I took the tube and screw in fitting off of a manual pump (shown above) and installed it on the discharge of a drill driven oil change pump. Use a short piece of garden hose on the suction and fill from the oil container. Easy and neat.

I have used this exact unit from Stevens Instrument. Probably the best one out there, it has a quick disconnect and you pump up the pressure and just let it fill the drive up. There is a valve right at the coupler to shut off the flow when drive is full. Unit is around $150.

I use the quick disconnect to shut off the flow and let the drive equalize, once I see oil in the bottle. I can offer it with a canister, but have not found a suitable unit yet...

Thunderstuck, you've got the ticket! Men work better with good equipment!

I have been using the same thing that "GOODT" has, but it takes several minutes and A TON of pumping, but now I use the DRILL DRIVEN oil change pump and it fills the drive in about 2 minutes!!! I DO like the quick disconect with the shut off valve that comes with the Merc oil pump container, but the 90* fitting doesn't work well when using a drill pump (too much of a resistriction). A straight fitting works much better. I still would like to use something that has a shut off valve where it couples on to the drive just to keep things from getting too messy.

Mark,
with my setup you can screw the fitting in, using the quick disconnect as a handle. When it is seated you just connect to the hose (with the disconnect) that is attached to the pump. When it gets to the bottom of the bottle, you pull the disconnect apart and let the pressure that builds up in the drive, equalize. The disconnect is the shut off type so there is no spillage. Ben uses two of the fittings so he can fill one drive and then jump to the other while it equalizes. I can sell any combination that some one might want..
Hey has the ice gone out in South Haven yet. I havent been that way lately?? *S*

The oil pump is the least expensive item in a quality setup. It is the fittings that bring the cost up..

Buy the Quicksilver unit ($ 7.00) and use only the fittings on a small pump up sprayer from Home Depot ($ 20.00). You can then fill the sprayer with several quarts, pump it up and it will slowly fill the drive, instead of you pumping and pumping from quarts. Works great and the reservoir is large enough to store enough lube for a couple fluid changes.

The best and cheapest marine tool made!!

I'm trying to rig up a pump and need to know what thread size
the drain plug/fill fitting is?

I made a gear lube filler from a cheapie 1.5 gallon garden sprayer and just bought a 7 dollar hand pump at west marine and used that to adapt to the garden sprayer. Works perfectly,, couple pumps and the wand locks on and you sit and watch it fill. Takes about 1/2 beer and when oil flows outta the top your done. I have like 15 bucks in it.
