4.7 Oil tank
The oil tank should be installed as high as possible, so that the oil level in the tank will always
be higher than the pump inlet level. The suction hose (2½” - 3”) from oil tank to the pump and
return line (1”) must be kept as straight and short as possible. The suction hose must be
properly supported.
The sizes of oil tanks in factory delivery are from 20 to 53 gallons. The 20 and 26 gal oil tanks
are available with low flow or high flow return filter and the 40 and 53 litre oil tanks with high
flow return filter. The oil flow capacity for the low flow return filter is 60 gal/min and for the high
flow filter is 120 gal/min. The filtration degree for both is 10µm.
The dimensions of the oil tanks are shown in next page.
It is important to choose the oil tank location to be accessible for inspection, filling and drain-
ing. The oil level checking is a daily routine so visibility of oil level gauge is important.
Before filling the reservoir check that the interior of it is clean.
Ensure that the fastening of oil tank to the hooklift subframe and truck chassis can properly
carry the weight of tank and oil in all conditions.
