Gearbox oil filling

Why do you have to fill gearbox from bottom up ? and then need a special pump, why not from top oil hole ??
Thanks

You create an air lock if you fill from the top and you won't get enough oil in. You can get a bottle of oil with the fitting and pump fairly cheaply. Once you put in the top screw the oil will stay more or less by gravity.

If it is something you do occasionally, you can just buy the fitting needed, and use a couple of squeeze tubes of gear oil. If changing oil often it is more cost effective to purchase oil in bulk and pump it in.

Another trick is if you use silicon sealant in tubes, clean out a couple of old tubes and load them with oil. Use a fresh nozzle cut to size and pump it in with the cartridge gun.

Do what I did. Cut an old lemonade bottle bottom off, attach a tube to the neck connecting that to the oil fill hole at the bottom of the gearbox. Attach the lemonade bottle to the leg using cable ties, make sure the fill level hole at the top of the gearbox is somewhere level with bottle and just pore the oil in till it comes out the hole. Plug back in top, tube out of bottom and plug in bottom, job done and not a pump in sight!

I like that idea, simple low tech, cost effective

Top Tip: Keep the oil someplace warm (hot press) for a few hours before you fill the gearbox - the oil is quite viscous when cold and thins as it warms.
