Hudson Rope Seal Question????

Does any one have a diagram on the installation of a rear rope seal on a 1949 Hudson 262 ? I plan on doing this while motor remains in car. The book I have is not real clear. I notice I have some wood strips that came with rope. Where do these come into play? A photo of this sure would be helpful. Would be thankful for any in put.

Thanks, Paul:confused:

    Call Dale Cooper at (513) 821-6200, he sells the seal kits and can tell you how to cut the rope seal to length. His kits come with guides to correctly measure the seal for proper cut length and a razor knife to do the job. As for the proceedure, follow the 48 - 52 factory shop manual (engine section).

    Use the shop manual if at all possible. However, there used to be a 'rear main seal' changing tool set pretty much available. I've never used one but the main piece of the set was a small spring steel piece with a corkscrew on the end of it to pull out the old main seal. I don't remember what the installation tool looked like though. The wood pieces go between the rear main bearing cap and the block for a tight oil seal.

    I agree to try to get ahold of the shop manual instructions. As far as the wood pieces and/or rope, from what (little) I know originally the factory sealed these with wood pieces only. Long ones vertically first, then short ones horizontally last.



    I've found that the replacement wood pieces pale in comparison with the original wood parts. I've got both on my bench, and you can see the replacements are best used for kindling for a really small fire. I use only the rope after saturating it with hi-temp RTV sealant. I use a long (about 4") small diameter flat faced punch to pack it up into the channels. It takes a little 'feel' but if you take your time, you'll get them filled correctly.



    I didn't realize there was a specification for the length of rope to start with. That would've come in handy in the past. Once I was in a hurry rebuilding (evidently), and failed to pack enough rope up in there before packing it off at the bottom. It felt right, like it was 'full', but later when I had to remove the crank for something else, I discovered I hadn't filled the cavities in a couple of places. It would have leaked like a sieve! So I measured out about 8-10 of rope and tied a knot there. Then I packed it in up to the know and I knew I had that much material in there. It must have worked, because they don't leak at all now.



    Good Luck,

    Doug

    The term "Rope" is a term used for the rear main seal itself and does have a length requirement, the cotton "Packing" to seal the front and rear main caps is another subject and proceedure. Doug you are correct about the install proceedure for the packing.
