the u-joint...

              Grease in speedometer
              by carolinamudwalker
              I searched the forum and checked the service bulletins but didn't find an answer. Did the cable end to the meter have some kind of felt washer to prevent the grease from entering the meter? Mitch set me straight about completely removing the turtle when greasing the UV joint. I had only pulled one bolt out and stopped when I saw grease at the bolt hole. Big glob of black grease obscuring the numbers...
