First off I went around finding a turbo that would work for this project, I ended up finding a Garrett T04 turbo that I got from Injection & Turbo in Topeka, Kansas. When I was there I asked the them for a used turbo similar to a T04, and the manager pulled up a turbo from the back shelf that came off of a John Deere tractor, and he said," you can just have this one." so once I got a lubrication system and exhaust flange put together, I spooled up the turbo with a shop vacuum, it turned out to run pretty good. it has quite a bit of up and down play in the bearings, so I'm thinking about looking on Ebay for a rebuild kit or a whole new turbo.
Now I needed a way to pump, filter, and cool the oil for the turbo.
So, first I needed to find a way to pump the oil, then I started hunting around my Grandpa's shop for small hydraulic pump, with a some searching around, I found a Cessna oil pump, I wasn't sure what model of airplane it came off but it looked perfect for the job. Then I just needed a motor to put some driving force to that pump. I found an old automotive fan motor with a fan already attached! So, now I just needed to make a bracket to hold the motor and pump together, then I needed a shaft to transmit the power, I ended up turning a steel adapter shaft that will allow me to use a piece of rubber hose over the hub on the fan to drive the pump., when I tested it, it preformed without any trouble, but the pump slows the fan to the point of not being effective for cooling, I'm thinking that I may need a separate motor to drive the pump, with that it will be possible to adjust the oil pressure without decreasing cooling effectiveness.
Testing the pump, the camera's shutter completely stopped the fan, but it really is spinning.
Last, there is the oil cooler, which was made from heat exchanger off of a car heater,
it turned out to work pretty good, I found not one leak. Then I just made a handy bracket to hold it with a piece of
expanded metal screen to protect the cooling fins.
Now I put it all together on a piece square tubing and it made a
nice compact package that will save space for other systems.
Now I need some little odds and ends, mostly hydraulic plumbing stuff. so in the picture below it shows some of the parts, brass fittings, hose, 5-30W synthetic oil, and a few pressure gauges. From what people tell me, turbines love synthetic oils because they can handle extreme temperatures and still maintain their lubrication capacity, and a good viscosity is 5-30W oil, which is great for turbines.
Until the next page, see ya later, Heath Jepson.
