Hi Mate,
I'm not entirely sure what your talking about, but their should be two points in which to oil up your bevel boxes. JAck the Ferret up so that the wheels are off the ground and rotate the wheel so that the 'filler' on the outside hub (the one you can see when you are standing beside the vehicle with the wheel on, which requires a hex key to remove, is at 3 or 9 O'clock. Fill it until it overflows. Put the cap back on. The external hub is full.
The inter bevel box. For the front, on the outside, remove the filler (see attached picture). You will see that this filler is blocked by the steering arm, so you will need to turn the wheel, so that it is clear and you can put a socket on it. take out this filler bolt. Now, the front left is easy as all you need to do is get inside the hull and remove the filler plug on top of the bevel box, which is situated beside your left knee, when you are sitting in the drivers seat. Place a bucket under the bevel box under the ferret just under where you have removed the bolt behind the steering arm. Get back inside the ferret and carefully pour oil into the bevel box from the inside filler plug. Do this into oil spills out of the external bolt hole. This bevel box is now full. Put the two filler plugs back on.
The other three are a bit more tricky, as access to the inside filler plug is not so easy. So, what I do is take the external filler bolt off and get a bit of garden hose about 1 mtr long and place in the hole. I then get a funnel and force it into the other end of the hose. I then slowly slowly pour oil into the funnel and let it slowly fill the hub. This process is slow, but a lot quicker than trying to access the filler plugs from inside the ferret. After I think it is full, I let the oil settle into the bevel box and come back about an hour later and have another go at it, just to make sure its full.
This is my system and seems to work. Others may do it differently and have better ways of doing it.
