4.5 Hydraulic pump installation
Before installing the pump check the pump manufacturer’s instructions for the dimensions, oil
flow, torque, power and rotation speed and direction. The recommended oil flow and working
pressure of the hooklift can be checked in the table in page 28. Under-sizing the pump will
cause to too slow operation of the hooklift and over-sizing the pump will cause unnecessary
warming up of oil.
Check that the pump fits to the location to be installed and that the hooklift or other compo-
nents do not prevent the installation. Check also the truck manufacturer’s instructions.
The most common pump type in hooklift use is a fixed displacement pump installed on the
gear box driven PTO. Alternative pump type is a fixed displacement pump installed on the en-
gine driven PTO. In case of Ultima Flex or Pro, a variable displacement pump use is possible.
Before first start of the pump, remember to fill it up with hydraulic oil. Check the pump manu-
facturer’s instruction on filling up and other possible procedures.
4.6 Variable pump LS line installation (Ultima Flex & Pro)
Check from the hooklift order if the Ultima control valve has factory installed LS line configura-
tion for variable displacement pump. If it is so, then connect the LS line to the pump according
to instructions in next page.
If the control valve is as standard for fixed displacement pump, then the valve configuration
must be changed. The needed tools and working order are shown in next page.
Check if the compensator blocking pin p/n MU114131501 was ordered to the hooklift delivery
and if not, then order it from Hiab WebShop.
