Let’s not beat around the bush, these flushing machines come in at over £5000 each, so they are proper bits of kit!
The machines allow us to first add a flushing treatment to your existing gearbox oil and then run the gearbox at normal working temperature whilst circulating the flushing additive. Once the flushing cycle has completed we can withdraw your old oil whilst at the same time pumping in fresh, clean oil.
As the pump works with the directional flow of your gearbox, we are able to see the old oil come out and then withdraw a tiny amount of the fresh oil to confirm that we have completely flushed the gearbox. Then as a last win, we add specialist treatments. Our last check is through the same inspection port where they old dirty oil was before, now we see beautifully clean oil.
