P15 Air Cleaner / Air Filter Gasket (Inner Filter Can to Element)

[tollertdi]

As many of you probably know, there is supposed to be a gasket inside the Filter Can that prevents filter oil from getting down into the carburetor.  There is no Chrysler part for this.  See below for picture of gasket location:

My original gasket was cracked and brittle, so I measured it and looked for a replacement.  I selected a gasket that was very close to the original in terms of the inner diameter which is the most critical for sealing.  Also, the selected gasket was 1/2 the necessary thickness, so I bought 2 gaskets and glued them together.  The part I selected is built for Tractors and is available from a number of sources on the Internet.  Part number is IHS2642  (Note: The first letter is an I not a 1 ONE).

 

Here are the dimensions of the part vs the original

 

                               IHS2642            Original

Inner diameter         1.87                     1.95

Outer diameter         2.6                      2.45

Thickness                 .18   (2)                  .18

 

Here is a picture for comparison:

When I rebuilt the carburetor a couple of months ago I got two gaskets in the kit that I thought were for the oil bath to carburetor neck and thought I got lucky that they sent an extra until I realized the second gasket was for the reservoir location you have indicated. Unfortunately the gaskets came in the carb kit and didn't have any separate parts numbers associated to them. Good to have the information you provided for next time when I am not buying a carb kit. Thanks for the info. Dave
