I want to drain and fill the differential.
At the front of the differential is a plug with a square recess. Is this the fill plug and should oil be filled to the bottom of this hole? What is puzzling to me is that all the differentials I have encountered take oil to a level just above the bottom of the axle tubes, and therefore below the centre line of the differential. This plug is above the centre line, so the differential will be more than half full of oil if filled up to this plug.
There is another plug further up that has a hex recess, thus taking an allen key. What is this plug for?
I did not jack up the forklift, so I did not see the bottom of the differential. Feeling under the differential, there are two plugs located at the back and towards the bottom of the differential. These have hex heads on them, thus taking an ordinary wrench. Is one of these the drain plug?

Well, I will answer my own questions. I lifted the forklift today and found the drain plug at the very bottom of the differential case. The fill plug is the one at the front of the differential. They are both 1/2 in square recess and can be driven with a 1/2 in extension on a ratchet.
The oil level is to be at the bottom of the fill port.. The fluid capacity of the differential on my truck is 6.4 l and adding that amount after draining the old oil brought the level up to the bottom of the fill port.
I used 75W90 Spirax by Shell.
From Admin....Sorry again, it appears I got the link copied incorrectly last time as well. Here is a new link to the photo, at photobucket dot com that applies to this post.
