hi
the gear box has its own oil system and filler plug next the gear stix the level plug is a little square headed plug brass plug, wen sat on the seatits near ur right leg ( if i remember right

think its that side ) , unsrew little plug , add oil at the top untill it comes out of the lille hole , replace little plug oil is full .
but the hydaulics oil , backend oil , differential ect. ( the one thats relavant ) has its own system. level plug is on the left side wen ur sat on the tractor , hiding behind the lever for the pto , above were the clutch pedal is mounted. filler is at the back above the differential , near the top link mounting piont , ( both fillers are the same size plug , wen removed will leave a big hole , prob 1 " pluss , big plug /cap )
top up in the same way both use same type of oil oil types on the dexta home page six th one down .
prob check hydaulic / backend level with loader lowered
i think there sepperate so if ure using alot of oil on a external , tipping a big traler / ram or have a leaking external service u can only lower the backend oil not the gear box level aswell , but i could be wrong on that one,
when i use my mate large renault 145 with his big dump tailer if u fully tip the trailer u start to loose power stearing untill u drop the body a bit lol obviously same oil system .
hope this helps
