1. General Introduction
This document covers the instructions for
installing the vane pump upgrade kit 180F4161.
Important: It is essential that the iSave and
vane pump are serviced in conditions of absolute cleanliness.
For a better understanding of the vane pump and
iSave, please see the exploded views in the sections 5 and 6.
The weight of the iSave is 65 kg / 143 lb
and it must be lifted with suitable lifting
equipment.
To prevent cold welding, lubricate threads of
screws with grease; screw them into the component and tighten them by the hand. Use PTFE
lubrication type.
Tools needed for upgrading vane pump::
- 10 mm socket
- Torque wrench
- Adjustable spanner
- Loctite 270
- 6 mm allen key socket (160 mm long)
