Getting the Trommel back in action

Just getting ready for the upcoming prospecting season and thought I would get the trommel up and running. It has been sitting in the back yard for some years - I put some new fuel in the tank and it started again - the first time !!!. Sometimes the old and reliable is better as it has often proved its worth (although it looks very much worse for wear).

Just wondering - a 2:1 gear reduction box runs the trommel box - I would like to change the gearbox oil (all I know is that there is a drain plug at the bottom of the gearbox) - do I simply use normal engine oil or do I need a specific transmission or gearbox oil ??

Cheers De

Looks like the donk is a Honda, so I would expect it to run first go.

Gearboxes normally have a heavier oil than motor oil depending on the nature of the gearbox.  I am not a qualified mechanic, but if the oil in the box looks reasonable (flows, doesn't have water in it [milky]) and especially if it is reasonably clear, I would just top it up with a similar consistency of gear oil if it is low, rather than change it all.

Hi, that is a sweet looking little machine you have there   , I hope you will show us some more pics or video even  when you have it in action , I would love to see the recovery you could achieve with a small unit like that, does that motor cop much spillage when it runs, I would love to play with a toy like that, much better fun I think than a dryblower ...eh Lee!       I think when I grow up I want to be a prospector     , good luck with it Country Girl .

The best pic would've been of the gear box

Belt driven gear box? motors not screamen, I'd go with a straight 90 weight gear oil, maybe a tad lighter, but certainly not engine oil!

Thanks - great suggestions, here is the trommel gearbox:



It has not been serviced for many years (ever ??) - the heavier gear oil sounds like a good starting point.

Kindest Regards De

Is that a sight glass on this end of the gearbox?, do the poor old girl a favour ( and yourself in the long run ) give her a new drink of oil and then you know its done, oil is fairly cheap..gearbox's ..not so much .
