Tips when changing and checking transmission oil

[Mal]

Any tricks to change and check the transmission oil (rear drive/swingarm not gearbox) as I’ve noticed that the fill holes are not real level with the bike siting on it’s sidestand at full suspension travel (compared to my CARC 1200Sport)

Shouldn’t be a problem to change it, hopefully, as it’s only 170 cc, unlike the gearbox which takes 1000cc! Just not too sure how to check if it’s filled to the correct level. I’m hoping it’s just level ground with the swing arm wherever the suspension puts it on the unloaded bike.

Funnel and hose or syringe. The later the better alternative.
Fill from level plug. I used to fill from breather plug, as it's pointing the right way, upwards. But you got the gears right under the hole, and as the transmission oil for the rear transmission is real thick, it's also a real royal pita to get it in that way. At least it demands a lot of time. And some spill. inch:

Here is a link to a good basic oil change tutorial........

I don't know about the rest of the universe, but here i the UK gear oil is supplied in bottles with a plastic tube in the top for filling, no need for a funnel or syringe.
I decant engine oil into an old one and use it for filling the sump too.

It comes that way in Australia too, but it is still a PITA to get it from bottle to gearbox, because the tube that pops up out of the bottle invariably leaks around the base :x , and it still takes ages to get it all in. I must look out for one of those syringes for next year's gearbox oil change.

Some folks just buy the small one dollar funnel at the auto parts store, works well for me. If your cheap, save the bottle that has the small filler spout and cut an empty one in half, you have a free funnel

Thanks for the info

I have some singe use paper funnels ($3 for a pack of 3 from Repco or wherever) but I use a 50ML catheter tipped syringe, $.50 if you had to pay for one. I work in a hospital.

The bottles have that tube, but I didn’t know how to measure the amount of oil I wanted. So I filled a graduated container and then just used the syringe as a funnel.

I might have to squirt it in for the 750, but the test run oil change on my 1200 didn’t go too well

I do buy transmission oil in those bottles. They are branded "Castrol" over here :mrgreen: . Works fine for the gearbox, but those 170 ml for the bevel box are hard to measure, unless you'd accept spill when the bevelbox is full.... :dry:

Biggest problem I had draining the bevel gears was preventing the oil from getting all over the back tyre.

If you will excuse the color of the oil :dry: :whistle: , a piece of bent sheet metal comes in handy here.

Holt, what caused the milky oil in the photo?

Water. :mrgreen:

(That was the reason for changing the drive shaft ingoing seal a while ago. Old one was blown. There's probably a leak in the rubber gaiter at the gearbox-end. But I can't see it. Rode in some really hard rains last summer.)
