Hello All, Just starting out. I have most of my parts for a two shaft turbo shaft (free wheel i guess). My question is: Will the turbo's bearings be suitable lubricated if the shaft is in a vertical position, And would there be more idle leakage of oil.
Great Group and Thanks

hello and welcome to the JATO forum
i think that it wuldnt be so suitable with a vertical shaft,the oil would build up in the lower region of the bearing housing and put a strain on the shaft seals,it should flow easely from top of bearing housing to bottom..i dont think that anyone tested it really....

Hi Rowbo
Yeh , as Stoffe said, turbos are designed to have the shaft in a horizontal position give or take 30 degrees one way or the other , but definately not vertical .
The bearings in a vertical shaft turbo would be lubricated OK , its just the oil drainage thats the problem ........................it depends on whether you want both the gas producer and freepower shafts vertical , or just the freepower .
Whats the proposed application , .............I might be able to supply a solution :-)
Cheers
John

Thank you guys
Being at the start of the project makes it easy to change back to a normal, horizontal on both shafts. The project end use is mainly to learn about DIY turbines/ turbo shafts, and get some welding and fabricating experience. I will drive a alternator and may drop it into a cart but I tend to get a kick out of just building things (can anyone relate). I am driving a T3/T4 with a T25/28. As I can see from the posts it's time to start doing some math.

Hi Rowbo
They're both pretty small turbos , I'd be getting the gas producer running and well sorted before thinking about the freepower stage , very small gas producers don't always leave a lot of energy for making power , you may need a larger freepower stage .
Yep, never too early to start doing the maths :-)
Mmmmm , the thrill of "just building things " ................heh heh , being on my 6th engine build , I might be able to relate to that ;-)
Cheers
John
