Gear Oil Change

Like most of you, I have been changing my gear oil with the little hand pumps that are very slow and hard to use. It occurred to me this morning that there is something about this process that doesn't make sense to me. What if I drained the drive and put the lower plug back in and filled the drive from the the expansion/safety bottle at the top of the engine until it started dripping out of the top plug on the drive? Then I could put the top plug on the drive back in and fill the expansion/safety bottle to the required level. This would be much easier than using that little hand pump. I know there is something wrong with my logic since this is not the standard procedure but I don't know what it is. Anyone have an answer? Thanks.

Id just make sure you have a pump that is @5psi. You don't want stupid high pressure.
I've used regular automotive electric fuel pumps over the years to pump old gas, diesel, gear oil, old engine oil and hydro fluid. I've used efi 45 plus psi pumps and carb specific 5 to 6 psi pumps. Just make sure whatever you use is self priming.
The only difference I found was the carb pump was slow!!!
Like others have said, warm it up. On a 70 degree day you shouldnt have an issue of needing to warm anything. On a 30 degree day, you might have flow issues.
90wt oil isn't much thicker than diesel. 90wt is close to about 40wt and diesel close to about 10/30w
They were amazing. Sadly they didn't last very long once all the fuel started containing ethanol..
I quit buying them as they stopped working after a year and they are not cheap.
That's when we went to the electric pumps. We. Hook up the pump and by the time we are done pulling plugs, filters, etc shes drained.
Having the right tools makes a job much easier.
When you have hundreds of items waiting for a service, just 30 seconds per repair adds up.
About 2 years ago we built a rocket stove. We burn pallets and all or old gas/waste oil for heat now.
Now we dont separate gas from oil. I find a 50/50 oil to has drip burns and flows best
Do you use an oil burning furnace?
Every now and again I'll have the drip a little too fast and she'll smoke like a diesel tractor pull.
We'll have a customer come in and ask if the shop is on fire.
