      Ring Installation
     
    Proper preparation is essential to achieving optimum performance from your piston rings. It is imperative that all rings be checked dimensionally with the ring grooves and with the cylinder bore.

    Remove any burrs from the piston and the piston ring, they should not have any, but check! 

    Using a squaring tool put the ring in the bore to be used and measure the ring gap to make certain it is correct for the bore size and application. When measuring the ring gap it is recommended that the ring be below the top of the block at least one inch to avoid any taper from bore recession

      HELPFUL TIPS FOR RING FITTING AND SEATING
       
    All pistons (including new ones) should be checked for proper ring to groove clearances.

    Ring to piston groove back clearance should be a MINIMUM of .005" deeper than radial wall dimension of piston ring. If piston ring sticks out of groove by any amount, you have the wrong rings (see fig.1).

    Ring to groove side clearance should be a minimum of .0015 to a maximum of .003" (see fig.1).
      Boring and Honing
     

    Boring and Honing is becoming a very complicated subject as cylinder finishesbecome more refined and oils become more slippery. different honing procedures depending upon ring material, ring tension, blockmaterial, and application. If you have any questions about how your cylindershould be honed, please contact us at 800-874-2753 so that we can learn moreabout your application and designate a specific honing procedure just for you.
      Ring Seating
     


    When first starting your engine to ensure proper ring seating, do not allow the engine to idle for long periods at a time. It is a good idea to mildly load the engine as soon as you can. Highway driving is a good way to properly seat the rings quickly. Do not idle the engine as idling does not break in any engine. Total Seal ® DOES NOT recommend the use of synthetic oils during break-in. After 2000-3000 miles on the street, or one night racing on the track, the rings should be adequately seated so that any oil you prefer can then be used.

     

      Valve Guides and Seals
     


    Total Seal ® recommends using a positive valve guide seal preferably made of viton on all applications. Proper valve stem to guide clearances must also be maintained.

     

     

    Total Seal ® FAQ's
     
    QUESTION:
    Do Total Seal rings require special cylinder honing? 
    ANSWER:
    No, Total Seal rings do not require special cylinder honing. But they like all piston rings do require proper cylinder honing. One of the most common causes of ring sealing issues today is improper cylinder honing. It’s not uncommon to see engine blocks and cylinder sleeves ranging in hardness from approximately 150 to over 300 on the brinell scale. Yet it is very common to see these all of these being honed using the exact same process. The end results vary dramatically. These results are measured with a tool known as a surface roughness tester. The results are measured as Ra, Rz, Rpk, Rk, and Rvk and vary depending on the specific application. Basically these numbers are telling us to how rough the cylinder is and how well it can retain oil. An overly rough cylinder will prematurely wear the rings while an overly smooth cylinder may never seat the rings and can lead to cylinder burnishing. Cross hatch angles can also vary depending on the application, These angles determine the critical ring rotation speed, generally a 45° cross hatch angle will do a very good job. Though some O.E. applications do vary from this, if your not sure check before you proceed. To steep of a cross hatch angle can cause the rings to pump oil, rotate to quickly leading to accelerated ring and ring groove wear. To flat of a angle can cause a chattering affect as the ring passes over the valley preventing the ring from receiving proper lubrication again leading to excessive ring wear. If you’re not sure about the proper honing procedures and cross hatch angle for your specific application please give us a call. 

    The following recommendations are for most general applications.

    Ra 10-20 µ in.Rz 10 times the RaRk 30-50 µ in.Rpk 5.0-20 µ in.Rvk 50-100 µ in.

    QUESTION:
    What advantage does the gapless top ring offer over the gapless 2nd ring?
    ANSWER:
    The Total Seal gapless top ring is the natural evolution of the gapless second. By moving the gapless ring to the #1 ring groove we effectively seal the cylinder closer to the combustion chamber. This not only increases the cylinder seal on the compression and power stokes but also improves the ring seal on the intake stroke resulting in better cylinder filling on a normally aspirated engine. The increased amount of force generated by the combustion process in turn delivers a greater amount of energy to the crankshaft. The choice is yours and either ring offers superior cylinder sealing.
     
    QUESTION:
    Can I use a gapless top ring if my piston is gas ported?
    ANSWER:
    Yes, Gas porting aids in keeping any top ring seated in high rpm /
    high cylinder pressure applications.
    QUESTION:
    Can I break my engine in on synthetic oil?
    ANSWER:
    Though we have seen it done successfully on occasion we do not
    recommend it. We have seen the best and most consistent results
    breaking the engine in on light viscosity conventional oil. Synthetics
    can be used after completing the break process.
    QUESTION:
    What should I set my end gaps to?
    ANSWER:
    Please follow the gapping chart supplied with the ring set. Different
    applications require different amounts of gap. If for some reason the
    gapping chart is missing or your just not sure please call our tech
    line and they will gladly help you make the right choice.
    QUESTION:
    When file fitting the gapless ring do I need to file rail?
    ANSWER:
    Yes the ring and the rail need be filed*. Follow the gapping chart
    supplied with the ring set.
    * The rail end gap can be larger than the primary ring but not smaller.
    QUESTION:
    Which way does the gapless ring go on the piston rail side up or
    down?
    ANSWER:
    The gapless ring is always installed rail side down.
    QUESTION:
    What is Quickseat?
    ANSWER:
    Quickseat is our patented dry film cylinder wall assembly lube. It’s
    quite unique in that it is a dry lube this helps to prevent glazing of the
    rings from the over use of assembly oil. It also provides outstanding
    lubrication during the critical initial start up period helping to prevent
    ring scuffing and cylinder wall burnishing.

     

      "I've been using Total Seal® rings in my engines for over 15 years. They’ve shown the most significant gains in power through improved cylinder sealing than any gains from cylinder heads or camshafts I've tried. Equally as important is the service and technical support I've received from their sales and tech staff." - Don Ott, Don Ott Racing Engines
     

    We thought this was an accurate quote that many people may question. The following briefly explains why and how piston rings have become such a vital part to your engine’s performance and helps to explain why the above statement should be read again.

    Piston Ring Function... Sealing for Horsepower.


      There are three leak paths for blow-by to escape past the piston into the crankcase and we all know that any blow-by leaking past the piston is horsepower lost. Let’s examine one path at a time...
     
    THE FACE OF THE RING – The face of any compression ring can have many characteristics that may help or hinder cylinder sealing. The profile (barrel, taper..etc) can vary in many different ways that help the ring stay seated through piston rock over. Face coatings can also make a substantial difference with cylinder sealing depending on your cylinder wall material.
     
    THE SIDES OF THE RING – The side surfaces of the ring, that is the surfaces that seat against the piston flank itself are often overlooked but equally as important in sealing an engine. Simply, the flatter and smoother these sides are, the better they will seal against the piston and stop any blow-by from traveling around the ring land and into the crankcase.
     
    THE END GAP – Here is the correlation...the larger the end gap, the more blow-by and power reduction your engine will see.
     

    Lets examine the strokes in a four stroke engine and the importance that cylinder sealing means to each...

    INTAKE – On any naturally aspirated engine, the better the rings are sealed inside the cylinder and against the piston, the more intake charge (air and fuel) will fill the combustion chamber. Ring seal is the only thing in a normally INTAKE E aspirated engine that draws air / fuel into the cylinder.


    Intake
     

    COMPRESSION – The better the engine is sealed on the compression stroke, the higher the percentage of intake charge that previously filled the cylinder will be utilized. Ring seal is the only thing preventing the charge from leaking past the piston and into the crankcase.
    .


    Compress
     

    POWER – During this explosive event, the more explosion the rings keep above the piston, the higher the force will be COMPRESS. exerted downward on the piston, resulting in more torque and horsepower.


    Power
     

    EXHAUST – The more efficiently the cylinder disposes of exhaust, the more that event in overlap, will help prime the intake stroke for cylinder filling.


    Exhaust
    SIMPLY STATED... AN INCREASE IN PISTON RING SEAL RESULTS IN HIGHER VOLUMETRIC EFFICIENCY WHICH EQUALS INCREASED TORQUE AND HORSEPOWER.

    Total Seal® has worked hard trying to address each of the circumstances above. We have developed a number of separate ring lines from Gapless® to Diamond Finish™, all intended to improve the sealing of whatever engine you may have. Please look through our catalog, call and ask questions, and Total Seal will work with you to decide which ring set might be right for your situation.
