Novakon Torus Pro oil leak issue log
Hi,
Starting a new thread for the hardware issue I am facing right now. Hope this thread will help me in fixing oil leak issue and will also help folks in the future with similar issue.
I do have Novakon Torous Pro mill for couple of months and using wood to practice cnc/milling and guess am ready to move to metal as soon as oil leak issue is resolved and I can use the coolant.
Is the issue real or am I too picky. I know machines do have some oil. I cleaned the machine pretty good about 4 days ago and in four days I do have enough oil on the tray to soak at least four paper towels. Beside the tray, I also cleaned all the visible oil joints and did not see any joint with excessive oil on it. Also cleaned all the ways (hope this is the correct terminology).
Pump lever do take some force coming down but it does go back very very quickly. I did get some input from other thread which will require me to take apart the pump. First step would be to loose nuts for two lines on two sides .... so the first question ... will oil just come out if I loose line nuts and take apart the oil lines? plan is to take the pump out, empty it and then work on input from other thread on screen, gasket, rubber ring, spring etc.
Novakon is been good to me during machine set up and I am in touch with them on this issue. Novakon advised me to use heavier oil, which did not help. Hope to hear from them after the break.
Happy holidays.
Cheers

Now in the correct thread.
The lube oil?
I've dismantled one of those oilers and the seat the ball seals on was made with a drill, and the diameter was way oversize, and the seat a heap of bumps like a drill often makes.
You need to form new seats for the spring loaded balls. The pump I repaired has not leaked one drip since.
There is a springloaded ball (or should be) to stop drain back into the pump.
If there are no air leaks the exit ends shouldn't weep oil.
Is the lamp holder a bit saggy?

One reason why I chose the Novakon CNC machine instead of the Tormach CNC machine - Page 3 - CNCzone.com-The Largest Machinist Community on the net!
Proper operation of the oil system
Technical overview:
We have been looking at this problem in depth for awhile. The Torus PRO factory has been involved in evaluating the problem and providing possible reasons for the leak as well. While the numbers of reported occurrences that are similar to this are very few, it did occur in this situation and at least in one other situation we are aware of.
The oil dispersion system used in the Torus PRO is misunderstood. The oil pump is designed to pressurize the oil lines when the handle is pulled. When the pump is in the static position, it does not mean that oil cannot bypass the seals inside the pump. The components that prevent continuous flow are the flow valves that are used throughout the distribution system. Each line radiating from the oil port has a flow valve that prevents flow of oil until sufficient pressure is applied to allow the oil to evenly flow between all the multiple ports. If any one of the valves is leaking, this will cause this situation.
We do suggest finding the line that is seeping oil and replace the flow valves that are associated. In this situation, our customer has difficulty in replacing the suspected flow valves so the only prudent procedure is to place the pump to a lower position. This was already accomplished by one other customer and has solved his problem. There is no reason to believe this will not fix this problem. As it stands, we are looking at relocating the pump to a lower position that is more accessible from the front of the mill. The current position of the pump is not an easy location to reach to pull the handle.
We will exchange the oil pump, but we don't believe it will solve the problem. The solution is to replace the flow valves. The next best solution would be to relocate the pump to a more strategic location if the flow valves cannot be changed.
We hope this clarifies the operation of the oiling system . While it may seem easy on the surface, the solution is more complex and needed more evaluation before a recommendation could be offered.
Regards,
Novakon Team
P.S. This assumes of course that there is no leak due to a broken oil line or an improper seal from a furrel in a connector.
