Lower Leg Oil Change.-

[Locozodiac]

Was wondering which method do you guys use to change the lower gear oil and which type of container is used to collect the old one ? Share your experience.

Drain the old oil into any container via the drain plug. You also need to remove the upper plug to allow air in/out.

Refill with fresh oil using a pump and hose with the correct screw in adapter. Again via the drain plug until it comes out of the upper hole. Replace both plugs.

I use the toothpaste tube gear oil which has a tapered nozzle which will push into the drain hole and then grip when turned a little as if screwing in.

Also given that the drain/fill plugs are in running water always replace the sealing washers each time with the correct makers type... not some generic type.

I used a modified Gunsons Eezibleed with the screw in adaptor from a manual pump kit. Worked a treat!

Hello

You could also use cheap red or brown sauce bottles and nice and cheap

[Locozodiac]

This is a 2 part question. Agree on the standard oily and messy procedure, what do you guys use to collect the used gear oil exiting the lower drain plug.

Well anything from an ice cream tub to a car oil drain pan.

I use old washing up bowls when changing oil/fluids on the cars & the same when doing the outboard.

Once the filthy oil content is collected in the mentioned containers, assume it's collected in other container to be disposed properly, or you like throwing it directly down the drainage ? LOL!!

We have dirty oil tanks in our local rubbish tips

A washing up bowl works well to collect the oil in. As mentioned above, you can dispose of it at your local tip in the "waste oil" section.

[Fenlander]

Yep likewise... waste disposal site 5mins from home takes old oil.

My boating Club takes care of the old oil changed, mainly to lubricate things and to oil brush trailers living close to salt water.

Recapitulating the theme...

Been doing myself lots of Gear Oil changes through the years, recently my beloved doggy flipped 300 CC of used oil collected in an open container and made a huge filthy mess in my garage, decided it was proper time to find a much cleaner and friendly oil method and came up with this nice one, was hidden in front of my eyes all the time for years. Check if this method works for you..

Gear Oil Change :
Will need to count with an Oil Pump of your preferred brand, must not have a metal clamp permanently pressing the hose against the nozzle.

Procedure :
-Sit motor upright, disconnect hose and plug adapter from pump’s nozzle.
-Remove lower drain plug.
-Screw adapter to lower plug and attach a bottle to rear hose deep enough as in pic 1.

-Remove upper plug.
-Let bleed slowly the whole contents of the gear box into the bottle.
(Proper time to entertain yourself zipping many cold ones while waiting)
-Once finished remove bottle from hose, place cap and discard bottle properly pic 2.

-Without removing the adapter, insert the hose extreme into the pump’s nozzle.
-Pump gradually new gear oil till exists through upper plug.
-Screw upper plug tight.
-Remove hose adapter, screw lower plug tight.

And that’s all folks. No more pans to clean, tons of towels to discard, floors messed with oil spills to clean and best of all a Happy Admiral…

If there isn’t any plastic, rubber plug adapter provided with the Oil Pump, want to leave the bottle with oil leftovers along attached pump’s hose, insert a thin wooden sushi stick cut to size inside the adapter, will prevent unwanted oil spillage if plunger is pressed by mere accident which I leave opened for spring to last longer working properly as won’t know when will next gear oil change take place…

Note : Depending on the quality of the material used on the drain plug’s gaskets, if in good shape, that’s not deformed, excessively compressed can use them again, don’t over tight them when screwing plugs back in for a long lasting life.

I take mine to work and pour it into my waste oil burner helps towards keeping me cosy during the winter

Reusing washers is how you end up with cloudy water like the picture - given the only way to check that is to loosen the washer and relighted yet again I’d always replace the very low cost part when changing gearbox oil.

[Fenlander]

The other problem I've seen** is where the OE seal was a medium to soft fibre type that is larger than the plug head diameter... but it has been replaced with a plastic washer with less contact area which may not seal and to try to get it to do so needs the plug to be overtightened.

**Think Suzuki dealer at first service!

I know proper marine grade gear oil is designed to lubricate with a degree of water mixed in but I'd hope not to drain out anything like the left hand bottle in post #15.

Wrong washer? Wee buns, mine used no washer at all! Gear oil all over the boot on the way home!

[Locozodiac]

The used gear oil collected is yellowish with no water contents or even emulsified by salt water coming in through lower leg whatsoever, have tried same oil brand on other motors's gear boxes and comes out same color after 100 woked Hours. No way will come out same color as when new.
