Induma/ Imperial Vert Mill oiler question
I've got a new (to me!) Induma / Imperial vertical 9x42 mill and I'm not sure about how the oiler is supposed to work.
I don't have a manual to check so I'm in the dark here. Who has a Induma and knows about how the oiler works? If anyone has a scan of the manual that they could email I would be very greatful.
Thanks so much.
In Pic 2 the knurled screw is the filler cap.
To operate, you pull the handle out against it's spring,hold for a few seconds and release. which draws oilin to the pump and the spring pressuse pumps it through the lines.
If it's been allowed to draw in air,pull knob as above and bleed the pump by loosening the outlet union in the flange as in PIC 3,......... from which I've justt seen no pipework is connected !!
FWIW its an Italian BP clone, even the BP toothed back gear belts fit.
I haven't got a manual but thse folks are the only place I've seen them
Thanks Limy Sami!
Now to figure out the pipework routing.
Thanks for the link as well.
That's "very" interesting to hear that the BP belt fits. I struggled to get one for my mill and finally sent to Italy and got a Fenner belt from them. My oil pump was useless so I mounted an aftermarket oiler on the machine with a little creative plumbing & all has been well for some time.

Last fall I did a pretty extensive re-work on an Induma (same as yours) At one point the oiler needed attention.
It functions as Limy described, which in my case wasnt very well... I had the table off and a good view of the lines and manifold and could only get a slight dribble out of one line (there are only 4 total). I did a complete disassembly of the system, finding it to function just like a typical Bijou set-up. As such, with age and sitting up for a long period, the metering valves and lines were clogged up. I managed to get flow back thru them and took the pump apart and done a thorough clean on it. The end result wasnt especially impressive, I think mostly because of there being only 4 outlets. I had to pull the handle with steady pressure for some 20-30 seconds feeling it slowly extend, when it seemed to reach its end, release it and it would slowly retract which was the pumping action.
Do you think I'd be better off setting up a bijur one-shot system instead of trying to rehab the stock oiler?
The Induma is a one shot system just with a different pump,............ if that's ok, and as has been said a good clen up usually cures all ills, I'd stick with it and uuse the Bijur meters as required.
I found soaking the lines and fittings in cellulosse thinners broke up the gummy oil nicely.
Once sorted out, my pump's given no trouble.
Thanks Limy Sami.
I'll source meters and run lines after I clean out the system.
I rebuilt the pump with new o-rings last night and it pumps well now.
I really appreciate your help.
Indumas are getting pretty long in the tooth now mine I think is 1964 so......
While you've got the table off, check the feedscrew thrust races, they fill with coolant and get rough. They're a std metric ball thrust race (35mm bore if memory serves), and quite reasonable price wise.
I'll take a look at thrust races while the table is off.
I really appreciate the help Limy.
