AndyH Posted January 31 Report Share Posted January 31 Hi, I recently acquired a second-hand pugmill from a local pottery (see pics) The previous owner said the gears had been replaced and that after using it for the first time I should replace the (hypoid) oil, which will remove the leftover swarf from the new gears etc. Can anyone recommend which type of hypoid oil I should use? There seem to be so many :-( Thanks in advance Andy Quote Link to comment Share on other sites More sharing options...
Russ Posted January 31 Report Share Posted January 31 Can you get Lucas oil products over there? AndyH 1 Quote Link to comment Share on other sites More sharing options...
Bill Kielb Posted February 1 Report Share Posted February 1 If you absolutely do not find a spec, I would consider trying hypoid general purpose gear oil, likely in the 90w range and observe the heating in early operation. I would hope there are no significant swarf to speak of from machining operations and he was concerned about break in.

Hulk Posted February 1 Report Share Posted February 1 I'd started looking this morning, then had to run... Hi Andy, Welcome to the Forum! Good question. I'm not finding a specific reference for oil types/viscosity for Podmore pugmill... ...nor for "Opperman spur reduction" gearbox, which appears to have been standard for some time with Podmore pugmills. Hypoid oil is important for ...hypoid gears! Still have the drained oil? Might be helpful for comparison. You might go with a semi-synthetic (cheaper than full synthetic) multi-range hypoid gear oil. How warm/hot the gearbox gets, important, as Bill has pointed out. Bill Kielb and AndyH 2 Quote Link to comment Share on other sites More sharing options...
AndyH Posted February 1 Author Report Share Posted February 1 Thanks everyone for the comments. In brief reply: I can buy Lucas oil products in the UK; I live in the north of England so it doesn't really get too hot (wet, yes ); I'll keep an eye on its operational temp as I run it in, using semi-synthetic 90w, or similar Andy Quote Link to comment Share on other sites More sharing options...
Mark C. Posted February 1 Report Share Posted February 1 90 weight is my best guess Quote Link to comment Share on other sites More sharing options...
