    Grinding paste coarse-grain

    For valves of petrol and diesel engines.

     

    1)  Recommended for the valves of vessels engines

    2)  6 types of grains depending on FERA

    How it works 

    Grinding is a process of removing of the thinnest layers with small grain size abrasive powder merged in lubricant by the use of special instrument.

    During this treatment the paste removes all roughness.

    The paste provides

    • 90% hermeticity of the valves

     

    • Use FABO (ANF) paste to achieve 100%  hermeticity

     

    • Improvement of the performance

     

    • Increasing of compression in the combustion chamber

     

    • Reducing of the oil burning

    Properties and application

    Paste contains abrasive powder F180 and F320 with average grain size 50 mkm


    Advantages:

    • comfortable batcher form allows easy and equally apply paste on the valve;
    • rough and finishing composition;
    • contains components accelerating time of lapping;
    • paste retention in contact zone

    How to use:

    1. Put the valve into the head of the box
    2. Apply a thin layer of the paste
    3. Fix the valve stem
    4. Turn the valve two-ways pressing the valve to the valve seat
    5. Homogeneous mat grey colour of the valve face and seat means well grinding
    6. After grinding wipe the valve and the seat with a clean rag and wash to remove the rest of the grinding paste.

  • Grinding pastes. ARE THEY NECESSARY?

    Finnish expert in preparation of sports cars engines Toumo Kurki-Suonio tried to answer this question. Engine repair shops do not lap valves after machining on a lathe. They are save time, claiming that the valve is tight enough.
