The little nipple with the O-ring that the bar oil pump connects to was broken.
I removed the nipple from the oil pump and drilled it out with a 1/8" drill.
You can see in this picture where I removed the orange press in plug. I removed it by putting a screw into the depression and then pulling it out with a pair of pliers. This allowed me to also drill out this passage to 1/8". It took a very long drill bit to reach in there because the case gets in the way of the drill with a standard bit.
Here is the nipple with 1/8" automotive vacuum tubing press fit into it. The fit was very tight and it took some effort to get the nipple onto the tubing.
This shows the nipple in place. The tubing has been pushed into the drilled out hole in the oil passage. I used a 5/32" bit to drill out the short passage from the bar side of the case. This was needed because the tubing covered that hole.
This is the finished repair. I used a soldering iron to melt the plastic back together. I cut a nub off of the case that would not affect the structural integrity and used this little bit to build up the plastic. I worked slowly and built it up layer by layer.
I then melted the end of the tubing flush with the end of the nipple.
With some trouble I pressed the plug back into the end of the oil passage.
I believe that the tubing would have worked by itself. The fit is tight enough that it would not have leaked.
When I get the rest of the saw back together we'll get to see if it works. The melting job is ugly but looks strong enough. It is difficult access to say the least.
