Bill--I received #74 oil seal. It fits on the shaft between the housing and the outer bearing but there isn't enough room to reinstall the retaining clip.
I though this was the right part?
Please advise..Thanks
Dave
Bill,
Eureka!!! I finally got the oil seal to fit and reassembled the jigsaw with your expert advice. No leaks and works like a charm!!!
You have been a great help, thanks for saving me money and time.

My 'new' jigsaw (1984) is now purring and not leaking out of the front bearing seal due to the new replacement. It is -however- seeping from the gasket and on the very bottom of the vertical shaft cylinder. It's so slight that I could live with it for a few years. Just curious...does anyone know if you can replace the cap at the bottom of the vertical shaft cylinder? not sure why it's leaking a little.
Cuts like a champ though...Dave

The cap at the bottom of the vertical shaft cylinder is an aluminum concave (dome) 29/32" expansion plug. It is a metal to metal fit and appears no sealer was used. I have been unable to find a retail source for this size aluminum concave (dome) expansion plug. I have sent Emails to several manufacturies asking for for the names of their distributors/dealers.
I have been removing them with a long punch down the vertical shaft hole. I have been redoming the plug by setting it on a 3/4" socket with the outside/bottom down and placing the round part of a small ball peen in the center of the plug, I use a larger hammer to make the plug more concave/domed. Then I use red LocTite (permanent) around the edge of the opening and with the dome being out, I flatten the dome until the plug is firmly seated in the housing. This has worked for the couple jig saws that I did so far. I have not tried putting LocTite down inside the bottom of the vertical shaft cylinder to see if it would seal any leaks but it may work.
I still have not made any housing gaskets from the different gasket materials I brought. I brought another jig saw (6 now leaking) that the housing gasket seeps oil so it must be the original gasket material that over time/aging allows the oil to seep. Be sure the vent hole is open as it can get filled with crud or paint if the housing is repainted. I use air compressor oil for the jig saw.
