Engine Oil Priming Tool

prime_tool_5.jpg - 13144 Bytes Any time you start an engine which has been rebuilt or has been sitting for a prolonged lenth of time without proper maintenance, the oil galleries should be properly primed. To do this, you need a priming tool.

You can build an excellent priming tool out of an old distributor. Here we build one for a Buick straight eight. The major components are shown on the right. The piece of pipe is 1/2" id.

First we cut a piece of the pipe the same length as the distributor drive gear. Then run a 1/2" drill through it so that it will slide onto the distributor shaft. You can use a variety of fastening systems, but I weld mine, so I have drilled a 5/16" hole in the side of the pipe. I will be able to "plug weld" it when I am ready. Prime_tool_6.gif - 18018 Bytes

I like to make pretty tools, so I cut of the upper part of the distributor housing. I then remove all unnecessary parts from the distributor shaft. Again to make it pretty, I removed all evidence of the distributor weight mounting plate. I am now ready to assemble the priming tool.

Now if you like nice tools, you can clean and paint your first class engine oil priming tool!

To use this tool, insert it into the distrubutor mount, and clamp a 1/2" drill onto it. The pump will take a good bit of power to turn.

Your engine is ready to run!
