Installing Reservoir For Hydraulic Pump

Information 

Ensure absolute cleanliness! 

Ensure absolute cleanliness if the reservoir is disconnected from the hydraulic pump.

If dirt gets into the reservoir, this can cause the hydraulic pump to stop working.

Information 

Driving in and securing straight pins 

If the straight pins are driven in the wrong direction, this will widen the axial stops.

The straight pins must only be driven in towards the back of the hydraulic pump. 

Always use new straight pins. Use a drop of Loctite in the bores to secure the straight pins.

   Information 

   Installing O-ring 

   Always replace the O-ring -3-  between the reservoir -1-  and hydraulic pump -5-  .

   Make sure that the reservoir -1-  is fitted without tension on the hydraulic pump -5-  .

   Leaks can occur if the O-ring -3-  becomes jammed.

2. Fit the reservoir on the hydraulic pump.
   • 2.1. Fit the reservoir on the hydraulic pump without tension.
   • 2.2. Drive in straight pins.

     Secure the straight pins by putting a drop of Loctite in the bores of the hydraulic pump -2- (-arrows-)  .

     Drive in the straight pins towards the back of the hydraulic pump -2-  using a suitable mandrel that will not widen the bore hole.
