Thought I would share some pictures and ideas on how I modified an air filter housing to use a modern filter. To start, I want to say that my housing was rusted out and if it had not been, I probably wouldn't have done this. The old down side to this set-up is that the filter must be oiled to work properly, so either way you going to be playing with oil during service.
PICTURE 1, 2 & 3: You will notice that I have two tool box latches securing the top dome to the shell which additionally sandwiches
the filter plate between the two.
PICTURE 4: This picture of me holding the top / dome, with the bottom towards the camera, you can zoom in on the edge and see how the
outer rim is double layered. That lip that is a bit jagged was crimped around an edge on the shell circled in Picture 5. I used a
small screw driver to open up that crimp to separate the dome from the shell. I then crimped it back down to eliminate a sharp
edge.
PICTURE 5: The yellow circle identifies the horizontal lip on the shell that the dome is crimped on to. I put door edging around it to eliminate the sharp
edge. I did not cut it off because it give the shell some extra strength. You will also see that I cut the bottom out of the oil cup and
also used door edging to eliminate the sharp edge.
PICTURE 6: This shows the plate and tube I welded up to accept the filter. I put soft rubber, inter tube I think, around the outer edge on the
bottom and top to use as a seal. After several thousand miles, it seems to work well. There have no signs of dust or dirt in the
dome. The filter was a stock item at Pep-Boys in their rice rocket section.
The rest of this is pretty self explanatory. Aside from the tool box latches, it looks stock and those unfamiliar with old jeeps would never know it isn't original.
