PUMP FOR HYDRAULIC SYSTEMS

Installation and maintenance manual

5.1  Ordinary maintenance

5 MAINTENANCE

Poor installation and maintenance may result in loss of steering and cause property damage and/or perso-

nal injury.  Maintenance requirements change  according to climate,  frequency and  the use.   Inspections are

necessary at least every year and must be carried out by specialized marine mechanics. Check the cylinder

fittings and  the seals  and the  helm gaskets  to prevent  leaks. Replace  them if  necessary.

To keep  a suitable  oil level  in the  tank, fill and  bleed the  system as  described in  this manual  in paragraph

3.11 and  in the  bleeding procedure  of 

UFLEX

  cylinders. Check  the  hose and  the entire  system  wear,  the  nut

and  bolt tightening  every  six  months  and  make  sure  that they  are  not  damaged. Clean  the system  using

water  and  non-abrasive  soap.

Use only compatible hydraulic  oils, indicated  in the  paragraph "technical  features" and  "filling and  purging".

Do not  use brake oils or  automatic transmission  fluid (ATF)  in  any case.

WARNING

DANGER

5.3 Troubleshooting

Whenever  the following  checks need  the removal  and/or disassembly  of  the  steering system  components,

such work must be carried by specialized staff. 

UFLEX 

offers general information only and is not responsible

for  any  consequences  resulting  from incorrect  disassembly.

 PROBLEM

CAUSE

             SOLUTION

Blockage in the hoses between

steering  system and  cylinder.

Air in  the system.

Leaks  from the  cylinder

bleeder.

Coiled  hose.

Helm has been mounted upside

down.

During  the  filling,  the

steering system  becomes
completely  jammed.

The system is very difficult

to  fill.

Air keeps  bubbling  at  the

top of the steering system

tank even  after filling  the

system  completely.

Replace  hoses.

Repeat the   filling  and the  bleeding

procedure  of  the  system.

Install  horizontally  the  hoses  and  in

any case with a  maximum inclination

of  3cm each  meter.

Tighten the  bleeder on  the   cylinder.

Uncoil and  straighten  the  hose.

Mount the helm with the filling hole in

up  position.

WARNING

DANGER

The  damaged  hose  must  be  replaced,

otherwise it  may  cause  loss  of  steering

and  severe  personal  injury  or  property

damage.

If  the  self-locking  nuts  are  disassembled,  they  must  be  replaced.  (Contact  our  assistance  service,  see
page  6).

CAUTION

5.2 Steering wheel disassembly

To remove  the steering  wheel from  the pump  shaft, use  a suitable  extractor.

Do  not use  a hammer  or other  tools that  could seriously  damage  the  pump.
