1.
Once the pump is disassembled, proceed to
drain the oil in the gearbox. Use the cap nut
(51)
on
the bottom of the gear case
(10)
. If the oil is in good
condition, keep it in a closed reservoir in order to
avoid contamination. If the oil is dirty change it with
new one. View oil section
(page 15).

Loosen the hexagonal bolts
(33)
and pull back the gear case. Inside are the gears that drive
the pump. The drive gear
(41)
is driven with a key, while the driven gear
(42)
is locked by tapered
rings.
Note: The tapered rings while loosen will make the idle gear rotate without transmitting any
motion to the shaft. If the tapered rings are tighten, the driven gear will rotate with the shaft.
4.
Undo the socket head cap screws
(46)
and remove them all. All screws have a lock washer
(45).
